And now someone's having a go at people who chose to become geologists? Seriously - the level of numeracy required to be mining geologist won't get you far in astrophysics. Why don't you take a shot at us geophysicists instead!
When I was a postgrad I shared a floor in the physics dept with the theoretical physics guys - easily the smartest people on campus. Yet thanks to the absolute lack of commercial application of their research, these guys will never be earning even average salaries. Society pays its sportstars good money, so we need to work out how to make astrophysics a spectator sport. By encouraging more lay people to get involved the pros are doing their best to make it more palatable to divert the required money into a Great Purpose- like finally putting all those silly dark 'whatever' theories to bed....
