"There is the satisfaction of watching a figment of the imagination emerge through the aid of science to a plan on paper.  Then it moves to realization in stone or metal or energy...Then it elevates the standard of living and adds to the comforts of life.  This is the engineer's high privilege."

-Herbert Hoover
