R750 Discovery Miles 7 500 Ships in 10 - 15 working days

The development of man's understanding of planetary motions is the crown jewel of Newtonian mechanics. This book offers a concise but self-contained handbook-length treatment of this historically important topic for students at about the third-year-level of an undergraduate physics curriculum. After opening with a review of Kepler's three laws of planetary motion, it proceeds to analyze the general dynamics of "central force" orbits in spherical coordinates, how elliptical orbits satisfy Newton's gravitational law and how the geometry of ellipses relates to physical quantities such as energy and momentum. Exercises are provided and derivations are set up in such a way that readers can gain analytic practice by filling in missing steps. A brief bibliography lists sources for readers who wish to pursue further study on their own.

Have you ever wondered what comets are and why astronomers spend so much time studying them? Now, a comet expert and an astronomical historian have come together to produce this unique book. Using their several decades of teaching experience, the authors have concisely presented the information you need to comprehend these majestic apparitions that grace our night skies. No mathematical proficiency is needed. In fact, this book doesn't contain a single equation. Comets are cosmic Rosetta stones, bridging our current knowledge by digging back to the earliest days of our solar systems. How did life arise on Earth? Did comets play a significant role in bringing water and the necessary organic matter to our early Earth? How about the dinosaurs? Were they driven to extinction by a cometary impact 66 million years ago? Comets may be both the enablers and destroyers of life on Earth as we know it. These are some of the tantalizing questions discussed here. If you so desire, steps are given to join the ranks of amateur comet hunters. Astronomy is one of the last sciences where amateurs play a significant role. Your reward for discovery? A comet officially bearing your name in the history books. The next great comet is on its way, we just do not know when it will arrive. Armed with this book, you will be ready to enjoy this unforgettable event.

Yutaka Hirai
R3,785 Discovery Miles 37 850 Ships in 18 - 22 working days

This book addresses the mechanism of enrichment of heavy elements in galaxies, a long standing problem in astronomy. It mainly focuses on explaining the origin of heavy elements by performing state-of-the-art, high-resolution hydrodynamic simulations of dwarf galaxies. In this book, the author successfully develops a model of galactic chemodynamical evolution by means of which the neutron star mergers can be used to explain the observed abundance pattern of the heavy elements synthesized by the rapid neutron capture process, such as europium, gold, and uranium in the Local Group dwarf galaxies. The book argues that heavy elements are significant indicators of the evolutionary history of the early galaxies, and presents theoretical findings that open new avenues to understanding the formation and evolution of galaxies based on the abundance of heavy elements in metal-poor stars.

The Story of Our Amazing Universe (Hardcover): Athar Shareef The Story of Our Amazing Universe (Hardcover)
Athar Shareef
R914 Discovery Miles 9 140 Ships in 10 - 15 working days

Our Universe is amazing. This is its story, told in simple language. The story tells how the Universe came to be what it is today. It starts with the Big Bang and describes how stars, black holes, and our solar system developed. It explores the evolution of life on Earth and investigates the possibility of extra-terrestrial life. It peers into the future and wonders about the Universe's likely old age and death, or whatever else may be its end. The challenge the book takes up is to explain all of this, including some of the astonishing concepts we have in science, such as Einstein's theories of Relativity and Quantum Mechanics, using virtually no mathematics and without dumbing-down. All are described narratively and explained using examples and anecdotes. The book is written for young people with a thirst for learning about the science of space, as well as for 'grown-ups' who want a better understanding of this fascinating subject.

The Shadow of the Black Hole (Hardcover): John W. Moffat The Shadow of the Black Hole (Hardcover)
John W. Moffat
R760 Discovery Miles 7 600 Ships in 10 - 15 working days

Black holes entered the world of science fiction and films in the 1960s, and their popularity in our culture remains today. The buzz surrounding black holes was and is due, in large part, to their speculative nature. It is still difficult for the general public to determine fact versus fiction as it pertains to this terrifying idea: something big enough to swallow anything and everything in close proximity, with a gravitational force so strong that nothing, including light, can escape. In the fall of 2015, scientists at the Laser Interferometry Gravitational-Wave Observatory (LIGO) detected the first sounds from black holes, brought to earth by the gravitational waves that emitted from the merging of two black holes 1.4 billion light years away in space. This confirmed the existence of gravitational waves, which Albert Einstein predicted in 1916. In the spring of 2017, physicists and astronomers who were working on the Event Horizon Telescope (EHT) project captured the first image of a black hole. This was the supermassive black hole hosted by the galaxy M87 in the constellation Virgo, 53 million light years away, and the image shows the shadow the black hole casts upon the bright light surrounding it. In this book, John Moffat shares the history of black holes and presents the latest research into these mysterious celestial objects, including the astounding results from gravitational wave detection and the shadow of the black hole.

Explaining Lithium Enriched Red Giant Branch Stars (Hardcover, 1st ed. 2018): Claudia Aguilera-Gomez Explaining Lithium Enriched Red Giant Branch Stars (Hardcover, 1st ed. 2018)
Claudia Aguilera-Gomez
R2,653 Discovery Miles 26 530 Ships in 18 - 22 working days

This thesis provides new insights into the seemingly anomalous ubiquity of lithium-rich red giant stars. The theory of stellar evolution, one of the most successful models of modern astrophysics, predicts that red giant stars should display negligible levels of lithium (Li) on their surfaces. However, Li-rich giants, defined as those showing more than three times the Li content of the Sun, are found everywhere astronomers look in apparent defiance of established theory. The author addresses this problem, analyzing the different possible explanations for such an anomaly, which include interaction with a binary companion, the production of Li in the interior of the star with its subsequent transport to stellar exteriors, and the stellar interaction with planets. The author focuses on this last possibility, where the Li enrichment may be due to the ingestion of planets or brown dwarfs as the stars in question grew in size while becoming giants. She shows that this process is indeed able to explain an important fraction of giants with Li levels above the three times solar threshold, but that some other mechanism is needed to explain the remaining fraction. While this is an important discovery in its own right, the result that makes this thesis groundbreaking is its demonstration that the threshold between Li-normal and Li-rich is mass dependent rather than a fixed proportion of the Sun's content. This corrects a fundamental misapprehension of the phenomenon and opens up a new framework in which to understand and solve the problem. Finally, the author presents interesting observational applications and samples with which to test this new approach to the problem of Li enrichment in giants.

This book highlights a major advance in low-energy scattering theory: the Multi-Channel Algebraic Scattering (MCAS) theory, which represents an attempt to unify structure and reaction theory. It solves the Lippmann-Schwinger equations for low-energy nucleon-nucleus and alpha-nucleus scattering in momentum space, allowing both the bound and scattering states in the compound nucleus formed to be described. Results of various cases are presented and discussed.

Project Space Station - Plans for a Permanent Manned Space Station (Paperback): Brian O'Leary Project Space Station - Plans for a Permanent Manned Space Station (Paperback)
Brian O'Leary
R469 Discovery Miles 4 690 Ships in 18 - 22 working days

It's happening now-plans are being formulated under the coordination of NASA to launch a permanent, manned space station by the year 1990. Studies surveying user requirements, system attributes, and architectural options have been conducted, and you're on the top of these far-reaching considerations on the next big step taken within space! Now that the Shuttle and Spacelab are realities, NASA has set sights on a new horizon-a permanent, manned space station in the high frontier. The precedents have been set-Skylab hosted human visits for up to 84 days, and the Soviet's Salyut was and is a temporary base for cosmonaut crew. The differences are the term and scope of space station living and the accomplishments that can be realized with a permanent site and continuous experimentation within its facilities. Brian O'Leary, writer, astrophysicist, and former astronaut, describes the "tinkermodules" that will be carried to the earth's orbit to be assembled as a space station. His inside track information also lay

R500 Discovery Miles 5 000 Ships in 18 - 22 working days

Mass human migrations into outer space may begin this century! Are Earth's inhabitants prepared for this next giant leap? Millions of tax dollars are being employed in NASA and Defense Department research facilities to answer this urgent question. Can humankind migrate to space intelligently, in a civilized manner without real Star Wars? Are these justifiable economic, political, and philosophical reasons for undertaking such a vast project? What legal and institutional implications will surface in distinguishing Earthkind from Spacekind? The immediate and long-range effects of space migration-on earth and its inhabitants, on the solar system and its pioneers-are brought into sharp focus here, within the perspective of the heated debates now taking place in the highest government, scientific, business, and academic circles. From the development of the space shuttle Enterprise and the uses and objectives of the Space Transportation System to the U.S. and Soviet space arsenals of hunter-killer satellites and
