Almost exactly 200 years ago, French physicist Sadi Carnot determined the maximum efficiency of heat engines. The Carnot ...

Atomic, molecular and optical physics lies at the intersection of quantum mechanics and electromagnetic theory, providing the fundamental framework for our understanding of matter and light.

Editor’s Note: Professor WERNER HEISENBERG, who was born in Duisburg in 1901, was awarded the Nobel Prize in Physics in 1932 for his work on the quantum theory. A member of the faculty of the ...

An international research collaboration led by the University of Surrey's Nuclear Physics Group has overturned the long-standing belief that the atomic nucleus of lead-208 (²⁰⁸Pb) is perfectly ...

Physicists are learning to treat light not as an untouchable beam that simply passes through matter, but as something that ...

According to all the known laws of physics, the Big Bang should have created a Universe consisting of both matter and ...

The 53rd Annual Meeting of the American Physical Society’s Division of Atomic, Molecular and Optical Physics begins May 30. Scientists from around the world will present new findings on atoms, simple ...
