...Revolutionary forces. The 17th century, on the other hand, despite such colorful leaders as Louis XIV and the ch?teau he left us, will be most remembered for its science: Galileo exploring gravity and the solar system, Descartes developing modern philosophy and Newton discovering the laws of motion and calculus. And the 16th will be remembered for the flourishing of the arts and culture: Michelangelo and Leonardo and Shakespeare creating masterpieces, Elizabeth I creating the Elizabethan...
...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 to progress: unlike quantum mechanics, string theory and its offshoots have developed in the virtual absence of experimental evidence that could help steer theorists in productive directions...
...time from 1665 to 1667. Newton lived to be 84. Before he was done, his comprehensive intelligence--with which he seemed to have thought and tinkered his way into the very mind of God--had set off not one but four scientific revolutions--in mathematics (he invented the calculus, as did Leibniz in Germany, independent of Newton), in optics (he invented the reflecting telescope, and his experiments with spectrums established the nature of color and the heterogeneous components of sunlight), in mechanics (his three laws of motion changed the world) and with his understanding of gravity. The last explained...
...overheard Adams telling the police that her "boyfriend" had shot her. "Her composure and ability to talk with us were amazing considering the way she was hurt," says police spokesman Keith Bridges. But could Carruth possibly have been capable of what some speculate was a crime of the coldest calculus--murder to avoid paying child support? Surely his weekly salary of $38,000 could cover that expense in addition to the $3,500 a month he was contributing to support a son in Sacramento, Calif...
Middle-class blacks who live in Webster Groves and have strong role models tend to score higher--but can still feel isolated. By third period, senior Paya Rhodes, 18, is in her advanced-calculus class, sitting beside the only other black student. Rhodes has a 3.6 GPA, and in most of her advanced classes, she's the only black. Paya used to take pride in that status and in her family's record of excellence at Webster Groves. Her oldest brother maintained a 4.0 for four straight years; another went on to Washington University. Her mother and a third brother...
