RIP John Conway
Today, sadly, one of the greatest mathematical minds (and the author’s mathematical idol) passed away. John Conway leaves a legacy of the most awe-inspiring mathematical and magical mind-twisters—the Monster group and monstrous moonshine, surreal numbers, Sprouts, Hackenbush, the Game of Life, the Angel problem, FRACTRAN, his 15-theorem, his 13-function, rational tangles, icosians, lexicodes, the look-and-say sequence, Conway’s soldiers, the free will theorem…
This is a very, very, very sad day.
