RE: Wave-particle duality aka the central pillar of quantum mechanics

Then Feynman comes around and asks:

  • What if the screen contains more than 2 holes?
  • What if there are several screens with holes behind one another?
  • What if there infinitely many screens with holes behind each other?
  • What if there are infinitely many screens with so many holes that there are no screens anymore at all?

And suddenly you have discovered the path integral :D

    I'm not sure whether this is a factual anecdote but this is what Feynman is supposed to have asked his professor back then.
    And mathematically rigorously speaking this is how you could construct a path-measure (compare Wiener measure for Brownian motion). It might have been a very educated question if this is really true :D
