...generally regarded as a sort of petrified object, rendered deaf and blind by the years," Albert Einstein confided near the end of his life. He was, alas, correct. During the last three decades of his remarkable career, Einstein had become obsessed by the dream of producing a unified field theory, a series of equations that would establish an underlying link between the seemingly unrelated forces of gravity and electromagnetism...
Einstein was brilliant, of course, but he was also lucky. When he developed the general theory of relativity, he dealt with a world that had just three spatial dimensions plus time. As a result, he could use off-the-shelf mathematics to develop and solve his equations. M theorists can't: their science resides in an 11-dimensional world that is filled with weird objects called branes. Strings, in this nomenclature, are one-dimensional branes; membranes are two-dimensional branes. But there are also higher-dimensional branes that no one, including Witten, quite knows how to deal with. For these...
Roosevelt purposely limited his fireside talks to an average of two or three a year, in contrast to the modern presidential practice of weekly radio addresses. Timed at dramatic moments, they commanded gigantic audiences, larger than any other program on the radio, including the biggest prizefights and the most popular comedy shows. The novelist Saul Bellow recalls walking down the street on a hot summer night in Chicago while Roosevelt was speaking. Through lit windows, families could be seen sitting at their kitchen table or gathered in the parlor listening to the radio. Under the elm trees, "drivers had pulled...
...This "Bringer of Light" led his people through decades of fighting against three major powers to secure independence for this country...
...next 33 years, he led three major crusades to undermine the power and moral defenses of the British Raj. In 1919-22 he mustered widespread nonviolent strikes, then a campaign of peaceful noncooperation, urging Indians to boycott anything British--schools, courts, goods, even the English language. He believed mass noncooperation would achieve independence within a year. Instead, it degenerated into bloody rioting, and British soldiers turned their guns on a crowd in Amritsar, massacring 400. Gandhi called his underestimating of the violence inside Indian society his "Himalayan blunder." Still, villagers mobbed him wherever he went, calling him Mahatma...
