Name: 7A55.20 Young's Double Slit Interference with single photon particles
Duration: 3 min
Description: Brown University's physics demonstrations show Young's double slit first with light waves, then with single photons: the light version of this section's one-at-a-time test. Look for the section's two conclusions: each photon registers as one localised detection, yet the detections together obey the two-slit pattern.

3. Two-Slit Experiment; Quantum Weirdness
MIT OpenCourseWare · Robert Field · 2017
Professor Robert Field's lecture from MIT's 5.61 Physical Chemistry (Fall 2017) works through the two-slit experiment, the evidence that light and matter behave as both waves and particles, and the uncertainty principle. University-level and unhurried, with the two-slit discussion starting about six minutes in: watch it after Part 4, and treat its uncertainty-principle discussion as a preview of chapter 8.

Quantum Physics I
MIT OpenCourseWare · Allan Adams · 2013
Allan Adams' celebrated course starts from superposition and the experimental facts, builds the wavefunction, operators and the Schrödinger equation, then tours scattering, hydrogen, identical particles and band structure before closing on entanglement and Bell's theorem. Calculus and a little linear algebra are enough to keep up.

Quantum mechanics and the double slit experiment
Fermilab
Fermilab's Dr. Don Lincoln introduces the big ideas behind the most famous experiment in quantum physics: what waves do at two slits, what particles do, and why quantum objects fit neither picture. It sets you up for Parts 1 to 4; notice the questions it leaves open, because Parts 5 to 7 answer them.

The Delayed Choice Quantum Eraser, Debunked
Sabine Hossenfelder
Sabine Hossenfelder takes apart the claim that the delayed-choice quantum eraser rewrites the past, building up from the double slit and entanglement. Watch it after Part 7: her account of why fringes appear only in sorted subsets of the data is exactly the lesson's.

Wave-Particle Duality Explained with Double Slit Experiments | CHRISTMAS LECTURES1999 | Neil Johnson
The Royal Institution · Neil Johnson
A clip from Neil Johnson's 1999 Royal Institution Christmas Lectures that explains wave–particle duality with double-slit demonstrations. Use it as a warm-up for Feynman's three runs: for each demonstration, ask whether the result is lumps that add, like bullets, or bands that interfere, like water waves.
