Excellent video. Just one mistake that has to be rectified. At 9'03'', the graph illustrating Kurtorsis is incorrect. Re-scaled Kurtorsis is an indicator of heavy tails compared to normal distributions. In that graph, the light blue curve with heavy tails (e. g. a t distribution PDF) should have a positive Kurtorsis, while the blue curve with thin tails should have a negative Kurtorsis.

I came here because I thought it was going to be about generating random numbers. Does this have anything to do with the difficulty in generating truly random numbers?
Loved the ending.

CORRECTION: At 6: 20 the summation on the left should be divided by N. Also, at 7: 49 we meant (-2)-2 and not -2-2. Thanks a ton guys for helping us spot those issues.

I'm watching this just before my lunch time. Now I want some french fries.
Edit: Yup. Done with the video, it's lunch time - I'm heading to go get fries.
