b'ISAAC NEWTON Isaac Newton, the most famous mathematician of the 17th century, experienced several nervous breakdowns and was known for fits of rage toward people who disagreed with him. He appears to have had mild schizophrenia or bipolar disorder. Newtons mental illness seems to have inspired his discovery of calculus and the laws of mechanics and gravity. During a manic period in his early 20s, Newton worked night and dayoften forgetting to sleep and eatand made most of his important discoveries. But his insomnia and anorexia often induced periods of depression, and he had memory loss, confusion, and paranoia. Newtons choices for treatment included bloodletting, purging, potions of mixed sedatives, prayer, a walk in the woods, or a good book.
