The process is not simple but can be defined through a few key concepts: Spinning mirrors, high-speed DLP Projections, and very precise math that figures out the correct axial perspective needed for a 360-degree image (even taking into account a viewer's positioning.)

Armed with a trusty axe, killer riffs, and a ton of attitude, the guitar-wielding bard is the second hero class to be introduced in the upcoming Wrath of the Lich King expansion for World of Warcraft.

With careful training a person can send nerve signals to their vocal cords without making a sound. These signals are picked up by the neckband and relayed wirelessly to a computer that converts them into words spoken by a computerised voice.

A new look at the trajectories for various spacecraft as they fly past the Earth finds in each case a tiny amount of surplus velocity. For craft that pursue a path mostly symmetrical with respect to the equator, the effect is minimal. For craft that pursue a more unsymmetrical path, the effect is larger

In 2009, ONR will decide whether to award contracts for deployment to BAE Systems PLC (Farnborough, U.K.) or General Atomics Technologies Inc. (San Diego) for the railgun. Boeing Co. (Chicago) and Charles Stark Draper Laboratory (Cambridge, Mass.) are vying for the projectile contract. If the Navy decides to deploy the railgun, it plans to have a final design in place for approval by 2012. Initial prototypes will probably shoot a single projectile, but plans for rapid-fire versions are already on the drawing board. The final design specification calls for a muzzle velocity of 5,760 mph for a weapon that is capable of launching a projectile in a parabolic ballistic path 94 miles high. It must strike targets within six minutes at 3,840 mph.
