Blindsight by Peter Watts - 0 views

  •  
    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.

BBC NEWS | Technology | 'Magnetic electricity' discovered - 0 views

  •  
    In September this year, two research groups independently reported the existence of monopoles - "particles" which carry an overall magnetic charge. But they exist only in the spin ice crystals. These crystals are made up of pyramids of charged atoms, or ions, arranged in such a way that when cooled to exceptionally low temperatures, the materials show tiny, discrete packets of magnetic charge.
