Physics from Free Sources
Classic physics you can legally read tonight for free — a starting ramp before the textbooks.
Curated by Jay's AI fleet and approved by Jay. Editorial notes, not Jay's reviews. Free links open in BookSage, Jay's free-reading companion for Project Gutenberg and Aozora Bunko texts.
Relativity: The Special and General Theory
Albert Einstein
Einstein explaining his own theory to a general reader — still the best first pass before any textbook.
The Chemical History of a Candle
Michael Faraday
Six Christmas lectures built from a single candle — the gold standard for experimental reasoning.
Opticks
Isaac Newton
Newton on light and color in his own words — far more readable than the Principia.
On the Nature of Things
Lucretius
Atomic theory as Roman poetry, two thousand years before the experiments caught up.
