About five years is all that it takes for physics to morph from the concrete to the abstract. In ninth grade, students roll balls down incline planes to demonstrate Newton’s laws governing motion. By freshman year of college, those same young people are grappling with the insane-seeming mathematical implications of modern physics, with light acting as particle and wave simultaneously and with particles popping into existence and evaporating just as quickly.
The more physicists discover about our universe, the more esoteric it gets, and this tendency has bolstered the ranks of “outsider physicists’’ - people, mostly with no formal training in physics, who develop their own theories, only to see them languish in obscurity, ignored by the establishment.
