In The Language of Mathematics, Keith Devlin reveals the vital role mathematics plays in our eternal quest to understand who we are and the world we live in. More than just the study of numbers, mathematics provides us with the eyes to recognize and describe the hidden patterns of life-patterns that exist in the physical, biological, and social worlds without, and the realm of ideas and thoughts within. Taking the reader on a wondrous journey through the invisible universe that surrounds us - a universe made visible by mathematics - Devlin shows us what keeps a jumbo jet in the air, explains how we are able to view a football game on TV, and describes the mathematics that allow us to predict the weather, the behavior of the stock market, and the outcomes of elections.
