But when he went on to study a good first-year book from Cal Tech, he discovered he did not know physics. The early book was actually an impediment to his work. If you teach the problem of an apple falling from a tree, you can present the formula for calculating the time it takes for the apple to fall. This requires only simple math. But this does not teach you what acceleration really is.
Acceleration is the second derivative of position with respect to time.
More importantly, physics is not the memorization of specialized formulas. This is wrong. Actually, electrons are distributed around the nucleus in accordance with a probability density equation. The electron even has a probability of being inside the nucleus at any one time. We have many children and now adults thinking that electrons orbit atomic nuclei like planets.
