Although this pronunciation of " gigawatt " was once considered the correct one, it is no longer the most common. In addition, since Robert Zemeckis and Bob Gale were unfamiliar with the term, they misspelled it in the script. Because of this, a "jigowatt" will sometimes be referred to on internet forums as a fictional unit or to make fun of someone's electrical knowledge. The spelling "jigowatt" is used in the novelizations of the second and third films.
However, George Gipe 's novelization of the original film uses the correct spelling "gigawatt". The phrase "flux capacitor" has appeared in more serious contexts.
Patent 6,, describes a "lateral flux capacitor having fractal-shaped perimeters", the idea being to make a capacitor in an integrated circuit , some of whose capacitance exists between two conductors on a single layer hence, "lateral". The device is not a lateral flux-capacitor but a lateral-flux capacitor. Flux is commonly used in electronics and electromagnetic theory and application, but rarely in the context of a capacitor.
In general terms, flux simply means the rate at which some quantity such as electric charge passes through a surface e. It is speculated that the movie terminology is used fictitiously to represent a new and unknown type of flux. The Fluxus art community commonly used "Flux" to designate various items and products it was associated with. There was even a Flux Mass, a parody of the Catholic mass. The art community adopted the term "Fluxus", meaning "flow" or "fluid", implying "change", because it wanted to distinguish itself from earlier forms of Dadaism, and because it was new at the time.

Flux capacitor. View source. History Talk 2. The flux capacitor in the DeLorean. But at a microscopic level, the story is not that clear. The collision of two billiard balls looks pretty similar in reverse; even more so for the collision of two atoms. A beam of light travelling in one direction obeys exactly the same laws of physics as a beam of light travelling in the opposite direction. Indeed, the basic equations of physics look essentially the same if we replace time with its negative.
This mathematical transformation reverses the flow of time in our equations. Since the microscopic laws of physics appear to be unchanged under this mathematical transformation, we say the universe possesses time reversal symmetry, even though we cannot actually reverse time in reality.
There is a conceptual conflict here. At the macroscopic scale, the entropy of the universe — a measure of disorder or randomness — always increases, so that there is an arrow of time. This is obvious in our everyday experience: a scrambled egg is not reversible. How does this irreversiblity emerge from microscopic laws that are reversible?
This remains a mystery. Microscopic reversibility presents an important technological challenge. It complicates the diversion of electronic and radio signals around a circuit. There are various applications where engineers want electromagnetic signals such as light or radio waves in a circuit to behave a bit like cars around a roundabout. This is pictured below: a signal entering port A of the device should be directed to port B ; a signal entering at B should go to port C ; and a signal entering port C should be directed to port A , clockwise around the device.
One way to do this is to use a network of amplifiers to switch signals as desired. The scientists, who published their research in Physical Review Letters, have proposed two different potential circuits -- one of them borrows the design of the three-pointed flux capacitor Doc Brown and Marty McFly used to travel to and in their DeLorean.
The circulator, according to the Center for Future Low-Energy Electronics Technologies which was involved in the study , "uses the quantum tunneling of magnetic flux around a capacitor, breaking time-reversal symmetry. As such, the proposed device will be a boon for quantum computing, where researchers need to direct signals with precision.
What, you might ask, is really the point if you can't go make a bunch of bets on sporting events that have already happened? In addition to paving the way for quantum computing, this technology can lead to better radar as well as improved WiFi and mobile antennas. Maybe that's not quite as exciting as time travel or even power-lacing shoes. However, it sure beats getting your dad to beat you up while you make a move on your mom.
