00:00:00.000 --> 00:00:02.325
Yesterday was March 14.

2
00:00:02.825 --> 00:00:06.645
We celebrated Pi day. March 14. 3, 14.

3
00:00:06.995 --> 00:00:08.725
It's like the first digits of Pi,

4
00:00:08.935 --> 00:00:13.365
3.1 4 1 5 9 2 6 5 3, and so on and so on.

5
00:00:13.785 --> 00:00:16.125
So I want to show you something crazy about Pi tonight,

6
00:00:16.425 --> 00:00:17.725
but for this I need some help.

7
00:00:17.985 --> 00:00:19.045
Can you join me on stage please?

8
00:00:19.105 --> 00:00:21.005
Big round of applause for her. And what is your name?

9
00:00:21.365 --> 00:00:24.045
Mikaella. Mikaella? Yes. Vincent, nice to meet you.

10
00:00:24.225 --> 00:00:26.245
Are you good with science? No.

11
00:00:26.425 --> 00:00:28.925
You know Pi though, you learned this at school? Yes. Yes.

12
00:00:29.155 --> 00:00:31.565
Some people know that Pi is infinite.

13
00:00:31.635 --> 00:00:35.205
Some crazy people try to memorize as many digits

14
00:00:35.205 --> 00:00:36.245
of Pi as they can.

15
00:00:36.425 --> 00:00:39.325
If you want to buy a book to fill your lonely nights,

16
00:00:39.705 --> 00:00:41.005
you can find a book like this

17
00:00:41.075 --> 00:00:43.245
that lists all the decimals of Pi.

18
00:00:43.605 --> 00:00:46.205
I have no social life, so I learned that book.

19
00:00:46.345 --> 00:00:47.645
So Mikaella, I give you the book.

20
00:00:47.755 --> 00:00:49.405
When I look away, can I ask you to go

21
00:00:49.405 --> 00:00:51.045
to any page you want the page you have?

22
00:00:51.045 --> 00:00:54.005
You have numbers everywhere on the page, correct? Yes. Okay.

23
00:00:54.185 --> 00:00:56.965
Now on that page, there is also a page number.

24
00:00:57.145 --> 00:00:58.525
You wanna tell me the page number?

25
00:00:58.925 --> 00:01:03.285
I will try to remember the beginning of that. Page 25. 25.

26
00:01:03.625 --> 00:01:08.565
So if I remember correctly, page 25 starts with a three.

27
00:01:08.665 --> 00:01:12.365
Is this correct? Yes. Yes. It's followed by a one? Yes.

28
00:01:12.505 --> 00:01:15.645
And another one? Yes. And then it's an eight? Yes.

29
00:01:15.785 --> 00:01:17.525
Is this correct? Yes. Okay, perfect.

30
00:01:17.865 --> 00:01:19.565
Now, this is very easy to do

31
00:01:19.565 --> 00:01:21.045
because Mikaella, I can look at you.

32
00:01:21.045 --> 00:01:23.325
Now again, if I ask you to recite the alphabet,

33
00:01:23.505 --> 00:01:25.805
you would go A, B, C, D and so on and so on.

34
00:01:25.805 --> 00:01:27.685
You start at the beginning. That's what I did.

35
00:01:27.765 --> 00:01:29.165
I start at the beginning of the page.

36
00:01:29.625 --> 00:01:30.565
But if I ask you

37
00:01:31.445 --> 00:01:36.325
N-O-P-Q-R. N-O-P-Q-R, then you realize

38
00:01:36.325 --> 00:01:38.645
that N-O-P-Q-R is a sequence

39
00:01:38.645 --> 00:01:40.285
of five letters in the alphabet.

40
00:01:40.475 --> 00:01:42.005
Because you know your alphabet,

41
00:01:42.005 --> 00:01:44.885
you can find these five letters and then you can keep going.

42
00:01:45.245 --> 00:01:46.525
S-T-U-V-W and so on.

43
00:01:46.745 --> 00:01:48.245
That's exactly what we're going to do

44
00:01:48.395 --> 00:01:50.685
with the 17,000 digits I have in my head.

45
00:01:51.105 --> 00:01:52.885
So I'm gonna ask you to go to any page you want.

46
00:01:53.105 --> 00:01:55.525
Now on that page, you have numbers everywhere. Yes.

47
00:01:55.745 --> 00:01:58.205
Go to any line you want on that line.

48
00:01:58.305 --> 00:01:59.765
Go to any number you want.

49
00:01:59.905 --> 00:02:02.445
You're gonna tell me that number and the next, and the next.

50
00:02:02.445 --> 00:02:03.525
And the next, just a few.

51
00:02:03.625 --> 00:02:06.125
And I will try to remember where you are in the sequence

52
00:02:06.125 --> 00:02:07.205
of 10,000 digits.

53
00:02:07.205 --> 00:02:11.405
Okay? What's your number? Four. Four. After that?

54
00:02:12.785 --> 00:02:17.365
Two. Two. After that one. Okay. Is it a six after? Yes.

55
00:02:17.515 --> 00:02:21.445
Okay. Is it a seven after? Yes. A double nine? Yes.

56
00:02:21.585 --> 00:02:23.925
And then it's a one and a three and a one. Yes.

57
00:02:24.115 --> 00:02:26.485
It's followed by eight again. Yes. Yes.

58
00:02:26.545 --> 00:02:29.965
And then it's a three and a five and a zero and a one

59
00:02:29.985 --> 00:02:32.405
and a six and a seven and a three and a two and a nine

60
00:02:32.405 --> 00:02:33.565
and a three and a one and a one.

61
00:02:33.565 --> 00:02:34.765
And and an eight, sorry.

62
00:02:34.865 --> 00:02:36.925
And then it's a five and a two and a zero and a two

63
00:02:36.925 --> 00:02:38.885
and a six and a three and a three and a four and a nine

64
00:02:38.885 --> 00:02:40.365
and a three and a one and a one and a eight

65
00:02:40.365 --> 00:02:41.525
and a six and a five and a zero.

66
00:02:41.525 --> 00:02:43.085
And a two and a seven. And I

67
00:02:43.085 --> 00:02:44.205
can't breathe anymore, but I think that's okay.

68
00:02:44.225 --> 00:02:48.205
All good. Perfect. Thank you. All good?

69
00:02:48.225 --> 00:02:49.645
Really cool. Cool, cool.

70
00:02:49.875 --> 00:02:51.805
Okay, so there is something else crazy about

71
00:02:51.955 --> 00:02:53.205
Pi because it's infinite.

72
00:02:53.345 --> 00:02:56.365
People say you can find anything in Pi, maybe.

73
00:02:56.465 --> 00:02:58.445
Uh, you can find your credit card number.

74
00:02:58.825 --> 00:03:00.165
Uh, you can. Don't worry,

75
00:03:00.165 --> 00:03:01.565
your credit card number is somewhere

76
00:03:01.565 --> 00:03:02.605
in Pi, but we don't know where.

77
00:03:02.985 --> 00:03:05.525
Uh, let's do something less dangerous. Maybe your birthday.

78
00:03:05.625 --> 00:03:09.085
What's your month? September. September. So that's 0 9.

79
00:03:09.385 --> 00:03:14.045
What's your day? Four. Four. So 0 9 0 4. Yes.

80
00:03:14.045 --> 00:03:17.765
Somewhere in the infinity of Pi. There is 0 9 0 4.

81
00:03:18.265 --> 00:03:20.125
Now I'm hoping you are in the book.

82
00:03:20.905 --> 00:03:24.285
If you are in the book, I will try to find the exact page

83
00:03:24.375 --> 00:03:25.525
where we can find you.

84
00:03:25.865 --> 00:03:28.325
And then the line. And then the position on the line.

85
00:03:28.665 --> 00:03:30.685
The first question is, are you in the book?

86
00:03:31.165 --> 00:03:32.645
I mean, the first question is, am I crazy?

87
00:03:32.705 --> 00:03:36.285
But the second question is, are you in the book? 0 9 0 4.

88
00:03:36.745 --> 00:03:40.045
0 9 0 4. I think she's on page 50.

89
00:03:41.365 --> 00:03:42.965
I wanna say 54.

90
00:03:45.625 --> 00:03:48.085
Go to page 54. Oh, that's after the bookmark.

91
00:03:48.085 --> 00:03:51.045
That's why I was struggling. And then you go on line 18.

92
00:03:51.785 --> 00:03:53.725
Can you see your birthday? Somewhere on that line.

93
00:03:54.085 --> 00:03:56.765
I want to say on position 12 on line 18.

94
00:03:57.225 --> 00:04:02.225
1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18.

95
00:04:04.225 --> 00:04:08.645
And if we go for 0 9 0 4, yeah, exactly. Yes. Perfect.

96
00:04:08.645 --> 00:04:09.885
Thank you. Big round of applause for her.

97
00:04:12.045 --> 00:04:13.885
I have to keep the book. But thank

98
00:04:13.885 --> 00:04:14.965
you for your help with Infinity.

99
00:04:14.965 --> 00:04:16.845
Big round applause for Mikaella. Thank you very much.

100
00:04:17.695 --> 00:04:19.965
Enjoy the rest of the evening. Thank you very much. Bye.
