Physics of the Impossible - building a light sabre.

Extracts from this document...

Physics of the Impossible

      In Physics of the Impossible: A Scientific Exploration into the World of Phasers, Force Fields, Teleportation, and Time Travel, Kaku explains the real science behind some of our favorite technologies in science fiction, including time travel, teleportation, invisibility, alternate worlds, and more. He explains that some of the technologies we consider commonplace now, would have been considered impossible 150 years ago. And in the same sense many of the things we consider impossible today may become common place in the future.

   One topic he covers is light sabers, Aside from the sheer impracticality of this weapon  and not to mention how hazardous it would be to wave one of these around the Star Wars light saber will almost certainly never come to be. The first engineering challenge would be in figuring out a way to stop the beam of light about two feet from the source. Light simply does not work in this way, unless there's something to obstruct or absorb it.

    Many people use this theory to explain fluctuations in the stock market, they can do this because the theory behind Brownian motion is very close to being an equation which describes random motion (though naturally a perfect equation would be impossible), and fluctuations in stock market prices are very random.

    He made the discovery by putting what was suspected to be a positron source in a cloud chamber. The resultant image is above.
