Christiaan Huygens
Dutch mathematician and physicist (1629–1695)
Christiaan Huygens, Lord of Zeelhem was a Dutch mathematician, physicist, engineer, astronomer, and inventor who is regarded as a key figure in the Scientific Revolution. In physics, Huygens made seminal contributions to optics and mechanics, while as an astronomer he studied the rings of Saturn and discovered its largest moon, Titan. As an engineer and inventor, he improved the design of telescopes and invented the pendulum clock, the most accurate timekeeper for almost 300 years. A talented mathematician and physicist, Huygens authored the first modern treatise where a physical problem was idealized using mathematical parameters, while his work on light contains the first mathematical and mechanistic explanation of an unobservable physical phenomenon.
