Central Limit Theorem
A nice illustration of the Central Limit Theorem by convolution.
Heaviside 0,1,0) }
What I really like about this dimostrazione is that it’s not a proof, rather an experiment carried out on a computer.
This empiricism is especially cool since the Bell Curve, 80/20 Rule, etc, have become such a religion.
NERD NOTE: Which weapon is better, a 1d10 longsword, or a 2d4 oaken staff? Sometimes the damage is written as 1-10 longsword and 2-8 quarterstaff. However, these ranges disregard the greater likelihood of the quarterstaff scoring 4,5,6 damage than 1,2,7,8. The longsword’s distribution 1d10 ~Uniform[1,10], while 2d4 looks like a Λ.
(To see this another way, think of the combinatorics.)
