So, I've been reading up on quantum mechanics and the double slit experiment.
If I understand it correctly, the reason why attempting to measure which slit does a particle go through is because of the Heisenberg uncertainty principle: we can only either know the velocity or the position of a particle, but not both.
So in other words, when measuring which slit a particle goes through, we know the position, but we don't know the velocity. So, the interference pattern disappears, but the probability distribution of the velocity suddenly becomes unknown.
Does that sound right?
