Optics
Researchers at East China Normal University have developed a new imaging technique that captures ultrafast events in trillionths of a second, revealing both brightness and structural changes in a single shot. The method, called compressed spectral-temporal coherent modulation femtosecond imaging (CST-CMFI), tracks phenomena like plasma formation and electron movement. Yunhua Yao, the team leader, described it as a major advance for physics, chemistry, and materials science.

Irish mathematician William Rowan Hamilton developed a framework in the 1820s and 1830s that linked the paths of light rays and moving particles, an idea that later proved crucial to quantum mechanics. Born 220 years ago, Hamilton's work, including carving a formula on Dublin's Broome Bridge in 1843, built on earlier physics but revealed deeper connections only understood a century later. This insight helped shape modern theories of wave-particle duality.
