the hero solved the problem of controlling a supersonic airplane by reversing the flight controls.
Yes, that's right, he detonates torpedoes by reversing the polarity of his radio.

Batman: The Movie (1966): "If I could just.The 2007 Oceans Thirteen had Brad Pitt dismissing Don Cheadle's technobabble by saying, "Becomes magnetized, reverse polarization, I know.".They inverted their shield polarity, which caused the missiles to lose the lock and miss the ship. The trope is then subverted because, despite the missiles flying straight through said beam, it has absolutely no effect whatsoever. The original 80s Transformers movie: Being pursued by heat seeking missiles, the fleeing heroes reverse polarities, which apparently causes a sorta energy beam to appear beneath their spaceship.Evil, having turned good, does reverse the polarity, the beam destroys the asteroid instead of sending it to Earth. Evil to pull an asteroid to Earth has "Do not reverse polarity" written on a low-tech-looking panel. In Austin Powers in Goldmember, the tractor beam used by Goldmember and Dr.Used to defeat energy-eating giant square stompy robot in Kurt Neumann's 1957 Sci Fi film Kronos, Destroyer of the Universe.Also see Techno Babble and Revive Kills Zombie.Ĭompare to Now Do It Again Backwards and Tim Taylor Technology.
However, if the neutrons are flowing somewhere, reversing the polarity might refer to changing the direction of flow.Ĭlosely related to the Forgotten Superweapon. Of course you can't do this with neutrons, because they're as electrically neutral as the name suggests, although if we're getting technical, they do have a magnetic polarity. How hard can it possibly be to remember?" Reversing the polarity on a car is also possible-some vintage cars, particularly British ones are positive-ground while negative-ground has been the standard worldwide since The Sixties, so if you want to put a modern MP3-compatible stereo in your '59 Morris Minor a car polarity swap is a must.īesides, it makes the characters in question look a lot less like brilliant scientists when they are (basically) sighing and asking the technician, "Did you plug it in the wrong way again? I mean, seriously. This is why most "complex" devices nowadays are equipped with diodes, which keep the current from flowing backwards if the polarity is reversed, preventing damage to the main circuitry. Most simple powered toy vehicles, electric toothbrushes and other devices that rely on a spinning electric motor will simply run backwards while more complex electronics with a DC power supply may even break or fry the device in question. Doesn't quite have the same effect, though. Of course, you can "reverse the polarity" in real life - just put the battery in the other way round. we could reverse the polarity of the positron toilet and send a stream of charged crap particles toward the Romulans, rather than away."). Usually only thought of at the very end of the show ("Captain. The version most associated with the Third Doctor is "reverse the polarity of the neutron flow", although he only said it once during his time as the Doctor.Ī type of Applied Phlebotinum, Reversing the Polarity is the be-all end-all technical solution for any problem.
However, it was popularized by Doctor Who, as Jon Pertwee asked the writers for a simple piece of Techno Babble he could reliably deliver. In reality, the phrase "Reverse the Polarity" can be traced back at least as far back as a Carl Barks comic in March 1961, and as mentioned below, Forbidden Planet in 1956 had "Stand by to reverse polarity" as an apparently standard procedure when landing the starship. Urban legend has it the expression originated on Doctor Who. It seems that every futuristic gadget or space ship subsystem performs some miraculous function if only you route the power through it backwards. When a major obstacle in a Science Fiction show is resolved purely through the judicious application of Techno Babble, the characters have successfully Reversed the Polarity.
