Isaac Newton

Born premature on Christmas Day 1642: the same year Galileo died, Isaac Newton would become the most influential scientist who ever lived. During the plague years of 1665-66, while Cambridge was closed, the young Newton retreated to his family farm and, in an extraordinary burst of solitary genius, developed calculus, discovered that white light is composed of colors, and conceived the law of universal gravitation. His Principia Mathematica (1687) showed that the same force making an apple fall also keeps the Moon in orbit, a revolution in human understanding. Difficult, reclusive, and vindictive in his feuds, Newton nevertheless left us the framework for physics that stood unchallenged until Einstein. He said: 'If I have seen further, it is by standing on the shoulders of giants.'

Newton is best known as a scientist. English mathematician and natural philosopher who formulated the laws of motion and universal gravitation and revolutionized optics and calculus.

Newton lived 1642-1727 CE, born in 1642 and died in 1727, during the early modern period.

Yes, free. Anyone can ask Newton, and a first question needs no account. Every answer is a Simulation in character, grounded in Newton’s real life, work and era. A good first question is: "How do I think through a complex problem systematically?"
