| Dutch scientist Christiaan Huygens made significant advancements in optics, astronomy, and physics. He developed the theory that light is composed of waves and invented new ways of making lenses. He built telescopes that enabled him to discover a moon of Saturn. He also was the first to use pendulums to keep time, and determined the relationship between the length of a pendulum and the time taken by its swing. | ||||||
