Why Does Light REALLY Bend?

A lot of optical illusions can be explained by Fermat's principle of least time, but why does light obey it? On a fundamental level, it all comes down to quantum mechanics, specifically quantum optics, where we use the famous "Feynman path integral formulation" to explain light through photons. ________________________________ VIDEO ANNOTATIONS/CARDS How Fast Is Light?    • How Fast Is Light?   Lagrangian Mechanics:    • Lagrangian Mechanics: How powerful is...   You Don't Know How Mirrors Work:    • You Don't Know How Mirrors Work   ________________________________ SUPPORT THE SCIENCE ASYLUM Patreon:   / scienceasylum   Advanced Theoretical Physics (Paperback): http://www.lulu.com/shop/nick-lucid/a...
