Natural crystals fascinate with their vibrant colors, their nearly flawless appearance and their manifold symmetrical forms. But researchers are interested in them for quite different reasons: Among ...

Lenz’s Law is one of those physics tricks that look like magic if you don’t understand what’s happening. [Seth Robinson] was inspired by the way eddy currents cause a cylindrical neodymium magnet to ...

The discovery of superconductivity more than a century ago has significantly changed our world. The story began in 1911 when the Dutch physicist Heike Kamerlingh Onnes observed that the electrical ...
