" Many scientists (the most notable being Albert Einstein) think in visual, spatial, and physical images rather than in mathematical terms and words. (N.B.: That the theoretical physicist, Stephen Hawking, used an arboreal term to picture the cosmos [i.e., affirming that the universe "could have different branches,"] is a tribute to his [very visual] primate brain.)
