In Pythagoras' Trousers, science writer Margaret Wertheim offers an astute social and cultural history of physics, from ancient Greece to our own time. Wertheim demonstrates that from its inception, physics has been an overwhelmingly male-dominated activity and continues to be so today. But what, she asks, would the world look like - what could the world look like -if men and women worked side by side in shaping the physics of the future? Wertheim puts forward the startling hypothesis that gender inequity in physics is a result of the religious origins of the enterprise. Physics, she reveals, is a science based on a conception of God as a divine mathematical creator. For most of its history, it has been intimately entwined with the institutions of Christianity, and in line with those institutions has historically been closed to women. Furthermore, physicists' world picture has evolved from a deeply "masculine" perspective.
