Two articles by Lewis Feuer caught my attention in the '40s when 1 was wondering, asa student physicist, about the relations of physics to philosophy and to the world in turmoil. One was his essay on 'The Development of Logical Empiricism' (1941), and the other his critical review of Philipp Frank's biography of Einstein, 'Philosophy and the Theory of Relativity' (1947). How extraordinary it was to find so intelligent, independent, critical, a...

The most incomprehensible thing about the world is that it is comprehensible.' ALBERT EINSTEIN, 1950 The tremendous progress of recent years in the field of isotopes in the earth sciences has proved invaluable in attempting to solve a varied spectrum of geological and geochemical problems. The lunar exploration programmes provided rocks for analysis, stimulating refinements in mass spectrometry which were later used for terrestrial samples too...

This book is written to help human service program administrators either in­ terpret or conduct program evaluations. Our intended audience includes admin­ istrators and those students being trained for careers in human services administration. Our focus is on persons interested in assessing programs in which people work with people to improve their condition. The book's title, Program Evaluation: A Field Guide for Administrators, describes how...

Most forest tree species were considered recalcitrant a decade ago, but now with the improved in vitro techniques some progress has been made towards culture-of tree species. Micro­ propagation has been achieved from the juvenile tissues of a number of forest tree species. On the other hand, tissues from most mature trees are still very difficult to grow and differen­ tiate in vitro. Nevertheless, there has been slow but steady progress in the...

This book is a welcome reassertion of an old tradition of interdisdplinary research. That tradition has tended to atrophy in the last decade, largely because of an enormous expansion of the domain of neoc1assical economics. The expansion has fed on two sdentific developments: first, human capital theory, second, contract theory. Both developments have taken phenomena critical to the operation of the economy but previously understood in terms o...

For a long time I would not eat strawberries. In 1977, a scandal broke about a testing laboratory having falsified the data that was used to register a large number of pesticides. The Canadian government, along with several others, began the process of re-evaluating both the procedures for testing and these specific chemicals. One chemical proved particularly controversial, the commonly-used pesticide named captan. In light of the controversy,...

Il capitano generale lagrimo per allegrezza e nomino quel capo: Deseado, perehe l'avevamo gia gran tempo desiderato. Antonio Pigafetta Il Primo Viaggo in torno al Mondo I would like to take some poetic license in introducing this volume in a way that seems appropriate for a country, like Chile, that Iooks to the ocean. I believe it was Heisenberg who compared different times in physics with sailing a ship. He said that most of the time we keep...

This volume contains the Proceedings of the International Colloqui­ um "Newton's Scientific and Philosophical Legacy", that was held at the Catholic University of Nijmegen (The Netherlands) from June 9th to 12th 1987 to celebrate the Tercentenary of the publication of Newton's Philo­ sophiae Naturalis Principia Mathematica (1667). Although 1987 was a busy year for Newton scholars, we were happy that five of most prom­ inent among them were abl...

This volume contains a number of studies on Jewish-Christian re­ lations, in which special attention is given to the Netherlands and England, and the texts of some recently discovered and other rare documents in the same field. The work originates in a symposium on this subject held on 23 January 1985 at the University of Leiden under the auspices of the Sir Thomas Browne Institute for the study of Anglo-Dutch relations. Various authors have c...

In a review written in 1979, I noted that there was a paucity of research examining the effects of maternal employment on the infant and young child and also that longitudinal studies of the effects of maternal em­ ployment were needed (Hoffman, 1979). In the last 10 years, there has been a flurry of research activity focused on the mother's employment during the child's early years, and much of this work has been longi­ tudinal. All of the st...

Two-phase flow heat exchangers are vital components of systems for power generation, chemical processing, and thermal environment control. The art and science of the design of such heat exchangers have advanced considerably in recent years. This is due to better understanding of the fundamentals of two-phase flow and heat transfer in simple geometries, greater appreciation of these processes in complex goemetries, and enhanced predictive capab...

Proceedings of the NATO Advanced Research Workshop on Mechanical Vibrations and Audible Noise in Alternating Current Machines, Leuven, Belgium, August 4-8, 1986

Since publication of the first edition of this Handbook, the usage of thenno­ plastic elastomers (TPEs) has doubled, with a compounded annual growth rate of approximately 9 percent. This second edition summarizes and documents the technological and commercial progress that has given rise to this phenomenal rate of growth. Over the past decade, numerous suppliers and users of ther­ moplastic elastomers have entered the field, and some have reti...

Insects multiply. Destruction reigns. There is dismay, followed by outcry, and demands to Authority. Authority remembers its experts or appoints some: they ought to know. The experts advise a Cure. The Cure can be almost anything: holy water from Mecca, a Government Commis­ sion, a culture of bacteria, poison, prayers denunciatory or tactful, a new god, a trap, a Pied Piper. The Cures have only one thing in common: with a little patience they ...

This ENCYCLOPAEDIA OF MATHEMATICS aims to be a reference work for all parts of mathematics. It is a translation with updates and editorial comments of the Soviet Mathematical En­ cyclopaedia published by 'Soviet Encyclopaedia Publishing House' in five volumes in 1977 - 1985. The annotated translation consists of ten volumes including a special index volume. There are three kinds of articles in this ENCYCLOPAEDIA. First of all there are survey-...

This proceedings is composed of the papers resulting from the NATO work-shop "Perspectives in Ring Theory" and the work-shop "Geometry and Invariant The­ ory of Representations of Quivers" . Three reports on problem sessions have been induced in the part corresponding to the work-shop where they belonged. One more report on a problem session, the "lost" problem session, will be published elsewhere eventually. vii Acknowledgement The meeting be...
