Hi Patrick, Welcome to the list! When I was a student a friend told me about transfinite induction. While ordinary induction allows you to generalize from n to n + 1 and thus to a countable set, transfinite induction enables you to explore the continuum.
He didn't explain how it was done, though. I learned later while following a functional analyses class. Saibal > > I know this one! > > I had a friend who published a magazine called "Zorn" printed on pale > yellow paper... ;) > > Paddy Leahy >
