If you steelman the author's claim, the unsaid interpretation is, the optimal way of learning Physics is to solve questions. Lots of them. On the order of thousands for an undergrad Physics curriculum. Reading the textbook and getting some concepts out is only a precursor to real understanding which is when you apply those concepts to scenarios in questions. Far too many people get stuck thinking reading the book and highlighting is sufficient, but it is only the foreplay not real sex.
