...music-video sales. That the image refracted in the media-crazed mirror never settles is hypnotizing. Her throwaway line "Experience has made me rich/ And now they're after me," from her tune Material Girl, seems more a wily prophecy than mere egoistic cant. Her latest public catharsis -- a quantum artistic growth spurt, if you will -- is Truth or Dare. It is a panoramic, emetic, beauty-marks-and-all, feature-length autobiographical documentary shot during her Blond Ambition tour. The film, which opens nationally on May 17, is a celebrity voyeur's feast that draws its substance from the dark...
...Silverstein '92 does research in quantum mechanical systems with Arthur M. Jaffe, professor of mathematics and theoretical science. Jaffe say he was pleasantly surprised how much he learned from working with Silverstein...
...consequence could be to establish the boundaries of quantum mechanics, which says particles can suddenly jump from one place to another without traversing the space in between. Penrose's intuition, although he has no proof, is that these effects may apply not just to atoms but also to objects as big as brain cells. An act of creative thinking, he argues, could be the outward manifestation of neurons making quantum jumps from one energy state to another. Since computers do not operate by quantum rules, he says, they will never have insights...
Moreover, he believes, quantum gravity could be behind consciousness itself. The argument is tricky, but one reason for this belief is that consciousness carries with it a peculiarity that baffles physics: humans perceive time as moving forward rather than backward. But virtually all the laws of physics are time symmetric -- they work equally well in forward or in reverse -- and the mind presumably operates by physical laws...
Penrose's answer is that when quantum gravity is finally constructed, it will prove to be time asymmetric -- that is, it will not work in reverse. Why? Because the Big Bang that started the universe must, at its earliest moments, have been governed by quantum gravity. And the Big Bang was surely a time- asymmetric phenomenon that could not happen in reverse. If quantum gravity winds up being the theory governing the mind, that will also explain why time moves forward, not backward...
