The implications for cosmology, galactic and stellar evolution, dark matter research etc. are outlined and directions of future research are indicated.
Habent sua Jata colloquia. The present volume has its ongms in a spring 1984 international workshop held, under the auspices of the Israel Academy of Sciences and Humanities, by The Institute for the History and Philosophy of Science and Ideas of Tel-Aviv University in cooperation with The Van Leer Jerusalem Foundation. It contains twelve of the twenty papers presented at the workshop by the twenty-six participants. As Proceedings of conferences go, it is a good representative of the genre, sharing in the main characteristics of its ilk. It may even be one of the rare instances of a book of Proceed ings whose descriptive title applies equally well to the workshop's topic and to the interrelations between. the various papers it includes. Tension and Accommodation are the key words. Thus, while John Glucker's paper, 'Images of Plato in Late Antiqu ity, ' raises, by means of the Platonic example, the problem of interpreta tion of ancient texts, suggesting the assignment of proper weight to the creator of the tradition and not only to his many later interpreters in assessing the proper relationship between originator and commentators, Abraham Wasserstein's 'Hunches that did not come off: Some Prob lems in Greek Science' illustrates the long-lived Whiggish tradition in the history of science and mathematics. As those familiar with my work will undoubtedly note, Wasserstein's position is far removed from my stance on ancient Greek mathematics."
With full color illustrations. This TR is actually a textbook on atmospheric entry for several classes at AFIT. It teaches from an analytical perspective, with finding closed-form solutions being the preferred approach. The over-arching goal is to instill and understand how families of solutions behave as well as the general trends, trade-offs, and the nature of atmospheric entry before picking point designs to study in detail. By thoroughly understanding the classic analytic analyses first, we can better use the computer to solve the hard problems. The book's approach is to use easily visualized variables to solve the analytical problems first and keep them (more-or-less) consistent as we move to the computer. This is a back to the basics approach for a new generation of students who've become more comfortable with numerical solutions than analytical ones. The pages are loaded with equations because the details of many of the derivations are included. This book pulls together many classical analyses and presents them in a consistent notation for the first time. It provides a convenient starting point for an analytical understanding of atmospheric entry, with plenty of references to those original works. It ties together results that were originally published years apart by different authors. And, peppered throughout, you'll find some new approaches and results.
This edited volume discusses how even small nation states can make a significant difference in the future of space governance. The book is divided into three main sections covering political theory, case studies, and space technology and applications. Key topics of discussion include planetary defense, space mining, and high-power systems in space. Through these timely subjects, the book presents strategies for developing a truly global governance framework in space, based on the concept of a responsible cosmopolitan state. Authored by a multidisciplinary group of researchers from the Czech Republic, the volume will appeal to other scientific teams and policymakers looking to become pioneers of cosmopolitan space policies at a national and global level.
Turbulence is a research field where high expectations have met with recurrent frustration. It is a common perception among physicists, mathematicians and engineers that there is a "big mystery" behind the phenomenon of turbulence. Its history has also remained anything but well researched. Unlike topics such as quantum theory, which began to attract physics historians as long as fifty years ago, turbulence has - until now - received only little professional historical investigation. In this book, which complements his earlier SpringerBrief "The Turbulence Problem", the author sketches the history of turbulence from the vantage point of its roots (Part I), the basic concepts (Part II) and the formation of a scientific community that regarded turbulence as a research field in its own right (Part III). From this perspective turbulence research appears to undertake an odyssey through uncharted territories. The book follows this development up until a conference in Marseille in the year 1961, which marked the inauguration of turbulence in the words of its organizer as "a new science". The epilogue contains some observations about turbulence research since 1961. This book provides a rich source of information for all those interested in the history of this major field of basic and applied science.
While there are many biographies of JFK and accounts of the early years of US space efforts, this book uses primary source material and interviews with key participants to provide a comprehensive account of how the actions taken by JFK's administration have shaped the course of the US space program over the last 45 years.

This book is intended as an overview at an undergraduate or early university level and describes the effects of spaceflight at cellular and organism levels. Past, current, and future research on the effects of gravity - or its absence - and ionizing radiation on the evolution, development, and function of living organisms is presented in layman's terms by researchers who have been active in this field. The purpose is to enlighten science and non-science readers to the benefits of space biology research for conducting basic and applied research to support human exploration of space and to take advantage of the space environment as a laboratory for scientific, technological, and commercial research. The first chapters present an overview of the major focuses of space research in biology, as well as the history and the list of animals and plants that have flown in space to date.
Since 1967, the most prominent events of a General Assembly of the International Astronomical Union have been published in a separate volume. The "Highlight of Astronomy" (Volume 9) reports on the major scientific presentations made at the XXIst General Assembly July 23 August 1, 1991, Buenos Aires, Argentina. The present volume contains the text of the three invited Discourses and of the papers presented during seven Joint Discussion Meetings and eight Joint Commission Meetings.
Professor Zdenek Kopal is sixty-seven this year even though his scientific activity, enthusiasm and springy step hardly betray the ad- vancement in years. He carne to Manchester as Professor of Astronomy thirty years ago after a very fruitful association of fourteen years with the Harvard Observatory. Much impressed with the young man, Harlow Shapley, who with characteristic insight had recognised in Kopal the qualities that have since made him an outstanding leader in ec1ipsing binary research, had invited him over as a Research Associate. In the subsequent decade Kopal set about the task of introducing analytical rigour in the solution of orbit al elements that hitherto had depended ex- c1usively on the semigraphical procedures introduced by Russell and exploited fully by Shapley. These first efforts stimulated publication of the first of his many books on ec1ipsing variables; the Introductian ta the Study of Ec/ipsing Variables summarized these iterative methods and remains a c1assic in this field. Soon after the appearance of this volume in print, Kopal gave a course on this subject for the graduate students at Harvard. I was one of those who had the opportunity to attend it and learn much on the need of care and precision in the practice of photoelectric photometry and the importance of exploiting such data to the fullest extent with methods of increasing resolving power.
This volume contains papers presented at the US/European Celestial Mecha nics Workshop organized by the Astronomical Observatory of Adam Mickiewicz University in Poznan, Poland and held in Poznan, from 3 to 7 July 2000. The purpose of the workshop was to identify future research in celestial mech anics and encourage collaboration among scientists from eastem and westem coun tries. There was a full program of invited and contributed presentations on selected subjects and each day ended with a discussion period on a general subject in celestial mechanics. The discussion topics and the leaders were: Resonances and Chaos-A. Morbidelli; Artificial Satellite Orbits-K. T. Alfriend; Near Earth Ob jects - K. Muinonen; Small Solar System Bodies - I. Williams; and Summary - P. K. Seidelmann. The goal of the discussions was to identify what we did not know and how we might further our knowledge. The size of the meeting and the language differences somewhat limited the real discussion, but, due to the excellence of the different discussion leaders, each of these sessions was very interesting and productive. Celestial Mechanics and Astrometry are both small fields within the general subject of Astronomy. There is also an overlap and relationship between these fields and Astrodynamics. The amount of interaction depends on the interest and efforts of individual scientists."

This volume is the outgrowth of several international meetings to discuss a vision for the future of solar radio physics: the development of a new radio instrument. From these discussions, the concept for the Frequency Agile Solar Radiotelescope (FASR) was born. Most of the chapters of this book are based oninvitedtalksattheFASRScienceWorkshop, heldinGreenbank, WVinMay 2002, and a special session on Solar and Space Weather Radiophysics held at the 200th American Astronomical Society meeting held in Albuquerque, NM in June 2002. Although many of the chapters deal with topics of interest in planning for FASR, other topics in Solar and Space Weather Radiophysics, such as solar radar and interplanetary scintillation, are covered to round out the discipline. The authors have been asked to write with a tutorial approach, to make the book useful to graduate students and scientists new to radio physics. This book is more than a compilation of FASR science topics. The FASR instrument concept is so revolutionary-by extending capability by an order of magnitude in several dimensions at once (frequency coverage, spatial reso- tion, dynamicrange, timeresolution, polarizationprecision)-thatitchallenges scientiststothinkinnewways.

The XIXth General Assembly of the International Astronomical Union was held in New Delhi, India, from November 19 to 28, 1985. It was dedicated to the memory of a former IAU President, Professor M. K. V. Bappu, who tragically passed away on August 19, 1982. On the occasion of the Delhi General Assembly, the IAU Minor Planet Center announced that Minor Planet (asteroid) No. 2596 henceforth will carry the name Vainu Sappu. The full text of the announcement reads: "(2596) VAINU BAPPU = 1979 KN (diameter about 8 kilometers, period 5 years 4 months, mean distance from the Sun around 450 million kilometers) Discovered 1979, May 19, by R.

The International Conference on the History of Original Ideas and Basic Discoveries, held at the "Ettore Majorana" Centre for Scientific Culture in Erice, Sicily, July 27-August 4, 1994, brought together sixty of the leading scientists including many Nobel Laureates in high energy physics, principal contributors in other fields of physics such as high Tc superconductivity, particle accelerators and detector instrumentation, and thirty-six talented younger physicists selected from candidates throughout the world. The scientific program, including 49 lectures and a discussion session on the "Status and Future Directions in High Energy Physics" was inspired by the conference theme: The key experimental discoveries and theoretical breakthroughs of the last 50 years, in particle physics and related fields, have led us to a powerful description of matter in terms of three quark and three lepton families and four fundamental interactions. The most recent generation of experiments at e+e- and proton-proton colliders, and corresponding advances in theoretical calculations, have given us remarkably precise determinations of the basic parameters of the electroweak and strong interactions. These developments, while showing the striking internal consistency of the Standard Model, have also sharpened our view of the many unanswered questions which remain for the next generation: the origin and pattern of particle masses and families, the unification of the interactions including gravity, and the relation between the laws of physics and the initial conditions of the universe.
A. GENERAL BACKGROUND "The foremost goal of the international community in the area [of private space launch services] should be to induce states to implement effective licensing procedures applicable to commercial ventures for which state responsibility may 1 exist. " 1. PRIVATE SECTOR PARTICIPATION IN THE SPACE INDUSTRY In the first decades of the space age, military and state security motivations indicated the direction of national space programs. Now the development of space activities depends essentially upon the possibility of recovering 2 investments. Private sector-driven commercial endeavors in outer space have been increasing exponentially and have experienced a significant quantitative growth over the last years. Spacefarers promote commercial participation of private companies in operations related to outer space, and, thus, the private sector is now increasingly providing satellite telecommunications, remote sensing, global positioning and space launch services directly to its customers. In this context, overall revenues for the worldwide space industry 3 amounted to US$ 82 billion in 2001. In the late 1990's the transponder demand, in particular Ku- band transponders, was consistently on the rise due 4 to the escalated utilization of geostationary satellite transponders. Global positioning systems have been playing an increasingly important role in navigation, and remote sensing systems are mapping and documenting nearly 1 E. A. Frankle & E. J.

This Open Access book gives a comprehensive account of both the history and current achievements of molecular beam research. In 1919, Otto Stern launched the revolutionary molecular beam technique. This technique made it possible to send atoms and molecules with well-defined momentum through vacuum and to measure with high accuracy the deflections they underwent when acted upon by transversal forces. These measurements revealed unforeseen quantum properties of nuclei, atoms, and molecules that became the basis for our current understanding of quantum matter. This volume shows that many key areas of modern physics and chemistry owe their beginnings to the seminal molecular beam work of Otto Stern and his school. Written by internationally recognized experts, the contributions in this volume will help experienced researchers and incoming graduate students alike to keep abreast of current developments in molecular beam research as well as to appreciate the history and evolution of this powerful method and the knowledge it reveals.
This book aims to make Galileo Galilei (1564-1642) accessible to the modern reader by refashioning the great scientist's masterpiece Discourses and Mathematical Demonstrations Relating to Two New Sciences in today's language. Galileo Galilei stands as one of the most important figures in history, not simply for his achievements in astronomy, physics, and engineering and for revolutionizing science and the scientific method in general, but also for the role that he played in the (still ongoing) drama concerning entrenched power and its desire to stifle any knowledge that may threaten it. Therefore, it is important that today's readers come to understand and appreciate what Galilei accomplished and wrote. But the mindset that shapes how we see the world today is quite different from the mindset -- and language -- of Galilei and his contemporaries. Another obstacle to a full understanding of Galilei's writings is posed by the countless historical, philosophical, geometrical, and linguistic references he made, along with his often florid prose, with its blend of Italian and Latin. De Angelis' new rendition of the work includes translations of the original geometrical figures into algebraic formulae in modern notation and allows the non-specialist reader to follow the thread of Galileo's thought and in a way that was barely possible until now.
In order to outline possible future directions in galaxy research, this book wants to be a short stopover, a moment of self-reflection of the past century of achievements in this area. Since the pioneering years of galaxy research in the early 20th century, the research on galaxies has seen a relentless advance directly connected to the parallel exponential growth of new technologies. Through a series of interviews with distinguished astronomers the editors provide a snapshot of the achievements obtained in understanding galaxies. While many initial questions about their nature have been addressed, many are still open and require new efforts to achieve a solution. The discussions may reveal paradigms worthwhile revisiting. With the help of some of those scientists who have contributed to it, the editors sketch the history of this scientific journey and ask them for inspirations for future directions of galaxy research.
Near-infrared astronomy has become one of the most rapidly developing branches in modern astrophysics. Innovative observing techniques, near-infrared detectors with quantum efficiencies in excess of 90%, highly specialised instruments as well as advanced data reduction techniques have allowed major breakthroughs in various areas like exoplanets, star-forming regions, the supermassive black hole in the Galactic center, and the high-redshift Universe. In this book, the reader will be introduced to the basic concepts of how to prepare near-infrared observations with maximized scientific return. Equal weight is given to all aspects of the data reduction for both - imaging and spectroscopy. Information is also provided on the state of the art instrumentation available and planned, on detector technology or the physics of the atmosphere, all of which influence the preparation and execution of observations and data reduction techniques. The beginner but also the expert will find a lot of information in compact form which is otherwise widely dispersed across the internet or other sources. |
