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 have never thought about it that way Naively, I would said yes, it works :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
:)
