I think we also need to show young women about science jobs outside of academia - I can never understand why so many STEM events concentrate on these, and non academic careers aren't highlighted. Especially as these may be the more family friendly long term.
I'm a physicist, on my first degree there were 90 in my year, 7 women (3 physics with music, 3 medical physics, 1 astrophysics). To my knowledge 3 of those women carried on in physics, none in academia.
In my job now, I travel the world working on the development and implementation of new radiotherapy techniques. I love what I do, and I'm proud to be a physicist. Even if people still think you might be booth totty!
