Or maybe we could get some insights on where it all came from. I'm not going to prove it in this video. That's a little bit beyond our scope. Although I do want to do it. And there's actually some really neat mathematics that might show up in, if you're a math lead, there's something called Stirling's formula, which you might want to do a Wikipedia search on, which is really fascinating. It approximates factorials with essentially a continuous function, but I won't go into that right now. But the normal distribution is 1 over, this is how it's normally written, the standard deviation times the square root of 2 pi times e to the minus 1 half.
