  • Ok, so the main video was talking about neutrinos shapeshifting via superposition, and a similar

  • thing happens if you take two pendulums and attach them with a springon their own,

  • theyll want to do one of two things: either swing together in the same direction, or exactly

  • opposite each other, and when theyre opposite each other, they swing slightly faster because

  • of the help of the spring.

  • But perhaps you interact with the pendulums, and push one of them to start it swinging.

  • When you think about it, the first pendulum swinging by itself is actually a superposition

  • of both swinging the same way and both swinging opposite ways, combined so that the swinging

  • of pendulum two cancels out.

  • However, because the twoon their ownstates of the pendulums don’t swing with

  • the same rate, they won’t cancel out for pendulum two forever, and eventually it will

  • be the only one swinging, and pendulum one will have stopped.

  • And then later, itll be pendulum one, and then pendulum two, and so on.

  • So the states you interact with, just one pendulum swinging, can oscillate back and

  • forth between each other, swapping identities, because theyre superpositions of the non-interacting

  • states, and those states have different frequencies.

  • Other than a few pesky details to do with quantum mechanics, this is essentially what

  • happens with neutrinos!
