In modern mathematics, many of the biggest advances are great elaborations of theory. Mathematicians move mountains, but their strength comes from tools, highly sophisticated abstractions that can act like a robotic glove, enhancing the wearer's strength. John Conway was a throwback, a natural problem-solver whose unassisted feats often left his colleagues stunned.

"Every top mathematician was in awe of his strength. People said he was the only mathematician who could do things with his own bare hands," said Stephen Miller, a mathematician at Rutgers University.

Princeton mathematician John Conway has died of the coronavirus. He was 82 years old. The British-born Conway spent the early part of his career at Cambridge before moving to Princeton University in the 1980s. He made contributions in various areas of mathematics but is best known for his invention of Conway's Game of Life, a cellular automaton in which simple rules give rise to surprisingly complex behaviors. It was made famous by a 1970 Scientific American article and has had a lively community around it ever since then.
