1
00:00:13,310 --> 00:00:16,940
When you're school, we often get asked to make a choice.

2
00:00:17,660 --> 00:00:25,040
Is it Shakespeare or the second law of thermodynamics or DNA rulings?

3
00:00:25,040 --> 00:00:29,570
Or relativity? Or you all? Or only science?

4
00:00:30,710 --> 00:00:39,860
When I was at school, I was deeply frustrated being asked to make such a choice when I was in school.

5
00:00:40,220 --> 00:00:44,390
I started learning the trumpet and I really enjoyed doing that orchestra as I sang

6
00:00:44,390 --> 00:00:49,910
in the choir here in Los Angeles to come up to Boyd employees to do concerts.

7
00:00:50,990 --> 00:00:55,730
I didn't go to theatre, enjoyed doing theatre at school, and so I really enjoyed the artistic side.

8
00:00:56,930 --> 00:01:01,159
But around the same time as I was starting to learn the trumpet, that was amazing.

9
00:01:01,160 --> 00:01:03,230
I also fell in love with the world of science.

10
00:01:03,830 --> 00:01:11,240
I loved the idea of mathematics being this amazing language, destroying the world around us, where we come from, where we need to go next.

11
00:01:12,080 --> 00:01:18,020
The world of science was very exciting and I find it very difficult to decide which route to go.

12
00:01:18,650 --> 00:01:24,260
And I got frustrated by this kind of request that I should make some sort of choice.

13
00:01:24,860 --> 00:01:33,379
Now, I said I was waiting for my malkani tables and my sales and my trumpet, so I chose the mathematical reasons.

14
00:01:33,380 --> 00:01:37,100
And so here I am, a professor of mathematics at university offices.

15
00:01:37,490 --> 00:01:41,389
But I've always kept the contact with the artistic world.

16
00:01:41,390 --> 00:01:48,020
And, and actually as time has gone on I realised is really this is a false dichotomy,

17
00:01:48,380 --> 00:01:53,990
but actually there's much more in common between the two disciplines of art and science.

18
00:01:54,200 --> 00:01:58,520
And in a way, I think mathematics forms a sort of bridge between the two.

19
00:01:59,090 --> 00:02:08,329
So what I want to do in this lecture is to explore some of my favourite artists and some of the things that they love creating.

20
00:02:08,330 --> 00:02:12,440
And I want to show you that actually the structures that they are drawn to

21
00:02:12,860 --> 00:02:17,660
are often very similar to the structures and I'm fascinated in a soft tissue.

22
00:02:18,260 --> 00:02:22,940
So I called my answers on caves and actually secrets, mathematicians and those.

23
00:02:22,970 --> 00:02:27,620
In a sense, I think they're doing mathematics in disguise.

24
00:02:28,250 --> 00:02:36,860
So my name starts with one of the arts, which traditionally has a big connection with mathematics, and that's the arts of music.

25
00:02:37,850 --> 00:02:42,499
I think a lot of people have thought about connections between music and mathematics,

26
00:02:42,500 --> 00:02:48,469
and probably here in the department we probably could gather an orchestra from the professor's because there seems

27
00:02:48,470 --> 00:02:54,080
to be such an idea that trumpets that there are other instruments here that we could have in our orchestra.

28
00:02:54,410 --> 00:03:03,350
But as the secret mathematician I Chazen from the World of Music is actually a 20th century composer and one of my favourite composers.

29
00:03:03,860 --> 00:03:12,319
Olivier Messiaen and Olivier Messiaen was obsessed in mathematics and put a lot of mathematical structures in science.

30
00:03:12,320 --> 00:03:17,150
He's use sometimes consciously, but at other times actually subconsciously.

31
00:03:17,570 --> 00:03:20,700
That that's one of my favourite pieces of the late game ideas.

32
00:03:20,990 --> 00:03:26,030
He very deliberately uses Mass to create a very interesting effect.

33
00:03:26,570 --> 00:03:31,070
It's called the cortex at the end of time. It was a piece that he wrote swans.

34
00:03:31,070 --> 00:03:40,190
He was a prisoner of war during the Second World War and in a prisoner of war camp there he made pianos a rickety upright piano.

35
00:03:40,880 --> 00:03:44,840
There was a violinist, Vanessa Specialist in the camp as well.

36
00:03:44,840 --> 00:03:51,079
And so each composer's quartette for but the form it was at a very desperate time.

37
00:03:51,080 --> 00:03:54,649
And so the piece really captures a sense of unease.

38
00:03:54,650 --> 00:03:59,780
And also in the first movement, it's listen to a crystal mason.

39
00:03:59,780 --> 00:04:05,030
I wanted to capture a sense of never ending time, of things, never quite finishing.

40
00:04:05,580 --> 00:04:13,340
And what's amazing is that to use a mathematical trick in order to create this effect and only is a never ending time.

41
00:04:13,940 --> 00:04:18,740
So the piece starts actually with the clarinets and the advantage, says Birds.

42
00:04:19,370 --> 00:04:24,140
Messiaen was very obsessed with things used to collect these and put them into his music,

43
00:04:24,860 --> 00:04:30,410
but the piano was where the amazing mathematical structure begins to appear.

44
00:04:31,610 --> 00:04:35,210
So this kind of balance actually has a huge lack of passages.

45
00:04:35,600 --> 00:04:44,270
So the catalogue starts as a rhythm sequence, which is 17 notes, a rhythm which then just repeats itself again and again.

46
00:04:44,270 --> 00:04:47,720
So the 17 notes of rhythm get repeated again and again.

47
00:04:48,200 --> 00:04:55,249
But the harmonic sequence, he's got 29 chords, which again repeat themselves through a whole piece.

48
00:04:55,250 --> 00:04:59,330
You get to 29 chords and then you hit 29 chords again and again.

49
00:05:00,050 --> 00:05:07,460
But the for these numbers, 17 and 29, these are examples, the primal, indivisible numbers.

50
00:05:07,670 --> 00:05:11,209
And this choice is very deliberate because the.

51
00:05:11,210 --> 00:05:16,370
1729. Short. The rhythm and the harmony just came out of sync.

52
00:05:16,370 --> 00:05:21,710
Inadequate all back into place until you've heard 17 times 29.

53
00:05:21,890 --> 00:05:26,500
Cause what are we talking the pieces that sound so impressive?

54
00:05:26,780 --> 00:05:29,990
Very challenging on fundamentals he would have had this effect.

55
00:05:30,020 --> 00:05:33,169
So 70 notes of the rhythm sequence.

56
00:05:33,170 --> 00:05:39,010
They start with crotchet, crotchet crunches. And then he goes, It's nice, syncopated rhythm ending with a man.

57
00:05:39,020 --> 00:05:44,690
And then after the red line you sing it properly. Crunchy crotchet of his syncopation, exactly the same rhythm.

58
00:05:44,960 --> 00:05:49,010
The passages exist throughout the whole piece by volume sequence.

59
00:05:49,010 --> 00:05:53,690
The 29 holes go all the way out to here, and then you see the same cool sampling again.

60
00:05:54,620 --> 00:05:58,190
And this destroys of the primes. It gives you the sense of unease.

61
00:05:58,400 --> 00:06:04,700
I mean, it's very difficult to balance the message using these lines as you listen to the piece,

62
00:06:05,420 --> 00:06:11,750
but you certainly get the effect of the unease that he's trying to create and the sense of times that are going on.

63
00:06:12,170 --> 00:06:15,499
So he's good at the end of time, the opening.

64
00:06:15,500 --> 00:06:18,920
So let's listen to these crimes, 17 and 29 taking effect.

65
00:06:37,430 --> 00:06:40,570
That's 17 minutes. Mm.

66
00:06:40,580 --> 00:06:44,780
No. Cause I'm still working their way through the 29.

67
00:06:46,480 --> 00:06:57,770
The civil rights. And I was on the line cause they said they started it in by the rhythm, the place.

68
00:06:58,740 --> 00:07:02,610
And so they say we go on and on is gone somewhere else.

69
00:07:03,000 --> 00:07:10,350
And I've had these twice on time on the same read the same for the previous.

70
00:07:13,840 --> 00:07:18,430
As intriguing as very often. I think what happens here is that the crimes, crimes,

71
00:07:18,430 --> 00:07:24,910
the things that we're obsessed with here in this department, we don't really understand these numbers at all.

72
00:07:24,970 --> 00:07:29,860
But it is a composer using these appliances and things in his piece of music.

73
00:07:30,610 --> 00:07:31,390
Almost intriguing.

74
00:07:31,510 --> 00:07:40,420
I think the connection between the mathematician and the artist is very often we're responding to ideas that are already there in the natural world.

75
00:07:41,020 --> 00:07:45,250
So you can actually find the same train of the primes in the world.

76
00:07:45,790 --> 00:07:50,349
So it's a very curious cicada which lives in the fires in North America,

77
00:07:50,350 --> 00:07:56,080
which uses violence in a very similar way to the way the machine use them in the cortex at the end of the time.

78
00:07:56,470 --> 00:08:03,010
So here we have the rhythm sequence. 17 notes is the the alpha 17 years.

79
00:08:03,040 --> 00:08:04,930
The second rate is again and again.

80
00:08:05,170 --> 00:08:12,310
So we believe that it has a 17 year life cycle because it it's trying to avoid a predator which has a different periodicity.

81
00:08:12,700 --> 00:08:22,780
So, for example, if the predator appears every six years and the calendar appears every nine years, actually is a bad choice of numbers.

82
00:08:24,110 --> 00:08:28,780
Shows these because things get into sync too quickly, six and nine.

83
00:08:28,960 --> 00:08:32,770
So repeating themselves all the 18 years. So that's a.

84
00:08:33,490 --> 00:08:37,900
Was it a bad choice for the for the cicada? Because they get wiped out very quickly.

85
00:08:38,200 --> 00:08:47,799
But anything else changes in order to survive. Now, explain the sanctuary, because the mission seven and six don't have any common devices.

86
00:08:47,800 --> 00:08:51,070
And you didn't hear this in your piece until you're 42.

87
00:08:51,070 --> 00:08:57,880
And that same pattern amazed so many as pieces of equipment like the rhythm is called,

88
00:08:58,930 --> 00:09:05,140
and that the harmonic sequence is that the predator is using these growing 17 and 29.

89
00:09:05,620 --> 00:09:13,340
He manages to keep them out of sync. And so you get the same effect as is happening in the forests in North America with the cicada avoiding predator.

90
00:09:15,100 --> 00:09:20,730
That's interesting, that's very often mentioned was kind of interesting in mathematics.

91
00:09:20,740 --> 00:09:27,460
It was already known and is sort of pandering in my mind to mathematicians, cabinets of wonders to produce effects in his music.

92
00:09:27,940 --> 00:09:37,210
But interestingly, it isn't always one way traffic. Sometimes it's the artists and musicians who are discovering things before the mathematicians.

93
00:09:37,450 --> 00:09:41,890
And an interesting example of this is this very famous sequence of numbers.

94
00:09:41,910 --> 00:09:49,950
So tell me what the next number is in the sequence. 112358 1321, 34.

95
00:09:49,980 --> 00:09:55,020
This is a very famous sequence where you have to put these numbers together and get the next one in the sequence.

96
00:09:55,590 --> 00:10:02,249
Sequence numbers. One of the lot of birds and these are a very famous sequence which you probably all heard about at some point,

97
00:10:02,250 --> 00:10:06,410
if you read the debate code, you will come across in large numbers.

98
00:10:07,160 --> 00:10:16,050
The Golden Girls. You know this because she is 12th century Italian mathematician, realise these numbers and very important things in nature.

99
00:10:16,530 --> 00:10:24,959
They explain spirals in pinecones or pineapples, the way a snail grows or flowers, for example.

100
00:10:24,960 --> 00:10:30,690
The number of patterns in a flower and invariably is one of these Fibonacci sequence is the one with description.

101
00:10:30,690 --> 00:10:37,829
How he shows how he said off cheesy numbers also tell you how rabbits grow one generation to the next.

102
00:10:37,830 --> 00:10:44,130
So he has this very well sort of mathematical model of how they saw us in a pair of rabbits.

103
00:10:44,370 --> 00:10:54,389
And a pair of rabbits requires one generation, a old one one month in order to mature, in order to be our children, all for that one month.

104
00:10:54,390 --> 00:11:01,050
Then they have another pair of rabbits. So after the third month you go to the rabbits.

105
00:11:01,830 --> 00:11:10,590
The one they just gave birth to requires another month before it matures, before it can have another pan, but the one is already generating dies.

106
00:11:10,590 --> 00:11:16,950
And all of these these problems never die. I mean, this is a classic mathematician's model in rabbits.

107
00:11:16,950 --> 00:11:20,040
This is how you are going to have these incredible patterns.

108
00:11:20,580 --> 00:11:24,899
But, ah, what criminology was interesting. Okay, it's quite complicated.

109
00:11:24,900 --> 00:11:29,180
It sort of sets off. But then you quickly realise what capacity is the work?

110
00:11:29,400 --> 00:11:36,720
How many rabbits are one generation to the next? You just add it to previous generations together and that is the answer.

111
00:11:38,220 --> 00:11:44,370
But actually these numbers should not be called the given option on this because they were discovered by technology first.

112
00:11:44,640 --> 00:11:51,660
In fact, they were discovered slightly involved in Archie by artists, musicians and poets in India.

113
00:11:52,350 --> 00:11:59,639
And they were aggressive in trying to understand what sort of rhythms they could create with a mixture of long and short beats.

114
00:11:59,640 --> 00:12:03,660
So the poets was interested in long short beats and musician as well.

115
00:12:04,470 --> 00:12:10,560
And so pretty well how many rhythms he might say, you go for beats in a bar, you can have a long beat,

116
00:12:10,560 --> 00:12:18,000
which is an unknown to beats, or so that is one of the typical possibilities, but it will even be for short.

117
00:12:19,950 --> 00:12:25,530
Or you could do short or long, short or long.

118
00:12:26,950 --> 00:12:32,109
So they were falling into different rhythms that they could mine. But what if I had eight beats in the ball?

119
00:12:32,110 --> 00:12:36,220
How many different rhythms can I make out of these long and short beats?

120
00:12:36,880 --> 00:12:44,490
So even can all these. But I quickly realised that there's a consequence of this, and the pattern is exactly the same sequence.

121
00:12:45,070 --> 00:12:48,100
Because you know what? If I want five pieces. What do I do?

122
00:12:48,280 --> 00:12:57,010
I take all of the rhythms for beats in the bar and I sure beats or I'm going to take 1 to 3 listenable and am only those.

123
00:12:57,340 --> 00:13:04,110
So you see great. A little bit of rhythms with volume. So I take the ones before me and assured me of three weeks and I will repeat, you know,

124
00:13:04,360 --> 00:13:08,560
the two numbers before give me how many different rhythms there will be with points.

125
00:13:08,890 --> 00:13:11,260
And so these Indian mathematicians,

126
00:13:11,830 --> 00:13:19,540
musicians and poets actually have understood that these numbers are very powerfully working out all the different possibilities of rhythms.

127
00:13:19,540 --> 00:13:25,420
And so, as is the magic already in the work. Sandra Before the dance, you have a roadmap.

128
00:13:25,660 --> 00:13:34,629
So, so as you may think, the Alexandra number is not numbers, but I think it's intriguing that his analysis is interesting.

129
00:13:34,630 --> 00:13:43,000
What are the possibilities in that particular art and arriving at some numbers, which are some of the most famous numbers in the whole of mathematics?

130
00:13:44,410 --> 00:13:48,910
So the connection that I talk about so far is about rhythm and counting.

131
00:13:48,910 --> 00:13:54,280
And actually one of the famous quotes about connection between mathematics and music relations.

132
00:13:55,150 --> 00:14:01,130
LYDEN It's one of the inventors of calculus once famously said music is the pleasure of the human mind,

133
00:14:01,150 --> 00:14:05,709
experiences and counting without the wind discounts thing.

134
00:14:05,710 --> 00:14:09,600
Actually, the trumpeter and an orchestra spent a long time counting balls.

135
00:14:10,260 --> 00:14:16,299
We all have. But I think there's much more connection between the two.

136
00:14:16,300 --> 00:14:20,020
And it's about the idea of saying Who decides?

137
00:14:20,710 --> 00:14:26,590
When you listen to music, you'll find you're looking out for the patterns that connect a sequence you just said the one that's,

138
00:14:26,800 --> 00:14:31,690
you know, how has it changed? What's the connection with what you just said and how that changed into something else?

139
00:14:32,500 --> 00:14:38,620
And actually, if you talk to a composer, they will say that what is very helpful is that language in mathematics.

140
00:14:38,890 --> 00:14:42,220
So employing interesting structures, interesting ways of changing things.

141
00:14:42,490 --> 00:14:46,090
Here's Stravinsky writing about his composition.

142
00:14:46,240 --> 00:14:51,520
The musicians you find in mathematics a study as useful and as a learning or

143
00:14:51,520 --> 00:14:57,040
another language is complex mathematics seductively just below the surface.

144
00:14:57,760 --> 00:15:05,950
Certainly he was writing at a time when there was a very mathematical approach to transforming music which is still going on,

145
00:15:05,950 --> 00:15:11,230
should make sure that it was really trying to disrupt this idea of tonal music.

146
00:15:11,950 --> 00:15:17,169
And he wanted an idea breaking away from the idea of major, minor scales.

147
00:15:17,170 --> 00:15:25,620
And he said, Well, why don't we consider the 12 notes that make up the chromatic scale and all equipment as equally valued?

148
00:15:26,360 --> 00:15:30,550
And then he said, Well, it is going to throw this structure away. You need to put new structure in.

149
00:15:30,850 --> 00:15:33,640
And that new structure came very much from mathematics.

150
00:15:34,090 --> 00:15:40,810
So we'll go on to show what the date was to say, Hey, will you do one sort of a permutation of these 12 notes?

151
00:15:40,830 --> 00:15:47,470
You arrange them in some interesting order, which makes some choose some some theme which is appealing to you.

152
00:15:47,890 --> 00:15:52,420
But then you use mathematics to transform that theme and make variations.

153
00:15:53,140 --> 00:15:57,940
And so what he does is to apply, first of all, a sort of translation.

154
00:15:57,940 --> 00:16:02,590
So you take a well-known theme and you just push all of the next up by one note.

155
00:16:02,770 --> 00:16:09,760
And over the top, one of the top is important. And also you keep on pushing these, knowing something anyway, all come down to the bottom.

156
00:16:10,090 --> 00:16:16,210
You get 12 different new themes which are connected to each other because of this mathematical operation.

157
00:16:16,660 --> 00:16:24,070
But you can do other things as well. You can adjust reflected in two lines instead of just playing the theme backwards in some sense.

158
00:16:24,790 --> 00:16:32,139
Or you can write inverses. So you turn this sort of theme upside down by natural things like that.

159
00:16:32,140 --> 00:16:34,870
For example, Bach used a lot in his music,

160
00:16:35,050 --> 00:16:45,880
but this is a very systematic approach to these 1210 rows using these mathematical operations which generate the power to create difference 1210 rows.

161
00:16:46,000 --> 00:16:48,130
We could all have some interconnection with each other.

162
00:16:48,370 --> 00:16:54,879
A brain and a composer would be intrigued by finding some particular 1210 row where when you make these operations,

163
00:16:54,880 --> 00:16:58,840
there seems to be some interesting connections and patterns that emerge.

164
00:16:59,050 --> 00:17:08,140
And then this would be your product, which in songs composing I see as an acquisition, you know, this is a symmetrical operation being wrong.

165
00:17:08,440 --> 00:17:16,510
I guess I would say this was the deal revealed itself across the site through order to acting on this musical scene.

166
00:17:16,820 --> 00:17:22,120
Well, not only composers say, but interestingly enough,

167
00:17:22,150 --> 00:17:29,980
Maximus actually was somebody who loves this mathematical approach to to generating interesting ideas.

168
00:17:30,820 --> 00:17:38,710
And there's a beautiful example of Messiah actually rediscovering a mathematical structure,

169
00:17:39,220 --> 00:17:42,970
but not realising he was drawn to this structure for extended reasons.

170
00:17:43,360 --> 00:17:52,710
What he did was to take to 1210 rows, and he found rather useful in a structure that he uses to generate this piece.

171
00:17:52,720 --> 00:18:03,370
It's funny to say that kind of in the film too, but if you consider these objects mathematically, they had to pay attention to all 12 things.

172
00:18:04,060 --> 00:18:08,350
And actually if you generate, you can think of them as kind of shuffles as well, of course.

173
00:18:08,560 --> 00:18:14,250
And we then combine these suppose to see what all the different combinations are like.

174
00:18:14,270 --> 00:18:20,110
Actually, an object is symmetrical objects, which is only discovered at the end of the 19th century.

175
00:18:20,110 --> 00:18:27,050
And it's a very interesting design, one where essentially the mathematicians include the massive group of order out.

176
00:18:27,580 --> 00:18:33,250
We have a periodic table of symmetry, a lot of the symmetry falling passes,

177
00:18:33,250 --> 00:18:40,870
but there are 26 what we call sporadic groups of symmetry, which are very strange anomalies.

178
00:18:41,350 --> 00:18:43,320
And this what?

179
00:18:43,520 --> 00:18:55,459
12 is one of the first this out and I got some interesting connections with Kobe Gary but here we find missing reselling for purely aesthetic reasons.

180
00:18:55,460 --> 00:19:02,450
He found these 1210 rose interesting in a way that they combined and that was his motivation for the choice

181
00:19:03,260 --> 00:19:09,590
and grace is beautiful piece but actually what he's created is a match but all didn't know what was in it.

182
00:19:09,620 --> 00:19:14,599
We can see in three dimensions. It's a sexual object that lives in very high dimensional space.

183
00:19:14,600 --> 00:19:17,960
We need a language or mathematics to be able to articulate it.

184
00:19:18,260 --> 00:19:24,080
But weirdly, his message in articulating it, not using mathematics, but using music.

185
00:19:24,440 --> 00:19:27,590
So I can't show you this natural object. You can listen to it.

186
00:19:58,330 --> 00:20:04,540
I think my title is one of these things.

187
00:20:04,540 --> 00:20:09,069
And does this look like frantic? So it takes a little bit of time to get accustomed to.

188
00:20:09,070 --> 00:20:15,850
But I think Siri is an intriguing example of a musician being drawn to a mathematical structure purely for aesthetic reasons.

189
00:20:16,510 --> 00:20:22,990
There's a number of my favourite 20th century composers that used some actual structures in his composition.

190
00:20:23,140 --> 00:20:26,660
This is actually symmetrical structure that you can see.

191
00:20:27,910 --> 00:20:31,450
The composer is, yes, the monkeys. He's a great composer.

192
00:20:31,660 --> 00:20:41,590
He is using these for cello. And the variations are done by using a particular central project, which you can see.

193
00:20:41,590 --> 00:20:47,560
So I want you to listen to this piece of music and see what some actual object is conjured up.

194
00:20:47,780 --> 00:21:12,830
Any lines? You.

195
00:21:20,480 --> 00:21:23,030
Anywhere. You get a smattering of objects on the pairing and.

196
00:21:25,720 --> 00:21:33,340
When I was in my cube all the time, all pushed to do that, but I did a little bit on there.

197
00:21:33,340 --> 00:21:37,299
I probably need to buy you more because the ways in I'll just use the symmetries of the

198
00:21:37,300 --> 00:21:42,790
cube is that only eight corners of the cube he puts musical in is the child playing.

199
00:21:42,790 --> 00:21:50,410
So for example, you heard a second. So with less and the music, I was just like, turns the bow upside down and slaps the strings with the woods.

200
00:21:51,010 --> 00:21:53,800
And that's an empty slide is put on. The pawn is the cube.

201
00:21:53,980 --> 00:22:01,390
There's actually a second to controlling the amount of time spent on each of these ideas and each new variation.

202
00:22:01,930 --> 00:22:09,700
He does a symmetry of the cube which tells him a new sort of constraints in order to compose the next variation.

203
00:22:09,700 --> 00:22:11,700
So you probably cheats the guy.

204
00:22:11,720 --> 00:22:17,070
You had one of the variations because you only start to hear the symmetries of the key once you get more of these things.

205
00:22:17,830 --> 00:22:24,250
But it is. Szymanski used to write, actually, that I could only be created under huge constraints.

206
00:22:24,730 --> 00:22:29,310
And so he used to like this idea as a matter of putting some constraints.

207
00:22:29,440 --> 00:22:35,260
I'm going on, I'm putting this right. And then you let your imagination loose within those constraints.

208
00:22:35,440 --> 00:22:38,470
Symmetries of the cube. I mean, there are eight different possibilities.

209
00:22:38,860 --> 00:22:40,899
There's a lot of different ways to rearrange space.

210
00:22:40,900 --> 00:22:46,780
But any constraint on the signatories of the cube constraints a what a connection between the different.

211
00:22:46,780 --> 00:22:52,660
It's music from one variations to the next as that as an office as well as being a composer.

212
00:22:53,230 --> 00:22:59,130
He was also an architect. He works with my second choice.

213
00:22:59,140 --> 00:23:05,200
I'm secret mathematician, a little bit easier on a committee that was made in Brussels.

214
00:23:05,200 --> 00:23:08,409
And it's interesting that if you look at these designs,

215
00:23:08,410 --> 00:23:16,000
they're actually very similar to some of the manuscripts that he wrote for some of the music that he composed for for the show.

216
00:23:16,210 --> 00:23:23,140
So my second choice for mathematician, as I say, is, look, appreciate and and we're moving out of world architecture,

217
00:23:23,320 --> 00:23:29,799
which again, is one of those arts which by its very nature has had some connection with mathematics.

218
00:23:29,800 --> 00:23:33,730
I mean, you can be as creative as you want, but these buildings have got to stand up.

219
00:23:34,030 --> 00:23:36,999
So you have to have some connection with the world of engineering.

220
00:23:37,000 --> 00:23:42,880
I mean, we put lots of wonderful artistic ideas into the mathematics building here at the University of Oxford,

221
00:23:43,900 --> 00:23:47,740
but we also need to be able to make sure that they actually the piece of doors and say,

222
00:23:47,740 --> 00:23:54,250
I'll put in the place if I look to be a sort of loves using mathematics space,

223
00:23:54,250 --> 00:24:01,990
just the buildings I want to build, but also to supply new ideas and new structures in these buildings.

224
00:24:02,350 --> 00:24:07,470
Back to you. You find lots of architects have had an ideal framing in their background.

225
00:24:07,810 --> 00:24:17,740
Zaha Hadid, for example, she was saying ideas in Iraq before she moved to London and would have they have become an architect.

226
00:24:17,740 --> 00:24:22,870
And you see, for example, if you go to the Olympic Park, it's really a piece of mathematics sitting there.

227
00:24:22,870 --> 00:24:24,640
It's not just a piece of architecture.

228
00:24:25,000 --> 00:24:34,330
Local museum is very fascinating is anywhere near the technology numbers and golden ratio and actually a way to tax forces

229
00:24:34,780 --> 00:24:41,110
rhythms inside a building and he writes rhythms apparent to the point and clear in their relations with one another.

230
00:24:41,230 --> 00:24:49,570
And these rhythms are the vagaries of human activities. They resound in man by a mechanical inevitability, the same volume inevitability,

231
00:24:49,720 --> 00:24:55,660
which of course, is very similar to the golden section children, old men, savages and alertness.

232
00:24:56,350 --> 00:25:01,690
And so he loves put in this idea of something that we've all been drawn to as a thing,

233
00:25:01,690 --> 00:25:05,349
which we find is that it can be pleasing when she sees the idea of something

234
00:25:05,350 --> 00:25:10,420
called the golden ratio as you build golden ratio out of these Fibonacci models.

235
00:25:10,720 --> 00:25:19,270
And so as you look at what they did was not to use the numbers that we see already in the rhythms, but as a sequence of numbers.

236
00:25:19,270 --> 00:25:22,990
And these are the kind of ratios he used in the buildings that he produced.

237
00:25:23,920 --> 00:25:34,570
He called them Simple Solutions in his book. And you can see that often while there's the same rule applies to 0.03 plus 0.70 is 1.13.

238
00:25:34,600 --> 00:25:41,229
This same rule generates the numbers in the sequence and essentially the same with what you call multiply.

239
00:25:41,230 --> 00:25:47,320
Now he believe that these ratios and something that goes back to Leonardo the auto also believe

240
00:25:47,320 --> 00:25:54,130
that the these the ratios inside the body were connected with these seven arching numbers.

241
00:25:54,790 --> 00:26:01,390
And so he uses ratios inside of body the single one to an answer to construct these buildings.

242
00:26:01,690 --> 00:26:07,749
And if I asked you if you use these ratios, you very quickly get this thing that he referred to,

243
00:26:07,750 --> 00:26:12,670
the golden ratio, because, for example, if I make a building, I use it in all this.

244
00:26:12,680 --> 00:26:17,890
I have a little one by one room and I want to build in that room.

245
00:26:18,250 --> 00:26:22,240
So I go when I got home, I was looking to add another one by one room onto that.

246
00:26:22,750 --> 00:26:29,830
Well, now I will add to it so I can add it to. To answer this one out of the like three because one side is like three.

247
00:26:29,840 --> 00:26:37,330
So I had a 3.3 ones that 5.1 and as we build up the rooms, they get bigger and bigger generator for the previous room.

248
00:26:37,430 --> 00:26:47,060
So you get this rectangle which is closer and closer to this rectangle, which we call this perfect rectangle, the rectangle with golden ratio.

249
00:26:47,460 --> 00:26:58,460
You have a lovely spiral, which is, which is why the Fibonacci numbers tend to lead to natural structures with side rows inside.

250
00:26:59,480 --> 00:27:07,160
And so the golden ratio is a rectangle. If you do this, then it's a rectangle which has this particular relationship between the sides.

251
00:27:07,160 --> 00:27:12,560
So it's a short distance, the ratio of the longest side to the shortest size,

252
00:27:12,770 --> 00:27:17,630
if that is just the same as the ratio of the sum of the two sides the longest.

253
00:27:18,800 --> 00:27:26,060
Then for some reason we find that the most aesthetically pleasing rectangle is called the golden ratio has a lot of arbitrary properties,

254
00:27:26,060 --> 00:27:34,730
especially when you use it in buildings. So already the ancient Greeks knew about the golden ratio and its kind of special properties,

255
00:27:34,730 --> 00:27:38,600
and it's believed that, for example, the construction of some of the great buildings,

256
00:27:38,600 --> 00:27:45,590
the Parthenon in Athens, it's believed that hidden inside there are a lot of uses of this idea of the golden ratio,

257
00:27:46,340 --> 00:27:50,719
but luckily they use these movies and series to do the same thing.

258
00:27:50,720 --> 00:27:58,200
So you would try and generate all the out of these smaller numbers which would somehow have these aesthetically pleasing ratios.

259
00:27:58,200 --> 00:28:02,390
So one of the most famous examples is actually in Marseille.

260
00:28:02,480 --> 00:28:12,260
This is a city you have years where if you look at the ground plan for all of the rooms, they have this kind of similar spiral rings inside.

261
00:28:12,590 --> 00:28:17,090
Although I actually you a place that unfortunately was a was an aesthetically pleasing building.

262
00:28:17,090 --> 00:28:21,909
But actually residents say it's actually going to set a very nice sense of growth inside.

263
00:28:21,910 --> 00:28:27,319
It's not as intriguing, you know, how much is this culturally specific?

264
00:28:27,320 --> 00:28:32,479
Because certainly the waste tends to like the golden ratio.

265
00:28:32,480 --> 00:28:41,389
But actually in the east, especially in Japan, it's found that they see responds to a rectangle with slightly different portions.

266
00:28:41,390 --> 00:28:46,220
So it's a rectangle which is secondly a similar ratio.

267
00:28:47,270 --> 00:28:50,299
So racism is a similar issue. What do you think?

268
00:28:50,300 --> 00:28:57,470
Actually a rectangle which is in the relationship of one square root of two as your piece of A4 paper.

269
00:28:57,740 --> 00:29:07,880
For example, in this ratio it has a nice property, an able piece of paper and I would be able to for in to that has exactly the same proportions.

270
00:29:08,360 --> 00:29:09,920
So this is a very nice rectangle.

271
00:29:10,010 --> 00:29:18,590
That's why you have 83, 80 to a one, they're all the same ratio but before one in hall and you guys still had one two square root of two.

272
00:29:19,160 --> 00:29:25,430
This isn't a similar ratio. The same ratio is you need to add another one by one room on the site.

273
00:29:26,510 --> 00:29:32,180
So this is a rectangle which is a one or two plus one.

274
00:29:32,600 --> 00:29:37,200
And other cultures like these are very aesthetically pleasing ratio.

275
00:29:37,490 --> 00:29:43,940
For example, buildings in Japan, this sort of pagoda is slightly sited in many different places.

276
00:29:44,060 --> 00:29:48,790
This particular ratio kind of more elongated rectangle.

277
00:29:49,400 --> 00:29:53,210
I got to be very busy design to rank them up for you.

278
00:29:53,600 --> 00:29:57,020
Now let's do a little survey of the audience just to see.

279
00:29:57,620 --> 00:30:04,550
And you look at these two rectangles, which one do you find aesthetically pleasing?

280
00:30:05,550 --> 00:30:12,980
So you can put your hand up if you find that the top rectangle aesthetically pleasing of these two.

281
00:30:17,170 --> 00:30:20,650
That's why it's quite a large proportion of you got your hands out and.

282
00:30:21,820 --> 00:30:30,010
Okay, what about the lower ones? I actually oh my gosh, that's a kind of 5050 split, I would say.

283
00:30:30,010 --> 00:30:35,639
That's very intriguing and sort of a mixture of cultures here.

284
00:30:35,640 --> 00:30:38,799
And I don't think there was any particular bias on one side or the other.

285
00:30:38,800 --> 00:30:45,610
So maybe we should do more research into this and exploring whether the old ratio this is the first

286
00:30:45,610 --> 00:30:55,299
place on this idea of ratio is actually a use in architecture is not used in the 20th century like it.

287
00:30:55,300 --> 00:31:07,030
In fact, if you go to Canada, one of the great architects of the past, he loved using the idea of ratios and important ratios.

288
00:31:07,030 --> 00:31:14,049
And so I think it's actually why you get a sense of this amazing equation.

289
00:31:14,050 --> 00:31:22,000
You know, whenever I go to Bologna dinner and there's a kind of feeling of perfection about the space that your your visit

290
00:31:22,120 --> 00:31:30,710
and all this is because what Bologna loved doing was using ratios which are called operation relationships.

291
00:31:30,720 --> 00:31:38,290
And in fact, so this relates very much to the musical harmony, the notes that we find all are also in a whole number ratio.

292
00:31:38,410 --> 00:31:40,990
So you've got strings on the sides of the roof and.

293
00:31:48,760 --> 00:31:56,520
So if you take the strings, the length of the rooms inside of a longer villa because they're in a whole generation to each other,

294
00:31:56,530 --> 00:31:59,719
you pop them, you get actually notes, which we find very harmonious.

295
00:31:59,720 --> 00:32:04,150
So a 1 to 2 relationship is two notes which are in an octave.

296
00:32:04,420 --> 00:32:08,320
Oh 2 to 3 relationship is two notes which are imperfect things.

297
00:32:09,040 --> 00:32:18,520
So as you apply this thing sort of phrasing this musical harmony, all the reforms through across cultures in India,

298
00:32:18,760 --> 00:32:24,670
in Far East or in the West, this perfect faith is very often the key, which all music is great.

299
00:32:25,270 --> 00:32:31,299
Here we go to the and music is architecture is often called phrase music because

300
00:32:31,300 --> 00:32:36,060
it's got these lovely alterations it's a dreamy both melody and look blues.

301
00:32:36,100 --> 00:32:42,040
Yeah. I mean it needs to be very similar so mathematicians have work and it wasn't attribution is interesting

302
00:32:42,040 --> 00:32:46,780
and seeing what all the different possibilities are to make out this particular structure.

303
00:32:47,050 --> 00:32:52,330
So love is taking the whole number ratios and arranging them and seeing what different possibilities are.

304
00:32:52,630 --> 00:32:56,050
Luca You like something a little bit less symmetrical?

305
00:32:56,050 --> 00:32:59,620
So he's trying to use his series Lose and see what he's learned.

306
00:32:59,620 --> 00:33:06,759
I might kind a slightly asymmetrical here to the bird's eye view was natural variant

307
00:33:06,760 --> 00:33:10,930
of feather but argues that it's a more modern better look at these days which

308
00:33:10,930 --> 00:33:16,390
uses these different ratios and it's interesting actually want to amend that

309
00:33:16,690 --> 00:33:21,660
look I used we tried all of these ratios inside them as an intuitive resonance,

310
00:33:22,180 --> 00:33:25,060
kind of asymmetrical version of Vitruvian Man.

311
00:33:25,270 --> 00:33:34,630
Leonardo's picture, I think you see this Vitruvian Man is a very, very well known image, beautiful image.

312
00:33:35,020 --> 00:33:38,080
But actually this is a solution to an architecture problem.

313
00:33:39,700 --> 00:33:43,629
Vitruvius was a Roman who wrote about architecture.

314
00:33:43,630 --> 00:33:49,100
Andrew St James A lot of relationship between ratios in the body and the ratios inside a building.

315
00:33:49,120 --> 00:33:55,270
A building works and it somehow reflects the humans that are inside and occupying that building.

316
00:33:55,630 --> 00:33:59,140
And so he believed there was a nice way that you could reduce that.

317
00:33:59,140 --> 00:34:04,140
It was a nice way to either arrange a circle and a swing such the human body.

318
00:34:04,150 --> 00:34:09,010
But inside both of them and for generations, people were trying to solve this puzzle.

319
00:34:09,580 --> 00:34:17,230
You could see images before Leonardo's where they find a sort of belly button is a common centre, both set on the square.

320
00:34:17,260 --> 00:34:26,950
You get really strangely proportioned humans and it was in a this idea actually to shift the centre so the centre of the circle

321
00:34:26,950 --> 00:34:39,129
is pretty much on value but that's where it should be down its centre is sort of the idea is that you could use these ratios.

322
00:34:39,130 --> 00:34:43,240
They actually create a building which resonated with these images.

323
00:34:43,900 --> 00:34:49,780
Now I get to move in ways in which these individual, individual moments and place.

324
00:34:49,900 --> 00:34:52,030
Where you going to see lots of geometry works.

325
00:34:52,090 --> 00:35:01,180
I could easily have chosen Leonardo as a secret mathematician, but is he really somebody who bridges the arts and sciences?

326
00:35:01,180 --> 00:35:09,999
But I think modern art is something that only Salvador Dali thinks of his paintings.

327
00:35:10,000 --> 00:35:14,379
It is full of lots of different ideas, both for mathematics and science.

328
00:35:14,380 --> 00:35:20,200
There are elements of DNA appearing in there. You are very obsessed with the ideas of relatively in time.

329
00:35:20,380 --> 00:35:24,490
It's not easy. There's not a clock sawing off the size of melting away.

330
00:35:24,910 --> 00:35:32,700
And you reference outline of a container fish swimming in sea waters, the cold water bones and hot water science.

331
00:35:32,770 --> 00:35:41,830
And as is the much more enjoyed by his scientists adaptations round to his house rather than the artist to try and find interesting ideas.

332
00:35:42,340 --> 00:35:49,740
But if any basic sound and actually in his paintings you see a lot of different mathematical ideas being exploited.

333
00:35:50,800 --> 00:35:54,150
So this is the image I'm going to show you.

334
00:35:54,400 --> 00:35:59,830
Okay. Which are not matching all the things. I just called that one and on the next slide.

335
00:36:02,140 --> 00:36:05,410
So there's a one who painting who went to the Last Supper.

336
00:36:06,040 --> 00:36:12,070
I see somebody inspired by one of the paintings of The Last Supper.

337
00:36:12,550 --> 00:36:19,380
But actually, he wants the audiences to stage the dinner inside alone.

338
00:36:20,130 --> 00:36:29,170
Though he's an aesthetic, he is interesting because if you go back to the ancient Greeks and they old man is shaping the shape of the universe.

339
00:36:29,740 --> 00:36:36,430
So the idea is this last supper is taking place inside the shape, which is, in a sense, the shape of the universe.

340
00:36:36,910 --> 00:36:42,489
And again, I wanted to bring you that. And it's not just all this flowering.

341
00:36:42,490 --> 00:36:50,410
The mathematicians can be very interesting shapes. Actually, the mathematicians benefited from all this theoretical watching all these things.

342
00:36:50,620 --> 00:36:57,520
If we go back to the Renaissance, we find a huge number of paintings where these symmetrical shapes that he drew.

343
00:36:57,760 --> 00:37:08,710
This is a painting of mathematician Lucy Lucia, actually, as you see on his desk at the Hedren, which he used in the last segment.

344
00:37:10,720 --> 00:37:20,290
But there are other things as well. It's really this strange glass floating of these hall filled with water as well.

345
00:37:20,300 --> 00:37:24,100
And this is an example of a road in Rome. Meet you all together.

346
00:37:24,760 --> 00:37:29,260
So this the mathematicians have discovered it already.

347
00:37:29,300 --> 00:37:37,210
And you can see elements. There are five symmetrical shapes you can make where the faces are all the same shape and arrange the central map.

348
00:37:37,270 --> 00:37:42,220
So they're like even being one of them, the cube and three others then all completely.

349
00:37:42,780 --> 00:37:47,990
So what about if you use different shapes as well?

350
00:37:48,130 --> 00:37:57,010
Okay. So if you think about the classical world that one gets around when the sun is made out of of goods and hexagons,

351
00:37:57,310 --> 00:38:00,520
so they all have the same edge so they can fit together.

352
00:38:00,670 --> 00:38:04,120
But there is an asymmetrical shape made out of pentagons, of hexagons.

353
00:38:04,540 --> 00:38:08,830
So all of to. Okay, how many more than all of these?

354
00:38:08,950 --> 00:38:15,610
How many different ways to put together these objects? And so you use another example is Romeo all together.

355
00:38:15,880 --> 00:38:20,800
It's made out of triangles and swings. I mean, all these triangles this ways together.

356
00:38:20,800 --> 00:38:24,730
In many ways, it's unusual. The challenge was how many more?

357
00:38:25,300 --> 00:38:32,500
So it just over there are 14 different ways that you can piece these flat shapes together to create these shapes.

358
00:38:32,950 --> 00:38:37,060
But actually, for my antiquity, it was kind of lost what these 14 were.

359
00:38:37,150 --> 00:38:40,780
There was some documentation that all these had indeed discovered.

360
00:38:40,780 --> 00:38:45,820
14, But nobody knew about the Renaissance, really, what a small team were.

361
00:38:46,000 --> 00:38:51,610
And I sort of took the skill of the artist who was able to actually represent these shapes on

362
00:38:51,610 --> 00:38:57,370
a canvas over on a page for us to actually go through it and sort of rediscover those motifs.

363
00:38:57,370 --> 00:38:58,130
So, you know,

364
00:38:58,180 --> 00:39:06,420
the mathematicians really had the artists to thank would suddenly try to show how good they were expected to be able to draw these shapes.

365
00:39:06,430 --> 00:39:13,590
And we have a great challenge that from the keyhole to even really show the artist's perspective.

366
00:39:14,770 --> 00:39:24,930
And finally, although it is raising a book quite actually illustrating all of these examples of the way we see symmetrical objects.

367
00:39:24,940 --> 00:39:31,060
Yeah. And so I really wanted some perspective.

368
00:39:31,450 --> 00:39:35,680
And actually Leonardo was used a lot of ideas in his paintings.

369
00:39:36,420 --> 00:39:44,380
I could have easily chose him as my secret mathematician. This is the painting which Dani kind of based his idea on The Last Supper.

370
00:39:44,710 --> 00:39:50,050
And it's there's lots of mysticism about this know secret messages hidden inside.

371
00:39:50,050 --> 00:39:51,430
And there's certainly, I think,

372
00:39:51,430 --> 00:40:01,000
no secret of the fact that being able to use mathematical relationships in order to place design in the placement of something.

373
00:40:01,030 --> 00:40:07,180
So you find lots of golden braziers hidden inside the way this painting is constructed.

374
00:40:07,420 --> 00:40:17,499
And again, probably nowadays, most famous painting by Lisa is believed to have a lot of Fibonacci numbers and ratios in the relation that,

375
00:40:17,500 --> 00:40:22,930
in fact, you see all the Mona Lisa is perhaps hidden in mathematical beauty.

376
00:40:23,500 --> 00:40:27,670
And then sometimes it just means that there are a lot of drawings of Leonardo's

377
00:40:27,670 --> 00:40:32,830
or he looks at face and constructs the face based on these Fibonacci ratios.

378
00:40:33,810 --> 00:40:42,490
And but Dani was interested to see these very classical shapes, but also in a much more modern 20th century shapes.

379
00:40:44,880 --> 00:40:47,910
Image. This is the image that I'm going to talk about.

380
00:40:50,760 --> 00:40:54,209
So don't actually use the same fractals.

381
00:40:54,210 --> 00:40:56,550
Fractals were discovered in the 20th century.

382
00:40:56,550 --> 00:41:06,090
Somehow the shape of chaos is in some words, these shapes recognise these shapes as they have some infinite complexity as you zoom in.

383
00:41:06,780 --> 00:41:15,419
They don't get simpler. So one of the classic examples is a space suit where you have a triangle and then you invite a smaller triangle on that one,

384
00:41:15,420 --> 00:41:16,860
and smaller and smaller and smaller,

385
00:41:17,600 --> 00:41:26,040
as she only uses in a painting, is on the wall where he you think he looks a bit like a face because your two eyes and a nose there.

386
00:41:26,550 --> 00:41:32,220
And he uses like I'm taking a sculpture which looked like this love triangle.

387
00:41:32,220 --> 00:41:37,650
And any side is the eyes and the mouth he puts on another skull.

388
00:41:37,650 --> 00:41:39,750
And then it's like those you can see another skull.

389
00:41:39,770 --> 00:41:47,820
And so it's kind of is the sense of infinite complexity is produced by using this structure, mathematical structure and only this painting.

390
00:41:49,590 --> 00:41:57,960
Actually, fractals were also used, but I'm sort of subconsciously by another famous 20th century painter,

391
00:41:59,430 --> 00:42:08,030
Jackson Pollock, if you remember his paintings, the lovely paintings with all of this paint just dreadful over.

392
00:42:09,300 --> 00:42:12,270
But it maybe would criticise all of this. That's come on my mind.

393
00:42:12,390 --> 00:42:23,010
I got 210 year old girls, tweens and teenage sports fans know something like this, but get these paintings available, you know, £75 million, so.

394
00:42:23,160 --> 00:42:27,520
Sure. Well, it must be doing something wrong, especially with my ten year old girls.

395
00:42:27,520 --> 00:42:34,170
Can't do so. So what is it? It seems that there's a very special quality that these paintings have,

396
00:42:34,320 --> 00:42:40,950
which they had is perhaps a quality that only they have a complexity to examine.

397
00:42:40,980 --> 00:42:45,000
This is very difficult to tell what scale you're looking at this painting.

398
00:42:45,480 --> 00:42:52,650
Here are four different pictures which I zoomed in all over to take up all of this.

399
00:42:52,650 --> 00:43:00,690
I think it's very difficult. I think by the top right hand corner, you can tell that's probably the closest one, but only on the three.

400
00:43:00,710 --> 00:43:06,180
I, I think it's quite hard to tell which is after painting, which is a zoomed in version.

401
00:43:06,510 --> 00:43:13,110
And so pull up is creating this, these trips which had very special quality, they had this fractal quality to it.

402
00:43:13,530 --> 00:43:22,740
And in fact there are people trying to fight. So when you think of a painter and a huge one, but actually it's quite hard to do what it's doing.

403
00:43:23,010 --> 00:43:32,400
And so quite a few tend to be fakes because they don't have this fractal pointing to you can even measures and fractal connections.

404
00:43:32,820 --> 00:43:40,320
And so in different periods it follows crazy prices have different fractal mathematical quality too.

405
00:43:41,040 --> 00:43:48,410
Now the reason Pollock was doing something well, the special grading is this is you have rice specific style raising.

406
00:43:49,500 --> 00:43:54,180
It's kind of very about a balance. So it wasn't very steady.

407
00:43:54,770 --> 00:43:59,490
You you'll see sprinkles and when he was making these paintings he would often be pretty drunk.

408
00:44:00,150 --> 00:44:05,370
I thought it was it's when he's playing his hands, he's actually acting.

409
00:44:05,490 --> 00:44:13,140
You know, if I feel better, I would do this. I'm actually a bit like a pendulum on a very simple pattern and I'm crazy about it.

410
00:44:13,380 --> 00:44:21,660
But if I actually start moving where the pendulum is so caught up to what I was creating something called the chaotic pendulum,

411
00:44:21,870 --> 00:44:25,590
and then the shape is made is actually this flat.

412
00:44:25,920 --> 00:44:29,720
So there is a way to make trying I do this.

413
00:44:32,460 --> 00:44:41,320
It seems to me that's important, which is to set up a positive page on the page about and to move where the actual pages attached to.

414
00:44:41,500 --> 00:44:47,970
And he did decide if this was the only way to get it.

415
00:44:49,440 --> 00:44:58,420
But that is the principle of the book. But it's no use what is coming back suddenly and his obsession with new sites.

416
00:44:59,200 --> 00:45:06,490
He also is fascinated in shapes and applications of creating beyond the three dimensional world that is so visual.

417
00:45:08,320 --> 00:45:19,510
Here's the image since 2000. So it's one incredible painting where he takes a full directional cue.

418
00:45:19,720 --> 00:45:24,940
Now, you know, I don't want to use the idea that in three dimensions,

419
00:45:24,940 --> 00:45:34,090
but what you can do is sit on a ramp or dimensional cue into a three dimensional universe in the same way that Y is a three dimensional cube.

420
00:45:34,120 --> 00:45:37,660
I mean, how do you make a three dimensional cube out of a piece of paper?

421
00:45:37,900 --> 00:45:44,110
What do you agree is what's called the net. So you have four sways, two on the side, you have a cross shape.

422
00:45:44,290 --> 00:45:50,130
And then you can sort of fold this on out and you can create all cube when you do the same thing from three dimensions into order.

423
00:45:50,500 --> 00:45:55,330
So you can have a net of a quarter cube. This is what you're looking at here.

424
00:45:55,840 --> 00:46:04,569
So if we lived in a four dimensional university, a way to connect all of these to the ends in order to be able to create what we want.

425
00:46:04,570 --> 00:46:11,139
I think this we can't do. We can at least have this knit downstairs in three dimensions.

426
00:46:11,140 --> 00:46:14,860
And what would I think she was doing? Don't you find this totally fascinating?

427
00:46:15,010 --> 00:46:17,710
He was a very religious man as as being interested in science.

428
00:46:17,890 --> 00:46:25,720
And the idea of these two intersecting crosses was too much for him and the idea of a fourth dimension, something spiritual beyond our physical world.

429
00:46:26,120 --> 00:46:32,020
So as you choose this shape as the shaped, cruciform, Feustel says amazing painting,

430
00:46:32,200 --> 00:46:39,120
which shows Christ being spied on what's cool this tesseract unwrapped for you.

431
00:46:39,670 --> 00:46:45,370
You can actually see other. There's an architect in Paris who use another way of seeing one dimensional cube.

432
00:46:45,520 --> 00:46:51,669
You can take a shadow of it. And if I think of the small cube inside a larger cube and hear the object in Paris,

433
00:46:51,670 --> 00:46:57,790
use the idea of a shadow, for instance, to create a three dimensional object it's made of yet again.

434
00:46:57,970 --> 00:47:01,270
These are some extraordinary effects.

435
00:47:01,930 --> 00:47:05,840
A We kind of sucks through the whole there.

436
00:47:05,860 --> 00:47:08,889
I mean, it's very weak. It's going to be got to be steel everywhere else.

437
00:47:08,890 --> 00:47:15,950
But it's actually the reason they put this kind of we paint sculpture is to try to sort this wind down.

438
00:47:16,090 --> 00:47:21,760
But I always have to ask, does something weird like opening up a wormhole into the 1970s four dimensional shape?

439
00:47:21,760 --> 00:47:25,770
There actually is, if I have to be careful, it's not the suburbs of Paris.

440
00:47:25,780 --> 00:47:27,880
All right. I think you guys are. Exactly.

441
00:47:29,170 --> 00:47:39,160
I'm going to say it's like all secret mathematician now who actually who's obsessed by the idea in four dimensions.

442
00:47:39,430 --> 00:47:40,960
And he comes from the world of literature.

443
00:47:41,330 --> 00:47:47,650
I think literature is slightly more of a challenge to find connections between literature and the world of mathematics.

444
00:47:47,660 --> 00:47:51,370
Poetry? Yes, certainly the kind of patterns one sees in poetry.

445
00:47:52,870 --> 00:48:01,120
Borges, an Argentinian writer. 20th century, is a choice of my favourite secretive mathematician in the world of literature.

446
00:48:01,680 --> 00:48:07,740
His. He writes about short stories and short stories, a full narration of the ideas of paradox,

447
00:48:07,810 --> 00:48:16,960
the ideas experiencing the nature of space and the beautiful stories and exploring also things on interesting in classical.

448
00:48:18,580 --> 00:48:20,799
I was interested to hear what Wilson thinks. Was he reading?

449
00:48:20,800 --> 00:48:26,200
And it seems that he was certainly interesting reading Bertrand Russell and maybe Von Grey as well.

450
00:48:26,950 --> 00:48:31,240
There's one story in particular which is my favourite school is the Library of Babel,

451
00:48:32,170 --> 00:48:42,490
and it describes a librarian who is trapped in his library, and he spends the short story trying to work out what the shape of his library is.

452
00:48:43,240 --> 00:48:48,399
First of all, he just has his local knowledge of what's the room that he's in is like,

453
00:48:48,400 --> 00:48:54,460
and that the short story opens with a description of what is going on in the universe,

454
00:48:54,550 --> 00:49:03,110
which all the school library is composed of an indefinite and perhaps infinite number of hexagonal diamonds from any one of the hex.

455
00:49:03,520 --> 00:49:06,760
So you can see it's only the upper and lower floors.

456
00:49:07,390 --> 00:49:10,450
So the structure of his library is a little bit like honeycomb.

457
00:49:10,450 --> 00:49:15,370
So each of the rooms is a hexagon and you can guess there are two doors.

458
00:49:15,370 --> 00:49:23,469
So you just go in and out of these hexagons into another hexagon and you can see an upwards through staircase.

459
00:49:23,470 --> 00:49:28,360
There's more axons out there lower down the sort of the libraries also speculates.

460
00:49:28,360 --> 00:49:35,980
Okay, so what that means it's gone forever or is there somehow a wall in the house or something?

461
00:49:36,400 --> 00:49:39,670
So it's an interesting mathematical challenge.

462
00:49:39,840 --> 00:49:46,630
You only know local information. And so anything about clue or structure is something that we study by the ultimate practice.

463
00:49:47,410 --> 00:49:52,959
Now, there are also books. This is a library. It's full of books and books that are in this library.

464
00:49:52,960 --> 00:50:00,220
Kind of interesting because that equals analysis realises they all have parts and they all seem to be the same sort of structure.

465
00:50:00,370 --> 00:50:03,940
Not only that, but it seems to me every single book possible he writes.

466
00:50:04,150 --> 00:50:13,450
So this is a structured each book is a 410 pages, each page 40 lines, and each line is an 80 letters and all graphical numbers.

467
00:50:13,520 --> 00:50:20,419
Nine 2525 The number is a speculate that's actually in his library.

468
00:50:20,420 --> 00:50:27,230
There's every single book possible that ever could be written within this structure, and he believes there's only one.

469
00:50:27,470 --> 00:50:35,870
So each book is unique. So they will be first 410 pages of the complete works of Shakespeare somewhere.

470
00:50:36,130 --> 00:50:42,890
They're also the same axes. So when we actually calculate how many different books there are,

471
00:50:43,280 --> 00:50:52,190
because for the first 25 voices the same amount over another 25 choices, it's either 25 or 35 choices.

472
00:50:52,640 --> 00:50:59,420
For the first two letters of any of these books that you can count the number of letters and work out the different poses,

473
00:50:59,420 --> 00:51:02,480
there always is another 25 choices for each different letter.

474
00:51:02,840 --> 00:51:06,720
So as you remember, we had 80 characters on each line.

475
00:51:06,740 --> 00:51:10,010
So you find the number of things that are possible 25 to the power 80.

476
00:51:11,240 --> 00:51:16,280
But we've got 40 lines so great that some have 40 and there are 410 pages.

477
00:51:16,370 --> 00:51:22,130
So that's we have raised the path for. So there are quite a lot of books in this line.

478
00:51:22,310 --> 00:51:28,940
I think a sense of how many books that are in the observable universe are in fact only ten of the 18.

479
00:51:29,030 --> 00:51:36,110
We believe atoms in the universe made every single atom one of these books ever near.

480
00:51:36,140 --> 00:51:41,750
I can go through all the different possibilities of books. But on the other hand, there's numbers, points,

481
00:51:42,080 --> 00:51:49,190
which means maybe the library means they may be libraries notes they must have an end, or does it have a name?

482
00:51:49,760 --> 00:51:53,149
And here we didn't get into the challenge for the mathematician.

483
00:51:53,150 --> 00:51:57,110
Yeah, okay. How can you have a shape made out of all of these hexagons layers?

484
00:51:57,410 --> 00:52:04,550
And finally now we're getting into the question that many of us consider not our universe, which we know we call the universe.

485
00:52:04,910 --> 00:52:12,770
What is the shape of all universe? If you think about all of us as kids look out into the night skies in these stars,

486
00:52:12,770 --> 00:52:18,770
you guys want to solve random or what does it have all of you and Xena decided?

487
00:52:18,770 --> 00:52:22,669
It's not. That's what the ancient Greeks believe, that they were somehow advanced.

488
00:52:22,670 --> 00:52:26,550
All that we were sitting inside. But that's kind of weird because what's on the other side of that?

489
00:52:26,570 --> 00:52:29,720
I mean, surely we're not living in The Truman Show. That's going to feel great.

490
00:52:29,900 --> 00:52:35,389
Well, maybe we all there. But here is this kind of idea.

491
00:52:35,390 --> 00:52:40,700
Okay, so what we do every year, at some point it is mind we find out what will happen to people together.

492
00:52:40,700 --> 00:52:47,420
Either there's an end going to get out of it. I think the lover thinks that's true because this is all there is.

493
00:52:47,750 --> 00:52:49,280
As the results come up with us,

494
00:52:49,390 --> 00:52:56,990
it is one end of the short stories come up with the idea that we come up with the what possible shape all universe could be good,

495
00:52:56,990 --> 00:53:00,140
as he mentions, to suggest a solution to this ancient problem.

496
00:53:00,620 --> 00:53:08,180
The library is unlimited now has more in any secret and all power to cross into any action.

497
00:53:08,360 --> 00:53:12,650
After centuries, you won't see the same volumes repeated in the same disorder.

498
00:53:13,290 --> 00:53:16,790
I for you, we think the same structure is happening in all units.

499
00:53:17,270 --> 00:53:20,840
So if you keep on going somehow you go back to where you started.

500
00:53:20,900 --> 00:53:24,960
That would be a solution. So some of you might remember playing this game here.

501
00:53:25,070 --> 00:53:29,209
We will be following that. It says, I don't have anything on my mind.

502
00:53:29,210 --> 00:53:33,980
My son did the same last year. It's a beautiful example of the universe.

503
00:53:33,980 --> 00:53:39,860
It's a finite universe on your computer screen. So the universe is just sitting here, but it has this rule.

504
00:53:40,130 --> 00:53:47,090
And if you go to the top of the screen up at the bottom, and if you go off the side of the screen, you reappear on the other side.

505
00:53:47,350 --> 00:53:52,610
So I'm sorry, this is unlimited. If you've ever hit a wall and bounced back, it feels like it just goes on forever.

506
00:53:52,880 --> 00:53:56,660
But it is falling out. So what is the shape of this universe?

507
00:53:56,960 --> 00:54:02,750
Well, we have the luxury of living in three dimensions, and we can actually explore what the shape of this is.

508
00:54:03,080 --> 00:54:09,110
So we can use it that I mentioned to connect this thing up. So ask me what the shape of the universe is.

509
00:54:09,230 --> 00:54:13,550
It's it's actually the shape of a force or a doughnut.

510
00:54:14,180 --> 00:54:17,540
So when you go off the top of the screen about round background,

511
00:54:17,540 --> 00:54:24,979
the bottom as you're going round the inside of the bangle or you go with one end in the other, you come out, the other side is wrapped up.

512
00:54:24,980 --> 00:54:30,870
So the top of the bottom of the screen connected, joining them all and in the left and right hand side of the screen.

513
00:54:31,790 --> 00:54:34,999
So that's drawing those up. And then you see the shape emerging for you.

514
00:54:35,000 --> 00:54:40,310
It's the shape of the course. But we live in three of us with all my story.

515
00:54:40,320 --> 00:54:46,400
So I mean, suppose that this lecture is a walk on you to the spine as we go up to this size.

516
00:54:46,880 --> 00:54:53,510
So how would this work? I mean, this universe, this is not the three which we should be able to about tackle this wall.

517
00:54:53,510 --> 00:54:56,990
It should somehow be our liberty. How do we make it work?

518
00:54:57,290 --> 00:55:01,130
Well, here's trying to what, if anything, asteroids with this root.

519
00:55:01,370 --> 00:55:06,770
So we got the left hand side of the room just magically appeared from the right.

520
00:55:07,490 --> 00:55:12,830
Or what happens if you go through the seed? Well again you should come back is going.

521
00:55:13,480 --> 00:55:18,070
As you can see, they were coming through the floor. So that's game to potential game as well.

522
00:55:18,190 --> 00:55:22,450
And we've got to think we can go. When I go out, the back will actually be attacked.

523
00:55:23,410 --> 00:55:26,739
But you won't find the massive all the angles something.

524
00:55:26,740 --> 00:55:32,560
We had a pair back on stage here. And so this is a model of how our universe can be connected together.

525
00:55:32,760 --> 00:55:37,600
I knew this could have a cyclical nature to it. And then the question is how to treat it?

526
00:55:37,630 --> 00:55:43,480
What does this universe look like? Well, the lights that's coming from the back of my head is what's happening.

527
00:55:43,630 --> 00:55:47,980
The light is going out through the screen here. Would it be appearing as my collected data?

528
00:55:48,100 --> 00:55:52,440
So actually, I can see the back of my head out there and I can see it again and again.

529
00:55:52,450 --> 00:55:57,459
So this is the image, what your unit has and maybe some of those cells we're seeing in the right size.

530
00:55:57,460 --> 00:56:01,570
It's our own sun, but we're seeing it's sort of looped round again and again.

531
00:56:02,320 --> 00:56:06,010
So it is. But this has a shape. Intriguingly, what is this showing?

532
00:56:06,280 --> 00:56:12,540
This is actually well supported shape. I would have to join all of these together.

533
00:56:12,550 --> 00:56:15,910
And what I look at is what's called a in.

534
00:56:15,910 --> 00:56:19,600
For instance, I will get a very high dimensional way.

535
00:56:20,050 --> 00:56:23,060
I, I see that so many times.

536
00:56:23,080 --> 00:56:31,479
I wonder, I can't actually show you the same, but we can use I see this law, but this is actually what Ford has ended up constructing in his library.

537
00:56:31,480 --> 00:56:36,459
By the shape of the library, the way you ended up is you created this void.

538
00:56:36,460 --> 00:56:43,150
I will be right this through this narrative, not realising anything about mathematics of higher dimensional forces.

539
00:56:43,510 --> 00:56:47,559
And actually one of the great breakthroughs in mathematics has happened in the last

540
00:56:47,560 --> 00:56:52,810
few years was a solution with one great conjecture by a Russian mathematician,

541
00:56:53,020 --> 00:56:58,329
Gregory Pope. And what he actually did was to solve the problem of, well,

542
00:56:58,330 --> 00:57:06,770
what are the other ways that we can join up our universe by new this I give you a way of doing that turns into the point of dimensional language,

543
00:57:07,000 --> 00:57:16,540
but there are other ways of doing it. Observe this finite part without any rules or boundaries and permanent solution for the point break.

544
00:57:16,540 --> 00:57:22,540
And there's actually something even in that this is geometric transition conjecture is actually

545
00:57:22,540 --> 00:57:27,040
a list of all the possible universe is that Borges could have used in his short story.

546
00:57:28,450 --> 00:57:31,900
If I recently I used this idea of the library available.

547
00:57:32,140 --> 00:57:35,709
This is a few years ago. I just love this story.

548
00:57:35,710 --> 00:57:40,900
And I worked with the choreographer and composer today to try and explore as

549
00:57:41,230 --> 00:57:46,780
creating an artistic work which combines mathematics and choreography in music.

550
00:57:46,780 --> 00:57:55,300
And so this is actually I ended up dancing, which is kind of my first imaginary little clip of me dancing.

551
00:57:56,680 --> 00:57:59,770
The construction of the hexagon using this router and.

552
00:58:16,950 --> 00:58:22,790
Yeah. I think I ask you first, I am for Corey.

553
00:58:22,790 --> 00:58:34,430
I believe in Babylon as you create another piece, which I please come home to say about the corner of your voice.

554
00:58:35,660 --> 00:58:39,830
But I would have created a piece of theatre with another actress from this site.

555
00:58:40,340 --> 00:58:48,249
And we're staging a play groups and one which I took this book as a short story as its inspiration.

556
00:58:48,250 --> 00:58:53,900
But we sort of take it somewhere else that's going to go on in the science museum, from the temple type of thing.

557
00:58:54,800 --> 00:58:57,990
That's all that can be easily accessible.

558
00:58:59,180 --> 00:59:03,740
And I think it was doing that piece of choreography that I learned about my

559
00:59:04,010 --> 00:59:07,130
fifth and final super mathematician who comes from the world of choreography.

560
00:59:07,400 --> 00:59:11,390
And the choreography really is in some sense, geometry in motion.

561
00:59:12,080 --> 00:59:20,270
And I think that a real common use of all the mathematical ideas and mathematical notation, he created his own notation,

562
00:59:20,270 --> 00:59:26,330
which has a lot of mathematics, to sort of articulate what was happening in a piece of choreography.

563
00:59:26,820 --> 00:59:28,850
He wrote this dance.

564
00:59:28,940 --> 00:59:35,899
It should have a sense of the three dimensional geometry with which the massive set man is inclined to follow, to connect, to connect,

565
00:59:35,900 --> 00:59:42,860
sometimes with the 12 on points to the animals eat or in his movements, travelling, as it were, on an invisible network of paths.

566
00:59:43,160 --> 00:59:49,130
And he used to want to try and make that some that we tends to be a bit like a three man mixing two dimensional,

567
00:59:49,640 --> 00:59:53,570
but nobody wanted the dancers to really feel the space around them.

568
00:59:53,780 --> 00:59:58,009
I would ask the dancers to actually really feel like all their movements must be

569
00:59:58,010 --> 01:00:03,770
at all knees the size of Michael's Adrian or maybe dodecahedron around them.

570
01:00:07,160 --> 01:00:11,090
And they have a connection to the world of mathematics, because I'm showing them also,

571
01:00:11,090 --> 01:00:18,480
and I think all artists have a little bit of maths going on inside them, but I think it works the other way around as well as mathematics,

572
01:00:18,560 --> 01:00:28,760
although the maths I think is really driven by an artistic sensibility, I think that a lot of the things we do,

573
01:00:28,760 --> 01:00:35,690
the choices we make, the structures we like choosing, aren't chosen because they're useful in the real world.

574
01:00:35,690 --> 01:00:43,830
We actually choose them because we find them surprising, useful or something exciting, which I think is the same thing, which is motivating.

575
01:00:44,250 --> 01:00:51,890
So one of the books that really inspired me to become an acquisition was a book by a jihadi who had mathematicians topology.

576
01:00:52,580 --> 01:00:56,149
And this Cambridge mathematician writes about what it's like to be a mathematician.

577
01:00:56,150 --> 01:01:03,770
And I was working on this book about that time when I had this crisis about whether I don't get your dreams or the science.

578
01:01:04,550 --> 01:01:09,050
And I really something that's a bridge between the two because HONY really

579
01:01:09,050 --> 01:01:13,670
describes the mathematical world and creates all these sort of American attention.

580
01:01:13,850 --> 01:01:23,089
Y. Kapadia Okay, so our I'm interested in mathematics only as a creative thought he was writing down on anything applied his subject.

581
01:01:23,090 --> 01:01:28,760
So I think he'd be quite surprised to see the ways that even some of his mathematics he's now used the Internet cryptography.

582
01:01:28,760 --> 01:01:34,879
But you know, I think if I was going to choose a beautiful theorem in my mind and I love this one,

583
01:01:34,880 --> 01:01:45,350
it's one of the and so we sort of choose the element of surprise that we kind of find exciting in a piece of what Fermat proved.

584
01:01:45,360 --> 01:01:55,100
But if you take a prime and finally you divide it by four, has a major one, then you can always write that five numbers to square was added together.

585
01:01:56,480 --> 01:02:01,680
That is a kind of weird I mean, why should a prime member have anything to do with sequence?

586
01:02:02,990 --> 01:02:07,190
And so, for example, 41, you might have like four yet remain one.

587
01:02:07,460 --> 01:02:11,710
So 41 can be written as 12, which is squared plus minus one.

588
01:02:12,560 --> 01:02:18,540
Now all for the primes out there, anything, any bronze or anything, any primes which I remain to one one.

589
01:02:18,680 --> 01:02:27,350
The reason why for our secret one every time you get one Fermat's proof guarantees that you'll always be able to write it is to swim.

590
01:02:27,770 --> 01:02:30,559
Yeah, and I wouldn't say that that's particularly useful.

591
01:02:30,560 --> 01:02:37,700
I've never seen it used in any piece of technology, but for me, this is this is a beautiful gem, you know.

592
01:02:37,760 --> 01:02:42,969
And if you read the proof, there's a magnetic excitement, subjectivity out of you guys in its prime.

593
01:02:42,970 --> 01:02:49,940
And so as to swaying numbers and its moments, it's a bit like reading the story with somebody character turns into somebody you didn't expect,

594
01:02:49,940 --> 01:02:52,940
or a musical theme which can take some patience somewhere else.

595
01:02:53,720 --> 01:02:56,130
For me, I had a pleasure in reading proofs of this.

596
01:02:56,150 --> 01:03:02,480
There are many different proofs and it's a sense of pleasure I think I get when I read a piece of literature or listen to a piece of music,

597
01:03:02,940 --> 01:03:07,940
and suddenly somebody surprised me. I think that's what we're all fighting for.

598
01:03:07,940 --> 01:03:12,980
And a piece of mathematics is a piece of mathematics that I created is less complicated than that.

599
01:03:12,990 --> 01:03:18,230
So what about the idea of is this is a symmetrical object that I found in my own.

600
01:03:19,760 --> 01:03:28,530
But I decided to dismantle all day. Had something to do with solving equations in the curve because it's a very different area as well as symmetry.

601
01:03:28,790 --> 01:03:33,190
It's an area that we still find very mysterious trying to find solutions.

602
01:03:33,200 --> 01:03:42,380
These two guys rather like myself here. But the reason for all this I discovered action and encoded in them questions about solving these equations.

603
01:03:42,860 --> 01:03:48,030
Now, for me, it was a creative act to focus on these things.

604
01:03:48,080 --> 01:03:53,720
I could add a computer just to generate endless symmetrical objects, which you have no interest at all,

605
01:03:53,780 --> 01:03:58,290
just like a library Bible is full of all alone, boring books and everything.

606
01:03:58,290 --> 01:04:03,070
Do that. And all the acts of the creative acts of a writer is to say, You know what?

607
01:04:03,320 --> 01:04:09,680
This is the book you should be reading. This is the one, as you know, this is the choice I'm making out of all these possibilities.

608
01:04:09,980 --> 01:04:13,790
And it's the same thing that this idea of creativity and discovery.

609
01:04:13,940 --> 01:04:17,239
Well, there are all these different mediums in mathematics. We've got to choose, make.

610
01:04:17,240 --> 01:04:22,010
But I make a choice. It's this one I want to tell you about and examine all that.

611
01:04:22,010 --> 01:04:25,660
I'll give it to my fellow mathematicians because I can take you on this incredible journey.

612
01:04:25,700 --> 01:04:31,370
Know, wow, how does it connect with that person that's going around with the quotes?

613
01:04:32,120 --> 01:04:32,690
This is a quote.

614
01:04:32,810 --> 01:04:45,070
So I want you to think this is a quote like an oasis or is it a place by a scientist to create precisely information, useless combinations?

615
01:04:45,380 --> 01:04:51,130
Invention is its own choice. The central foundations do not present themselves in the moment.

616
01:04:51,500 --> 01:04:58,350
And I lot of you think that that's an artist talking about so that their way of working.

617
01:05:00,410 --> 01:05:04,240
Fusion using all these unique seats. Scientists working on their way.

618
01:05:05,920 --> 01:05:11,409
These are not usual. Yes, it's something I would like you to all be putting your hands.

619
01:05:11,410 --> 01:05:19,660
I wasn't sure, because actually the message here is that, you know, how how much similarity are processes?

620
01:05:19,840 --> 01:05:26,050
I mean, it was, in fact, a mathematician, a very famous mathematician, or maybe the inventor kind of gave it away.

621
01:05:26,530 --> 01:05:34,960
But actually, Stravinsky always used to pull back himself as an event that he was inventing his music.

622
01:05:35,540 --> 01:05:44,169
But he was a mathematician. And I think that is very often we make choices which have extraordinary impacts on the technological world,

623
01:05:44,170 --> 01:05:47,050
and so help us describe the physical universe around us.

624
01:05:47,410 --> 01:05:55,670
But I think it's driven mathematics is driven really by the same sort of aesthetic sensibility that drives all the secrets repetitions.

625
01:05:56,460 --> 01:06:22,900
Artists like. Owe you.

626
01:06:23,450 --> 01:06:27,410
Yeah, I know. You want me to ask them why they think golden ratio?

627
01:06:27,480 --> 01:06:36,970
Yeah. Oh, my God. How can I see you guys every time you want to change your mind so that you don't screw up?

628
01:06:39,010 --> 01:06:43,159
And so please remember what you're doing.

629
01:06:43,160 --> 01:07:09,209
This would not do anything for me. Yeah. So I'm kind of intrigued, which, you know, systematically pleasing.

630
01:07:09,210 --> 01:07:13,500
So I go to rectangle rectangles here, ones in the golden ratio of ones.

631
01:07:13,500 --> 01:07:20,630
And so there is you find the first rectangle as you probably glance.

632
01:07:23,240 --> 01:07:29,070
Quite a lot of you gave the golden ratio. Okay, what about the second rectangular selection?

633
01:07:29,150 --> 01:07:38,940
Who likes that? The best? And she says had a 5050 split now and yet more simply doesn't deserve to be.

634
01:07:38,940 --> 01:07:54,280
And that's what I feel. But now it's old John's last piece in Boston.

635
01:07:54,850 --> 01:08:04,350
And I did see you press the Japanese open that you are a very erudite one is one of the really challenging questions so you say please be ready.

636
01:08:04,360 --> 01:08:07,900
That is now more than 80%.

637
01:08:08,830 --> 01:08:16,809
Do we have any questions going around? Yes. If we get more assertive, you can stand up when you ask a question that I don't want.

638
01:08:16,810 --> 01:08:22,040
And that's people like rudeness and little things which are related.

639
01:08:22,060 --> 01:08:27,790
I research the poll numbers and on the other hand is that people prefer the golden rectangle,

640
01:08:27,790 --> 01:08:30,760
which is the least high school, which is a real contradiction.

641
01:08:32,210 --> 01:08:40,510
And actually, I've never seen any research that confirms that people do prefer the golden ratio decisively, actually the field.

642
01:08:40,620 --> 01:08:51,290
And he also mentioned some of these music many people find on this album, and it's the composer whose buildings many people find unliveable.

643
01:08:52,370 --> 01:08:58,810
Now, perhaps there's not enough just by mathematics, and some mathematics can be quite strong.

644
01:08:59,240 --> 01:09:05,650
We see. And so I love useful mathematics and I that's where the universe is.

645
01:09:05,950 --> 01:09:12,459
And I think that's that beautiful. You says it's very jolly.

646
01:09:12,460 --> 01:09:19,870
Yes. I mean, I think it is interesting that this kind of attention, because you're absolutely right,

647
01:09:19,870 --> 01:09:23,979
that the gold ratio is an example of an irrational number which cannot be arranged.

648
01:09:23,980 --> 01:09:32,830
Is there the ratio of two to Homer? So it seems to be almost polar opposite ends to those holding on to ratios appliances

649
01:09:32,830 --> 01:09:40,630
using extremely model also like the ratio of ones in the square to doing readings,

650
01:09:41,290 --> 01:09:45,880
partly because when you cut not really hall, you get to see four of the same ratio.

651
01:09:45,940 --> 01:09:49,240
So so I think that's a, you know,

652
01:09:49,450 --> 01:09:55,350
still that golden ratio is in some ways does have a connection cause to hold down the ratios

653
01:09:55,360 --> 01:10:01,540
because the simplest way to generate it is by taking the simplest generating process,

654
01:10:01,540 --> 01:10:03,519
which is to take one, one, two, three,

655
01:10:03,520 --> 01:10:10,660
five and those ratios which very naturally arise from trying to grow something so you find grow out of whole numbers,

656
01:10:10,870 --> 01:10:16,130
you find yourself arriving at that name. It will be so.

657
01:10:16,210 --> 01:10:25,210
So I think that although this is an irrational number, it's still a number which probably had is the original number which is as close to one,

658
01:10:25,390 --> 01:10:32,130
has a measure of that to something which is generated out of whole number ratios of fractions.

659
01:10:32,140 --> 01:10:39,880
So that might be why we're finding both in the world of architecture and both in world of all natural growth.

660
01:10:40,420 --> 01:10:43,840
And that gold ratio does crop up in terms.

661
01:10:43,860 --> 01:10:50,409
And I think that's the what one would say is the reason why we responding to this ratio,

662
01:10:50,410 --> 01:10:55,389
because it's something we're very we're seeing so much around our evolution program

663
01:10:55,390 --> 01:10:58,840
to see it as something natural and and something that we can be at home with.

664
01:10:59,230 --> 01:11:07,750
Interesting gave you come back to Pollock Pollock's fractal paintings he sort of started with some simplicity

665
01:11:07,750 --> 01:11:12,639
then when creating a comparison in interactive and then settled down something that you can measure.

666
01:11:12,640 --> 01:11:15,640
The dimension of these fractals is between one and two,

667
01:11:15,940 --> 01:11:22,239
and what you discover is that the qualities that people find most is that you can please all those

668
01:11:22,240 --> 01:11:26,500
pollocks that have a fractal dimension which is very close to the background you see in nature.

669
01:11:27,070 --> 01:11:35,750
And you know, Pollock data, all of these paintings I went to studio is surrounded by fractal like trees.

670
01:11:35,860 --> 01:11:42,130
And so actually what he's doing is recreating something that we can find we resonate with in the natural world.

671
01:11:42,910 --> 01:11:47,350
Let me go to your second point, which I think is fair, which is, you know,

672
01:11:47,470 --> 01:11:51,600
a lot of these people who are putting mathematics inside their offices are just

673
01:11:51,610 --> 01:11:58,850
producing things which are not very easy to get to grips with when you first hear.

674
01:11:59,320 --> 01:12:01,450
But I think that's true of mathematics as well.

675
01:12:01,720 --> 01:12:09,130
Mathematics requires an investment of time and energy to be able to appreciate the beautiful things in our world.

676
01:12:09,340 --> 01:12:15,549
And it doesn't have to be easy. You know, it's something which is great, shouldn't be just so easily accessible.

677
01:12:15,550 --> 01:12:19,570
And I think that actually, if you listen to it for some time, I mean,

678
01:12:19,570 --> 01:12:24,729
I have the same reaction that I found quite an angry world, but I spent more time in there.

679
01:12:24,730 --> 01:12:30,640
I really came to appreciate and enjoy the complexity of structure that's there.

680
01:12:31,480 --> 01:12:39,880
So I wouldn't necessarily say that just because something first site is not appealing to the masses that we should throw it out.

681
01:12:40,040 --> 01:12:46,120
We did that when we set out with my master's. Lived in the building.

682
01:12:46,960 --> 01:12:50,200
Have you ever. I haven't. No, no. I mean.

683
01:12:50,380 --> 01:12:56,260
But I say I mean, I actually the words counter what you say.

684
01:12:56,530 --> 01:13:03,040
I mean, because I think the resident residence in the city is really enjoying the space.

685
01:13:03,070 --> 01:13:07,260
And I think visually from the outside, it's not perhaps so interesting.

686
01:13:07,870 --> 01:13:09,490
But the inside structure, I think,

687
01:13:10,600 --> 01:13:17,770
is much more appealing than something that might look very similar but doesn't have that incredible mathematical logic to it.

688
01:13:18,940 --> 01:13:28,060
But I think it's great the question marks. More research needs to be done to know how a lot of the duplicate buildings are going after this time.

689
01:13:28,480 --> 01:13:36,250
There's an amazing structure of the chapel, which is kind of a piece of my body geometry that he's made up.

690
01:13:36,650 --> 01:13:42,260
And I find that very. There's a question down here.

691
01:13:42,260 --> 01:13:45,310
We got my hair. And then there's the second question, which just.

692
01:13:48,370 --> 01:13:53,140
So you pass along the facts and you have to stand up to that.

693
01:13:54,700 --> 01:14:06,100
Hello? Another minute. I'm not a mathematician, but I know there's a pattern in when you multiply the number nine,

694
01:14:06,440 --> 01:14:10,770
does the sum of the result always be nine when you add it up?

695
01:14:10,930 --> 01:14:16,270
I was curious if know if it's been applied to me in any way that when.

696
01:14:17,740 --> 01:14:26,970
Well, yes. This is how I apply it to my kids actually, because it is a very useful way when I teach my kids the nine times they will,

697
01:14:26,980 --> 01:14:30,610
you know, it is basically if you want to do so, let me do this search.

698
01:14:30,640 --> 01:14:35,260
You see the ability for design. It has to be 36.

699
01:14:35,710 --> 01:14:39,310
So this is the right easy way. So eight times 972.

700
01:14:39,910 --> 01:14:44,290
And in fact, you know, that's an interesting pattern. And then you say, well, does it always work?

701
01:14:44,830 --> 01:14:49,390
And I think that's the power of mathematics and especially the mathematics of algebra.

702
01:14:50,020 --> 01:15:00,420
The algebra. When I try to explain to people what algebra is, I think it's it's it's finding those kind of the logic behind those patterns in numbers.

703
01:15:00,470 --> 01:15:07,670
You keep on seeing this structure happening. You want to why I was always then you need a world of algebra to represent one discipline every.

704
01:15:08,320 --> 01:15:12,250
I mean another example that I quite like and I'm doing teaching multiplication tables is

705
01:15:12,250 --> 01:15:20,049
my skills is if you take a number and swear it so five times five then and I say five.

706
01:15:20,050 --> 01:15:23,500
And I said, okay, what's more times six? And you go, That's 24.

707
01:15:23,560 --> 01:15:28,990
And then I do. And with another number, the seven nine, 749 six, Sunday 48.

708
01:15:29,390 --> 01:15:36,850
After a while they fall. But what I do is when I take the square and I say the numbers on either side, it's always one less the ones on the sides.

709
01:15:37,060 --> 01:15:40,260
So and that's why I always look at anything.

710
01:15:41,080 --> 01:15:45,490
That's the power of algebra, this language that was introduced by by the Arabs.

711
01:15:45,880 --> 01:15:49,000
And so coming out of the house of wisdom,

712
01:15:49,020 --> 01:15:56,889
electricity and and it's that language which enables you to just sort of work out why that magic always happens.

713
01:15:56,890 --> 01:16:00,880
It will happen, whatever. And it's at the hall to say Fermat's Proof.

714
01:16:01,810 --> 01:16:08,770
It's an algebraic relationship between numbers, which eventually gives the heads of why primes on Division Boys,

715
01:16:08,770 --> 01:16:13,330
for which the remainder one might be pulled apart, makes way swings.

716
01:16:16,250 --> 01:16:26,150
Yes, ma'am. I just wondered whether everyone's choice of reptiles might be influenced by just flat screen televisions,

717
01:16:28,820 --> 01:16:33,740
because, you know, most of these are like the wide format.

718
01:16:33,750 --> 01:16:44,389
And, you know, I'm Paisley that I just never up in there looking for my first musical panoramic and you presented

719
01:16:44,390 --> 01:16:53,720
something new looking and of course there are artists who like wide rectangles like Ivan comes to mind.

720
01:16:54,010 --> 01:17:05,210
I'm just wondering whether you knew anything about the way people design due diligence and the proportions and mathematics of the brain.

721
01:17:05,560 --> 01:17:07,639
I mean, I don't know.

722
01:17:07,640 --> 01:17:16,640
But I'm sure that as you compete with was probably the film would say, well, there are all these choices of what the proportions that you all work in.

723
01:17:16,640 --> 01:17:21,379
And if you're watching a film on your laptop, you know, you see I have more, you know,

724
01:17:21,380 --> 01:17:28,520
baseline we can see as a solution and there will be decisions about what I want, why those ratios are good choices.

725
01:17:28,700 --> 01:17:38,060
And again, are what we enjoy looking at as a screen is probably I mean, you, it's probably the other way around.

726
01:17:38,150 --> 01:17:44,940
Those choices were probably made by you by showing the load of screens and everyone saying, well, I like that one and and you don't move.

727
01:17:45,230 --> 01:17:51,650
Most of the canvases, the majority of canvases will be closer to the golden ratio than anything else.

728
01:17:51,890 --> 01:17:56,390
But if, of course, you look at all these long days, it's disrupting those expectations.

729
01:17:56,390 --> 01:18:01,610
And so to have something long and thin actually challenges what your expectations.

730
01:18:01,940 --> 01:18:05,450
But I think there's something very special about that golden ratio,

731
01:18:05,450 --> 01:18:11,839
which something someone might be able to really see because because that actually spirals

732
01:18:11,840 --> 01:18:17,980
that face inside they're actually but the focus of your eye focus is not on the dead centre.

733
01:18:17,990 --> 01:18:25,160
You have to swear you'll be dead centre. They won't be too controlling about that being the place where something dramatic said.

734
01:18:25,610 --> 01:18:31,370
But actually there are four different places where these spirals and often in a Leonardo painting you draw these.

735
01:18:31,880 --> 01:18:36,680
There is something of interest there and it's almost like you're you're drawn to those lines.

736
01:18:36,680 --> 01:18:40,340
He disrupts the the golden ratio of that canvas.

737
01:18:40,970 --> 01:18:45,390
You want to have that that active spiral drawings in that place.

738
01:18:45,390 --> 01:18:52,910
So I think that also is a motivation for why and art is kind of like that particular shape

739
01:18:52,910 --> 01:18:58,850
because he's doing things to the viewer that they're not aware of bringing into place,

740
01:18:59,180 --> 01:19:05,360
which isn't so obvious to. Yes.

741
01:19:05,370 --> 01:19:16,980
And the question here. You send it off.

742
01:19:17,920 --> 01:19:23,450
An Iraqi said that this is very difficult to make mathematics and you talk about it.

743
01:19:23,640 --> 01:19:26,850
He's very famous, for example, and mathematics, I guess.

744
01:19:27,270 --> 01:19:34,170
I just wondered whether you had another examples of authors who also say these ideas.

745
01:19:35,460 --> 01:19:44,460
Well, one of my favourites is actually kind of the 20th century movements in France, George Perec.

746
01:19:45,490 --> 01:19:51,420
I mean, he's very famous for writing this novel. We never saw the letter E anywhere, so.

747
01:19:51,600 --> 01:19:56,760
But actually on his book of the lines is as magic, which is a story of a building.

748
01:19:57,330 --> 01:20:01,170
And actually, he used its mathematical structure for a massive square.

749
01:20:01,830 --> 01:20:14,200
It's a bit like Sudoku, but it's a way of if you take an example of a Latin writer's square, you take the core course and I can call.

750
01:20:14,220 --> 01:20:18,510
So you call Jack Queen King.

751
01:20:18,510 --> 01:20:19,920
I saw each scene.

752
01:20:20,580 --> 01:20:31,520
The challenge is to arrange in a full line all grades such that no line has the same seats and no line has the same call card in it as well.

753
01:20:31,530 --> 01:20:33,719
And same thing you can do that.

754
01:20:33,720 --> 01:20:44,550
It is a Latin slang for my four pack uses a ten by ten, which is really difficult to construct in the construction of that whole.

755
01:20:44,580 --> 01:20:47,819
So there are a few there are 99 chapters.

756
01:20:47,820 --> 01:20:58,320
So this is one angles very deliberately, but each of those represents a room in his building and he has a set of cool cars and suits.

757
01:20:58,320 --> 01:21:01,709
He has different kind of ideas on all things or something,

758
01:21:01,710 --> 01:21:07,830
and he will try to place these in each of the each of the rooms, in particular control like this Nazi breakfast lamp.

759
01:21:08,520 --> 01:21:12,930
And again, it's this kind of idea of, okay, what happens if I put that constraint on?

760
01:21:13,230 --> 01:21:15,900
I'll get pushed somewhere, which I just let myself.

761
01:21:16,110 --> 01:21:25,230
Okay, let's write a story about an apartment block with 99 rooms and that's too much you and it comes out on your see,

762
01:21:25,340 --> 01:21:31,530
it's actually quite interesting to be pushed somewhere by the constraints of a set of lights.

763
01:21:31,980 --> 01:21:36,260
And I think that's often like why does anyone she's right but what poetry,

764
01:21:36,390 --> 01:21:44,520
you know quality is about the the music of the words but actually also was fun I think in poetry is when you put those constraints,

765
01:21:44,790 --> 01:21:52,770
it sort of forces you to find kind of interesting ways to say things because of the the rhyme structure of the rhythm structure.

766
01:21:53,070 --> 01:22:00,090
And I mean, for example, Shakespeare, you can find the most kind of mathematical mind is something that forces in my head.

767
01:22:00,140 --> 01:22:06,330
I think this is page, but there's a lot of interesting use of numbers in that prime numbers as well,

768
01:22:06,330 --> 01:22:10,260
which is I don't think it's very clear whether anybody.

769
01:22:10,320 --> 01:22:21,710
Simon Chase It was really deliberate, but it's so so I think there are there are see a lot more examples being released.

770
01:22:22,060 --> 01:22:28,450
I mean, there's a nice novel that many of you may have read I saw on the beach and

771
01:22:28,470 --> 01:22:36,330
one of the kids goes off to islands in the forest and tests all the winners.

772
01:22:36,600 --> 01:22:42,210
But he also wrote his second book is called The Tesseract. And it's a very interesting story, I think, set in Manilla.

773
01:22:42,840 --> 01:22:48,930
And the idea that all you get the perspective that a tesseract is that unwraps for dimension.

774
01:22:48,930 --> 01:22:52,410
Q So the idea is that the novel is kind of four dimensional.

775
01:22:52,500 --> 01:22:59,680
You never see that you can never get a full position when you see the whole story.

776
01:22:59,710 --> 01:23:02,880
So you just get these perspectives from different characters.

777
01:23:02,880 --> 01:23:09,010
And it's almost like you're taking this shadow, this shadow, this shadow, and it captured in the back of his mind.

778
01:23:09,010 --> 01:23:13,620
It's quite grey, something where you, you never quite completely know what's going on.

779
01:23:13,620 --> 01:23:20,879
Each character has this difference and I think that sort of ideas are in place until you find the frames.

780
01:23:20,880 --> 01:23:24,930
Copenhagen that's an exercise in quantum physics.

781
01:23:24,930 --> 01:23:29,399
And he runs this meeting between Heisenberg and Born Again and again.

782
01:23:29,400 --> 01:23:33,180
Each time he does it, you observe the experiment, it starts something different.

783
01:23:33,720 --> 01:23:38,280
So it's almost like that the quantum physics is embedded in the structure of the play.

784
01:23:40,050 --> 01:23:43,650
I will go on this some of the question here.

785
01:23:51,910 --> 01:23:57,400
And you mentioned the difficulty in having to choose between since I was at school.

786
01:23:58,030 --> 01:24:05,020
Do you think there'd be any value in a different approach towards the boundaries between art and science in any education?

787
01:24:07,060 --> 01:24:18,160
Absolutely. I think we can suffer from this compartmentalisation of education as students go from school,

788
01:24:18,160 --> 01:24:26,260
from the history lesson to the music to the math and science lesson, and they don't realise that connection between these things.

789
01:24:26,530 --> 01:24:33,010
And actually, I think a lot of people just I have into mathematics just because I researched research.

790
01:24:33,130 --> 01:24:38,500
But if you find a different way and I mean I did this program for the BBC about the history of mathematics.

791
01:24:38,680 --> 01:24:44,860
Now, history is a wonderful way in to do something, to show that mathematics is created by people.

792
01:24:44,860 --> 01:24:52,660
It's connected to particular times in history, cultural changes, for example, imaginary numbers, squared minus one,

793
01:24:53,170 --> 01:24:59,890
quite a little time that it's actually the moment you got to accept it was ties in real closely to the French Revolution.

794
01:25:00,160 --> 01:25:10,780
It's that suddenly accepting new ideas, new changes might be very relevant to that change in the acceptance of something so dramatically challenging.

795
01:25:11,110 --> 01:25:19,440
So I would love it if we created a, you know, a school or a curriculum which, which didn't put subjects in these sort of goals.

796
01:25:19,450 --> 01:25:29,260
I think even I think Oxford is a very interesting example of trying to break down these factors because here we are in mathematics department.

797
01:25:29,290 --> 01:25:35,080
Yeah, this is mathematics gets on there. But actually we all have connections with college here at university.

798
01:25:35,290 --> 01:25:43,150
And in that college I spend all my time talking to people from, well, history, philosophy, economics, literature.

799
01:25:43,450 --> 01:25:50,950
And it's it's that's the I've often found most stimulating is that time when both when I was an undergraduate here,

800
01:25:51,910 --> 01:26:01,240
all my friends were doing kind of deconstructing and anxieties and I had to sort of put my body in that context.

801
01:26:01,270 --> 01:26:07,040
And I think it's important subjects sometimes in isolation, we need to push it through.

802
01:26:08,530 --> 01:26:11,800
But also don't forget to put it into a context as well.

803
01:26:12,100 --> 01:26:19,970
And we can do that right as. Question here, and then we'll have a question back there.

804
01:26:21,470 --> 01:26:26,370
Hi. You stand up? Yeah.

805
01:26:26,810 --> 01:26:33,709
I have two questions. Firstly, I think a member of the assembly,

806
01:26:33,710 --> 01:26:39,680
one of them was allowed to make submissions to the the Hayward's call alternative going through this

807
01:26:39,680 --> 01:26:48,290
under the United States and is being taken by these huge mathematical grids there in the first of that.

808
01:26:48,650 --> 01:26:53,240
And I was like, really? Then I know this was based on an scientists.

809
01:26:53,240 --> 01:27:01,250
And so that really might be because of the mental difficulties and issues of connection between studying maths too intensely and going crazy.

810
01:27:02,380 --> 01:27:13,430
But this is my first and the second one was talking about music to show me that I was one of an experimental music.

811
01:27:13,730 --> 01:27:20,330
And then coming some of ABC about how why is it only certain music seems to include the

812
01:27:20,330 --> 01:27:27,530
feeling of anxiety and kind of you know is not easy to listen to and is it possible to

813
01:27:27,530 --> 01:27:32,450
create mathematical randomised music that's actually nice to listen to and what are the

814
01:27:32,450 --> 01:27:39,410
constraints you have on the mathematical models in order to make them pleasant harmonics?

815
01:27:40,130 --> 01:27:46,910
And so that I also went to this exhibition and it was a very interesting example.

816
01:27:47,120 --> 01:27:57,580
I mean that those early grades were actually examples of the last records when he was an artist performing there and the things

817
01:27:57,590 --> 01:28:04,249
that I think they found their way like a calendar and it had residencies with Mayan calendars as a kind of Mayan thing.

818
01:28:04,250 --> 01:28:06,260
To the question,

819
01:28:06,260 --> 01:28:16,520
I think one has to be very careful about this connection between mental health and and doing something like art or mathematics to an extreme.

820
01:28:17,330 --> 01:28:27,379
It's very easy to pick out examples in my panel of people who have been institutionalised because of mental health issues.

821
01:28:27,380 --> 01:28:34,100
And I think one has to be very careful about saying, oh, it's because they push their brains to the extreme.

822
01:28:34,810 --> 01:28:38,920
When you think about cancel who decided to fantasy,

823
01:28:38,990 --> 01:28:43,850
he spent quite a lot of time in a mental health institution and how but you know that he

824
01:28:43,850 --> 01:28:48,319
would have had that mental health issue regardless of whether he was doing the mathematics.

825
01:28:48,320 --> 01:28:52,850
That has to be clear. And I think Nash, for example, beautiful minds.

826
01:28:54,590 --> 01:28:59,510
I think I think it is he spent so much time in a very abstract start.

827
01:28:59,510 --> 01:29:05,770
Well, we know connection to people. Does that accentuates that mental health issue that he might have already?

828
01:29:05,780 --> 01:29:09,019
And I think that's an interesting one to explore.

829
01:29:09,020 --> 01:29:19,100
But I think I find people who just too easily can say the mental health and being is a helpful, connected.

830
01:29:20,030 --> 01:29:26,900
And so I think it's a complicated issue which probably deserves more work.

831
01:29:27,140 --> 01:29:31,890
Now, what's the second question, which is music as well?

832
01:29:31,910 --> 01:29:36,440
And, you know, I think that saying yes, I mean, it's already been a challenge about,

833
01:29:36,800 --> 01:29:41,150
you know, all of this music which has had a disruption, seems can't listen to.

834
01:29:41,450 --> 01:29:48,710
But actually if you go back to the music of golf, which basically out of is one of the most listenable pieces of music,

835
01:29:49,220 --> 01:29:57,530
someone something like that old band Variations does have an old mathematical structure, and ideas of symmetry are things that we're responding to.

836
01:29:57,580 --> 01:30:01,850
We like we like to start saying something goes up and then we hear the same thing.

837
01:30:01,930 --> 01:30:05,000
That's the reason upside down.

838
01:30:05,450 --> 01:30:07,880
We respond to a connection between those two things.

839
01:30:08,180 --> 01:30:19,069
And a friend of mine, actually, Pachelbel's Canon, is one of these tunes everyone seems to love and brings in as well.

840
01:30:19,070 --> 01:30:29,660
Actually, he was able to to write a computer program when she was able to tweet 140 characters reproduced below ten,

841
01:30:29,730 --> 01:30:34,340
and the structure is all it is in just 140 characters in the computer.

842
01:30:35,270 --> 01:30:42,860
So one could say All your longing to listen to what's happening is that generative structure is purely mathematical.

843
01:30:42,860 --> 01:30:51,500
So. So I think, I think recently in a show at the Royal Opera House, I'll be exploring the mathematics of the Magic Flute.

844
01:30:51,950 --> 01:31:01,280
Now, many people love magic, so what they don't know is how much mathematics Mozart was using in order to write music.

845
01:31:02,330 --> 01:31:06,590
He just become a mason seven years earlier, and he learned about things like the old section.

846
01:31:06,860 --> 01:31:10,520
And if you look at the overture, the overture is structured and such.

847
01:31:10,550 --> 01:31:18,940
The key man with a triple chord happens. And as his transformation is, you have 83 bars and 103 bars is the perfect choice.

848
01:31:18,980 --> 01:31:23,290
If you alter a. You're shifting all that old ratio.

849
01:31:23,290 --> 01:31:27,970
There's this sort of moments that it's based on. I think M.J. is deliberately.

850
01:31:28,540 --> 01:31:30,620
Well, I mean, he's doing this, supposedly,

851
01:31:30,670 --> 01:31:37,170
but I think because he spent time with the Masons he knew about the gold rush is very important to a lot of the science symbolism.

852
01:31:38,620 --> 01:31:43,500
So I think I would counter that even the music that we find very listen to.

853
01:31:44,200 --> 01:31:49,280
I think it's possible to find a lot of mathematics, which is which is high minded.

854
01:31:51,620 --> 01:31:55,030
Got it. How you doing this time? You to one more question.

855
01:31:56,050 --> 01:31:58,960
Yeah. We had a question about the breakfast.

856
01:31:59,980 --> 01:32:05,440
I was just wondering on the front line, I was wondering if you thought of the background being in the movie,

857
01:32:05,440 --> 01:32:09,640
the whole movie newest thing, or if it has anything to do with evolution.

858
01:32:11,930 --> 01:32:21,430
Okay. So my oldest would of course, the painting does have the symbol that Pentagram, that's the the symbol used by Masons.

859
01:32:21,430 --> 01:32:27,260
And the reason they use it is also because the devil worshipping it, because hidden inside there is the golden ratio.

860
01:32:27,280 --> 01:32:34,540
If you look at it, it's all over the place and you look at the long length across the top, one point to the other,

861
01:32:34,720 --> 01:32:45,810
and then compare that to the points going all the way to the sort of the angle of the side that is in the golden ratio establishment ratio.

862
01:32:46,060 --> 01:32:51,170
So it's a sort of like a template, but it depends around the temple is a way for an architect.

863
01:32:51,190 --> 01:33:00,610
What am I doing? So, so in mind here is actually creating things with aesthetic and using if you guys in Psychology

864
01:33:00,610 --> 01:33:08,920
London which is next to the Royal Palace outside on the pavements is a pentagram being changed?

865
01:33:09,340 --> 01:33:14,200
Now these backgrounds and the background is an image of the Alhambra.

866
01:33:14,500 --> 01:33:24,110
Alhambra is an example of a combination of art, science and this idea of infinity thing.

867
01:33:24,130 --> 01:33:33,610
One of the reasons them the more advanced is these Islamic artists enjoys playing around with the symmetry and tilings like this.

868
01:33:33,610 --> 01:33:44,110
Is that in a finite wall you can express the sense of Venice because that symmetry tells you exactly what to do.

869
01:33:44,260 --> 01:33:45,579
However, you go on in this,

870
01:33:45,580 --> 01:33:57,220
you see sort of it's sort of like capturing one of the ideas that so obviously captured their idea of gold in some way, things like that.

871
01:33:57,370 --> 01:34:04,530
And that's sometimes why they actually would a little imperfection because they would have nervous of trying to pretend to be gold.

872
01:34:04,550 --> 01:34:09,940
And so they were using this imagery. An Arabic comic, for example, would often have a little arrow there.

873
01:34:10,090 --> 01:34:16,360
So they won't say that I'm I'm on gold creating something that is imperfection.

874
01:34:19,600 --> 01:34:24,250
Well, no, I don't think so. Thank you very much for being a great audience.

875
01:34:37,730 --> 01:34:49,080
After starting a policy seeing country outside of Kosovo and whether or not this is going to be.
