Navy Railgun

The railgun takes its name from the two highly-conductive and electrically charged rails that form an electric circuit once a projectile is loaded.http://www.technologyreview.com/Infotech/20164/?nlid=857&a=f Unlike an explosion using gunpowder, the railgun uses these electromagnetic currents to accelerate its non-explosive projectiles. By being sent through several electrically charged parallel rails, the railgun's projectiles are accelerated to several times the speed of sound, up to Mach 7.http://www.foxnews.com/scitech/2010/12/10/navy-railgun-shoots-bullets-electromagnet/

The weapon's design allows it to fire at two to three times the velocity of the navy's conventional weapons, allowing it to hit a target within 6 minutes. The railgun also has a longer range than the navy's conventional weapons, currently being able to fire up to 100 miles. The navy hopes to achieve the even higher range of 200 miles and pinpoint accuracy at this range through GPS technology.http://www.foxnews.com/scitech/2010/12/10/navy-railgun-shoots-bullets-electromagnet/

How to Become a Rocket Scientist

If you decide to choose rocket science as your career choice, you may be happy to find that there is actually a shortage of qualified scientists. The number of science and engineering majors in universities is dropping, which means you should have few problems finding work.

You may apply at NASA, work for the military, or get a job with a private company such as Lockheed Martin. Contact your school's career center for job placement assistance.

Space Pen

There is an urban legend that NASA spent millions of dollars in development to make the Space Pen while Russian cosmonauts simply used a pencil. Actually they both used pencils to begin with. http://history.nasa.gov/spacepen.html Project Gemini in fact used pencils. But do to the dangers presented by a broken pencil tip floating around the cabin in zero gravity it was decided that the Space Pen was a better option by both countries’ space programs.

Giant Vortex Cannon

In a clip from the BBC series Bang Goes the Theory, a large gun fires a vortex of air at houses made of straw, sticks and, finally, bricks, causing them to collapse. The "cannon" produces a 200 mph cloud of air that can be aimed at used as a weapon.
