Fascinating. I didn’t understand a thing but watched until the end.

In dnd we call this rolling with advantage

"roll a D20 with advantage" "nah, I'll just divide the result by 20, take the square root, and multiply it by 20"

awesome, but computationally speaking, which one is faster?

The part where i stop following is why does P(x <= P^2) equal P^2?

The sqrt of a number less than 1 is always larger than the number, and the max of 2 numbers is always larger than one - but not necessarily by the same amount as the sqrt…?

Great job! The explanation is clear, the Math is correct, the visuals are great. I loved it!

So, is finding the max of n random values more computationally efficient than finding the n-root of one of them?

Is the area outside the square the same as inside?

i always wonder what programs you use to make the visuals is it just animated in after effects with action script or made in an game engine like Unity

I wish Matt Parker was my friend and showed me non-obvious things!

can anyone explain to me what max means? I'm good in math but what does it mean

How ‘bias towards being larger?’🤔

that green square animation was very satisfying. just need to add a zipper sound

when the gibberish starts making sense so you gotta check if you lucid dreaming in your math classroom

I don't know much about computing, but wouldn't this save a lot of resources as the number of variables grows bigger?
