Interesting formations: an example of droplet shapes that are produced when an electric field is applied to an oil mixture. (Courtesy: Aalto University) When a simple system of two liquids is driven ...

I’ve already made the argument that numerical models (using computer code) should be an integral part of the introductory physics course. But what if you don’t know where to start? Suppose you are ...

Controlling magnetic states in materials typically requires continuous power or only works in rare, specialized systems. Researchers developed a general theory showing how electric fields can ...
