Antique balance demonstrating torque in action

An antique balance beautifully demonstrates torque in action. A simple yet powerful visual example of equilibrium and rotational physics at work, showing how forces balance in real life. #Physics #Tor ...
Physicists have used a machine-learning method to identify surprising new twists on the non-reciprocal forces governing a many-body system. The work is one of the relatively few instances of using AI ...
