How hard can it really be to decode alien physics and engineering? It’s gotta map to our own physics - I mean, we live in the same universe. We start by noticing that the alien technology seems to use good ol’ fashioned electronics, even...

How to visualize quaternions, a 4d number system, in our 3d world

The formula for the cross product can feel like a mystery, or some kind of crazy coincidence. But it isn't. There is a fundamental connection between the cross product and determinants.

In this video Paul Andersen explains how a charge particle will experience a magnetic force when it is moving through a magnetic field. The right-hand rule is described as a method for determining the direction of the force. The...

What happens if you multiply things that aren't numbers? And what happens if that multiplication is not associative?

This content provides a step-by-step solution for calculating the torque on a particle about the origin, given its position vector and an applied force vector, using unit-vector notation. It then demonstrates how to find the angle...

This content defines torque for a particle moving along any trajectory relative to a fixed point, not just a fixed axis. It establishes torque as the vector cross product τ=r×F, explaining its direction using the right-hand rule and its...

This content introduces the concept of torque as the twisting or turning force that causes rotation, explaining its dependence on the applied force and the perpendicular distance from the axis of rotation. It delves into calculating...

This content defines angular momentum (ℓ) for a particle as the cross product of its position vector (r) and linear momentum (p), i.e., ℓ=r×p=m(r×v). It clarifies that angular momentum is a vector quantity defined with respect to a...
