1629 – 1695
Christiaan Huygens was a Dutch mathematician, physicist, and astronomer whose work bridged the scientific revolutions of Galileo and Newton. He made foundational contributions to mechanics, optics, and horology, including the wave theory of light and the invention of the pendulum clock. His rigorous mathematical approach to natural philosophy helped establish the methodology of classical physics.
Formulated the wave theory of light in Traité de la Lumière (1690)
Invented the pendulum clock, revolutionizing timekeeping accuracy
Discovered Saturn's moon Titan and correctly identified Saturn's rings
Derived the laws of centripetal force and elastic collision
Pioneered probability theory in De Ratiociniis in Ludo Aleae (1657)
