William Markowitz

William Markowitz was a pioneering American astronomer best known for developing the modern method of measuring and understanding Earth's rotation and timekeeping. His work helped improve the precision of the atomic time scale, which is critical for accurate navigation, satellite technology, and global communication systems. Markowitz also played a key role in establishing Coordinated Universal Time (UTC), the standard time system used worldwide today. His contributions bridged astronomy and technology, ensuring we have a reliable and consistent way to measure time across the globe.
