Download or read book Stellar Formation written by V C Reddish and published by Elsevier. This book was released on 2013-10-22 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stellar Formation brings together knowledge about the formation of stars. In seeking to determine the conditions necessary for star formation, this book examines questions such as how, where, and why stars form, and at what rate and with what properties. This text also considers whether the formation of a star is an accident or an integral part of the physical properties of matter. This book consists of 13 chapters divided into two sections and begins with an overview of theories that explain star formation as well as the state of knowledge of star formation in comparison to stellar structure and evolution. The places in which stars are forming are then analyzed by focusing on the distributions of very young stars, globules, and cloud fragments. The relationship between the distributions of stars and interstellar clouds is also considered. The chapters that follow explore the frequency distribution of stellar masses as well as the masses of aggregates of stars and interstellar clouds. The reader is also introduced to the rate and environment of star formation; the cloud-like structure of the interstellar gas; the ordering of interstellar clouds into spiral arms; and the conditions under which a cloud will contract until it is set inevitably on the route to becoming a star. The remaining chapters examine the fragmentation of clouds into protostars and the evolution of galaxies. This text will be of interest to students and practitioners of astronomy.
Download or read book Helpless as a Baby written by J. D. Waters and published by AuthorHouse. This book was released on 2022-04-20 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book starts with a paradox and ends with a riddle. The paradox notes that the mammal specie with the most capable adults is the mammal specie with the most helpless of babies. Is there a connection? The author contends that there is. He attempts to show how the evolution of the helpless baby has led to reciprocal genetic and behavioural adaptions of the nursing females. In addition, the increasing length of the baby's helplessness resulted in the development of the hominid multi-age brood. The author shows how the Long and Short Birth Interval multi-age broods led to social sharing, unified teamwork, speech, language; and civilisation.

Download or read book Timeless Vision written by Jim Johnson and published by BrownBooks.ORM. This book was released on 2024-04-12 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Faith and facts are reconciled in this revelatory examination of biblical and secular truths that follows the path to God through science, not around it. Always a man of science, Jim Johnson accepted Christ into his life shortly after his fiftieth birthday. This acceptance of God’s unseeable power did not shake his belief in science—it strengthened it. Through years of research on the world’s evolution, Johnson found that in studying every new hypothesis and theory, he believes even more in God’s universal role. Timeless Vision: Understanding God’s Creation through the Lens of Science bridges the gap between faith and science. Johnson examines the natural progression of Earth’s creation alongside the seven biblical days, explains the conundrum of time, and expands upon the ever-evolving relationship humanity has with science and religion. Through analyzing scripture with detailed data and using science to bolster Christian beliefs, Johnson reveals just how rare and privileged Earth and human life truly are. It is through studying science and faith together, not apart, that we can see how God’s plan was developed and why He did it. One is not complete without the other. Let Johnson lead you down the path less traveled—the one of science and faith—and show how God gave humanity these ways to discover Him more fully and completely.

Download or read book Galactic Astrophysics and Gamma Ray Astronomy written by G.E. Morfill and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the invited and contributed lectures presented at a meeting organised in the context of the XVIII general assembly ofthe IAU, held in Patras, August 19, 1982. Roughly one hundred scientists attended this meeting, the discussions were livel- sometimes heated - and the original time span allocated to the meeting was as a result, comfortably exceeded by about 50 % . The aim of this meeting was to determine the role of galactic gamma-ray astronomy within the general concept of galactic astrophysics. The timing, at the end of the COS-B mission, was regarded as opportune, because it gives interested astrophysicists the possibility for interdisciplinary studies using the existing gamma-ray data base (e.g. comparison with infrared, radio, X-ray, etc. astronomies), as well as for theoretical studies. The next generation of gamma-ray detectors will probably not be in operation for another 5 to 10 years, and therefore it is hoped that the proceeding of this meeting can be used (in the intermediate time) as a basis for further studies, as a stimulation for more theoretical work and as an important contribution for defining the aims and operation of future gamma-ray missions. The interrelationship with other branches of astronomy, the astrophysical implications and the study of relevant physical processes using available measurements in the near-Earth environment were important results of the meeting. Many persons contributed to the success of the meeting, in particular all those who either presented a contribution and/or took part in the discussions.

Download or read book Origin of Life written by Y. Wolman and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 602 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is a record of the 6th International Conference on the Origins of Life and the 3rd Meeting of the International Society for the Study of the Origins of Life. The conference was held under the auspices of the Israel Academy of Sciences and Humanities at Jerusalem from June 22nd to June 27th 1980. A few weeks prior to the conference, Academician Aleksander Ivanovich Oparin passed away. Oparin, the father and founder of the study of the origins of life, proposed over 50 years ago that modern biological molecules had abidogical origins in the past, thus the beginning of life on Earth was preceded by a long period of abiogenic molecular evolution. Oparin was planning to report on his latest work in the opening session of the meeting - "Natural Selection: A Leading Factor in Transition from the Non-Living Matter to Life". This lecture will never be delivered. In Hebrew we say of those who have died "may their memory be bound with the bonds of eternal life". For Aleksander Ivanovich Oparin those words have particular significance, for surely his pioneering work will endure as long as the spirit of scientific enquiry prevails. This meeting was dedicated to the memory of Aleksander Ivanovich Oparin.
