Jonathan I. Katz
R765 Discovery Miles 7 650 Ships in 10 - 15 working days

For over a quarter of a century, gamma-ray bursts were the outstanding mystery in astronomy. No one knew where they were or how they worked. The Biggest Bangs tells how the mystery was unraveled, from the discovery of gamma-ray bursts by a Cold War satellite system monitoring the Nuclear Test Ban Treaty to the localization of bursts in distant galaxies and the observation of surprisingly bright flashes of light from the bursts themselves. The Biggest Bangs is for laymen with an interest in science, physicists and astronomers interested in subjects in those fields not their specialty, students in non-technical astonomy courses, and as supplemental reading for courses in the history of science.

Mike Mullane 1
R470 R443 Discovery Miles 4 430 Save R27 (6%) Ships in 18 - 22 working days

Selected as a Mission Specialist in 1978 in the first group of shuttle astronauts, Mike Mullane completed three missions and logged 356 hours aboard the Discovery and Atlantis shuttles. It was a dream come true. As a boy, Mullane could only read about space travel in science fiction, but the launch of Sputnik changed all that. Space flight became a possible dream and Mike Mullane set out to make it come true. In this absorbing memoir, Mullane gives the first-ever look into the often hilarious, sometime volatile dynamics of space shuttle astronauts - a class that included Vietnam War veterans, feminists, and propeller-headed scientists. With unprecedented candour, Mullane describes the chilling fear and unparalleled joy of space flight. As his career centred around the Challenger disaster, Mullane also recounts the heartache of burying his friends and colleagues. And he pulls no punches as he reveals the ins and outs of NASA, frank in his criticisms of the agency. A blast from start to finish, Riding Rockets is a straight-from-the-gut account of what it means to be an astronaut, just in time for this latest generation of stargazers.

The three greatest scientific mysteries, which remain poorly understood, are the origin of the universe, the origin of life and the development of consciousness. This book describes the processes preceding the Big Bang, the creation of matter, the concentration of that matter into stars and planets, the development of simple life forms and the theory of evolution that has given higher life forms, including mankind.There are many popular and excellent science books that present various aspects of science. However, this book follows a narrow scientific pathway from the Big Bang to mankind, and depicts the causal relationship between each step and the next. The science covered will be enough to satisfy most readers. Many important areas of science are dealt with, and these include cosmology, particle physics, atomic physics, galaxy and star formation, planet formation and aspects of evolution. The necessary science is described in a narrative form that general-interest readers should understand, without the use of equations or formulae.This 2nd edition includes several updates on the subjects that form the pillars of this book. They are: cosmology and astronomy, the features and formation of the solar system, the origin of life, and genetics and evolution. This book will appeal to readers with an interest in biology and those curious about the origins of the universe.

R584 Discovery Miles 5 840 Ships in 10 - 15 working days

In 2004 a rock star, a TV astronomer and a young research astronomer sat down to write the story of the Universe in the order in which it happened, from its birth at the Big Bang 13.7 billion years ago, through to its ultimate demise in the infinitely far future. The aim of this book is to explain the Big Bang and everything that followed in a way that made sense, in the strict order in which events occurred, and without using maths, so it would be understandable to everyone, regardless of educational background. The original edition of Bang! was a bestseller, and a go-to for anyone wanting to understand the story of the origins and evolution of our Universe that did not duck the science. Since the first edition, thousands of planets have been discovered, the 'habitable zone' has expanded and a flotilla of new satellites has explored our own solar system, bringing back fresh images and new science. In this book all the latest findings about the evolution of stars and galaxies are included, and the current thinking about our ultimate origins. The latest ideas about Dark Matter and Dark Energy are explained, all illustrated with new images from the world's largest telescopes and space missions. This is the new, updated, popular guide to 'Life, the Universe, and Everything' - The Complete History of the Universe.

This book presents in a simple style the success story of modern astrophysics - how the application of known physics to models of stars can, together with the observational data, help us understand what stars are made of, how they live and how they die. The account is non-technical but scientifically accurate. It is interspersed with anecdotes and analogies to make the subject matter readable and understandable even to a lay reader with some basic scientific background.

Centauri Dreams - Imagining and Planning Interstellar Exploration (Hardcover, 2004 ed.): Paul Gilster Centauri Dreams - Imagining and Planning Interstellar Exploration (Hardcover, 2004 ed.)
Paul Gilster
R1,258 R1,087 Discovery Miles 10 870 Save R171 (14%) Ships in 18 - 22 working days

Why, today, would anyone undertake a plan to launch a spacecraft some 30 years in the future, and on a journey that would take some 40 years to complete? Paul Gilster investigates the science, and the spirit, of the NASA and JPL researchers who are actually at work on just such a project.

From the reviews:

"Gilster introduces the challenges of imagining and planning interstellar exploration by leading readers through the difficulties of reaching and exploring the nearest bright star, Alpha Centauri. Seeded by ideas and concepts of the late Robert Forward, the narrative is framed as a learning process undertaken simultaneously by writer and reader. Although Alpha Centauri is astronomically nearby, a postulated trip by robot spacecraft, followed by manned exploration, would take 50 to 1,000 years, depending on the type of spacecraft propulsion used. Various methods for interstellar travel are introduced and discussed, including solar sails that use the power of starlight, nuclear fusion, antimatter hybrid systems, and beamed laser propulsion. One challenge is to get there in a reasonable time so that funding support, public interest, and events on Earth will not divert attention from the mission. Another challenge is timing the mission relative to available technology, because with better technology it might be possible to send a later robot on the same mission in less time. The book has no figures, tables, or illustrations but does include 30 pages of notes and an adequate 14-page index. Though the concepts presented are often fanciful, this book will appeal to readers who wonder about the future of exploration beyond the solar system. Summing Up: Highly recommended. Generalreaders; professionals." (W. E. Howard III, CHOICE, March 2005)

Witnessing a total solar eclipse is a wondrous and unforgettable event! Eclipse Chasers is a guide to past and future Australian total solar eclipses, exploring historical and cultural knowledge, as well as featuring five upcoming eclipses that will be visible in Australia. The science of eclipses is explained, as well as how to prepare for an eclipse and view it safely. For upcoming eclipses the best locations to view each one are revealed, alongside tips for taking photographs. The book also reveals untold stories of how past Australian astronomers observed the total eclipses that have occurred since European settlement, and how these eclipses were celebrated in popular culture, poetry and art. It explores the great significance of solar eclipses for First Nations peoples, and their observations and cultural meanings. Eclipse Chasers showcases the drama and beauty of total solar eclipses and is essential for anyone fascinated by these amazing events. IMPORTANT NEWS: The next total solar eclipse in Australia is set to occur April 20, 2023. The Ningaloo Eclipse will entice people from all over the world to travel to Exmouth in Western Australia to have front row seats. KEY INFO: Includes locations and times to safely view a series of total solar eclipses coming up over the next two decades in Australia: April 2023; July 2028, Nov 2030, July 2037 and December 2038. Interest in eclipses is set to surge in Australia as we will have the opportunity to view five over the next two decades. Worldwide there are usually just one or two total solar eclipses each year, so it is remarkable that so many can be seen in one location so close together. A media campaign will support the release of Eclipse Chasers with expected coverage in major newspapers and national radio. The book includes information for teachers, and teacher notes will be available from the CSIRO Publishing website.

Space was at the center of America's imagination in the 1960s. President John F. Kennedy's visionary statement captured the mood of the day: "We choose to go to the moon in this decade and do the other things, not because they are easy, but because they are hard." The Apollo mission's success in July 1969 made almost anything seem possible, but the Cold War made space flight the province of governmental agencies in the United States. When the Apollo program ended in 1972, space lost its hold on the public interest, as the great achievements wound down. Entrepreneurs are beginning to pick up the slack--looking for safer, more reliable, and more cost effective ways of exploring space. Entrepreneurial activity may make create a renaissance in human spaceflight. The private sector can energize the quest for space exploration and shape the race for the final frontier. Space entrepreneurs and private sector firms are making significant innovations in space travel. They have plans for future tourism in space and safer shuttles. Solomon details current US and international laws dealing with space use, settlement, and exploration, and offers policy recommendations to facilitate privatization. As private enterprise takes hold, it threatens to change the space landscape forever. Individuals are designing spacecraft, start-up companies are testing prototypes, and reservations are being taken for suborbital space flights. With for-profit enterprises carving out a new realm, it is entirely possible that space will one day be a sea of hotels and/or a repository of resources for big business. It is important that regulations are in place for this eventuality. These new developments have great importance, huge implications, and urgency for everyone.

Harvard's top astronomer takes us inside the mind-blowing story of the first interstellar visitor to our solar system.

In late 2017, scientists at a Hawaiian observatory glimpsed a strange object soaring through our inner solar system. Astrophysicist Avi Loeb conclusively showed it was not an asteroid; it was moving too fast along a strange orbit, and leaving no trail of gas or debris in its wake. There was only one conceivable explanation: the object was a piece of advanced technology created by a distant alien civilization.

In Extraterrestrial, Loeb takes readers inside the thrilling story of the first interstellar visitor to be spotted in our solar system. He outlines his theory and its profound implications: for science, for religion, and for the future of our planet. A mind-bending journey through the furthest reaches of science, space-time, and the human imagination, Extraterrestrial challenges readers to aim for the stars-and to think critically about what's out there, no matter how strange it seems.

He examines these important works by acknowledged authorities in the field to see how they have stood the test of time. Where the luminaries have failed, he looks for clues that the layman reader could have used to raise doubts about what was being said. The aim of this highly accessible book is to develop tools for the non-scientist to evaluate the strange and marvelous results that astronomers report, in place of the highly-developed scientific and mathematical techniques available to the scientists themselves. A must-read for all science and astronomy enthusiasts.

Ever since its infancy, humankind has been seeking answers to some very basic and profound questions. Did the Universe begin? If it did, how old is it, and where did it come from? What is its shape? What is it made of? Fascinating myths and brilliant in- itions attempting to solve such enigmas can be found all through the history of human thought. Every culture has its own legends, itsownworldcreationtales, itsphilosophicalspeculations, itsre- gious beliefs. Modern science, however, cannot content itself with fanciful explanations, no matter how suggestive they are. No- days, our theories about the Universe, built upon rational ded- tion, have to survive the hard test of experiment and observation. Cosmology, the science which studies the origin and evo- tion of the Universe, had to overcome enormous dif?culties before it could achieve the same level of dignity as other physical dis- plines. At ?rst, it had no serious physical model and mathematical tools that could be used to address the complexity of the problems it had to face. Then, it suffered from a chronic lack of experim- tal data, which made it almost impossible to test the theoretical speculations. Given this situation, answering rigorously the many questions on the nature of the Universe seemed nothing more than a delusion. Today, however, things have changed. We live in the golden age of cosmology: an exciting moment, when, for the ?rst time, we are able to scienti?cally understand our Univers

From the Big Bang to the Gaia Mission, this is a very personal history of the universe through the author's favourite 100 stars. Astronomer Florian Freistetter has chosen 100 stars that have almost nothing in common. Some are bright and famous, some shine so feebly you need a huge telescope. There are big stars, small stars, nearby stars and faraway stars. Some died a while ago, others have not even yet come into being. Collectively they tell the story of the whole world, according to Freistetter. There is Algol, for example, the Demon Star, whose strange behaviour has long caused people sleepless nights. And Gamma Draconis, from which we know that the earth rotates around its own axis. There is also the star sequence 61 Cygni, which revealed the size of the cosmos to us. Then there are certain stars used by astronomers to search for extra-terrestrial life, to explore interstellar space travel, or to explain why the dinosaurs became extinct. In 100 short, fascinating and entertaining chapters, Freistetter not only reveals the past and future of the cosmos, but also the story of the people who have tried to understand the world in which we live.

Escape From Earth - A Secret History of the Space Rocket (Paperback): Fraser MacDonald Escape From Earth - A Secret History of the Space Rocket (Paperback)
Fraser MacDonald 1
R268 Discovery Miles 2 680 Ships in 10 - 15 working days

ESCAPE FROM EARTH is the untold story of the engineers, dreamers and rebels who started the American space programme. In particular, it is the story of Frank Malina, founder of what became Nasa's Jet Propulsion Laboratory and the scientist who cracked the, as he called it, problem of escape from the Earth by rocket.

It's a wild ride. Jack Parsons, Malina's chemistry-expert research partner, was a bed-hopping occultist with delusions of grandeur. We get all the horrible details: drug parties and sex magic, cameos by Aleister Crowley and L Ron Hubbard, and an ill-fated attempt to start a mail-order religion.

Armed with hitherto unpublished letters, journals, and documents from the Malina family archives, Fraser MacDonald reveals what we didn't know. Jack Parsons betrayed Frank Malina to the FBI, cooperating fully in their investigation of Malina for un-American activities. The Jet Propulsion Lab's second director secretly denounced Frank as a Communist. Frank's research group had close ties to the spy network of the infamous Rosenbergs - the only Americans executed during the Red Scare. This is a story of soaring ideals entangled in the most human of complications: infidelity and divorce, betrayal and treason.

This book explains how it came to be that Venus and Earth, while very similar in chemical composition, zonation, size and heliocentric distance from the Sun, are very different in surface environmental conditions. It is argued here that these differences can be accounted for by planetoid capture processes and the subsequent evolution of the planet-satellite system. Venus captured a one-half moon-mass planetoid early in its history in the retrograde direction and underwent its "fatal attraction scenario" with its satellite (Adonis). Earth, on the other hand, captured a moon-mass planetoid (Luna) early in its history in prograde orbit and underwent a benign estrangement scenario with its captured satellite.

NASA's history is a familiar story, one that typically peaks with Neil Armstrong taking his small step on the Moon in 1969. But America's space agency wasn't created in a vacuum. It was assembled from pre-existing parts, drawing together some of the best minds the non-Soviet world had to offer. In the 1930s, rockets were all the rage in Germany, the focus both of scientists hoping to fly into space and of the German armed forces, looking to circumvent the restrictions of the Treaty of Versailles. One of the key figures in this period was Wernher von Braun, an engineer who designed the rockets that became the devastating V-2. As the war came to its chaotic conclusion, von Braun escaped from the ruins of Nazi Germany, and was taken to America where he began developing missiles for the US Army. Meanwhile, the US Air Force was looking ahead to a time when men would fly in space, and test pilots like Neil Armstrong were flying cutting-edge, rocket-powered aircraft in the thin upper atmosphere. Breaking the Chains of Gravity tells the story of America's nascent space program, its scientific advances, its personalities and the rivalries it caused between the various arms of the US military. At this point getting a man in space became a national imperative, leading to the creation of the National Aeronautics and Space Administration, otherwise known as NASA.

What is Mars? From the ancients to the present, we have imagined Mars repeatedly and studied it longingly. As scientific knowledge of Mars has changed, so has the cultural imagination of this celestial neighbors. The earth-centered beginnings of astronomy connected the blood-red planet with the God of War. The Copernican Revolution and a later, simple mistranslation from Italian supported fantastic visions of distant Mars as the abode of life variously bizarre, ideal, or malignant. In the work of H. G. Wells and Orson Welles, in books, films, radio, and television, Mars reflected not only eternal hopes and fears but then-current political realities. In recent years, "NASA-fication" has brought Mars home, imagining the Red Planet almost as an eighth continent of Earth, a candidate for exploration and exploitation both in fiction and in fact. Rabkin weaves a chronological tale of many threads, including mythology, astrology, astronomy, literary criticism, and cultural studies. More than 60 brief chapters focus on people, events, or phenomena concerning the eternal object of curiosity, Mars. This rich series of readable, illustrated chapters can be sampled at will for the fun of discovery, read sequentially as a connected history, or enjoyed as a resource for the contemplation. Featuring over 100 illustrations, this unique examination of humanity's most storied companion serves as a resource for the study of ourselves.
