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 ...

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 ...

Recent research reveals that quantum mechanics can supersede the second law of thermodynamics at the atomic scale, ...

The second law of thermodynamics is one of those puzzling laws of nature that simply emerges from the fundamental rules. It says that entropy, a measure of disorder in the Universe, must always ...

Can quantum systems become more disordered, as thermodynamics would predict? Yes, they can - if a proper definition of "entropy" is used. It is one of the most important laws of nature that we know: ...

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 ...

According to the third law of thermodynamics, the entropy of a perfect crystal is zero when the temperature of the crystal is equal to absolute zero (0 kelvin). When you purchase through links on our ...

Since their discovery at Drexel University in 2011, MXenes — a family of nanomaterials with unique properties of durability, conductivity and filtration, among many others — has become the largest ...

WASHINGTON, Sept. 6, 2023 – 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 ...
