Words fail to express what a big deal this is to physics!!!!!!!!
I think I understand how this is a big deal in physics.
I don't 'get' :
"In two dimensions, the loop cannot shrink, to a point so the particle is not as constrained"
. . . if the particle don't get 'stuck' in 3D why do they in 2D ?
@TheMiddleWay . . . I saw that, still didn't make sense
@TheMiddleWay . . . wonderful explanation, thx
