What is weak interaction? I need easy and short answer.
I can't understand the definition of weak force.
Why is it so difficult? Bosons, Mesons, Fermions, parity etc.
Why the fundamental force is too hard to understand?
(I give time for typing this. But it's hard to integrate those forces.)
Gravitational : Force between masses.
Electromagnetic : Force between charges.
Strong interactions : Strong force in nucleus which locks nuclei from Electromagnetic force.
Those are intuitively understandable.
But weak interaction? What is it?
