Exactly and may be "growing in my garden" means he needed sheets and sheets to lay out on the ground for evaluating the expanding formula, lots of papers all with written numbers, sums and digits on them for calculation and approval. Such a genius brain, too bad his garden was just big enough to evaluate Zeta of 3.

You could not have been closer in 87 trials: 87 / 71 - 1.20205 = 0.02330 87 / 72 - 1.20205 = 0.00628 87 / 73 - 1.20205 = -0.01026 To get no error: 1 / (1.202056903 / 87) = 72.3759 expected number of primes.

This is some of the first use of Monte Carlo i've seen in Numberphile which I think has been a real missed opportunity for the channel as MC is such an interesting topic. I think it could make an interesting video to talk about how we can approximate other constants like pi and e or solve integrals etc. using random numbers.

Note that the letter pi in the latter part of the video is an upper-case pi (means product). The pi at the beginning is lower-case (the constant pi). Both of them are discussed in the context of Euler though...
I like how Google reads my mind recommending videos. I have a math clock, and just saw the 1 on the clock (which in my case is apery's constant).

I was just going to say the same thing. He looked at pairs of numbers instead of sets of three, which give an estimate for ζ(2) which Euler shows was equal to π²/6, and so it gives an estimate of π.
Gotta love the one they kept on the screen longest was 69, 420, 9001 XD
Great video
I like his happy little face at 10:09.
On a completely different note, I did find a simpler way of representing the ceiling function with an infinite sum of the sign function (or my version which is x/|x|) and moving it around, it might simplify the collatz conjecture or something
This is essentialy what Matt Parker did on pi day. But it's nice to see how this generalizes to other values of the zeta function
Just ran a little simulation in Mathematica. Turns out asking if three numbers are coprime in Mathematica (CoprimeQ[a,b,c]) is NOT the same as asking if the greatest common divisor of the three is 1 (GCD[a,b,c]==1). In the first case, it checks each pair of numbers to see if they are coprime and returns true only if ALL pairs are coprime. In the second, it simply finds the greatest divisor common to all three. So, CoprimeQ[2, 4, 9] --> False, but GCD[2, 4, 9] ==1. To approximate Apéry's Constant, you have to use GCD.
That's an amazing result!
6:03 - what a Parker square of a reply
This was beautiful math!
Actually, 1.208333 is as accurate as it can be with that sample size. 87/73 = 1.1917808(irr), so 1.20206 sits right between those two values, meaning this was actually exactly perfect. Amazing.
He's like so happy in the end :)

He said in the video that he chose them. He might have had 100 total, and started removing them until he got the desired accuracy. He might have had 80 and started adding only those that would get him closer to the constant. Whatever way it was done, never trust sample sizes that aren't round numbers.

7:50 Wow, that's a lot to do by hand. I'd suggest heading over the CS dept first next time to get a quick script that'll automate it
By using the arithmetic series 1/(1-r) = 1+r+r^2+... with r=1/p^3 and a simple combinatory argument, using the fundamental theorem of arithmetic it is not hard to see that Apéry's constant equals the product over all primes p of (p^3)/(p^3-1). So Apéry's constant is the limit of n to infinity of the ratio a/b where a = prod{i=1 to n} (p[i]^3) and b = prod{i=1 to n} (p[i]^3-1), p[i]= the i-th prime number and a and b are coprime and get arbitrary large. But the sheer fact that we need arbitrary large numbers a and b to express the representation a/b for A is not yet any proof that A itself is irrational. After all 99999999... /100000000... = 1. Didn't expect to solve it, just nice stuff to play with!
