单选题For the first time, George Bush has acknowledged the existence of secret CIA prisons around the world, where key terrorist suspects—100 in all, officials say—have been interrogated with "an alternative set of procedures". Fourteen of the suspects, including the alleged mastermind of the September 11th attacks, were transferred on Monday to the American naval base at Guantánamo Bay in Cuba, where some will face trial for war crimes before special military commissions. Many of these men—as Mr. Bush confirmed in a televised speech at the White House on September 6th—are al-Qaeda operatives or Taliban fighters who had sought to withhold information that could "save American lives". "In these cases, it has been necessary to move these individuals to an environment where they can be held secretly (and) questioned by experts," the president said. He declined to say where they had been held or why they had not simply been sent straight to Guantánamo, as some 770 other suspected terrorists have been. Mr. Bush also refused to reveal what interrogation methods had been used, saying only that, though "tough", they had been "safe and lawful and necessary". Many believe that the main purpose of the CIA's prisons was to hide from prying eyes the torture and other cruel or degrading treatment used to extract information from prisoners. But Mr. Bush insisted that America did not torture : "It's against our laws, and it's against our values. I have not authorised it—and I will not authorise it." The Pentagon this week issued its long-awaited new Army Field Manual, forbidding all forms of torture and degrading treatment of prisoners by army personnel—though not the CIA. For the first time, it specifically bans forced nakedness, hooding, the use of dogs, sexual humiliation and "waterboarding" (simulated drowning )—all practices that have been used at Guantámamo and Abu Ghraib. So why did the president decide now to reveal the CIA's secret programme? Partly, he confessed, because of the Supreme Court's recent ruling that minimum protections under the Geneva Conventions applied to all military prisoners, no matter where they were. This has put American agents at risk of prosecution for war crimes. Mr. Bush has now asked Congress to ban suspected terrorists from suing American personnel in federal courts.

单选题 Will there ever be another Einstein? This is the undercurrent of conversation at Einstein memorial meetings throughout the year. A new Einstein will emerge, scientists say. But it may take a long time. After all, more than 200 years separated Einstein from his nearest rival, Isaac Newton. Many physicists say the next Einstein hasn't been born yet, or is a baby now. That's because the quest for a unified theory that would account for all the forces of nature has pushed current mathematics to its limits. New math must be created before the problem can be solved. But researchers say there are many other factors working against another Einstein emerging anytime soon. For one thing, physics is a much different field today. In Einstein's day, there were only a few thousand physicists worldwide, and the theoreticians who could intellectually rival Einstein probably would fit into a streetcar with seats to spare. Education is different, too. One crucial aspect of Einstein's training that is overlooked is the years of philosophy he read as a teenager—Kant, Schopenhauer and Spinoza, among others. It taught him how to think independently and abstractly about space and time, and it wasn't long before he became a philosopher himself. 'The independence created by philosophical insight is—in my opinion—the mark of distinction between a mere artisan (工匠) or specialist and a real seeker after truth,' Einstein wrote in 1944. And he was an accomplished musician. The interplay between music and math is well known. Einstein would furiously play his violin as a way to think through a knotty physics problem. Today, universities have produced millions of physicists. There aren't many jobs in science for them, so they go to Wall Street and Silicon Valley to apply their analytical skills to more practical—and rewarding—efforts. 'Maybe there is an Einstein out there today,' said Columbia University physicist Brian Greene, 'but it would be a lot harder for him to be heard.' Especially considering what Einstein was proposing. 'The actual fabric of space and time curving? My God, what an idea!' Greene said at a recent gathering at the Aspen Institute. 'It takes a certain type of person who will bang his head against the wall because you believe you'll find the solution.' Perhaps the best examples are the five scientific papers Einstein wrote in his 'miracle year' of 1905. These 'thought experiments' were pages of calculations signed and submitted to the prestigious journal Annalen der Physik by a virtual unknown. There were no footnotes or citations. What might happen to such a submission today? 'We all get papers like those in the mail,' Greene said. 'We put them in the junk file.'
