We describe the construction, validation, and testing of a concept inventory for an Introduction to Physics of Semiconductors course offered by the department of physics to undergraduate engineering students. By design, this inventory addresses both

Sometimes it takes little to keep this physicist happy on an airplane. A window seat, where the plane’s shadow is visible or has disappeared into the distance, provides the opportunity to observe a variety of phenomena associated with sunlight that

Electromagnetic induction, represented by either Faraday’s law or the Lorentz force law, produces many paradoxes requiring careful examination and application of these laws. The paradoxical example of induction, presented herein, arose in a class a

We develop the open dog-flea model to serve as a check of proposed non-equilibrium theories of statistical mechanics. The model is developed in detail. Then it is applied to four recent models for non-equilibrium statistical mechanics. Comparison of

The Cartesian diver is an old and useful demonstration of fluid-related phenomena, including Archimedes’ and Pascal’s principles. While the diver gets its name from the scientist and philosopher Rene Descartes, the first written description of th

Frost injury patterns are commonly observed on the warm-season turfgrass species bermudagrass (Cynodon species Rich.), zoysiagrass (Zoysia species Willd.), and buffalograss [Bouteloua dactyloides (Nutt.) J.T. Columbus] in cool-temperate and subtropic

A tilted two-layer colloidal system is constructed for the study of force-assisted barrier-crossing dynamics over a periodic potential. The periodic potential is provided by the bottom layer colloidal spheres forming a fixed crystalline pattern on a

For more than 30 years, Albert A. Bartlett published “Thermal patterns in the snow” in this journal. These are patterns produced by heat sources underneath the snow. Bartlett’s articles encouraged me to pay attention to patterns in snow and to

The Brownian motion of molecules at thermal equilibrium usually has a finite correlation time and will eventually be randomized after a long delay time, so that their displacement follows the Gaussian statistics. This is true even when the molecules
