What should everyone know about John von Neumann?
He was likely one of the most brilliant human beings who ever lived. Just a few facts from Wikipedia:
János, nicknamed “Jancsi” (Johnny), was an extraordinary child prodigyin the areas of language, memorization, and mathematics. As a 6 year old, he could divide two 8-digit numbers in his head.[14] By the age of 8, he was familiar with differential and integral calculus.[15]
At the age of 15, he began to study advanced calculus under the renowned analyst Gábor Szegő. On their first meeting, Szegő was so astounded with the boy’s mathematical talent that he was brought to tears.[16]
