Misconceptions about the universe

This video introduces the Hubble sphere and how the rate of expansion of space can be used to explain how we see very distant objects that are travelling faster than light. The limitation to the observable universe is the particle horizon (where the time is too great for light to have reached the Hubble horizon).[...

Jetpack rocket science

This video takes a light-hearted look at motion. It applies Newton’s second and third laws to explain how motion occurs in the space shuttle and a jetpack. Misconception about reaction forces are identified (the need for the ground/lake for a reaction force to be generated) for motion to happen. This explains how...

How special relativity makes magnets work

This video shows how electromagnetism can be explained using either models of magnetism or of electric fields, induced by length contraction caused by special relativity. Length contraction (Lorentz contraction) occurs to anything that is moving – relative to something moving slower. The explanation shows how moving...

Anti gravity wheel

This video demonstrates how a 19kg flywheel, attached to a 1 metre shaft can be lifted easily when the flywheel is spinning, yet almost impossible when stationary. It appears that the rotation reduces the weight of the flywheel.  However, when standing on scales and holding the apparatus, the weight does not...
