Modeling What Happens to Frozen Rotating Lasagna

Things take a turn in this roundabout technical study of lasagna: “Multiphysics modeling of microwave heating of a frozen heterogeneous meal rotating on a turntable,” Krishnamoorthy Pitchai, Jiajia Chen, Sohan Birla, David Jones, Ric Gonzalez, and Jeyamkondan Subbiah, Journal of Food Science, vol. 80, no. 12, 2015, pp. E2803-E2814.

Counter-Rotation Inside a Glass of Beer Shaken Stirringly

A round of surprise appears in a glass of beer—or a glass of coffee or tea—when you shake it stirringly. Details are in this study: “Counter-Rotation in an Orbitally Shaken Glass of Beer,” Frédéric Moisy, J. Bouvard, and Wietze Herreman [pictured below], EPL [Europhysics Letters], vol. 122, no. 3, no. 34002, 2018. The authors, at Université […]

The Coriolis effect, trouser leg preference, and human rotation

Theoretical and practical investigations have shown that the ‘Coriolis effect’ (see video above) can substantially influence physical systems such as the trajectory of cannon balls and the rotation of meteorological phenomena. But very little research has addressed the issue of whether it might also affect human behaviour. For example, might the Coriolis effect affect which […]

Ten Tops List [videos of spinning tops] — 2011

There are lots of top ten lists, but this is the first Ten Tops List. Here are ten videos of spinning tops that scientists find interesting and or amusing. [Want to take a whirl at learning the science of spinning tops? Download (free) Professor John Perry’s 1890 book Spinning Tops— The “Operatives’ lecture” of the British […]

Dog rotation: not always pleasant

Dog rotation can be pleasing (as in the instance we described recently). But sometimes it’s not — think about the rotation described in this study: “Gastric torsion in the dog—II. Nonsurgical treatment by aspiration of gastric contents during repeated rotation of the animal“, B. Funkquist and N. Obel, Journal of Small Animal Practice, Volume 20, […]
