Penn Engineers have developed a mathematical "Rosetta Stone" that translates atomic and molecular movements into predictions ...

A team of researchers at the Ming Hsieh Department of Electrical and Computer Engineering has created a new breakthrough in photonics: the design of the first optical device that follows the emerging ...

Nernst's theorem—a general experimental observation presented in 1905 that entropy exchanges tend to zero when the temperature tends to zero—has been directly linked to the second principle of ...

Quantum mechanics and classical physics don’t always get along, and can sometimes form apparent paradoxes where observed quantum behavior violates well-established physical laws. In quantum mechanics, ...

Technically speaking, an engine is a device that converts some form of energy into mechanical energy. Taking that definition ...
