Relativity: A Very Short Introduction

by Russell Stannard

If you move at high speed, time slows down, space squashes up and you get heavier. Travel fast enough and you could weigh as much as a jumbo jet, be flattened thinner than a CD without feeling a thing--and live forever! As for the angles of a triangle, they do not always have to add up to 180 degrees. And then, of course, there are black holes. These are but a few of the extraordinary consequences of Einstein's theory of relativity. It is now over a hundred years since he made these discoveries, and yet the general public is still largely unaware of them. Filled with illuminating anecdotes and fascinating accounts of experiments, this book aims to introduce the interested lay person to the subject of relativity in a way which is accessible and engaging and at the same time scientifically rigorous. With relatively few mathematical equations--nothing more complicated than the Pythagoras's Theorem--this VSI packs a lot time into very little space, and for anyone who has felt intimidated by Einstein's groundbreaking theory, it offers the perfect place to start.

Relativity: An Introduction to Spacetime Physics

Relativity: The Special And General Theory (Routledge Great Minds)

by Albert Einstein

Time magazine's "Man of the Century", Albert Einstein is the founder of modern physics and his theory of relativity is the most important scientific idea of the modern era. In this short book, Einstein explains, using the minimum of mathematical terms, the basic ideas and principles of the theory that has shaped the world we live in today. Unsurpassed by any subsequent books on relativity, this remains the most popular and useful exposition of Einstein's immense contribution to human knowledge. With a new foreword by Derek Raine.

Relativity: The Special and the General Theory

by Roger Penrose Albert Einstein

Robert Geroch builds on Einstein's work with commentary that addresses the ideas at the heart of the theory, bringing a modern understanding of relativity to the text. He elucidates how special relativity is a reconciliation of the contradictions between the nature of light and the principle of relativity; he expands on Einstein's treatment of the geometry of space-time and the fundamental notion of an "event"; he explains in detail, but without technical language, the equivalence of inertial and gravitational mass, a cornerstone of general relativity.

Relativity: The Special and the General Theory - 100th Anniversary Edition (Classic Reprint Ser.)

Intended for a popular audience, the book remains one of the most lucid explanations of the special and general theories ever written. This edition of Einstein’s celebrated book features an authoritative English translation of the text along with commentaries by Hanoch Gutfreund and Jürgen Renn that examine the evolution of Einstein’s thinking and cast his ideas in a modern context. Providing invaluable insight into one of the greatest scientific minds of all time, the book also includes a unique survey of the introductions from past editions, covers from selected early editions, a letter from Walther Rathenau to Einstein discussing the book, and a revealing sample from Einstein’s original handwritten manuscript.

Relativität der Evolution

by Markus Knoflacher

Dieses Werk fokussiert vor allem auf evolutionäre Prozesse (und weniger auf evolutionäre Geschichte). Themen sind abiotische Rahmenbedingungen, Morphologie und Physiologie lebender Organismen, fossile und molekulare Hinweise auf evolutionäre Entwicklungen. Die grundlegenden Prozesse biologischer Evolution sind bereits in einzelligen Organismen festgelegt. Entwicklungsoptionen für vielzellige Organismen ergeben sich vereinfacht durch die nutzbaren energetischen Umwandlungspotenziale und die Dynamik der abiotischen und biotischen Wechselwirkungen. Evolutionsprozesse vielzelliger Organismen sind deshalb überwiegend durch die Bedingungen der umgebenden Systeme bedingt. Am deutlichsten zeigen dies Vergleiche der evolutionären Entwicklung von Wirbeltieren unter marinen und terrestrischen Bedingungen.Allein aus Effizienzgründen kann keine einzige Art die Ausstattung für die Erfassung und langfristig nachhaltige Gestaltung der umgebenden Systeme besitzen. Abhängig von den verfügbaren energetischen Umwandlungspotenzialen ist eine einzelne Art sehr wohl in der Lage die umgebenden Systeme zu verändern – allerdings ohne die daraus resultierenden langfristigen Folgewirkungen erfassen zu können. Daraus ergeben sich grundsätzlich neue Fragestellungen für die Gestaltung und Grenzen eines langfristig sinnvollen gesellschaftlichen Handelns.

Relentless Evolution

by John N. Thompson

At a glance, most species seem adapted to the environment in which they live. Yet species relentlessly evolve, and populations within species evolve in different ways. Evolution, as it turns out, is much more dynamic than biologists realized just a few decades ago. In "Relentless Evolution," John N. Thompson explores why adaptive evolution never ceases and why natural selection acts on species in so many different ways. Thompson presents a view of life in which ongoing evolution is essential and inevitable. Each chapter focuses on one of the major problems in adaptive evolution: How fast is evolution? How strong is natural selection? How do species co-opt the genomes of other species as they adapt? Why does adaptive evolution sometimes lead to more, rather than less, genetic variation within populations? How does the process of adaptation drive the evolution of new species? How does coevolution among species continually reshape the web of life? And, more generally, how are our views of adaptive evolution changing? "Relentless Evolution" draws on studies of all the major forms of life from microbes that evolve in microcosms within a few weeks to plants and animals that sometimes evolve in detectable ways within a few decades. It shows evolution not as a slow and stately process, but rather as a continual and sometimes frenetic process that favors yet more evolutionary change. "

Reliability Growth: Enhancing Defense System Reliability

by Panel on Reliability Growth Methods for Defense Systems

A high percentage of defense systems fail to meet their reliability requirements. This is a serious problem for the U. S. Department of Defense (DOD), as well as the nation. Those systems are not only less likely to successfully carry out their intended missions, but they also could endanger the lives of the operators. Furthermore, reliability failures discovered after deployment can result in costly and strategic delays and the need for expensive redesign, which often limits the tactical situations in which the system can be used. Finally, systems that fail to meet their reliability requirements are much more likely to need additional scheduled and unscheduled maintenance and to need more spare parts and possibly replacement systems, all of which can substantially increase the life-cycle costs of a system. Beginning in 2008, DOD undertook a concerted effort to raise the priority of reliability through greater use of design for reliability techniques, reliability growth testing, and formal reliability growth modeling, by both the contractors and DOD units. To this end, handbooks, guidances, and formal memoranda were revised or newly issued to reduce the frequency of reliability deficiencies for defense systems in operational testing and the effects of those deficiencies. "Reliability Growth" evaluates these recent changes and, more generally, assesses how current DOD principles and practices could be modified to increase the likelihood that defense systems will satisfy their reliability requirements. This report examines changes to the reliability requirements for proposed systems; defines modern design and testing for reliability; discusses the contractor's role in reliability testing; and summarizes the current state of formal reliability growth modeling. The recommendations of "Reliability Growth" will improve the reliability of defense systems and protect the health of the valuable personnel who operate them.
