This book seeks to truthfully examine the facts that scientists have discovered about the origin of the universe and the beginning of life. Using this information the cases for creation and evolution are discussed with an open mind. The scientific evidence on the subject is recorded. The flaws in some claims are exposed. The readers can therefore form their own opinion on the scientists' interpretation of the facts. Using Christian and Non-Christian historical sources the Christian Churches' beliefs are examined to determine the reliability of the churches' teaching.
The techniques of visual, photographic and photoelectric measurement of variable stars are accompanied by specific examples of the type of scientific results that can be and have been obtained.
Proceedings from the Second Trieste Colloquium on Astrophysics, September 12-17, 1968
A strange field of speculation is opened by this phenomenon ... here we have a star fitfully variable to an astonishing extent. and whose fluctuations are spread over centuries. apparently in no settled period. and with no regularity of progression. What origin can we ascribe to these sudden flashes and relapses? What conclusions are we to draw as to the comfort or habitability of a system depending for its supply of light and heat on so uncertain a source? -- J. F. W. Herschel! We can imagine, at least, that the study of Luminous Blue Variable stars began as the official court astrophysicists of Eridu speculated about a new 5000 years ago first-magnitude star which persisted in their southe...
A reference for astronomers and historians on astronomical spectroscopy, from the discovery of spectral lines through to the year 2000.
McMahon looks at what the future is for diversity and our species in particular, in his book which celebrates our evolution since our emergence as a species as described in Charles Darwin's 'On the Origin of Species'.
Authored by ESO senior advisor Claus Madsen, the present book comprises 576 action-packed pages of ESO history and dramatic stories about the people behind the organisation. This is the ultimate historical account about ESO and its telescopes in the southern hemisphere, but also about a truly remarkable European success story in research. Spanning the range from the first telescopes to the future platforms of the next generation, it shows how the improvement of the telescopes leads to a continuously changing view of the Universe. With 150 photos and illustrations. Produced especially for ESO's 50th anniversary.
The organization of this Symposium had its beginnings at the International Astronomical Union General Assembly in Grenoble in 1976. The initial "rounding up" of the Scienti fic Organizing Committee was begun by Drs. Snow and Swings; most of us who became the eventual organizing committee met a few times during the Assembly and formulated the essential outlines of the meeting. Extensive correspondence with all the committee subsequently established the program. The idea was to bring together both observers and theoreticians to discuss the stellar winds and mass loss rates and their effects on evolutions of O-type stars. On the observational side, there are now spectroscopic data from the far UV to the near IR regions concerning the stellar winds. There is also information about the free-free emission in the wind from the IR and radio portions of the spectrum. Fortunately, these different detection methods give more or less the same mass loss rate for the one star, s Pup" which has been observed at all wavelengths. One of the intents of the first three sessions of this Symposium is to outline the eXisting data on mass loss rates as it per tains to the O-type stars.
Stellar photometry from space, automatic photometric telescopes, and CCD photometers, these are just some of the exciting areas of current interest and future developments in stellar photometry covered in this timely review. Articles from international experts - drawn together at the IAU Colloquium 136, in Dublin, 1992 - are gathered here to cover all aspects of this fundamental technique. In this survey, professionals discuss state-of-the-art and future technology including photometry with millimagnitude accuracy, multichannel arrays used in the optical and IR, a global network of automatic photometric telescopes, time-series photometry of faint sources using CCDs, and photometry from space. These articles provide an up-to-date account of all aspects of photometry and a guide to future developments - an essential survey for professionals involved in the design and use of such instruments.
A TurkÕs discovery that Armenians once thrived in his hometown leads to a groundbreaking investigation into the local dynamics of genocide. mit Kurt, born and raised in Gaziantep, Turkey, was astonished to learn that his hometown once had a large and active Armenian community. The Armenian presence in Aintab, the cityÕs name during the Ottoman period, had not only been destroyedÑit had been replaced. To every appearance, Gaziantep was a typical Turkish city. Kurt digs into the details of the Armenian dispossession that produced the homogeneously Turkish city in which he grew up. In particular, he examines the population that gained from ethnic cleansing. Records of land confiscation and...
