摘要:

Particle theorists David Gross, David Politzer, and Frank Wilczek have been awarded this year's Nobel Prize in Physics “for the discovery of asymptotic freedom in the theory of the strong interactions.” The laureates are, respectively, professors of physics at the University of California in Santa Barbara, Caltech, and MIT. The discovery was made in 1973 by Gross and Wilczek at Princeton University and, independently, by Politzer at Harvard University. At the time, Wilczek was Gross's graduate student and Politzer was a graduate student of Sidney Coleman.

摘要:

The relentless demand for smaller, faster, cheaper, more capable computers continues to drive the development of devices for sensing and storing information. Over the past decade, manufacturers have exploited the phenomenon of giant magnetoresistance (GMR) to build sensors for reading data bits coded as tiny magnetized regions on disk drives. The higher sensitivity of these GMR read heads to magnetic fields has allowed a reduction in the bit size and hence an enormous increase in the storage capacity of magnetic hard disk drives.

摘要:

If a virus succeeds in planting its genome in a cell, the cell is doomed. Forced to follow the genome's orders, the cell makes the enzymes needed to replicate the genome and the proteins that constitute the viral coat. From coat proteins and replicated genomes, new, identical copies of the virus spontaneously assemble. The cell bursts, the viruses escape.
