Girls, if you enjoy science, go for it!

The problem we face in this country is a lack of females at every level in the physical sciences. Where I teach – the maths faculty at the University of Cambridge – we  see the problem acutely. From undergraduates (less than  20 per cent) to PhD students (25 per cent) and as for academic staff – they can be counted on one hand. The lack of females  is a serious problem facing the UK, and a waste of valuable resources.
