# Issac Newton

### Philosopher, Mathematician, Astronomer, Physicist, Scientist (1643â€“1727)

born in Woolsthorpe, England

In 1687, he published his most acclaimed work, *Philosophiae Naturalis Principia Mathematica* (*Mathematical Principles of Natural Philosophy*), which has been called the single most influential book on physics.

Newton proposed the use of reflecting mirrors rather than refracting lenses. A large mirror would capture the image, then a smaller mirror would bounce it into the viewer's eye. Not only does this method produce a clearer image, it also allows for a much smaller telescope.Grinding the mirrors himself, Newton assembled a prototype and presented it to the Royal Society in 1670. Merely 6 inches long, the device eliminated color refraction and boasted 40x magnification.

The three laws of motion were first compiled by Isaac Newton in his *PhilosophiÃ¦ Naturalis Principia Mathematica* (*Mathematical Principles of Natural Philosophy*), first published in 1687.[4] Newton used them to explain and investigate the motion of many physical objects and systems.

Newton has a lot to do with what we do today as people. He made the laws of motion. He also made the refracting mirror and if he didn't science wouldn't be the same today.
