Everyone going through STEM needs to see the movie Hidden Figures for a variety of reasons, but one bit stands out as poignant: I believe it was Katherine Johnson, who is asked to calculate some rocket trajectory to determine the landing coordinates, thinks on it a bit and finally says, "Aha! Newton's method!" Then she runs down to the library to look up how to apply Newton's method. She had the conceptual tools to find a solution, but didn't have all the equations memorized. Having all the equations in short term memory only matters in a (somewhat pathological) school setting.
