UrduThough a cornerstone of thermodynamics, entropy remains one of the most vexing concepts to teach budding physicists in the classroom. In The Physics Teacher, co-published by AIP Publishing and the American Association of Physics Teachers, T. Ryan Rogers designed a hand-held model to demonstrate the concept of entropy for students.

Way cool: UVA professor developing ‘freeze ray’ technology for the Air Force
You know that freeze-ray gun that “Batman” villain Mr. Freeze uses to “ice” his enemies? A University of Virginia professor thinks he may have figured out how to make one in real life.
Fondant: Where Baking and Thermodynamics Mix
Researchers in Germany have studied the kinetic and thermodynamic processes of sugar crystallization in the making of fondant. In Physics of Fluids, they combine a controlled kneading machine with light microscopy to precisely observe the process of fondant creation and link it to theoretical physics models.
“We’ve Got the Power”: Sandia technology test delivers electricity to the grid
For the first time, Sandia National Laboratories researchers delivered electricity produced by a new power-generating system to the Sandia-Kirtland Air Force Base electrical grid.
Nuclear rocket engine heat transfer research wins best student paper at NETS conference
A research paper about heat transfer inside the reactor of a conceptual liquid-fueled nuclear rocket engine by a University of Alabama in Huntsville (UAH) graduate student won best student paper at the American Nuclear Society’s recent Nuclear and Emerging Technologies for Space (NETS) conference
Our energy hunger is tethered to our economic past
Current world energy consumption is tied to unchangeable past economic production. And the way out of an ever-increasing rate of carbon emissions may not necessarily be ever-increasing energy efficiency—in fact it may be the opposite.
