  1. 3:25 what’s funny is we have no issue with electric and magnetic forces acting at a distance. But it is equally mysterious.

  2. 16:19 I don’t think that’s true. I think what gets put into the body of accepted knowledge is whatever is profitable or valuable in some way to someone. E.g Can you make enough money off this piece of information? Either by getting money from speculators or from consumers. Like… how is it that the large hadron collider receives so much money? Or why do space telescopes get built? Money funds those projects somehow for some reason, and I’m pretty sure it’s not just because we’re curious… someone thinks they can make money/value off their investment.

  3. 7:09 similar, I guess, to the proportion of people on the cover of Times and Forbes who end up being evil.

  4.  @wallacegrommet9343  sure. And I suppose there is the concept where electric charge and magnetism have fields that similarly get told “how to curve and tells things how to move”. It still feels something is missing and mysterious.

  5.  @hedgehog3180  that doesn’t makes sense. I don’t understand how photons magically appear from the EM fields when charged particles move as described by tensors. The electric fields are uniform around the charged particle, so the EM field from that particle propagates in all directions. How does that get quantised into a photon that only travels in one direction? How does a moving charged particle cause photons to be emitted? I understand the EM field model, besides the acting at a distance thing. But I can quite wrap my head around the photon model. There are quite a few dissonances and missing pieces or not well defined pieces with that model.

  6. The tape in a Turing machine contains characters from an alphabet... the alphabet isn’t just limited to 0 and 1. The alphabet can contain anything. The alphabet can be letters, numbers, objects, or even other Turing machines.

  7. It all seems very binary. I’m still not sure where the extra computational power comes from.

  8. Here’s an idea... YouTube could learned the style of titles a user likes to click. Eg. I usually skip videos with click-baity titles because 95% of the time I know the content is going to be mediocre at best. If YouTube only showed me non-click-baity titles, this would likely improve my overall watching experience. I know some people love the click-bait... so YouTube could show the click-bait to those people and improve their overall experience. The benefit of this is that channels like Veritasium can market to a particular audience rather than to the general masses.

  9. 27:44 it sounds like F = ma is a simplification; an edge case; a specific scenario. But there are more solutions when you don’t cross out so many terms. Maybe I misunderstood though.

  10. Wow!

  11. 27:44 Is it actually a parallel universe? Or just a different place in this universe? Eg the coordinates on the other side of the black hole?

  12. So what happens when someone gets electrocuted? Is that the fields too?

  13. We could measure the one way speed of light by shooting some photons along an ellipticalish path around a black hole such that the the returned light hits the same detector. We just need to find a black hole near enough to Earth so we get the results within a reasonable timeframe and calculate the path such that the beam of light will return to the future position of the detector. Easy peasy.

  14. Ok I see all the flaws in what I said. But the question that remains for me is: does the logic in the video hold up for curved paths of light (relative to us)
