Professor Athene Donald of Churchill College, Cambridge, a renowned physicist and former University of Cambridge Gender Equality Champion, tackles this persistent problem of the lack of women in science, and in particular physics and engineering, in her lively, provocative new book ‘Not Just For The Boys’ (OUP, £16.99, ISBN 9780192893406).
