In pressure relief systems, accurately estimating temperature changes during fluid flow is vital for relief piping ...

Time feels like the most familiar thing in the world, yet it hides one of physics’ hardest questions: why do we only remember ...

Two physicists at the University of Stuttgart have proven that the Carnot principle, a central law of thermodynamics, does not apply to objects on the atomic scale whose physical properties are linked ...

Abstract: Solid oxide fuel cell (SOFC) is recognized as piv otal technological component in the utilization of hydrogen energy, drawing extensive interest due to their high efficiency, low emissions, ...

A golf-course layout is a pretty basic concept. You start at the first hole, then move to the second, and then sequentially until you reach the 18th. Unless, that is, it’s a reversible course.

While quantum entanglement mimicks the first law of thermodynamics in terms of entropy in a system, scientists wonder if the second law—especially the part about reversibility—could hold true. A new ...

Just over 200 years after French engineer and physicist Sadi Carnot formulated the second law of thermodynamics, an international team of researchers has unveiled an analogous law for the quantum ...

We study a process of heat transfer between a body of heat capacity C(T) and a sequence of N heat reservoirs, with temperatures equally spaced between an initial temperature T0 and a final temperature ...

Guillaume Verdon stands before me with a new kind of computer chip in his hand—a piece of hardware he believes is so important to the future of humanity that he’s asked me not to reveal our exact ...

However, while thermodynamics enforces an irreversible flow of time, the fundamental laws of physics, such as Newtonian mechanics, electromagnetism, and the Schrödinger equation in quantum mechanics, ...

Picture Victorian London, but its skies are filled with airships. Steam-powered robots crowd the streets, mingling with people in top hats and petticoats. That type of retrofuturistic mash-up is the ...
