THE RECORD
What changed
Newton developed three laws of motion and inverse-square gravity, applying them to Kepler's laws, tides and comets.
EVIDENCE
What remains
Editions, manuscripts, correspondence, observations and later calculations document development and testing.
WHY IT MATTERS
Why it matters
It established a powerful framework for predicting nature through universal mathematical laws.
OPEN QUESTION
Where interpretation begins
It was not Newton's isolated revolution; it built on Galileo, Kepler, Huygens, Hooke and many observers.
