Something wrong?The mathematician who sketched the blueprint for the digital age - and for mutual assured destruction. Von Neumann built the architecture of the modern computer, laid the formal groundwork for game theory and quantum mechanics, then turned that mind to ICBMs and the hydrogen bomb.

The sciences do not try to explain, they hardly even try to interpret, they mainly make models.
The total subject of mathematics is clearly too broad for any one of us.
For progress there is no cure.... The only safety possible is relative, and it lies in an intelligent exercise of day-to-day judgement.

Born in Budapest in 1903, János Neumann was already rewriting the foundations of mathematics and quantum physics by his twenties. He arrived in America and kept going: cellular automata, self-replicating systems, the stored-program computer. During World War II he developed the explosive-lens math that made implosion weapons possible, then spent the 1950s at the peak of Cold War influence - chairing missile committees, sitting on the Atomic Energy Commission, designing the country's first ICBM programs as the Defense Department's leading nuclear strategist. He died in 1957 at fifty-three, leaving a crater on the Moon and the bones of half a dozen sciences.
