>I don’t understand them. You need three separate PhDs in functional analysis, algebraic topology, and Lie theory to even begin understanding linear differential equations. And we have no idea how to solve non-linear ones. Chaos theory proved to be garbage, numerical methods aren’t very enlightening, and proving uniqueness and existence for just one class of non-linear diffeqs is a Millennium Prize problem.
