Is it even possible? Or am I just flat out wrong once again!?! Whenever I really need to procrastinate, I turn to writing a calculus book. In this case.. For about three days I pursued the problem of whether or not you can teach topology before "rigorous Calculus". Is it even possible, to teach topology before rigorous Calculus (i.e. the Calculus that requires proof but is usually not yet called "Analysis") In the end, the following two paragraphs is pretty much the fruit of my 3 days of effort, and is probably either a) wrong, or b) written somewhere else. Writing a book is hard!
