Mind = blown.

We experience the flow of time because it’s a natural outcome of the basic laws of physics. But we may need to build a whole ...

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 ...

In a recent paper, SFI Professor David Wolpert, SFI Fractal Faculty member Carlo Rovelli, and physicist Jordan Scharnhorst examine a longstanding, paradoxical thought experiment in statistical physics ...

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: ...

Entropy. Randomness. Disorder. Think of it as the universe’s tendency to move from ordered to disordered forms. It is a scientific concept of something that increases over time and something that is ...

I have always felt connected to the thermodynamic principle of entropy. I believed that my body at rest demonstrated the concept perfectly—and I now know that to be true, but not at all in the way ...

The flow of time in one direction is so intuitive, so immutable, that we take it utterly for granted. Things don’t fall up; broken pieces don’t reassemble; humans get older, so it goes. Yet time ...

Entropy is one of the most useful concepts in science but also one of the most confusing. This article serves as a brief introduction to the various types of entropy that can be used to quantify the ...

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 ...
