How Graphics Cards Work"
The images you see on your monitor are made of tiny dots called pixels. At most common resolution settings, a screen displays over a million pixels, and the computer has to decide what to do with every one in order to create an image. To do this, it needs a translator -- something to take binary data from the CPU and turn it into a picture you can see. Unless a computer has graphics capability built into the motherboard, that translation takes place on the graphics card. A graphics card's job is complex, but its principles and components are easy to understand. In this article, we will look at the basic parts of a video card and what they do.

Choosing an E-Book Reader Scientists Have Simulated Time Travel With Photons Looks like time travel is possible... for particles of light. Using a photon, physicists have managed to simulate quantum particles traveling through time. Studying the photon’s behavior could help scientists understand some inexplicable aspects of modern physics. "The question of time travel features at the interface between two of our most successful yet incompatible physical theories -- Einstein's general relativity and quantum mechanics," University of Queensland’s Martin Ringbauer says in a news release. "Einstein's theory describes the world at the very large scale of stars and galaxies, while quantum mechanics is an excellent description of the world at the very small scale of atoms and molecules."
