Of all the reasons for exploring the Universe, none is more com pelling than the possibility of discovering intelligent life elsewhere in the Universe. Still the quest for extraterrestrial life has been near the bottom of the astronomers' list of priorities, not because the number of extraterrestrial civilizations is conjectured to be van ishingly small, but because our powers of detection were thought to be far too weak. About ten years ago, however, the growing reach of ra dio telescopes on the ground and of optical and infrared telescopes in space persuaded a number of thoughtful astronomers that the time for a more serious search had arrived. Accordingly, a joint Soviet-American conference on the problems of Communication with Extraterrestrial In telligence was convened at the Byurakan Astrophysical Observatory of the Armenian Academy of Sciences during September 5-11, 1971 and was soon followed by a number of other important meetings, notably a series of NASA-sponsored workshops in the USA held between January, 1975 and May, 1976. Since SETI is fundamentally an international undertaking and as tronomical methods and techniques are required for its pursuit, it is natural for the International Astronomical Union to lend its support by sponsoring conferences and otherwise facilitating cooperation among countries. The active involvement of the I. A. U.

Buch. Condizione: Neu. Neuware - The essays in this book deal with a number of problems in the analysis of intensional language - more especially with the analysis of the personal modalities in natural language. Together they cover a representative spectrum of the problems of contemporary ,interest in this area, in a way that should make them of interest to linguists, logicians and philosophers concerned with natural language. The contributors are mostly more linguists than logicians or philosophers but some are more logicians or philosophers than linguists. As far as possible, we have tried to conduct the discussion in terms that will enable students from any of these fields to come to grips with the central issues. This volume will provide, I think, material for a very stimulating course. I have used it as the basis for a course at the introductory level in the philosophy of language. The essays in the book led us back to look at the classic texts and a good deal of the intervening literature crept in of its own accord. Out of that experience grew the introduction that follows. In contrast with the rest of the book, the introduction is frankly pedagogical. I hope and believe that many who would otherwise find the papers themselves hard to digest will ~e helped on their way by that summary.

Taschenbuch. Condizione: Neu. Neuware - The impressive record of Italian philosophical research since the end of Fascism thirty-two years ago is shown in many fields: esthetics, social and' personal ethics, history and sociology of philosophy, and magnificently, perhaps above all, in logic, foundations of mathematics and the philosophY, methodology, and intellectual history ofthe empirical sciences. To our pleasure, Maria Luisa Dalla Chiara of the University of Florence gladly agreed to assemble a 'sampler' of recent Italian logical and analytical work on the philosophical foundations of mathematics and physics, along with a number of historical studies of epistemological and mathematical concepts. The twenty-five essays that form this volume will, we expect, encourage English-reading philosophers and scientists to seek further works by these authors and by their teachers, colleagues, and students; and, we hope, to look for those other Italian currents of thought in the philosophy of science for which points of departure are not wholly analytic, and which also deserve study and recognition in the world wide philosophical community. Of course, Italy has long been related to that world community in scien titlc matters.

This item is printed on demand - it takes 3-4 days longer - Neuware -The bib I iography includes papers in alI fields of photosynthesis research - from stu dies of model biochemical and biophysical systems of the photosynthesis mechanism to primary production studied by the so-cal led growth analysis. In addition to papers devoted entirely to photosynthesis, papers on other topics are included if they con tain data on photosynthetic activity, photorespiration, chloroplast structure, chlo rophyl I and carotenoid synthesis and destruction; etc. , or if they contain valuable methodo I og i ca I information (measurement of se I ected env i ronmenta I factors, I eat area, etc. ). In many branches it has been very difficult to define the I imits of interest for photosynthesis researchers. This problem has arisen e. g. in topics dealing with the transport of gases, where- in addition to the papers on C0 transfer- some pa 2 pers on water vapour transfer are included, these being of general application. On the other hand, many papers dealing with the anatomy and physiology of stomata have been omitted, if the aspect of carbon dioxide or water vapour exchange has not been discussed. This volume contains references to papers pub I ished in the year 1976, and, similarly to Vol. 6, also addenda including references pub I ished in the preceding period (i. e. 1966- 1975 ). The numbers of these additional references are label led with an asterisk in the I ist of references. 320 pp. Englisch.
