...easy to understand why even Hawking was awed: he was looking at just a portion of the largest scientific instrument ever built. Known as the large electron-positron collider, this new particle accelerator is the centerpiece of CERN, the European Organization for Nuclear Research and one of Europe's proudest achievements. LEP is a mammoth particle racetrack residing in a ring- shaped tunnel 27 km (16.8 miles) in circumference and an average of 110 meters (360 ft.) underground. The machine contains 330,000 cubic meters (431,640 cu. yds.) of concrete and holds some 60,000 tons of hardware, including...

...deeper than a desire for federal dollars. To many scientists and politicians, national pride is at stake. Proponents insist that the SSC is necessary to keep the U.S. in the forefront of particle-physics research. Americans dominated the field from the mid-1940s to the 1970s, but Europe's CERN started stealing much of the glory in the 1980s. Without the SSC, its proponents contend, many of the best American physicists will emigrate to Europe. In fact, the brain drain has already begun: last year, for the first time, the number of American experimenters working at CERN surpassed the total...
