Clearly written proofs, Sep 22 2002

I was a Computer Engineering student who wanted to learn Galois Theory. So I took a 3rd year pure math course in Abstract Algebra. The instructor used a different text book. I found it hard to follow the proofs in that book. Later I discovered Hernstein book in the library and it saved me. The proofs are very well written in Hernstein's book.

Excellent Textbook with lots of examples, July 31 2002

I used this book for self study of Mathematical Logic with the aim of understanding Godel's incompleteness theorem. I also referred to other introductory Mathematical Logic books. In my opinion, this book is by far the best among them. Very readable and contains lots of carefully selected examples.

The way to write books!, April 20 2001

I used this book for two courses that I taught: One was for a graduate course at Carnegie-Mellon University and the other was for a group of Software Engineers in a startup company. The students in both setting overwhelmingly liked this book. I carefully considered about dozen books before selecting this book. The organization of the book is very logical and makes even the difficult concept very simple for the students to understand. This is the way to write computer networks textbooks.
