Slightly Frustrated. Unlucky Number? Prof. Peter A.

He is just a Ga'e Descrbes Thinking As Psychological Process put emphasis on a carefully or- ganized structure to make sure that students have the basic ideas with which to work, he said. Prof. Gagne listed four basic research conclusions on thinking: 1) People tend to get into ruts in their thinking;; 2) Thinking is greatly influenc-' ed by what is said to the thinker; 3) Errors in thinking are not usually errors in logic. In most- cases the cause is distraction; and 4) "Successful" thinking is def-. initely related to the number of. ideas one has. "We need to know more about thinking conditions, such as nev- vous system growth, learning pre- conditioning and the immediate communication -needed for think- ing," Prof. Gagne said. Five Stages He divided problem solving- directed thinking-into the stages- of problem definition, concept for- mation, determination of courses of action, decision-making and verification of that decision. Successful problem solving is not a matter of practicing a single form of behavior, such as inven- tiveness. or creativity. Also, stu- dents cannot be made to solve problems successfully by exhorting them to be creative or inventive, -Prof. Gagne concluded. His talk was part of a series on teaching and learning in the field of medicine. The series is sponsored by the Center for Re- search on Learning and Teaching. little frustrated because he and his colleagues have been trying since before the MIT experiment to shoot a laser off the moon with the University's 36-inch telescope. Typical Ann Arbor weather pre- vented such a "first" from being accomplished. Some MIT officials were irked that they had not been told about the "stunt" beforehand -it was a well kept secret among those working on the experiment. } "Of course,.it was just a stunt," Prof. Franken says. "But it catch- es the public eye and gets in some national magazine. It could do more. for getting money for re- search, for instance, from a legis- lature, than some speeches." Not Much Chance Right now, Prof. Franken doesn't see much of a chance of ever getting a moon bounce done here. He is at Yale University now, on a sabbatical from his work at the University, but if the equip- -meat is set up and the weather is good this spring, he will return to the campus immediately to see if his group can do what they have trot been able to do for almost a year. "We had six men working hard to set the thing up last spring, but the weather was always too bad to conduct the experiment. Al- so, our telescope scatters too much light. It's a fine telescope, but it's 50 years old," he says. Bouncing a laser beam off the moon is like shooting a stream of water at a target a quarter of a million miles hway and hoping to catch some of the drops as they spray back. Drop Diversity With the sensitive instruments existing today, those precious "drops" can be caught, but they have to be distinguished from other "drops" that may not be a part of the experiment but still occlude the results. Many conditions must be met to catch the "drops" of light. The moon must be in the right posi- tion, a little less than half-illum- inated, and the weather must be clear all the way through tne at- mosphere-not just near the sur- face of the earth.' The mirror of the telescope. is the light gathering surface that must be of a good enough quality to capture the few photons that return from the moon, and an ex- tremely sensitive photocell elec- tronically counts these photons. Single Frequency The heart of the entire opera-f tion, the laser, sends out its light at a single, sharp frequency The most commonly used laser is made of a ruby crystal. The wave length of the' i lit eitted is singular for, .the. ruby crystal-6,934 Ang- stroms. This is at.die far end of the vis- ible light spectrum, near the infra- red. As the light passes through the .atmosphere, it loses 10 per cent of its power in both directions. The light spreads about five in- ches for every mile it travels, reaching the. moon with a beam radius of only 20 miles. For any type of light, this is a very small spread for such a great distance. MIT scientists aimed their laser to get maximum reflection from the moon. A new moon or a moon reflecting no sunlight back to the earth cannot be used because it is high enough in the sky only at times when the sunlight would in- terfere with the experiment. Between Phases So a compromise is taken be- tween the moon's new and full phases. When the light returns to the earth, filters remove all wave lengths around 6,934 Angstroms that would interfere with the pho- tocell as it counts the returning ph o t ons. Otherwise, ordinary moonlight and light in the earth's atmosphere would obscure the photocell's operation. MIT scientists "shot" the 13 separate spurts of light a minute] apart to allow the laser to cool off between "shots." They said that they detected the returning pho- tons-about 12 each time. Members of the group that have been working on the University's moon bounce experiment with Prof. Franken are Prof. Dean B. McLaughlin of the astronomy de- partment, Prof. Murray Miller of the electrical engineering depart- ment, Wes Vivian and Lee Evans of a local engineering firm that has supported the project, and Lloyd Cross, Bill Fredricks and Hank Laughlin of another local firm that has supported the work.!

'Say Goodbye to your R o ommante" WILLIAM JOY .. defense report Prof. Joy explained the "thou- sands of details" to be taken care of in any catastrophe that would hinder the effective working of any program. The University, with one-sixth the total resources of the city of Detroit and more than twice those of the rest of Washtenaw Couty, has taken only a "tentative ap- proach to the problem" with no strategic or policy assumptions, Ostafin said. It does not believe in civil defense exercises, or site- ilar preparations and is relying on students "to behave in a mature and ingenious manner" he added. Solari pointed out that any civil defense program has the tendency to make people feel safer and as a result more antagonistic to the problem of international relations. However, they explained the report as devoid of any moral or ethical justification and merely as an an.- alysis of the problem facing the :University. The report points out that the steam tunnel system, previously believed to be an ideal means of communication and transportation between shelter areas, has inade- quate ventilation and is poorly identified. In addition, any rup- ture of steam pipes in any tunnel area would immediately make the areas unlivable. The question of whether or not the University should join the pro- gram of the federal government, whereby some monetary assistance is exchanged for making its shel- ters open to the public at large, has been sent to the administra- tion w i t h o u t recommendation either way. .II 11 EASTMAN COLO ?'
