The One Question About LIGHT That Feynman Couldn't Answer

Why does glass reflect exactly 4% of light? Why not 5%? Why not 3%? This seems like a simple question. But when you dig deeper, you find something unsettling. When you fire a single photon at glass, it either reflects or passes through. Every time. No splitting, no half-measures. So how does it "decide"? How does one photon "know" that exactly 4 out of every 100 photons should bounce back? This mystery haunted Isaac Newton. It confused physicists for centuries. And when Richard Feynman developed his Nobel Prize-winning theory of quantum electrodynamics, even he admitted he couldn't fully explain what was really happening. In this video, we explore the question Feynman couldn't answer: the mystery behind 1/137, the "magic number" that governs how light and matter interact. This isn't just a physics curiosity. It's one of the deepest unsolved problems in all of science. In this video, we explore Feynman's famous QED lectures to understand what the fine structure constant is, why every theoretical physicist has it "written on their wall," and why Feynman called it "one of the greatest damn mysteries of physics." Drawing primarily from his 1985 book "QED: The Strange Theory of Light and Matter" and his Messenger Lectures at Cornell, we walk through the partial reflection paradox, the double-slit experiment, and why even our most accurate theory cannot tell us where these numbers come from. 📚 SOURCES Richard P.
