James Doohan, who played Chief Engineer Montgomery Scott on the TV series Star Trek, has died at the age of 85. Star Trek and the writings of Isaac Asimov triggered my love of science fiction, a love I have not yet outgrown. Doohan’s character, a Scotsman commanding vast arrays of knobs, buttons, switches, and blinking lights, made engineering look like a glorious profession. He is undoubtedly one of the reasons I journeyed down that career path. Engines at warp speed, Mister Scott!
