Yeah. I believe if one really understands something, one can describe
it in two or three sentences in English. One who struggles with pages of
math does not know a thing; and those formulas can be forgotten easily.
In real work, what is important is good intuition, simple calculation, and
the idea of the orders of magnitude. Seldom is there time to play with
