I am aware of what they do...I was using it metaphorically, the same way Laura Ingraham uses it when she says "Shut Up and Sing" when referring to hollywood types.
It is a shorthand for "Do what you are good at, trained to do, expected to do, and paid to do, and don't use it as your platform for spouting off your personal feelings and opinions about things you might not have any expertise at."
BTW, I read Feynman's book "Surely You're Joking, Mr. Feynman", and I found it extraordinarily entertaining. The guy is a certified genius, and a certified nutcake...both coexisting quite nicely in one body!
okie dokie, got it.
You're right,his first book was hilarious. His 2nd book was about being on the (first) shuttle accident investigation. Not as good of a read but still worth it. I think I heard that Feynman died a short while back.
I used his practical joke about solving the rubber band around the wrist thing... worked pretty well. I especially liked how he got honors in English by writing (not even very well) about currents, eddies and vorices around wingtips, which was redundant. But the judges didn't know what he was talking about and couldn't take issue with it, whereas the guys busting their butts writing about points of literary minutiae were ripped apart by the judges & didn't even score honors... I guess they had baloney in education even back then.
