In 1672, Dutch mathematician and scientist Christiaan Huygens revolutionized timekeeping with his development of the pendulum clock. This invention improved clock accuracy dramatically, reducing errors to less than 10 seconds a day from 15 minutes. Huygens’ innovation was pivotal for precise navigation and time management, essential for maritime exploration and trade. This technological advance supported economic development by enabling efficient scheduling, record-keeping, and reliable long-distance commerce.
