In 1673, Dutch mathematician and scientist Christiaan Huygens greatly improved the pendulum clock, enhancing its precision and reliability. By elongating the pendulum and introducing cycloidal designs, Huygens increased clock accuracy, pivotal for maritime navigation. This advancement enabled mariners to better determine longitudinal positions, influencing the Age of Exploration and promoting safer, efficient trade. Huygens' work significantly impacted timekeeping, fostering cultural and economic integration globally.
