Does electron has definite path?

[bhobba]

One could always say that light is made up of arrows which go through each other!.."

Well leaving aside the meaning of the little arrows in that layman popularisation - why do you think the arrows going through each other is the same as the particles going through each other?

The theory he helped father says photons don't necessarily go though each other - as the Wikipedia article I linked to details.

How can such a dichotomy occur?

Maybe its like the following from the FAQ:
https://www.physicsforums.com/threads/is-light-a-wave-or-a-particle.511178/
'So there is no duality – at least not within quantum mechanics. We still use the “duality” description of light when we try to describe light to laymen because wave and particle are behavior most people are familiar with. However, it doesn’t mean that in physics, or in the working of physicists, such a duality has any significance.'

QM is a theory about observations that appear here in the classical common-sense world. What its doing when not observed is anyone's guess. For some reason you want to doubt it. To argue it you are going to have to go beyond layman presentations.

The first step will be in detailing the exact experimental set-up to observe the path of a single electron. Oh - and you are also going to have to demonstrate the act of observation doesn't affect that path - in violation of the uncertainly principle. Good luck - Einstein tried and failed to get around it - but you are welcome to give it a shot.

Thanks

[Nugatory]

Photons can pass through each other. In a given volume, we can have photons such that there is no space without photon (with the electron which has to be observed).

That logic would work if these quantum particles had definite positions and occupied definite volumes of space - but they don't. If they did, we wouldn't have any difficulty assigning them definite paths, and this thread never would have started.

This thread is done.
