Russell's paradox
- logic
- european
The set of all sets that are not members of themselves contradicts naive set theory; Frege's system collapses.
From the Ishango bone to formalized proofs: arithmetic, geometry, algebra, analysis, probability, logic and topology across Babylonian, Egyptian, Greek, Indian, Chinese, Islamic and European mathematics and beyond. Moments are tagged by area (and colored by it) and by civilization; eras are shown as spans. Ancient dates are approximate and say so. Summaries are our own; each moment links to its Wikipedia articles.
