A century after Einstein predicted the outcome from a black hole collision, Frans Pretorius helped pave the way for the actual discovery of the ripples that would expand our understanding of the ...

An introduction to how Maxwell’s equations lead to electromagnetic plane waves. This lesson explains the physics behind wave ...

More than a century before quantum mechanics was born, Irish mathematician William Rowan Hamilton stumbled onto an idea that would quietly foreshadow one of the deepest truths in physics. While ...

In this lesson, we introduce the one dimensional wave equation and explore how it appears in electrodynamics. This video explains the basic concepts, physical meaning, and mathematical form of the ...

It isn’t often that physics produces news that diverts the mainstream media from politics, crime and sports. But, now, in the space of four years’ time, physicists have twice elevated the intellectual ...
