## TL;DR

Renaissance science (15th-17th centuries) broke from Aristotelian/medieval frameworks. Key figures: Leonardo da Vinci (anatomy, engineering), Copernicus (heliocentric cosmology), Vesalius (modern anatomy, De Humani Corporis Fabrica, 1543), Galileo (experimental physics, telescopic astronomy). The printing press spread knowledge faster than ever before.

## Core Explanation

Vesalius (1543): corrected Galen's errors (dissected human bodies, not animals). Galileo: leaning tower experiment (apocryphal but illustrative), inertia concept, telescope discoveries (Jupiter moons, Venus phases, sunspots) — all supported Copernicus. Paracelsus: chemical medicine over humors. William Gilbert: magnetism (De Magnete, 1600). Renaissance humanism emphasized observation over authority.
