John von Neumann: The Mathematician Who Abstracted Everything
A Man from the Future: Why Johnny Can't Stop Abstracting
In his 53 years, John von Neumann seeded set theory, quantum mechanics, game theory, the stored-program computer, and more. This essay traces his superpower: the art of abstraction—replacing a messy object with the smallest structure that behaves the same way. From redefining ordinals as sets to axiomatizing expected utility in an afternoon, he kept arriving, finding the minimal axioms, and leaving before the theorems fell out.
Every time there was an important discovery in physics, mathematics or computation, John von Neumann was there.
