For all curious readers, a lively introduction to radical ideas and discoveries that are transforming our knowledge of the universe This book provides a tour of the "greatest hits" of cosmological discoveries-the ideas that reshaped our universe over the past century. The cosmos, once understood as a stagnant place, filled with the ordinary, is now a universe that is expanding at an accelerating pace, propelled by dark energy and structured by dark matter. Priyamvada Natarajan, our guide to these ideas, is someone at the forefront of the research-an astrophysicist who literally creates maps of invisible matter in the universe. She not only explains for a wide audience the science behind these essential ideas but also provides an understanding of how radical scientific theories gain acceptance. The formation and growth of black holes, dark matter halos, the accelerating expansion of the universe, the echo of the big bang, the discovery of exoplanets, and the possibility of other universes-these are some of the puzzling cosmological topics of the early twenty-first century. Natarajan discusses why the acceptance of new ideas about the universe and our place in it has never been linear and always contested even within the scientific community. And she affirms that, shifting and incomplete as science always must be, it offers the best path we have toward making sense of our wondrous, mysterious universe. Format:Hardback

This item is sold brand new. It is ordered on demand from our supplier and is usually dispatched within 4 - 9 working days Everything around us is made of 'stuff', from planets, to books, to our own bodies. Whatever it is, we call it matter or material substance. It is solid; it has mass. But what is matter, exactly? We are taught in school that matter is not continuous, but discrete. As a few of the philosophers of ancient Greece once speculated, nearly two and a half thousand years ago, matter comes in 'lumps', and science has relentlessly peeled away successive layers of matter to reveal its ultimate constituents. Surely, we can't keep doing this indefinitely. We imagine that we should eventually run up against some kind of ultimately fundamental, indivisible type of stuff, the building blocks from which everything in the Universe is made. The English physicist Paul Dirac called this 'the dream of philosophers'. But science has discovered that the foundations of our Universe are not as solid or as certain and dependable as we might have once imagined. They are instead built from ghosts and phantoms, of a peculiar quantum kind. And, at some point on this exciting journey of scientific discovery, we lost our grip on the reassuringly familiar concept of mass. How did this happen? How did the answers to our questions become so complicated and so difficult to comprehend? In Mass Jim Baggott explains how we come to find ourselves here, confronted by a very different understanding of the nature of matter, the origin of mass, and its implications for our understanding of the material world. Ranging from the Greek philosophers Leucippus and Democritus, and their theories of atoms and void, to the development of quantum field theory and the discovery of a Higgs boson-like particle, he explores our changing understanding of the nature of matter, and the fundamental related concept of mass. Features Summary Jim Baggott explores how our understanding of the nature of matter, and its fundamental property of mass, has developed, from the ancient Greek view of indivisible atoms to quantum mechanics...

It is ordered on demand from our supplier and is usually dispatched within 7 - 11 working days 'We ourselves were almost awestruck, not so much at the power of the Bomb, for this we had expected, but because the Americans had used it with so little notice.' R. V. Jones, head of wartime British Scientific Intelligence Marcial Echenique, a Cambridge professor, recently became curious when he found wiring concealed under the floorboards of his country mansion, Farm Hall. The manor had an astonishing past as an MI6 staging post for some of the most secret operations of the Second World War. But in April 1945, Farm Hall was to play an even more astounding role, housing ten of Germany's top nuclear physicists captured in daring raids. Amid the chaos of the disintegrating Third Reich they were flown to England covertly in a mission code-named Operation Big. Every word they uttered was bugged by MI6 eavesdroppers using the wires found by the professor. After the dropping of the atom bombs on Japan, these men would claim they could have developed A-bombs for the Third Reich, but did not 'for the greater good of mankind'. Most believe this to have been a lie. But was there an even greater deception? Were they captured not to stop Hitler, but to stop Stalin? Did the US drop the Bomb as a show of power not to the Japanese, but to the Soviets? Colin Brown guides us through a world of espionage, scientific discovery and questions of morality as he reveals the extraordinary truth surrounding Hitler's atomic bomb.

This item did belong to a library before but book and wrapper remained in a very good condition.  >>>  In the culture of the galaxy, the Star-Pilots of the starships that link the cosmos together have become the great heroes of the day. Grainger, who has become a legend in his own lifetime, is drafted to fly the prototype (the Hooded Swan) of a new ship that could revolutionize space travel. The members of the ultra-ascetic Church of the Exclusive Reward have colonized a number of marginal worlds to exclude themselves from galactic society. On Rhapsody, church members lead a completely subterranean existence. Even closed societies have their rebels, however, so when a major scientific discovery emerges from the caves of the dark planet, everything there falls apart. If Grainger can secure a share in the coming bonanza, he could buy back his freedom from Titus Charlot. Before he can do that, however, he has to find some way of just staying alive....  *N.B.*   If you buy more than one book from me you only pay R 6 postage on each additional book - See what else I have to offer, it might just be worth your while.

It is ordered on demand from our supplier and is usually dispatched within 7 - 11 working days Jo Dunkley combines her expertise as an astrophysicist with her talents as a teacher and writer in this lively and exceptionally clear introduction to the structure and history of the universe and its enduring mysteries. Most of us have heard of black holes and supernovas, galaxies and the Big Bang. But few of us understand more than the bare facts about the universe we call home. What is really out there? How did it all begin? Where are we going? Jo Dunkley begins in Earth's neighborhood, explaining the nature of the Solar System, the stars in our night sky, and the Milky Way. She then moves out past nearby galaxies-and back in time-to the horizon of the observable universe, which contains over a hundred billion galaxies, each with billions of stars, many orbited by planets, some of which may host life. These visible objects in space sit in a web of dark matter, mysterious stuff we cannot see or yet understand. Dunkley traces the evolution of the universe from the Big Bang fourteen billion years ago, past the birth of the Sun and our planets, to today and beyond. She explains cutting-edge debates about such perplexing phenomena as the accelerating expansion of the universe and the possibility that our universe is only one of many. Our Universe conveys with authority and grace the thrill of scientific discovery and a contagious enthusiasm for the endless wonders of space-time.

In Brief Candle in the Dark he continues his autobiography, following the threads that have run through the second half of his life so far and homing in on the key individuals, institutions and ideas that inspired and motivated him. He paints a vivid picture, coloured with wit, anecdote and digression, of the twenty-five postgraduate years he spent teaching at Oxford. He pays affectionate tribute to past colleagues and students, recalling the idiosyncrasies of an establishment steeped in ancient tradition and arcane ritual while also recording his respect for the profound commitment to learning and discovery that lies at its core. He invites us to share the life of a travelling scientist, from fieldwork on the Panama Canal to conferences of stratospheric eminence in exotic locations in the company of some of the most prominent of the world's scientific luminaries. And he describes his experiences with his many publishers, television producers, interviewers and partners in debate, not least in the heady period when, after publication of The God Delusion in 2006, he is dubbed the world's most outspoken and controversial atheist. Most important of all, for the first time he reviews with fresh and stimulating insights the evolving narrative of his ideas about science over the course of his highly distinguished career as thinker, teacher and writer. In Brief Candle in the Dark we are invited to enter with him a constantly stimulating world of discovery and to meet a fascinating cast of exceptional characters described by the talented pen of one of the most exceptional of them all.

1998 paperback with 507 pages in good condition. R46 postage in SA. Ship of Gold tells the story of the sinking of the SS Central America, a side-wheel steamer carrying nearly six hundred passengers returning from the California Gold Rush, two hundred miles off the Carolina coast in September 1857. Over four hundred lives and twenty-one tons of California gold were lost. It was the worst peacetime disaster at sea in American history, a tragedy that remained lost in legend for over a century. In the 1980s, a young engineer from Ohio set out to do what no one, not even the United States Navy, had been able to do: establish a working presence on the deep-ocean floor and open it to science, archaeology, history, medicine, and recovery. The SS Central America became the target of his project. After years of intensive efforts, Tommy Thompson and the Columbus-America Discovery Group found the SS Central America in eight thousand feet of water, and in October 1989 they sailed into Norfolk with her recovered treasure: gold coins, bars, nuggets, and dust, plus steamer trunks filled with period clothes, newspapers, books, and journals. Gary Kinder tells this extraordinary tale of history, human drama, heroic rescue, scientific ingenuity, and individual courage.

  An Eloquent Picture Gallery: The South African Portrait Photographs of Gustav Theodor Fritsch, 1863-1865 - Keith Hamilton Dietrich, Andrew Bank (2008)   Bringing to life a unique cultural gallery of both known and unknown figures of the early 1860s with an astonishing veracity, this remarkable photographic collection is a visual documentation of South Africas people. Aesthetically stunning and of surprising technical quality for the period taken, this intriguing collage represents the life work of 25-year-old German doctor and anthropologist Gustav Fritsch, who utilized the relatively new photographic medium to complement his scientific expedition to the South African landscape. Reflecting how the native tribes remained untouched by the social and industrial revolution around them, and accompanied by essays that set in context Fritschs outlook on racial discovery and theory, this invaluable photographic insight is an artistic and historically significant addition to South Africas cultural heritage.

Although Singapore may appear to be the most westernized country in Asia, she is nevertheless a multi-cultural Asian society. Having the most open economy in the world, Singapore is plugged into the global marketplace of education and learning. The development of human capital is used as a strategic economic driver to internationalize and transform education for sustainable competitive advantage. Singapore's education system, regarded as one of the consistently best performing in the world, offers a unique opportunity to explore issues where eastern and western culture, values, beliefs, learning and knowledge systems converge, clash, and at times diverge.This book is meant to extend our knowledge on the role of `learning', often overlooked and taken for granted as the air that we breathe but which constantly transforms our lives and reshapes societies. It is the first book that deals with the dichotomy of `east' and `west' going beyond the traditional learning and education framework to other areas such as economic, socio-cultural, political, and technological dimensions that impact Singapore. It puts together key topical issues and explores the underbelly of how a small 'resourceless' independent city-state like Singapore stays ahead of the learning curve, even while facing increasingly intense global competition where the discovery and emergence of new systems for empowerment and independence and the resulting creation of new knowledge and modes of communication are challenging traditional boundaries between the virtual and real world.
