Proceedings of the First Lunar International Laboratory (LIL) Symposium Research in Geosciences and Astronomy: Organized by the International Academy of Astronautics at the XVIth International Astronautical Congress Athens, 16 September, 1965 and Dedicated to the Twentieth Anniversary of UNESCO

by Frank J. Malina

The Lunar International Laboratory (LIL) project of the International Academy of Astronautics was begun upon the proposal of the editor at the First Special Meeting of the Academy at Stockholm on 16 August 1960. The late THEODORE VON KARMAN, first President of the Academy, appointed the following members of the LIL Committee: Prof. N. BoNEFF (Bulgaria), Prof. M. FLoRKIN (Belgium), Mr. A. G. HALEY (U. S. A. ), Prof. Sir BERNARD LovELL (U. K. ) (Vice­ Chairman), Prof. L. MALAVARD (France), Dr. F. J. MALINA (U. S. A. ) (Chairman), Prof. H. 0BERTH (German Federal Republic), Dr. W. H. PicKERING (U. S. A. ), Prof. E. SANGER (German Federal Republic), Prof. L. I. SEDOV (U. S. S. R. ), Prof. L. SPITZER, JR. (U. S. A. ), Dr. H. STRUGHOLD (U. S. A. ), Prof. H. C. UREY (U. S. A. ) and himself. Since 1960 the following additional members were appointed to the Committee: Mr. A. C. CLARKE (U. K. ), Prof. A. DoLLFUS (France), Prof. Z. KoPAL (U. K. ), Dr. S. F. SINGER (U. S. A. ), Prof. N. M. SISSAKIAN (U. S. S. R. ) and Prof. F. ZWICKY (Switzerland). The Academy authorized the Committee to study the technical problems related to the construction of a manned research laboratory on the Moon and the feasibility of carrying out its construction, and to consider the fields of research which would initially be undertaken.

Rheology and Soil Mechanics / Rhéologie et Mécanique des Sols: Symposium Grenoble, April 1–8, 1964 / Symposium Grenoble, 1Er–8 Avril 1964 (IUTAM Symposia)

by J. Kravtchenko P. M. Sirieys

For a long period Soil Mechanics has remained at the semi-empirica stage, and only a few decades ago it has shown a tendency to become a fundamental science. However, this evolution is taking place slowly; in spite of the efforts of numerous research scientists, the very complex rheological laws of soils are still not well known. Even if these laws were elucidated, it would take a long time still to deduce simple rules from them for reliable and convenient use in current practical engineer­ ing. In the pursuit of these distant aims - and of others more imme­ diate - fundamental research and applied research are very active, both in Rheology and Soil Mechanics. The complexity of the problems to be solved should incite the laboratory researchers and the engineers to a continuous collaboration. Everyone acknowledges the advantage of these connections although aware of the difficulty of realizing this wish. However, contacts are being made little by little between the repre­ sentatives of the different branches of Rheology and Soil Mechanics, to the great benefit of science. The bureau of the International Union of Theoretical and Applied Mechanics (IUTAM), aware of the importance of these two associat­ ed fields of mechanics, considered it possible to accelerate the natural and necessary processus of their interpenetration by organizing in Grenoble, from 1st to 8th April 1964 an International Symposium on Rheology and Soil Mechanics.

Trajectories of Artificial Celestial Bodies as Determined from Observations / Trajectoires des Corps Celestes Artificiels Déterminées D’après les Observations: Proceedings of a Symposium Held in Paris, April 20–23, 1965

by J. Kovalevsky

In May 1962 the International Union of Theoretical and Applied Mechanics (IUTAM) organized a symposium in Paris on the theory of the movement of the Earth's artificial satellites designated to confront the results of the first spatial experiences with the mechanical point of view. The papers submitted during this meeting have been published in 1963 in a collection entitled "Dynamics of Satellites" by Springer­ Verlag. During the last three years the importance of studies pertaining to the dynamics of artificial satellites has continued to increase, and many results due to observations have led to a deeper knowledge of the field of forces in which these objects move, particularly the field of gravitation of the Earth, the forces due to pressure of radiation, friction of the atmosphere, etc . . . A new symposium seemed therefore suitable to determine these recent advances. However, this time it appeared appropriate to consider it more from the point of view of the interpretation obtained from the results of observations (determination of orbits and forces existing) than from the point of view of the theory of motion. For this reason the complete title of the second symposium is as follows: "Trajectories of Artificial Celestial Bodies, as Determined from Observations".

Proceedings of the Second International Symposium on Basic Environmental Problems of Man in Space: Paris, 14–18 June 1965

To Save the Phenomena: An Essay on the Idea of Physical Theory from Plato to Galileo

by Pierre Duhem

Duhem's 1908 essay questions the relation between physical theory and metaphysics and, more specifically, between astronomy and physics–an issue still of importance today. He critiques the answers given by Greek thought, Arabic science, medieval Christian scholasticism, and, finally, the astronomers of the Renaissance.

Vth International Congress on X-Ray Optics and Microanalysis / V. Internationaler Kongreß für Röntgenoptik und Mikroanalyse / Ve Congrès International sur l’Optique des Rayons X et la Microanalyse: Tübingen, September 9th–14th, 1968

by Gottfried Möllenstedt K. H. Gaukler

The Fifth International Congress on X-Ray Optics and Microanalysis was organized by the Institute of Applied Physics at Tübingen University in Western Germany from September 9th through 14th, 1968. Since 1956, when the First Conference was arranged in Cambridge, England by one of the pioneers in this field, V. E. CossLETT, the experts in the fields of X-Ray Optics and Microanalysis have met every third year to exchange their scientific experiences. Later meetings were held at Uppsala, Sweden in 1959, at Stanford, California in 1962, and at Orsay, Francein 1965. The participants in the 1968 Conference came from the following countries: Germany 140, France 60, Great Britain 55, USA 20, Netherlands 16, Switzerland 12, Austria 9, Sweden 7, Belgium 6, Japan 5, Italy 4, two each from Israel, Yugoslavia, Canada, Norway, Hungary and one each from Argentine, Poland, South Africa. As at the latest congress in Paris the following central topics were treated: General problems of X-ray optics, physical bases of electron beam microanalysis, quantitative problems of X-ray microanalysis, instrumentation, microdiffraction, applications to metal­ lurgy, mineralogy, and biology. An exhibition showing some of the most modern instruments formed an important part of the conference. The Springer-Verlag, Heidelberg, deserves thanks for the careful and speedy work they have performed in printing these conference proceedings. We are further indebted to all contributors of this volume for their kind cooperation. Tübingen, August 1969 G. MöLLENSTEDT and K. H.
