Strange that the author starts with a book that began as an online, runnable, interactive book. (Taking a lot more than a week to write.)

Presumably he would end up with a library of functions that somehow capture some of the mathematical models found in some books. Without any of the understanding of what they mean or how to apply them, this is meaningless.

If you really want to do something meaningful and ambitious, spend a year trying to write a program that can understand a single sentence.
