# Reading "Concrete Mathematics": Intro

### What's it all about

The following texts are the *free-style notes* I am writing along with reading
the book Concrete Mathematics (2nd edition) by
the authors **Ronald L. Graham**, **Donald E. Knuth**, and **Oren Patashnik**.

### Expectations

I expect this book may be tough for reading and understanding because this is
the type of comment I had met about it. One of the co-authors of
Concrete Mathematics is **Donald Knuth**, known for
the Art of Computer Programming: a foundational
computer science work, not the easiest one to comprehend, especially for a
non-prepared reader. So I expect that even a more basic book co-authored with
**D. Knuth** would require effort to get through. Especially I'm dreading the
exercises!

On the other side, mathematics fascinates me. If the book's prerequisites aren't
**too** demanding, I hope to find *thought-treasures* in it.

## Preface

Hmm, so, according to the preface, it looks like Concrete
Mathematics and the lectures it was born from cover the topics
I'm more accustomed to being called *discrete mathematics* (but with a tint of
continuity). And this sounds like really good news since I had spent my share of
time digging into this domain.

Hopefully, this would make Concrete Mathematics
more approachable for me and even, as promised by the authors, make it
a tale of mathematical beauty and surprise

.

From the typography perspective, I'd like to praise a chic approach to providing citations and side-notes. They're located in the margins beside the main body of text, enriching and savoring it.

Aha! Here it is, the most horrifying truth is revealed closer to the end of the
preface: This book contains more than 500 exercises

.
This is going to be a bumpy ride for sure ðŸŽ¢
