Already, in fact, theoretical physicists have succeeded in constructing a framework that offers the best hope yet of integrating gravity with nature's other fundamental forces. This framework is popularly known as string theory because it postulates that the smallest, indivisible components of the universe are not point-like particles but infinitesimal loops that resemble tiny vibrating strings. "String theory," pioneering theorist Edward Witten of Einstein's own Institute for Advanced Study has observed, "is a piece of 21st century physics that fell by chance into the 20th century...
Which shapes represent the fundamental structures in our universe? On this point, string theorists are currently clueless. For the world conjured into existence by M theory is so exotic that scientists are being forced to work not just at the frontier of physics but at the frontier of mathematics as well. Indeed, it may be that they lack some absolutely essential tool and will have to develop it, just as Isaac Newton was pushed by his investigations of the laws of motion to develop the calculus. As if that weren't hard enough, there is yet another major impediment...
...relativism--that is, the idea that moral and ethical truth exists in the point of view of the beholder--owed nothing to Einstein (who believed the opposite), except a generalized homage to revolutionary thought. Art's elimination of semblances to the physical world corresponded vaguely with Einstein's way of seeing time and space, but it really sprung from an atmosphere of change, in which Einstein was yoked with Freud, Marx, Picasso, Bergson, Wittgenstein, Joyce, Kafka, Duchamp, Kandinsky and anyone else with original and disruptive ideas and an aggressive sense of the new. By that tenuous connection did the discoverer...
...little handwheel, sometimes 400 yards at a sitting. "I am spinning the destiny of India," he would say. The thread went to make cloth for his followers, and he hoped his example would convince Indians that homespun could free them from dependence on foreign products. But the real point of the spinning was to teach appreciation for manual labor, restore self-respect lost to colonial subjugation and cultivate inner strength...
Assassination made a martyr of the apostle of nonviolence. The Hindu fanatic who fired three bullets into Gandhi at point-blank range on Jan. 30, 1948, blamed him for letting Muslims steal part of the Hindu nation, for not hating Muslims. Not long before, Gandhi had noted his new irrelevance. "Everybody is eager to garland my photos," he said. "But nobody wants to follow my advice...
