Time-lapse of a single cell transforming into a salamander (2019)

I haven't. I think people are too afraid to say "I don't know".

But man, our universe sure is weird. On a fundamental level. I think people under-model just how strange our universe is. Even things like Pi. Why does Pi equal Pi? What an unlikely number to define something fundamental about the universe itself. Or take the logistic map [0]. I mean, what? Why is our universe this way? Or Euler's Identity (e^(pi*i) = -1). Why e? Why pi? I get that the math works, why does the universe need those values for the math to work?

Pi is just the ratio between the diameter and all the points to the same distance from another point, in base 10.

As simple as it gets. Circle = infinite points, thus Pi = infinite decimals.

There's no magic.

Does pi (math) exist at all is perhaps the more interesting question. Or that why can seemingly ‘random’ rules we made up be applied to the real world. Especially when it comes to infinity.

Well, it has to be equal to something, right?
