  • Spectral lines: What's wrong with this picture?

    When we were kids, the puzzle page of the Sunday papers had a drawing containing, say, 20 erroneous or impossible items. In a reasonable length of time most of us could find all 20, and maybe even one or two more that the artist hadn't intended. Those puzzles came vividly to mind the other day when the newspapers ran a drawing of the support technique for the collapsed bridge in Mianus, Conn. Wouldn't any intelligent 12-year-old experienced enough to take his bicycle apart and reassemble it have found ¿what's wrong with this picture¿ in a matter of seconds? Large sections of the bridge (100 by 40 feet) were ¿hung¿ by four shear pins, one at each corner of the section. Several investigating teams were assigned to determine the cause of the bridge failure. Meanwhile, some of us who used to work those Sunday puzzles are ready to blame poor design. And we won't even invoke an equation to prove our case. We just looked at the mechanical drawing and said it was naive design. Though the official jury is still out, there are hints that we may be right. For example, bridge engineers are now saying that the design is ¿obsolete.¿ Yet the bridge is only 25 years old. (There are 60 more like it still in use in Connecticut alone.) Did the designers of this bridge ever hear of redundancy? The designers may have optimized ease of construction at the expense of reliability. View full abstract»

  • Govermnent: Keyworth at mid-term: An exclusive report from Presidential Science Advisor George A. Keyworth II on technology policy in the Reagan administration

    When George A. Keyworth II was appointed science advisor to the President two years ago. scientists and engineers in the United States, while not knowing much about Dr. Keyworth, were gratified that the post of science advisor would not be left empty in the new administration. That initial gratification may have since been forgotten. What some scientists and engineers are beginning to realize is that Dr. Keyworth is not so much their spokesman to President Reagan as the President's spokesman to them. For Dr. Keyworth, there never was any question about his mission from the day he took the job. View full abstract»

  • EE heroes and happenings: A philatelic review: The impending issuance of four new stamps prompts a retrospective look at electrotechnology from the philatelist's viewpoint

    Innumerable engineers and scientists have combined their professional interests and a fascinating hobby into a unified educational pastime. They collect stamps that are related to science and technology. Some of us have narrowed that collecting interest into a more specific area, such as telecommunications or power engineering. Others have broadened it to include mathematics, biology, medicine, and the like. View full abstract»

  • Researoh and development: Technology and the military: DOD's Darpa at 25: The Defense Advanced Research Projects Agency's funding of high-risk technology has led to both `Star Wars¿ weapons and computer breakthroughs

    When, last March 22, President Reagan called for a stepped-up effort to develop advanced weapons to defend against nuclear missiles, he was talking about programs the Defense Advanced Research Projects Agency (Darpa) was pursuing. Two weeks later, when the Department of Defense disclosed a new attempt to build an advanced supercomputer to match a government-backed program in Japan, the spotlight was again on Darpa. Darpa, which is marking its 25th anniversary this year, funds the initial research on high-risk projects that other civilian, Government, and private research organizations tend to shun.
