An Introduction to Modern Numerical Analysis

Revised 26/05/09

Abstract. Lists, challenges and competitions have a long and primarily lustrous history in mathematics. Consider the Hilbert and the Millennium problems. This is the story of a recent highly successful challenge. The book under discussion also makes it clear that with the continued advance of computing power and accessibility, the view that “real mathematicians don't compute” has little traction, especially for a newer generation of mathematicians who may readily take advantage of the maturation of computational packages such as Maple, Mathematica and Matlab.
