The Art of Computer Science is a multiple volume book that Donald Knuth has taken upon himself to complete one day. Heās been working on it for decades and heās still not finished. The fact that the unwritten volumes contains stuff Iāve heard about suggests what a vast field he has chosen to cover. Even the list of chapters on Wikipedia is a little bit overwhelming.
āComputer scienceā is about as specific a term as āmathematicsā. Not even the top mathematicians are experts in every branch.
