...take stock for a moment. To name just a few random things we did in a hundred years: we split the atom, invented jazz and rock, launched airplanes and landed on the moon, concocted a general theory of relativity, devised the transistor and figured out how to etch millions of them on tiny microchips, discovered penicillin and the structure of DNA, fought down fascism and communism, bombed Guernica and painted the bombing of Guernica, developed cinema and television, built highways and wired the world. Not to mention the peripherals these produced, such as sitcoms and cable channels, "800" numbers...
...result is one of the great statistical zingers of our age: every month, 4 quadrillion transistors are produced, more than half a million for every human on the planet. Intel's space-suited workers etch more than 7 million, in lines one four-hundredth the thickness of a human hair, on each of its thumbnail-size Pentium II chips, which sell for about $500 and can make 588 million calculations a second...
...could spark an unprecedented millennial boom, global in scope but empowering to each individual, marked not only by economic growth but also by a spread of knowledge and freedom and true community. That's a daunting task. But it shouldn't be much harder than figuring out how to etch more than 7 million transistors on a sliver of silicon...
...urged Americans to create a Russian buffet for 24 guests featuring coulibiac of bass; to make egg topiaries; to etch their own glass; and to garnish their Easter hams with grass so fresh from the yard that the morning dew had yet to disappear. She upstaged First Lady Hillary Clinton in wreath making, and the First Lady of Cooking, Julia Child, in pastry making. And she has admitted, without reservation, her determination to take over Christmas. So revitalizing K Mart, the $32 billion discount-store dud, should be a piece of cake for Martha Stewart...
...second problem was more subtle: a wire that is .25 microns wide is so small that once you've built it, you can't touch it. So instead of trying to unroll tiny wires onto silicon chips, microprocessor engineers laid down a thin sheet of metal and etched away everything they didn't want. What was left were microscopic paths of metal just wide enough to carry a current. But while chipmakers had developed any number of ways to etch aluminum, no one had yet figured out how to etch copper. Doing that, IBM suspected, would require inventing a whole...
