Is interaction first or field?

    Field Interaction

without the interaction we can't measure the field so interaction should come first which is against the literature.

Euuh, what do you mean.

In QFT fields are used in order to describe the interaction. The particles involved (both fermionic matter fields as well as bosonic force fields) are the quanta of these fields acquired by the second quantization.

don't think that the interaction generates the field. The interaction itself is described by the field.

There is no distinction between "interaction" and "field".

(That's really what marlon just said!)

That's a very efficient way to put it,...nice :smile: , right on brother :cool:

Thread 'Quantum behaviour of an electron around a positively charged sphere'

If we release an electron around a positively charged sphere, the initial state of electron is a linear combination of Hydrogen-like states. According to quantum mechanics, evolution of time would not change this initial state because the potential is time independent. However, classically we expect the electron to collide with the sphere. So, it seems that the quantum and classics predict different behaviours!
