... Science Frontiers ONLINE No. 40: Jul-Aug 1985 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects The Most Profound Discovery Of Science This is what one scientist calls Bell's Theorem. Certainly not all scientists would agree with such an absolute declaration. Since Bell's Theorem lurks in the fog-shrouded country of quantum mechanics, most biologists probably haven't even heard of it. In any event, they would probably think the discovery of the genetic code more profound. Why all the fuss over Bell's Theo-rem? In the laboratory, Bell's Theorem is associated with an admittedly spooky effect: the measurements made on one particle affect the measurements made on a second, far-removed particle. In theory, the second particle could be on the other side of the galaxy, with absolutely no physical connection between the two -- unless you admit to spooky action-at-a -distance forces. (Some over-ly zealous think-tankers have even contemplated applying this effect to long distance, untappable, unjammable communications with submarines!) The article (referenced below) in which this apparent magic is discussed also dwells on another profundity associated with quantum mechanics: does that which is not observed exist? Einstein felt intuitively that it did; and one of his remarks on the subject led to this article's title. Unfortunately for Einstein, all recent laboratory experiments demonstrate that spooky actionat-a -distance forces do exist and that Einstein's intuition was incorrect. (Mermin ...

... Subjects Dreams that do what they're told A few people can dream and, in their dreams, know that they are dreaming, and then take charge of their dreams, directing them to unfold according to their wishes. This all sounds occultish, to say nothing about far-fetched. It is called "lucid dreaming." F. van Eeden, a Dutch psychiatrist, defined lucid dreaming in this way: ". .. the reintegration of the psychic functions is so complete that the sleeper reaches a state of perfect awareness and is able to direct his/ her attention, and to attempt different acts of free volition. Yet the sleep, as I am able confidently to state, is undisturbed, deep and refreshing." Lucid dreams are real dreams. They occur during REM (Rapid Eye Movements) sleep, usually in the early morn ing, and they last 2-5 minutes. High levels of physical and emotional activity during the preceding day can encourage lucid dreaming. When lucid dreaming occurs, there are pauses in breathing, brief changes in heart rate, and changes in the skin's electric potential. There is even a recipe for triggering lucid dreaming. If you awake from a normal dream in the early morning, wake up fully but don't forget the dream. Read a bit or walk about, then lie down to sleep again. Imagine yourself asleep and dreaming, rehearsing the dream from which you awoke, and remind yourself: "Next time I'm dreaming, I want to remember I'm dreaming." Lucid ...
