What is a fake force? Let me illustrate with an example. Suppose you want to use Newtonian mechanics. You know - where the net force is the rate a which the momentum changes with time? Or maybe you ...

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, ...

Things spin around us, under us and above us every day. When something is spinning, it means that it is turning or rotating quickly around an axis (point). That point is usually in the center, but it ...

21 October 2025 – It sounds bizarre, but they exist: crystals made of rotating objects. Physicists from Aachen, Düsseldorf, Mainz and Wayne State (Detroit, USA) have jointly studied these exotic ...

In laboratories from Brazil to Munich, researchers are learning to grab matter with sound alone, sculpting ultrasonic waves into invisible “hands” that can lift, push, and rotate objects without a ...

July 25 (UPI) --A research team led by engineers with the University of California San Diego has shown off a robotic hand that can rotate an object in its palm using touch-based sensors rather than by ...

If you’ve never heard of Bernoulli forces, you’ll certainly have experienced them. These are the forces that keep aircraft aloft, that draw fuel into your car’s carburetor and cause spinning tennis ...
