Description: 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? youtu.be/a9T26ItpcDA Lagrangian Mechanics: youtu.be/MIBfKJHMWHU You Don't Know How Mirrors Work: youtu.be/rYLzxcU6ROM ________________________________ SUPPORT THE SCIENCE ASYLUM Patreon: patreon.com/ScienceAsylum Advanced Theoretical Physics (Paperback): lulu.com/shop/nick-lucid/advanced-theoretical-physics-a-historical-perspective/paperback/product-24250687.html Advanced Theoretical Physics (eBook): gumroad.com/l/ubSc Merchandise: shop.spreadshirt.com/scienceasylum ________________________________ HUGE THANK YOU TO THESE PATRONS Warden of the Asylum: YDT Asylum Counselors: Matthew O'Connor Asylum Orderlies: William Morton Einsteinium Crazies: Albert B.
