Science popularization has its legends and heroes, just like any other field, though I’ve heard no plans as yet to open a Hall of Fame. Should that day come, one of the first inductees would ...

If the number of states is W, the entropy is given by Boltzmann's famous formula S = kB ln W. For isolated systems, the standard (textbook) approach is to take some energy interval Δ E around the ...

Ludwig Boltzmann is best known as the Austrian physicist who wrote down the statistical formula for entropy, but if the physics thing hadn’t worked out, he would have made an excellent travel writer.

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 ...
