I counted seventy one (!) factual errors by the time I got to the section on the Leslie Speaker, where "rotating motors" become "horns" that are "picked up" by speakers. That makes two PhD students today on the front page of Hacker News who are talking straight out their asses. This entire article bums me out. If you see a scathing editorial printed in The Atlantic (you won't -- editors NEVER correct the really bad articles like this one) that's me. "... motors (essentially two electromechanical horns) that had been rotated to create a Doppler-effect-based vibrato. These horns were, in turn, picked up by the dual speaker units."
