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. The modern ménage a trois explodes gender, love and sex and, using the lens of geometry, reveals equal relationships are indivisible by three.

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.
