In my undergraduate physics cohort at university, there were TWO young women, but I know that's going back a bit. They were feted and prized and looked after. Guys would leap to their assistance if, for example, they couldn't get the oscilloscope to display but I suppose you'd call that mansplaining now. At the physics graduation dinner, one of them, whom I'm still in touch with, leapt out of a wheeled-in cake wearing a basque. I guess you'd call that something nasty now as well. My point is, that there was NO intimidation or discouragement offered to these ladies in fact the opposite but that's what I hear frequently. btw I had glandular fever for 6 weeks in the final year and the lady in the basque photocopied all her lecture notes for me. I got a good degree partly down to her.
