Three academics The first, René, a mathematician, arrives at Cambridge to complete a PhD but is desperate to keep his real intentions for study a secret. The second, Ruth, René's supervisor, eager to rise through the ranks of the university. The third, Diego, Ruth's husband, and a philosophy lecturer trying to save his department from budget cuts. All is well, until René begins an affair with Ruth and then with Diego.

Compressing an enormous amount of information--over 400 studies--into a readable, engaging account suitable for parents, educators, and policymakers, this book advances the debate about women in science unlike any other book before it. Bringing together important research from such diverse fields as endocrinology, economics, sociology, education, genetics, and psychology, the authors show that two factors--the parenting choices women (but not men) have to make, and the tendency of women to choose people-oriented fields like medicine--largely account for the under-representation of women in the hard sciences.

Dabble in the beauty and wonder of mathematics as it contributes to a variety of fields including literature, biology, economics and of course psychology, where the mathematics of sex plays some unexpected roles.

At what point in your dating life should you settle down?"--Amazon.com.
