Why are there so few prominent female physicists? Traditionally women have faced barriers in higher education, denying them access to higher learning and scientific laboratories. Today many of these barriers have been breached, but the female pioneers who overcame discrimination and became major players in their fields remain largely in the shadows. Their names deserve to be known and the importance of their work, achievements and contributions to science warrant recognition. Originally published in 2006, Out of the Shadows provides an accurate and authoritative description of the women who made original and important contributions to physics in the twentieth century, documenting their major discoveries and putting their work into its historical context. Each chapter concentrates on a different woman, and is written by a physicist with considerable experience in their field. The book is an ideal reference for anyone with an interest in science and social history.
