Special Lecture 29 December, morning and afternoon. Speaker: Herman Kahn (Director, Hudson Institute). Speculations on the Next Thirty-three Years. Among the important respects in which industrial so- ciety differs from all the societies that went before are the unprecedented degree of affluence, the extraordinary development of technology, and the institutionalization of secular, manipulative rationality, and thus of further eco- nomic and technological development. These basic trends of Western society can be seen as part of a common, complex trend of interacting elements—most of which can be traced back as far as the 12th or 11th centuries. For analytic purposes, we have separated them into 13 rubrics. These processes of change, each facilitating the other, have become routinely—one might even say inexorably— cumulative. It is notorious that as a result the rate of change of many aspects of economic and social life has become exponential; and it is not likely that many of the changes that are in process will begin to decelerate during the next third of a century. Some of these trends present serious issues; indeed some of the problems created by our successes in achieving unprecedented kinds of economic and technological powers may even be overwhelming. An attempt will be made to present a general framework designed to facilitate speculation and discussion about both the opportunities and the dangers that seem likely to arise in the next 33 years. Panel Discussion. Philip M. Hauser, Chairman Daniel Bell (Professor of Sociology, Columbia). Harrison Brown (Professor of Geochemistry, California Institute of Technology). Walter Sullivan (Science Editor, The New York Times). Hans H. Landsberg (Resources for the Future, Inc., Washington, D.C.). Scientific Research Society of America (RESA) Annual Address and Procter Prize 29 December, afternoon. Speaker: Abel Wolman (Professor of Sanitary Engineering Emeritus, Johns Hopkins University) Environmental Pollution. In the last five years Federal, State and regional legis- lation have vied with abatement in a push toward upgrading the quality of the air. In the haste toward action, it is not surprising that objective evaluation of the impact of all measures has fallen well behind desires and hopes. It is now timely and desirable to take a look at biologic, eco- nomic, scientific, technologic, and administrative consequences of the activities stressed by legislative action and public opinion. Such an orderly appraisal is obviously difficult, but at least a preliminary approach to an assessment seems about due. Chauncey Starr, Philip H. Abelson, E. J. Cassell, John R. Goldsmith, and B. Weinstock. General Lecture 29 December, afternoon. Speaker: B. F. Skinner (Harvard University). Teaching Science in High School—What Is Wrong? 1344 Fewer and fewer students go to college planning to become scientists and of those who go, more change t6 other fields. Perhaps science has become harder to teach. The status and role of the scientist may have changed. But another possibility is that those concerned with the improvement of teaching have not made sufficient use of recent advances in educational technology. Classroom experience is still accepted as a major source of wisdom. Consequences will be analyzed. The teacher who tries to make his subject interesting to the beginning student, for example, may not prepare him for the kind of thing which interests the informed scientist. The teacher who encourages the student to discover science for himself may neglect to transmit what is already known. The scientific analysis of learning and teaching has been neglected in spite of the fact that scientists above all others should turn to it for help. Sigma Xi-Phi Beta Kappa Lecture 29 December, evening. Speaker: John A, Wheeler (Princeton University). Our Universe: The Known and the Unknown. The formation of new stars and the explosion of old stars and the greatest variety of events, gigantic in scale and in energy, make the universe incomparably more interesting than any fireworks display that anyone could imagine in his wildest dreams. However, in all this wealth of events not one single effect has been discovered which has led to a new law of physics, and not one single finding has ever been obtained which is generally recognized to be incompatible with existing law. On the contrary, Einstein’s relativity and the quantum principle and the lesser laws together predict astonishing events—some of them like the expansion of the universe already observed and others on “the most-wanted list” of many present-day investigators. Among these are the “missing matter” predicted to be present by Einstein’s theory and the “black holes” predicted to result from the “continued gravitational collapse” of an over-compact mass. No prediction of standard well-established theory is more revolutionary than “superspace,” the dynamical arena of Einstein’s general relativity, and none seems more likely to have consequences for all of physics, from elementary particle physics to the dynamics of the universe. IHustrated Lecture of the National Geographic Society 30 December, evening. Speaker: Bradford Washburn (Boston Museum of Science). Mapping Mount Kennedy. The motion picture Mapping Mount Kennedy covers the story of Dr. Washburn’s expedition to map the St. Elias range of Canada’s Yukon Territory in 1965. This expedition was sponsored by the National Geographic Society and Boston’s Museum of Science, and its success was made possible by the cooperation and assistance provided by the government of Canada. Dr. Washburn also led the Society’s 1935 expedition which discovered the peak named by Canada in honor of the late president John F. Kennedy in 1964. The film includes a section on this 1935 expedition as well as covering the first ascent of Mount Kennedy made in March 1965. SCIENCE, VOL. 158
