Physics of the Impossible - building a light sabre.
Frank Fairechio 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. A physicists Slow Speed of Light what can be a break threw on stoping light at a point (4) Light, which normally travels the 240,000 miles from the Moon to Earth in less than two seconds, has been slowed to the speed of a minivan in rush-hour traffic -- 38 miles an hour. An entirely new state of matter, first observed four years ago, has made this possible. When atoms become
Mobile Phones
Mobile Phones I am investigating 3 rates of charges for people using mobile phones. Scheme 1: A payment of £15 per month for the line rental, plus 50p per minute for each call made Scheme 2: A payment of £24 per month for the line rental, plus 20p per minute for each call made Scheme 3: A payment of £31 per month for the line rental, plus 10p per minute for each call made. I am going to investigate which scheme is best for people using mobile phones. I will also vary the line rental, vary the cost of each call, make comparisons, and make generalisations. I will show graphs, tables and a conclusion to my investigation. Scheme 1: A payment of £15 per month for the line rental, plus 50p per minute for each call made.
