I'm struggling to keen my mind open when visualising fundamental particles. I've only been reading about quantum/particle physics for 3-4 years so I'm very much a beginner. (if I remember rightly) Heisenberg liked to describe things in maths and Feynman preferred visual models, I'm swinging toward the Feynman camp. I've read a lot of literature that particles are not dimensionless points. Why can we not think of them as such? Why can particles not be points of energy in space which (depending on the amount of energy in the point) cause space to fold around them? Then it's more logical to see how they give rise to fermions and bosons depending on the nature of the folding and interaction between the folds. How do you visualise particles and their interactions?
