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: ...

MR. SWINBURNE has directed attention to an obscure point in my letter of November 10 which is calculated to produce quite the contrary impression to what I intended. In defining available energy ...

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 ...

I recently led a webinar on the laws of thermodynamics, which got me thinking: A business is very much a closed system, such as a universe. Therefore, if entropy is always increasing in a closed ...

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 ...

Have you ever tried turning the spoon back after stirring jam into a rice pudding? It never brings the jam back into the spoon. This ever-increasing disorder is linked to the notion of entropy. In a ...

There are some things in life that just sort of happen. Desks get covered in dust and scraps of paper. Clothes get dirty and the laundry basket fills up. Weeds slowly creep across an untended ...

FROM time to time controversies have appeared in various journals regarding that most difficult of all physical conceptions—entropy. I have purposely avoided passing any opinions as to the merits of ...

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 ...
