MOORE There's still room for creativity. Designers are still going to have to think, Well, how do I use my billion-transistor limit? I don't anticipate the end of innovation...
...bell for Moore's law for decades. As physicist Carver Mead puts it, "The Chicken Little sky-is-falling articles are a recurring theme." But even Mead admits that by 2014 the laws of physics may have their final revenge. Transistor components are fast approaching the dreaded point-one limit--when the width of transistor components reaches .1 microns and their insulating layers are only a few atoms thick. Last year Intel engineer Paul Packan publicly sounded the alarm in Science magazine, warning that Moore's law could collapse. He wrote, "There are currently no known solutions to these problems...
...requisite processing power, which I estimate at about 20 million billion calculations per sec. (we have on the order of 100 billion neurons, each with some 1,000 connections to other neurons, with each connection capable of performing about 200 calculations per sec.). As Moore's law reaches its limit and computing power no longer doubles roughly every 12 to 18 months (by my reckoning, around 2019), conventional silicon chips may not be able to deliver that kind of performance. But each time one computing technology has reached its limit, a new approach has stepped in to continue exponential growth...
...size chunks any time soon. "Although the dam wall is showing signs of breaking now and there are huge economic benefits for both sides in working together, both Pyongyang and Seoul have an interest in taking things very slowly," says TIME U.N. correspondent William Dowell. "North Korea wants to limit the impact of outside contact on its closed ideological system, while South Korea is getting over an economic slump and would fear being overburdened by any sudden move to reunification. They're more likely to take incremental steps, over many years, rather than rush into a Germany-type scenario." Post...
...Italy,each claimed to have found a way to make light travel faster than its regular cruising speed of 186,000 m.p.s. According to the special theory of relativity, that's verboten; the velocity of light is supposed to be the cosmic speed limit, which nothing can exceed. Nevertheless, a physicist, Lijun Wang of the NEC Research Institute in Princeton, N.J., says he revved up a beam of light as much as 300 times its normal speed, using a special chamber filled with cesium gas. Now let's see him prove...
