This innovative interdisciplinary collection confronts the worldwide challenge of women's under-representation in science through an interrogation of the field of physics and its gender imbalance. Leading physicists and sociologists from across Europe collaborate to adopt a comparative approach. They draw on theoretical perspectives and empirical evidence to explore the reasons behind low participation levels, from entering the field to sustaining a career, emphasising the importance of social perspectives over biological explanations. Evaluating policy solutions implemented in various European contexts, this book offers key insights into the world of women physicists and sheds light on their life stories.
