I like the concept but not the execution. The student doesn't find out
what properties of various data structures and mathematical objects
are fundamental. There is too much of the old style of telling
students what to learn, and neither explaining why nor allowing
students to discover. I find it annoying that the book gives complex
number examples, but shies away from actually using complex
arithmetic. Far more CS could be introduced at the level of the math
being used.

The book uses Python, but none of the very capable math software
available beyond graphing calculators. I prefer Ken Iverson's
approach, in which he taught how to write programs to do algebraic
manipulations and symbolic differentiation.

Does anybody know these authors? Can we engage them in a process to
improve what they have done?
