Physicists studied crystals made of rotating objects that fragment easily, show unusual defects, and follow a new theory predicting their unique behavior. (Nanowerk News) Physicists from Aachen, ...

The world is filled with rotating objects—gyroscopes, magnetic spins, and more recently, qubits in quantum computers. For example, the atomic nuclei in our bodies precess at megahertz frequencies ...

Hmmm: Why do some players invert the Y-axis in video games? To many, it seems strange to make down mean up and up mean down. For inverters like me, it feels natural – the default setting is as awkward ...
