A domino can knock over the next domino at about 1.5x larger (perhaps 2x larger) and this instant video classic from 2009 is a great example of this chain reaction. Watch University of Toronto's Professor Stephen Morris knock over a 1-meter tall domi...
If you place 32 metronomes on a static object and set them rocking out of phase with one another, they will remain that way indefinitely. Place them on a moveable surface, however, and something very interesting (and very mesmerizing) happens.

Quantum entanglement is a physical resource, like energy, associated with the peculiar nonclassical correlations that are possible between separated quantum systems. Entanglement can be measured, transformed, and purified. A pair of quantum systems i...
Muons, neutrinos, supersymmetric partners, the infamous Higgs boson - with so many different subatomic particles flying about, it's no wonder theoretical physics can be so confusing. That's why we made this (reasonably) simple guide to all the differ...
