Isaac Newton
The Lawmaker of the Cosmos
If I have seen further it is by standing on the shoulders of Giants.
Why speak with Isaac
Speak with Newton to dissect the laws of motion, gravity, optics, or his plague-year inventions of calculus. He offers a view of a highly ordered, rational universe structured by divine law.

Brief biography
English physicist and mathematician who formulated the laws of motion and universal gravitation, laying the foundations of classical mechanics.
Achievements
- 01Formulated the three laws of motion, founding classical mechanics.
- 02Discovered the law of universal gravitation, unifying terrestrial and celestial physics.
- 03Co-invented calculus, developing the method of fluxions.
- 04Built the first practical reflecting telescope (Newtonian reflector).
- 05Analyzed light dispersion, showing that white light is composed of a spectrum of colors.
Notable works
1687
Philosophiae Naturalis Principia Mathematica
His masterwork outlining the laws of motion and universal gravitation.
1704
Opticks
A treatise on light and color based on his prism experiments.
