Calculus of Happiness

“Brilliant. . . . Where Fernandez’s book scores highly is that it goes beyond being a typical self-help manual for the numerate, by presenting example after example of how mathematical topics such as probability, game theory and exponential functions really do make sense of a world that can sometimes seem so subjective. It’s also an easy-going analysis of those areas in life that get brushed under the carpet, to be attended to another day. Once you realise it all boils down to maths, you will wake up happier, wealthier and healthier tomorrow morning, and we have Oscar E. Fernandez to thank for that.” Nick Smith, Engineering & Technology (full review here)

“Surveys a wide variety of ways that mathematics can be used to improve decision making and general well-being. . . . [Fernandez] believes that even a smidgeon of algebra can encapsulate a lot of wisdom.”TIME.com

“I absolutely love this book. The mathematics described is beautiful and accessible and, most important of all, truly meaningful and relevant.”         –James Tanton, author of Without Words: Mathematical Puzzles to Confound and Delight

“[E]ngaging. . . . Readers are sure to get a sense of how content from algebra and precalculus can help inform us about important decisions that are almost universally relevant.”–Jason M. Graham, MAA Reviews

“With its appealing informal style, choice of topics inspired by everyday life, and links to the relevant mathematical concepts and methods, this book shows how mathematics can improve one’s quality of life. From healthy eating to managing the monthly budget, readers will look at their daily activities from an angle they may have never thought of.” –Max Alekseyev, The George Washington University
