since graduating from college (5 years ago). Today I had trouble remembering the limit definition of the derivative. To think I was studying Hilbert Spaces and logic my final year in college. If you don't use it you lose it. Come to think of it, I don't remember much from DiffEqs either. I mean I could relearn it easily, but it is kind of depressing to ace that stuff and now barely remember a lot of it.
