# Book Recommendation "What is Mathematics?"

*What is Mathematics* is a classic, lucidly written survey of mathematics by Courant and Robbins. The first edition was published in 1941! I have only read a portion of it, mainly the chapter on calculus. One page of Courant is worth about five pages of my old college calculus textbook, and it’s a lot more fun to read.

The reader of this book should already be familiar with algebra and trigonometry. For engineers, some worthwhile sections of the book are:

Chapter 2, section 5, Complex Numbers.

Chapter 6, Functions and Limits.

Chapter 8, The Calculus.

As the author states, “… Chapters VI and VIII together form a self-contained presentation of the calculus with emphasis on understanding rather than routine”. The book does not discuss linear algebra. Chapters 1 – 8 are a reproduction of the 1947 edition, while Chapter 9, Recent Developments, was written by Ian Stewart for this 1996 edition. The book is available new in paperback from Amazon and other outlets.

Richard Courant and Herbert Robbins, *What is Mathematics? An Elementary Approach to Ideas and Methods*, 2^{nd} Edition, Oxford University Press, 1996.

Courant also wrote a textbook, *Introduction to Calculus and Analysis*.

Indeed, such are available.

Regarding the book; "In the sixty years during which Courant and Robbins, as the book is often called, has been in print, several distinguished scholars have had the opportunity to sing its praises. Reviewing the first edition, E. T. Bell described the work as “inspirational collateral reading.” Hermann Weyl thought it “a work of high perfection.” For Marston Morse it was simply “a work of art.” Even Albert Einstein chimed in with high praise."

Rick,

Thanks for this interesting book review from 2001. The book was sixty years old then. I hope it will still be in print in another 21 years!

Neil

Thanks Rick

Gee, of all the distinguished comments, I'm almost embarrassed to add my 10 cents worth :)

Thanks for the review and for introducing me to, yet another, fine work. Only 10 dollars in eBook format on Amazon. I tend to read exclusively in soft copy these days due to the rather large footprint my bookshelf occupies in my house (a large portion of that are the various editions of my favorite book, "Understanding Digital Signal Processing", Rick Lyons :) - Sorry Rick, couldn't resist... but I digress. The $10 is well worth the review and refresh provided.

You're welcome!
