The Origin of Stars
Whre do stars come from and how do they form? These are profound questions which link the nature of our Universe to the roots of mankind. Yet, until a recent revolution in understanding, the proposed answers have been raw speculation. Now, accompanying penetrating observations, a new picture has come into prominence. This book presents the latest astounding observations and scientific ideas covering star formation, star birth and early development. It encompasses all aspects, from the dramatic stories of individual objects, to the collective influence of entire stellar systems. The very first stars to come into existence and the nurturing of planets are discussed to provide the reader with a comprehensive overview. Presenting background information with only the essential mathematics, this book will appeal to scientists wishing to expand their horizons, students seeking solid foundations, and general readers with enquiring minds.
Our Worlds
Our Worlds provides a rare "insider" look into the universe and planetary science during the current golden age of space exploration. Readers are guided on an exciting voyage of discovery by eight distinguished researchers who explore the universe with cutting edge techniques. From Chief Scientist on NASA's New Millennium Program Ellen Stofan to planetary theorist Bill McKinnon, each writes from a personal point of view, sharing to the fullest the science and emotion found in the most enticing discoveries and the wonders of the solar system. This volume gives readers an up-close view of Mars, Venus, and the Moon; a trip with Halley's Comet; a visit to the moons of Io, Titan, and Triton; and ...
Cosmology and Controversy
For over three millennia, most people could understand the universe only in terms of myth, religion, and philosophy. Between 1920 and 1970, cosmology transformed into a branch of physics. With this remarkably rapid change came a theory that would finally lend empirical support to many long-held beliefs about the origins and development of the entire universe: the theory of the big bang. In this book, Helge Kragh presents the development of scientific cosmology for the first time as a historical event, one that embroiled many famous scientists in a controversy over the very notion of an evolving universe with a beginning in time. In rich detail he examines how the big-bang theory drew inspira...
The Comets and Their Origin
This 1953 book sets out some observational facts about comets and then accounts for their origin and explains how comet tails are formed.
Ambassadors from Earth
Rewind to the 1950s and ponder: was America's first satellite really built by a college student? How did a small band of underappreciated Russian engineers get pictures of the moon's far side--using stolen American film? As the 1960s progressed, consider: how the heck did people learn to steer a spacecraft using nothing but gravity? And just how were humans able to goose a spaceship through a thirty-year journey to the literal edge of our solar system? Ambassadors from Earth relates the story of the first unmanned space probes and planetary explorers--from the Sputnik and Explorer satellites launched in the late 1950s to the thrilling interstellar Voyager missions of the '70s--that yielded s...
The Stability of Rotating Liquid Masses
This 1953 book by British astronomer Raymond Arthur Lyttleton presents an account of advances in relation to a classical problem of mathematical astronomy. The text is mainly concerned with those parts of the theory most directly involved in determining the evolution of gravitating liquid masses.
Reinvention Of Science, The: Slaying The Dragons Of Dogma And Ignorance
Throughout the history of science, different thinkers, philosophers and scientists postulated the existence of entities that, in spite of their not being visible or detectable in their time, or perhaps ever, were nevertheless useful to explain the real world. We started this book by looking at a handful of these entities. These included phlogiston to account for fire; the luminiferous ether for propagation of radiation; the homunculus to provide for heredity; and crystalline spheres to carry the wandering planets around the earth. Many of these erroneous beliefs had held up progress, just as dragons drawn on the edges of a map discouraged exploration. This pattern of science evolution contin...
Against the Tide
Nobody should have a monopoly of the truth in this universe. The censorship and suppression of challenging ideas against the tide of mainstream research, the blacklisting of scientists, for instance, is neither the best way to do and filter science, nor to promote progress in the human knowledge. The removal of good and novel ideas from the scientific stage is very detrimental to the pursuit of the truth. There are instances in which a mere unqualified belief can occasionally be converted into a generally accepted scientific theory through the screening action of refereed literature and meetings planned by the scientific organizing committees and through the distribution of funds controlled ...
The Greatest Comets in History
Naked-eye comets are far from uncommon. As a rough average, one appears every 18 months or thereabouts, and it is not very unusual to see more than two in a single year. The record so far seems to have been 2004, with a total of five comets visible without optical aid. But 2006, 1970, and 1911 were not far behind with a total of four apiece. Yet, the majority of these pass unnoticed by the general public. Most simply look like fuzzy stars with tails that are either faint or below the naked-eye threshold. The ‘classical’ comet – a bright star-like object with a long flowing tail – is a sight that graces our skies about once per decade, on average. These ‘great comets’ are surely a...
A Century of Ideas
Shortly after its inauguration in 1985 the Birla Science Centre, Hyderabad, India, started a series of lectures by Nobel Laureates and other scientists of international renown, mostly on Physics and Astronomy. The present collection mostly consists of lectures on frontier topics. The transcript of each lecture is preceded by a short biography of the Nobel Laureate/Scientist in question. The lectures are aimed at a wide non-specialist but higher educated audience.
