...concretely means is anyone’s guess.This column won’t claim to divine the future of radio. The myriad problems with radio are far too numerous to be remedied by one miracle cure-all. But there continues to be new ways that radio can retain its ostensible purpose—to be both reflections and creators of the public’s taste in music. Internet radio allows still-untapped possibilities to disseminate once hard-to-come-by musical events, as evidenced by the Metropolitan Opera’s decision to broadcast over Sirius Satellite Radio.High school...
...more powerful processors that generate incredible amounts of heat. (Just try working with your laptop computer actually on your lap for a few hours.) "When you go to the next-generation semiconductor, you're running something not too different from a toaster oven," Sadoway says. Because it doesn't retain heat, diamond can run processors of supercomputing power at lower temperatures compared with processors using silicon, the industry standard today. The molecular structure of diamond makes it ideal for handling high voltages like those found in switches for big municipal power grids. Physically, diamond's toughness allows it to withstand...
Also tracking the progress of diamondmaking are biologists, who covet the gem's inertness--it doesn't react with other substances--and its ability to retain its structural integrity despite being bathed in natural acids and other organic compounds. One possible application: diamond-based electrodes, implanted under the skin, that could be designed to react chemically in the presence of certain proteins. Already, researchers at Case Western Reserve University have developed such a prototype for detecting levels of a protein critical to nerve-cell activity...
...mechanism for cooperative study. The creation of HUSEC and the allocation of $50 million has been greeted with unsurprising enthusiasm from the Faculty. The only reservation has been about the interaction between HUSEC and departments: The Faculty wants HUSEC to remain an advisory committee and allow existing departments to retain their autonomy. This concern was first voiced when UPCSE released its preliminary report in July, and the final report “emphasizes that [HUSEC] should not be directive at lower levels of academic structure,” according to Biewener. He explained that, although it has autonomy over...
...that is an illusion. The mirror is really a pool of liquid mercury in a shallow wood container. A touch would send ripples racing across its surface, and it must always aim straight up to retain its curvature. As the container is slowly rotated on a turntable; making one revolution every six seconds, the mercury rises gently toward the edges and dips in the middle, the way coffee does when it is stirred in a cup. In perfect deference to the laws of physics, the metal's highly reflective surface takes the form of a parabola, the shape of solid...
