...photon puzzle was nothing more than a matter of speculation until 1964, when an Irish theoretical physicist named John Stewart Bell restated the problem as a simple mathematical proposition. A young physicist named John Clauser came upon Bell's theorem and realized that it opened the door to testing the two-photon problem in an experiment. Like Einstein, Clauser was bothered by the seemingly absurd implications of quantum mechanics. Says Clauser, now a research physicist at the University of California, Berkeley: "I had an opportunity to devise a test and see whether nature would choose quantum mechanics or reality...

...Keck telescope, as it will be called, is the first of a new generation of extra-large telescopes designed to overcome construction problems that have dogged sky gazers since before the Hale was dedicated in 1948. Photons (massless particles that transmit light) from an ancient galaxy may travel billions of light years through space before they speed down a telescope tube. But unless enough of them are collected, astronomers will not be able to see the galaxy's image. Gathering sufficient photons to register an image is accomplished by either taking long-exposure photographs or using a larger mirror system...
Physicists have long known that the photon, or light particle, was the carrier of electromagnetism. In 1979 in Hamburg, West Germany, they discovered the gluon, which conveys the strong force. This year CERN scored its crowning achievement by confirming the existence of three particles, the W+, W-and Z°, known collectively as intermediate vector bosons. They were predicted to be the agency of the weak force. That feat was a coup for a resurgent European physics community struggling to get back on its feet after World War II. It also irritated American scientists, who had regarded themselves...
