I find Bob's outburst very patronising. But I'll add that over the years it has become obvious how little science they teach in schools thesedays. I've had new PhD students MSc who don't know how to make a 1 Molar solution. That used to be in the GCSE Chemistry "in my day", ditto the "A" Level so everyone took it for granted. Not knowing stuff like that is not the fault of students if they've not been taught it.
....and one last little point from me to Bob. "Knowledge of the real world" gets you knowhere in academia. Believe me, it's an odd world where the blind lead the blind and fools become kings (mixing metaphors). No amount of life experience will get you a grant. Infact, very often, no amount of science will either. Ahhh the ramblings of an embittered academic. Please ignore me, for I jest!
