Over the past decades, the mathematical formulation of physical theories has evolved to provide a unified framework that bridges classical mechanics, quantum mechanics and quantum information theory.

Physicists at Stevens Institute of Technology used Christiaan Huygens' 350-year-old theorem, which explains the workings of pendulums and planets, to reveal new properties of light waves. (Courtesy: ...

A branch of physics that deals with the effects of energy and forces on the motion of physical objects, based on the work of Isaac Newton and on three-dimensional Euclidean geometry, also called ...
