September 2016 TPT cover

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!


With the start of the 2016 football season you may want to reflect on Deflategate with two articles that look at the physics of this problem.  Speaking of sports, we've linked to two Olympics related articles under Additional Resources on this page.
