"Let's put it this way: I have a tenuous grasp of category theory and am completely lost when it comes to topos theory. Now I think back to myself at age 13, just learning about things like calculus. Just as I needed a way in then, I need a way in for these other topics. It would be useful for many articles to have a header saying (for example, for integral):

Do this to enough articles, and we will have a mathematics road map for self-study. The Anome

This is a really cool idea. It would help prevent reiteration of all the prerequisite knowledge in specialized articles, and provide a nice path towards learning difficult stuff. Something like this may even be useful for non-mathematical subjects as well -- certainly the other science articles (physics, chemistry, biology, etc.) would benefit from it, but it could even be applied to articles on history, politics, psychology, or anything else where a foundation of terminology and concepts is necessary in understanding the more complex ideas presented in specialized parts of those subjects. At the very least, some form of "Introduction to terminology" or "Glossary of notations" and the like would be helpful. -- Wapcaplet 12:26 25 Jun 2003 (UTC)"

Also, for another "roadmap" idea, see fractional calculus:

mathematics -> fractional calculus -> differintegral
