Your WINDOWS Don't Actually Let Light In — Feynman Explains What Really Happens

Описание: You look through a window and assume the glass just "lets light in." But the physics tells a completely different story — one involving quantum probability, electron radiation, and the total destruction and reconstruction of every photon that touches the glass.
In this video, we explore what Richard Feynman explained in his famous lectures on quantum electrodynamics about the true interaction between light and transparent materials. Drawing on his beautifully accessible treatment of partial reflection, photon probability amplitudes, and the absorb-and-re-emit mechanism that actually creates transparency, we break down why your window is one of the most sophisticated light-processing devices in your home — and why the "sunlight" in your room isn't really sunlight at all.

If the photons in your room were created by the glass, is the light you see still "sunlight" — or did your window create something new entirely? Where do you draw the line?
