Feynmanian

Adjective, after the nobel-prize winning physicist Richard Feynman

Feynmanian thinking is a simplified way of thinking about a problem involving difficult mathematics in a manner that is still correct and accurate, whilst being very easy to explain to students. Feynmanian methods are often quite extraordinary and funny (both in the sense of being strange and comical).

The question then is, of course, how does e_r vary? Trying then to apply some Feynmanian thinking, let’s imagine the charge is moving in some way and we’re observing it from far away as a ”little dot” that moves around. But actually, we wouldn’t be seeing it as it moves now at time t, but rather as it moved at the delayed, or retarded, time t'=t-r/c, where r is
the retarded distance to the charge at time t'.
