"Magnetohydrodynamics, or MHD, is a branch of the science of the dynamics of matter moving in an electromagnetic field, especially where currents established in the matter by induction modify the field, so that the field and dynamics equations are coupled."

Besides giving away to charity, most rich people waste their money on boring, frivolous things such as yachts, diamonds, and mansions. Here's a rich English guy that knows how to have fun. I hope he does build a bigger one. I would like to see a flying double-decker bus.

"Canadians are not fully informed about these risks and may not be taking appropriate precautions to protect themselves," the report says. It's not that Ottawa hasn't identified toxins. In 2006, the government compiled a list of more than 4,300 toxic substances it was evaluating."

In a perfect world, you could enjoy great sound by installing just four full-range speakers - one in each corner of your car. In the real world, things aren't quite that easy. Full-ranges simply aren't up to the task of accurately reproducing the entire music spectrum. That's why top-notch systems employ two or more component speakers - like a woofer and tweeter - per channel. Each component is designed to reproduce a specific range of frequencies, and together they can cover the entire music spectrum accurately.\n\nA complication arises, however, since source components such as CD players deliver all of these frequencies - low, high, and in between - as a single music signal. This is where crossovers come in. A crossover divides the music signal into frequency bands that are compatible with the different types of component speakers.

Canadian author Watts (Starfish) explores the nature of consciousness in this stimulating hard SF novel, which combines riveting action with a fascinating alien environment. In the late 21st century, when something alien is discovered beyond the edge of the solar system, the spaceship Theseus sets out to make contact. Led by an enigmatic AI and a genetically engineered vampire, the crew includes a biologist who's more machine than human, a linguist with surgically induced multiple personality disorder, a professional soldier who's a pacifist, and Siri Keeton, a man with only half a brain. Keeton is virtually incapable of empathy, but he has a savant's ability to model and predict the actions of others without understanding them. Once the Theseus arrives at the gigantic and hideously dangerous alien artifact (which has tellingly self-named itself Rorschach), the crew must deal with beings who speak English fluently but who may, paradoxically, not even be sentient, at least as we understand the term. Watts puts a terrifying and original spin on the familiar alien contact story. (Oct.)\nCopyright © Reed Business Information, a division of Reed Elsevier Inc. All rights reserved.
