Fabrice Bellard (en.wikipedia.org)

amazing how young this guy is despite having done so much

In 1997, he discovered a new, faster formula to calculate single digits of pi in hexadecimal representation, known as Bellard's formula. It is a variant of the Bailey–Borwein–Plouffe formula.

at only 25

this is the guy who every nerd thinks they are, when in reality we just watch youtubes and shitpost on forums

Actually use his Tiny C Compiler, which I was surprised to learn still works under Windows 98. (At least the 32bit version.)

I think Fabrice is what is known as 10x engineer. They do exist.

There is not only depth but also breadth in the projects he has created.
