The double slit experiment is just something you can do with any wave, and you can perfectly predict the result of the experiment with maxwell’s equations, which don’t involve any quantum at all. The weirdness is that at low enough intensity, where your power is so low that only one photon can be in your system at a time, you still see the pattern form, but as a statistical distribution. Not just that, but why would the photon concentrate itself to a small spot on the detector surface? This is perhaps the biggest mystery in quantum mechanics, how individual particles combine into macroscopic stuff we can see with our eyes

9:15 This isn’t quite right. Any detector like this has bins that the photon can go in, and it is impossible for more than one bin to be triggered at a time, because that would violate energy conservation. So all you know is that the photon ended up somewhere inside one of these bins. That is not the same as knowing exactly where it was, only putting limits by forcing the photon to choose a bin. And, the really wacky part is that there’s no physical reason that the photon isn’t hitting the bins in the expected distribution, but the entanglement of the photon with the observer means that there’s now a distribution of observers, where each superposed state of the observer sees one pixel being hit. That is, there’s no good reason that quantum phenomena should hit some wall beyond which they don’t happen. Rather, entanglement is what causes the gradual transition to macroscopic classical behavior

11:45 Well this is just because polarizers don’t block, they polarize. A nice sleight of hand that can be accidentally made.

10:35 The photon doesn’t “snap”, into one or the other, it becomes entangled with the polarizer. Every part of the system that the photon interacts with becomes entangled with it, including you, the final observer. The Copenhagen interpretation may be easier to explain, but it just doesn’t stand up to scrutiny for the exact reasons you’re bringing up. Paradoxes don’t indicate that nature is broken, they indicate that our point of view is broken

6:15 It’s actually pretty easy to produce a single photon stream. Hell, you could even do it with a bunch of sunglasses and a lamp. The hard part is detecting single photons. A single photon is so ineffectual that it’s very difficult to measure compared to a stream of quadrillions
