Volume 54 Issue 6, September 2016
The Physics Teacher
This month's cover features colorful dice and hard candies to help teach about entropy. Jeffrey Phillips' article, The Macro and Micro of it Is that Entropy Is the Spread of Energy, emphasizes that it is better to associate entropy with energy spread than with disorder.
In recognition of The Physics Teachers' volunteer referees/reviewers the issue includes a Guest Editorial, Thank You to our Refrees May 2015-May 2016!
