The first author is well known for teaching "wild ride" undergraduate classes where he compensates by spending a lot of time on their pedagogy.

He once taught an open to all freshman knot theory elective:

I also remember taking a class on vector calculus from the same author... which detoured through rudimentary manifold theory and differential forms, and ended with a final week on de Rham cohomology and the Mayer-Vietoris theorem (on vector spaces, to be fair, and not modules in general.)

(And is a very fine K-theorist, too, if I say so myself.)

So, just from the contents ... does anything make this especially different from other discrete math books?
