Throughout most of its history, Chevrolet has made the right moves at the right time. To follow the Stovebolt, division general manager William "Big Bill" Knudsen and GM design director Harley Earl cooked up an elegant line of Cadillac-style cars for 1929-32. The 1930-31 line comprised a single series offering roadsters for two or four passengers, a phaeton, three coupes, and two sedans. Prices were attractively low: $495-$685. The 1930-33 Chevys carried a different series name each year: in order, Universal, Independence, Confederate, then Eagle (deluxe) and Mercury (standard). This practice was ended for 1934, when models were grouped into Master and Standard lines. Master tacked on the "DeLuxe" handle for '35, and Standards became Masters for 1937-39. The '33s, with their skirted fenders and graceful lines, were perhaps the most-attractive Chevrolets of the decade. Body styles proliferated, and by 1932 included such exotics as a $625 landau phaeton. The 1933 Eagles offered many features designed to win buyers from Ford: a Fisher body with "No-Draft Ventilation" front-door ventwing windows, airplane-type instruments, Cadillac-style hood doors, a cowl vent, synchromesh transmission, selective free-wheeling, safety plate glass, adjustable driver's seat, even an octane selector. Laparoscopic surgeons operate on colons, gall bladders and almost anything that can be accessed by a small incision. But they never put their hands inside the patient. Instead, they use robotic controls -- essentially a joystick -- to move instruments inserted into the patient through a tiny incision (it's sometimes referred to as a "keyhole surgery"). They watch what they're doing on a video screen. The ability to make an instantaneous connection between hand motion and remote movement viewed on a screen is crucial, because laparoscopic surgeons don't look at their hands. Their hands are moving joystick controls, not scalpels. As luck would have it, that ability is also the mark of a great gamer. The recent study bears out this correlation. First, they played three non-medical video games, including Super Monkey Ball, for 25 minutes. Next, they completed a wide variety of virtual laparoscopic surgery techniques. The researchers measured their accuracy. Their completion time in both parts. lil peep
