Download Unlocking the Secrets of White Dwarf Stars Book in PDF, Epub and Kindle
White dwarfs, each containing about as much mass as our Sun but packed into a volume about the size of Earth, are the endpoints of evolution for most stars. Thousands of these faint objects have now been discovered, though only a century ago only three were known. They are among the most common stars in the Milky Way Galaxy, and they have become important tools in understanding the universe. Yet a century ago only three white dwarfs were known. The existence of these stars completely baffled the scientists of the day, and solving the mysteries of these strange objects required revolutionary advances in science and technology, including the development of quantum physics, the construction and utilization of large telescopes, the invention of the digital computer, and the ability to make astronomical observations from space. This book tells the story of the growth in our understanding of white dwarf stars, set within the context of the relevant scientific and technological advances. Part popular science, part historical narrative, this book is authored by one of the astrophysicists who participated directly in uncovering some of the secrets of white dwarf stars.

Download The Formative Years of Relativity Book in PDF, Epub and Kindle
First published in 1922 and based on lectures delivered in May 1921, Albert Einstein’s The Meaning of Relativity offered an overview and explanation of the then new and controversial theory of relativity. The work would go on to become a monumental classic, printed in numerous editions and translations worldwide. Now, The Formative Years of Relativity introduces Einstein’s masterpiece to new audiences. This beautiful volume contains Einstein’s insightful text, accompanied by important historical materials and commentary looking at the origins and development of general relativity. Hanoch Gutfreund and Jürgen Renn provide fresh, original perspectives, placing Einstein’s achievements into a broader context for all readers. In this book, Gutfreund and Renn tell the rich story behind the early reception, spread, and consequences of Einstein’s ideas during the formative years of general relativity in the late 1910s and 1920s. They show that relativity’s meaning changed radically throughout the nascent years of its development, and they describe in detail the transformation of Einstein’s work from the esoteric pursuit of one individual communicating with a handful of colleagues into the preoccupation of a growing community of physicists, astronomers, mathematicians, and philosophers. This handsome edition quotes extensively from Einstein’s correspondence and reproduces historical documents such as newspaper articles and letters. Inserts are featured in the main text giving concise explanations of basic concepts, and short biographical notes and photographs of some of Einstein’s contemporaries are included. The first-ever English translations of two of Einstein’s popular Princeton lectures are featured at the book’s end.

Download Astrophysics Is Easy Book in PDF, Epub and Kindle
Astrophysics is often –with some justification – regarded as incomprehensible without the use of higher mathematics. Consequently, many amateur astronomers miss out on some of the most fascinating aspects of the subject. Astrophysics Is Easy! cuts through the difficult mathematics and explains the basics of astrophysics in accessible terms. Using nothing more than plain arithmetic and simple examples, the workings of the universe are outlined in a straightforward yet detailed and easy-to-grasp manner. The original edition of the book was written over eight years ago, and in that time, advances in observational astronomy have led to new and significant changes to the theories of astrophysics. The new theories will be reflected in both the new and expanded chapters. A unique aspect of this book is that, for each topic under discussion, an observing list is included so that observers can actually see for themselves the concepts presented –stars of the spectral sequence, nebulae, galaxies, even black holes. The observing list has been revised and brought up-to-date in the Second Edition.

Download Green Fraud Book in PDF, Epub and Kindle
Marc Morano’s analysis of the proposed Green New Deal is eye-opening and damning. In his new book, Green Fraud: Why the New Green Deal Is Even Worse than You Think, Morano exposes the program as a far-left agenda filled with progressive policies disguised as a way to save the planet. No matter what the environmental scare-of-the-day may be, Morano says, the same solution is always proposed -- and that solution should scare us. Morano clearly shows how the Green New Deal will lay a path for “global governance,” resulting in less freedom, less sovereignty, massive government bureaucracy, and significant, crippling wealth redistribution. Drawing on past “new deals” to illustrate the impact such “deals” have on the United States, Morano will explain how FDR’s New Deal and Lyndon Johnson’s “Great Society” really impacted American society. And this latest big government program is no different. In Green Fraud, Morano reveals: How the Green New Deal’s objectives extend far beyond the environment -- including free college; “healthy food” for all; “safe, affordable, adequate housing” provided by the government; and other far-left agenda items That in Europe, where climate policies are years ahead of the United States, energy rationing, low economic growth, and rising costs are leading to misery and even death among Europeans How even Green New Deal allies such as the New York Times and Washington Post have outed the legislation as a wish-list of progressive policies How America can and must defeat the Green New Deal and restore sanity to the climate and energy policy discussion

Download Asymmetric Planetary Nebulae VII Book in PDF, Epub and Kindle
This book contains the best and most up-to-date contributions in the field of late stage stellar evolution, as presented at the APNVII conference in Hong Kong in December 2017. A total of 60 scientists from 20 countries gathered to present, listen, interact and discuss the most current issues and problems in planetary nebulae and related objects research. The emphasis of this influential series of meetings, which was the seventh occasion over the last 20 years, has always been on the hypothesized and observed physical shaping mechanisms of the ejected nebulae that have such wonderful and intriguing forms. This special Galaxies conference issue of fully refereed contributions brings together a representative compilation of the meeting presentations in paper form. It captures the current “snap shot” status of this research field in some real sense. Such proceedings are well received and can be used as a reference material by both participants and all others working in the field for years to come.

Download Symmetry in Special and General Relativity Book in PDF, Epub and Kindle
The development of special and general relativity has relied significantly on ideas of symmetry. Similarly, modern efforts to test these theories have often sought either violations or extensions of the symmetries seen, and symmetry is regularly used a tool in seeking new applications. In this Special Issue of symmetry, we explore some contemporary research related to symmetry in special and general relativity.

Download Asteroseismology Book in PDF, Epub and Kindle
Our understanding of stars has grown significantly due to recent advances in asteroseismology, the stellar analog of helioseismology, the study of the Sun's acoustic wave oscillations. Using ground-based and satellite observatories to measure the frequency spectra of starlight, researchers are able to probe beneath a star's surface and map its interior structure. This volume provides a wide-ranging and up-to-date overview of the theoretical, experimental and analytical tools for carrying out front-line research in stellar physics using asteroseismological observations, tools and inferences. Chapters from seven eminent scientists in residence at the twenty-second Canary Islands Winter School of Astrophysics examine the interior of our Sun relative to data collected from distant stars, how to measure the fundamental parameters of single field stars, diffusion processes, and the effects of rotation on stellar structures. The volume also provides detailed treatments of modeling and computing programs, providing astronomers and graduate students a practical, methods-based guide.
