**"Newton, Isaac"**A British mathematician and physicist who lived from 1643 - 1727. Newton made major advances in the studies of optics, mathematics, astronomy, and physics, most of which were published in his two major works, Opticks and Principia. Among other innovations, he constructed the first reflecting telescope (now known as a Newtonian style telescope), invented integral calculus, and postulated a Universal Law of Gravity.

Newton was not just a mathematician and scientist, but was also important as a philosopher; Blake charged him with narrow-minded mechanistic materialism.

English mathematician/astronomer/physicist who first formulated a Law of Universal Gravitation. He also made important contributions to optics and invented the Newtonian reflecting telescope.
