Astrophysics is the physics of the stars, and more widely the physics of the Universe. It enables us to understand the structure and evolution of planetary systems, stars, galaxies, interstellar gas, and the cosmos as a whole. In this Very Short Introduction, the leading astrophysicist James Binney shows how the field of astrophysics has expanded rapidly in the past century, with vast quantities of data gathered by telescopes exploiting all parts of the electromagnetic spectrum, combined with the rapid advance of computing power, which has allowed increasingly effective mathematical modelling. He illustrates how the application of fundamental principles of physics - the consideration of energy and mass, and momentum - and the two pillars of relativity and quantum mechanics, has provided insights into phenomena ranging from rapidly spinning millisecond pulsars to the collision of giant spiral galaxies. This is a clear, rigorous introduction to astrophysics for those keen to cut their teeth on a conceptual treatment involving some mathematics.

Galaxies are the building blocks of the Universe: standing like islands in space, they are where the stars are born and where extraordinary phenomena can be observed. Many exciting discoveries have been made: how a supermassive black hole lurks at the centre of every galaxy, how enormous forces are released when galaxies collide, and what the formation of young galaxies can tell us about the mysteries of Cold Dark Matter. In this Very Short Introduction, renowned science writer John Gribbin describes the extraordinary things that astronomers are learning about galaxies, and explains how this can shed light on the origins and structure of the Universe.

Every atom of our bodies has been part of a star. Our very own star, the Sun, is crucial to the development and sustainability of life on Earth. This Very Short Introduction presents a modern, authoritative examination of how stars live, producing all the chemical elements beyond helium, and how they die, sometimes spectacularly, to end as remnants such as black holes. Andrew King shows how understanding the stars is key to understanding the galaxies they inhabit, and thus the history of our entire Universe, as well as the existence of planets like our own. King presents a fascinating exploration of the science of stars, from the mechanisms that allow stars to form and the processes that allow them to shine, as well as the results of their inevitable death.

The History of Astronomy: A Very Short Introduction

Astronomy, perhaps the first of the sciences, was already well developed by the time of Christ. Seventeen centuries later, after Newton showed that the movements of the planets could be explained in terms of gravitation, it became the paradigm for the mathematical sciences. In the nineteenth century the analysis of star-light allowed astrophysicists to determine both the chemical composition and the radial velocities of celestial bodies, while the development of photography enabled distant objects invisible to the human eye, to be studied and measured in comfort. Technical developments during and since the Second World War have greatly enlarged the scope of the science by permitting the study of radiation. This is a fascinating introduction to the history of Western astronomy, from prehistoric times to the origins of astrophysics in the mid-nineteenth century. Historical records are first found in Babylon and Egypt, and after two millennia the arithmetical astronomy of the Babylonians merged with the Greek geometrical approach to culminate in the Almagest of Ptolemy. This legacy was transmitted to the Latin West via Islam, and led to Copernicus's claim that the Earth is in motion. In justifying this Kepler converted astronomy into a branch of dynamics, leading to Newton's universal law of gravity. The book concludes with eighteenth- and nineteenth-century applications of Newton's law, and the first explorations of the universe of stars.

Black holes are a source of wide fascination. In this Very Short Introduction, Katherine Blundell addresses a variety of questions, including what a black hole actually is, how they are characterised and discovered, to what happens if you get too close to one. Explaining how black holes formand grow across cosmic time, as well as how many there are in the Universe, she also considers how black holes interact with matter - by stealing material that belongs to other stars, and how black holes give rise to quasars and other spectacular, yet exotic phenomena in outer space.

From the first, telescopes have made dramatic revelations about the Universe and our place in it. Galileo's observations of the Moon's cratered surface and discovery of Jupiter's four big satellites profoundly altered the perception of the heavens, overturning a two-thousand year cosmologythat held the Earth to be the centre of the Universe. Over the past century, the rapid development of computer technology and sophisticated materials allowed enormous strides in the construction of telescopes. Modern telescopes range from large Earth-based optical telescopes and radio arrays linkingup across continents, to space-based telescopes capturing the Universe in infrared, ultraviolet, X-rays, and gamma rays. In combination, they have enabled us to look deep into the Universe and far back in time, capturing phenomena from galactic collisions to the formation of stars and planetarysystems, and mapping the faint glow remaining from the Big Bang. In this Very Short Introduction, Dr. Geoff Cottrell describes the basic physics of telescopes, the challenges of overcoming turbulence and distortion from the Earth's atmosphere, and the special techniques used to capture X-rays and gamma rays in space telescopes. He explains the crucialdevelopments in detectors and spectrographs that have enabled the high resolution achieved by modern telescopes, and the hopes for the new generation of telescopes currently being built across the world.

Gravity

View: 7275

In this Very Short Introduction Timothy Clifton looks at the development of our understanding of gravity since the early observations of Kepler and Newtonian theory. He discusses Einstein's theory of gravity, which now supplants Newton's, showing how it allows us to understand why the frequency of light changes as it passes through a gravitational field, why GPS satellites need their clocks corrected as they orbit the Earth, and why the orbits of distant neutron stars speed up. Today, almost 100 years after Einstein published his theory of gravity, we have even detected the waves of gravitational radiation that he predicted. Clifton concludes by considering the testing and application of general relativity in astrophysics and cosmology, and looks at dark energy and efforts such as string theory to combine gravity with quantum mechanics.

Die Welt der Elementarteilchen

Dieses Buch handelt von Ideen, nicht von experimentellen oder theoretischen Methoden. Es ist ein Versuch zu zeigen, wie sich, nach den Entdeckungen dieses Jahrhunderts insbesondere im Bereich des sehr Kleinen, die Welt in den Augen des modernen Physikers darstellt. Natürlich werden einige wichtige Experimente beschrieben, aber im großen und ganzen wird darauf verzichtet, die komplizierten Metho den zu erörtern, die heute zur Untersuchung des Subatomaren ange wandt werden, um dafür um so ausführlicher auf die Struktur der Theorien und auf die Vorstellungen eingehen zu können, die die Grundlage unseres Verständnisses der Vorgänge bilden, die gegenwärtig die Front der physikalischen Forschung darstellen. Es bedürfte eines eigenen Buches, um den komplizierten und großartigen Geräten gerecht zu werden, die die Natur zwingen, unsere Fragen über die Welt der Elementarteilchen zu beantworten - ein Buch, das geschrieben werden sollte. Ich bitte den Leser dieses Buches zweierlei im Auge zu behalten . . Erstens, die Physik ist eine experimentelle Wissenschaft. Jede Theorie, jeder Begriff und jede Vorstellung über die Natur beruht letzten Endes auf experimentellen Tatbeständen, darauf, was in der Natur geschieht. Alle Abstraktionen und gedanklichen Konstruktionen haben kein ande res Ziel, als experimentelle Fakten in einfacher und übersichtlicher Weise zu beschreiben.

Water dominates the surface of Earth and is vital to life on our planet. It is a remarkable liquid which shows anomalous behaviour. In this Very Short Introduction John Finney introduces the science of water, and explores how the structure of water molecules gives rise to its physical and chemical properties. Considering water in all three of its states as ice and steam as well as liquid, Finney explains the great importance of an understanding of its structure and behaviour to a range of fields including chemistry, astrophysics, and earth and environmental sciences. Finney describes the role of water in biology, and ends with a discussion of the outstanding controversies concerning water, and some of the 'magical' properties which have been claimed for it.

„Ich habe ein Teilchen postuliert, das nicht entdeckt werden kann“, stellte der Physiker Wolfgang Pauli einst fest. Es brauchte lange Jahre, viel Geduld und großen Einfallsreichtum, um einen indirekten, flüchtigen Blick auf das schwer fassbare Neutrino zu erhaschen und jene Kiste Champagner zu gewinnen, die Pauli auf dessen Entdeckung gewettet hatte. Hier nun ist die Geschichte, wie dieses außergewöhnlichste aller Teilchen – ohne Ladung, fast ohne Masse, kaum mit Materie interagierend – gesucht und gefunden wurde und wie uns die Neutrino-Astronomie heute tiefe Einblicke in die Herzen ferner Galaxien ermöglicht.

Der Wandel eines faszinierenden, bedrohten Lebensraums Die Ozeane sind nicht nur der größte Lebensraum der Erde, sondern auch der am wenigsten erforschte. Die unermessliche Vielfalt dieses Ökosystems beginnen wir erst jetzt bis in die letzten Winkel zu begreifen – auch wie wichtig das Meer für unser Leben ist. Im letzten Jahrhundert hat jedoch die Herrschaft des Menschen über die Natur auch die Ozeane erreicht: Wir fischen die Meere leer und füllen sie stattdessen mit Umweltgiften. Tiefseebergbau droht den Lebensraum unzähliger Pflanzen und Tiere bis zur Unkenntlichkeit zu verändern. Die Klimaerwärmung ließ bereits ein Viertel aller Korallen zugrunde gehen. In seinem aufrüttelnden Buch beschreibt der Meeresbiologe und –schützer Callum Roberts den großen Reichtum der Ozeane und ihren Wandel, und er ruft dazu auf, der Zerstörung der Meere endlich Einhalt zu gebieten, denn noch ist es nicht zu spät.

E = mc2 ist die berühmteste Formel der Welt. Mit ihr brachte Einstein es auf den Punkt: Energie und Masse sind zwei Seiten derselben Medaille und die Lichtgeschwindigkeit c ist ihr Wechselkurs. Doch warum besteht dieses so einfache Verhältnis? Wie ist Albert Einstein zu diesem Schluss gekommen? Und welche Folgen für das Verständnis des Universums ergeben sich daraus? Brian Cox, Professor für Physik und in England durch seine Sendungen auf BBC sehr bekannt, hat sich zusammen mit seinem Kollegen Jeff Forshaw, Professor für theoretische Physik, die scheinbar einfache Einstein-Gleichung vorgenommen, um sie mit viel Energie ausführlich und verständlich zu erklären.
