Though a cornerstone of thermodynamics, entropy remains one of the most vexing concepts to teach budding physicists in the classroom. As a result, many people oversimplify the concept as the amount of ...

Of the known things in the universe, black holes are among the most extreme. They pack huge amounts of mass densely into a small area, producing gravity that is so strong that even light cannot escape ...

A new study conjectures that simple thermodynamics principles can predict the final state of a non-spinning binary black hole ...

One of the enormous conceptual ideas that came along with Einstein's theory of relativity was the surprise that time itself, long considered fundamental and universal, is actually relative. Different ...

Steepest Entropy Ascent Quantum Thermodynamics (SEAQT) is a theoretical framework that unifies quantum mechanics and thermodynamics to describe the intrinsic non-equilibrium evolution of isolated ...

How it works When laser light passes through a cavity filled with atoms, part of it can do useful work. In this example the work is charging a quantum battery (top). The rest of the light turns into ...

The laws of physics seemed to forbid a strange variety of black holes that could have zero temperature. Columnist Jacklin ...

Every moment that passes finds us traveling from the past to the present and into the future, with time always flowing in the same direction. At no point does it ever appear to either stand still or ...

Though a cornerstone of thermodynamics, entropy remains one of the most vexing concepts to teach budding physicists in the classroom. Physics teachers designed a hand-held model to demonstrate the ...
