The second law of thermodynamics says, in simple terms, entropy always increases. This principle explains, for example, why you can't unscramble an egg. When you purchase through links on our site, we ...

Entanglement is central both to the foundations of quantum theory and, as a novel resource, to quantum information science. The theory of entanglement establishes basic laws that govern its ...

When French engineer Sadi Carnot calculated the maximum efficiency of a heat engine in 1824, he had no idea what heat was. In those days, physicists thought heat was a fluid called caloric. But Carnot ...

In a previous article in this series addressing evolution, I commented that some scientists, in an effort to avoid admitting the possibility of a God, will adhere to a theory even if it goes against ...

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 ...

In the 19th century, James Clerk Maxwell, who developed the modern theory of electromagnetism, introduced Maxwell's demon and the theory of stochastic thermodynamics was conceived. Maxwell's intent is ...

The most accepted version of the third law of thermodynamics, the unattainability principle, states that any process cannot reach absolute zero temperature in a finite number of steps and within a ...
