What is Deep Simplification?
By deep simplification, we refer to strategies that allow a wider range of problems to be addressed and solved, via a conceptual framework that is algorithmically simpler than the one used at present.
Some strategies simplify by restricting the range of problems or audience they work with. For example, one “un-deep” simplification common to intro-physics classes is the use of range equations, rather than acceleration integrals, to solve trajectory problems. You simply plug and chug, but severely restrict problems you can solve.
