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

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 ...

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 ...

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 ...

Topological water currents could exist in Earth’s oceans, according to physicists in the France and the US. The team has made a connection between the physics that gives topological insulators their ...
