In this video, we break down the physics behind a tipping or sliding block! Learn how to calculate torque and friction to determine the exact moment when a block will tip or slide. Whether you're ...

One of my students showed me this game, [Fantastic Contraption](http://fantasticcontraption.com/). The basic idea is to use a couple of different "machine" parts to ...

Torque wrench: artist’s impression of the Casimir torque (purple streaks) acting on two solids (blue) against a background of quantum fluctuations (silver spikes). (Courtesy: Jeremy Munday) A very ...

The 'spin-transfer torque effect' could provide a powerful means of controlling the orientation of spins with electric currents rather than magnetic fields in future spintronic devices. Quantitative ...

Short demo: The fan in a vacuum pushes air out, creating a system of low pressure. This in turn creates a system of low pressure within the bag, allowing for an entertaining demonstration of the power ...
