More than a century before quantum mechanics was born, Irish mathematician William Rowan Hamilton stumbled onto an idea that would quietly foreshadow one of the deepest truths in physics. While ...

Rydberg atoms are atoms with one or more outer electrons excited to very high energy levels, which interact very strongly with each other. These atoms are widely used to run quantum simulations and ...

How do lenses work? How do they form images? Well, in order to understand how optics work, we have to understand the physics of light. In this episode of Crash Course Physics, Shini talks to us about ...

Researchers from Nanyang Technological University, Singapore (NTU Singapore) have found a new way to produce X-rays with wavelengths in what is called the "water window." This new method holds promise ...

Historian Ivan Malara has identified handwritten annotations by Galileo Galilei in the margins of a roughly 500-year-old copy ...

Integrated optics is a system of light-controlling components combined into a single device. The ultimate aim is to create miniature optical circuits similar to the silicon chips that have ...
