Political analysts point out the latter attribute has actually decreased in importance during this year's presidential campaign. Candidates have made a concerted effort to appeal to the anti-intellectual preferences of certain voters. John McCain, a Republican presidential candidate, frequently jokes about his fifth-from-the-bottom finish at the U.S. Naval Academy. Gore and Bradley have similarly made the effort to downplay their respective Harvard and Princeton educations in recent months...
Still don't know if you want to play? Take the simple quiz below and judge for yourself. If you get stuck, feel free to call a friend or use the fifty-fifty option at the bottom of this column. But be warned, there are no lifelines. If you fall, you fall all the way to ground negative-costs-minus-revenue...
That, says Lifset, is where nanotechnology plays a role. In this emerging field, which employs just about every kind of scientific and engineering discipline, researchers expect to create products by building them from scratch, atom by atom, molecule by molecule. This bottom-up nanotechnological way of making things differs from the traditional drilling, sawing, etching, milling and other fabrication methods that create so much waste along...
Consider too the sharks: apex predators, lords of the food chain, inspiration for scary stories. A few years ago, I dived off the coast of Costa Rica in a marine preserve where, supposedly, all life was protected. Every day, looking down, I saw the sea bottom carpeted with the corpses of whitetip reef sharks, grotesquely stripped of their fins by poachers who had slashed them off to sell to the soup markets of Asia and had cast the living animals back into the sea to die. Around the world, the numbers of some shark species have declined as much...
...argument hinges on the Gulf Stream, the ocean current that brings warm surface water north and east and heats Europe. As it travels, some of the water evaporates; what's left is saltier and thus denser. Eventually the dense surface water sinks to the sea bottom, where it flows back southward. And then, near the equator, warm, fresh water from tropical rivers and rain dilutes the salt once again, allowing the water to rise to the surface, warm up and begin flowing north again...
