THAT Regnault made a number of experiments similar to some of those described by Joule and Kelvin in their papers on the thermal effects of fluids in motion does not seem to be commonly known; at all ...

The fun part about crycoolers is that there are so many different and exciting ways to make stuff cold, based on a wide variety of physics. This is why after first exploring the Stirling/GM cycle and ...

This apparatus, held in London's Science Museum, has some significant purpose — or curiosity value — in the history of physics. Can you guess what it is? James Prescott Joule was the son of a wealthy ...

A new apparatus is described for measuring the isothermal Joule-Thomson coefficient. The results obtained agree well with other direct measurements and also with adiabatic Joule-Thomson and ...
