...their opportunity has come. This week the space shuttle Discovery was scheduled to take off and deliver into earth orbit the Hubble space telescope, a bus-size instrument that will see the cosmos ten times as clearly as any ground-based telescope ever has. Scientists have impatiently awaited the historic launch through three years of delays caused by the shuttle's problems in the aftermath of the Challenger explosion...
...remarkable demonstration of the precision with which single atoms can now be manipulated, a skill that could conceivably be used someday to build atom-size transistors or to custom-design molecules. Using an instrument called a scanning tunneling microscope and working on a surface chilled to near absolute zero, researchers Donald Eigler and Erhard Schweizer were able to get individual atoms to respond to the magnet-like tug of a fine tungsten needle. But don't expect to see atom-etching booths at your local science fair. It took 22 hours to haul 35 xenon atoms across the bumpy nickel...
...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...
...reforms succeed, Kemp will be remembered for turning a bureaucratic cesspool into an effective and vibrant instrument of reform...
...could the dread strike have become such an uncertain instrument? The right of union members to strike without losing their jobs has long been a cherished tenet of the American labor movement. The National Labor Relations Act of 1935 does indeed grant them that right. But while the statute prohibits employers from firing or punishing striking union members, those same employers can cite a 1938 Supreme Court decision giving them the right to hire permanent replacements for workers who are striking for such "economic reasons" as pay hikes or benefits (as opposed to unfair labor practices). In other words...
