I don't really care if the folks that designed the aircraft I'm flying in knows anything about history, social studies, or if he/she would do well at a cocktail party. I DO care if they know about Solid Mechanics, Fluid Mechanic, Thermodynamics and such. Getting me safely from New York to LA is really all I care about. And that is a matter of Physics and Calculus and all the rest... not the abiity to be "well rounded".
