...whizziest new device, an ultrafast form of computer scanning called electron-beam computer tomography (EBCT), picks up the presence of tiny deposits of calcium in the heart. One study based on the scan showed that patients who build up 20% or more calcium each year have an 18-fold greater chance of suffering a heart attack than those with less calcium in their hearts...
...MOLECULAR AND DOT COMPUTERS Other exotic designs include the molecular computer and the quantum dot computer (which replace the silicon transistor with a single molecule and a single electron, respectively). But these approaches face formidable technical problems, such as mass-producing atomic wires and insulators. No viable prototypes yet exist...
...screen swirls with zippy images: a cocktail tumbler that mysteriously waddles on an airplane meal tray, a Tinker Bell electron that darts through our hero's thoughts, a vortex of digital effects that suck you into cyberworld, and a few Fellini moments, like the tunnel full of empty cars and the ghostly accordionist on a picturesquely creepy streetscape...
...have to go to a theater to see these apparitions. In fact, you can't. Quantum Project, a 32-min. epic about a physicist (perpetual star-of-the-future Stephen Dorff) who defies his Merlinish dad (blustery John Cleese) to find love with the proper electron (petrochemical-sunset-haired Fay Masterson), is the first medium-length, Hollywood-style movie made uniquely for the Internet. Just log on to sightsound.com as the Web faithful did at 12:01 a.m., Friday, when Quantum popped online. Pay $3.95 to rent or $5.95 to buy. Download for four minutes--or many hours...
...laws of physics permit time travel, even in principle? They may in the subatomic world. A positron (the antiparticle associated with the electron) can be considered to be an electron going backward in time. Thus, if we create an electron-positron pair and the positron later annihilates in a collision with another, different electron, we could view this as a single electron executing a zigzag, N-shaped path through time: forward in time as an electron, then backward in time as a positron, then forward in time again as an electron...
