Will do, thanks.
There are so many interesting engineers and scientists out there that
shaped our world, and yet when I was at school all we learned about
were long dead kings that apparently did nothing but order wars.
You'd think they'd teach young engineers about those people they can
identify with, but I guess that's too much to ask when your gym
teacher also does history, and has the intelligence of a true
sportsman.
