Roots: how the world was first measured and numbered

est 26h · logged 0h · started · touched

The foundations the standard story skips — on both sides. The non-Western roots: Babylonian place-value and astronomy, Egyptian geometry, India's zero and infinite series, China's empirical science and negative numbers, and the Islamic Golden Age that carried algebra, the algorithm, and the experimental method into the world. And the Greek roots this app's first draft wrongly dropped: Euclid's proof as the grammar of physics, Archimedes' statics and hydrostatics, the atomists, and Aristotle as the paradigm later overturned. By 1500 the ingredients Galileo inherited were in place — a synthesis of many traditions, not a European invention from nothing, and not a story with the Greeks written out of it either. Read critically: some transmission claims (Kerala calculus reaching Europe) are unproven, Lloyd's survey is sound but dated (1970), and Russo's Forgotten Revolution makes a genuinely contested case for how far Hellenistic science reached.
