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 ...

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 ...

Austrian physicist Erwin Schrödinger developed quantum theory’s wave equation, which describes quantum systems as waves that ...

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 ...

Quantum mechanics is concerned with the behavior of the tiniest of particles, and usually the mathematics behind it is relegated to this tiny realm. Now, a researcher from the California Institute of ...

For nearly a century, “reality” has been a murky concept. The laws of quantum physics seem to suggest that particles spend much of their time in a ghostly state, lacking even basic properties such as ...
