- Actually, I don't mind the abstraction as long as its accompanied with some
- explanation and motivation of the ideas leading up to it. This motivation
- doesn't necessarily have to take the form of examples but can be more in the
- way of a historical account of the evolving thought processes that led up to
- the abstraction. Either way works for me.
-
- Normally, one would get this kind of context (I would hope) in a class. I was
- just trying to learn enough about this subject so that I could understand the
- main ideas of an intriguing paper I ran across. I was just using a couple of
- math dictionaries which don't provide a lot of context.
