Isaac Asimov concludes that we are not alone! Using the most up-to-date astronomical research as the backdrop for speculation, Asimov confronts the possibilities of other-worldly life head-on in Extraterrestrial Civilizations . In what will surely become one of the most provocative books ever written on the possibilities of life elsewhere in the universe, the incomparable Isaac Asimov provides chilling, hopeful, and exciting new insights. Here is astounding speculation about where the next giant step for mankind will take us. . . . Praise for Extraterrestrial Civilizations "[Isaac] Asimov holds our attention as he builds a meticulous case. We are not alone. It's just a matter of time until we know for sure." -- Miami Herald "Intriguing" -- Publishers Weekly

The subtitle of this volume is exact, for Leo Szilard's work ranged from physics to biology; he crossed over with ease from the world of neutrons to that of neurons, from the nuclei of atoms to the nuclei of cells. At a deeper level, all of these research activities converge, unified as they are by Szilard's interest in the fundamental ideas of order and organization that underlie them all. It is no accident, as Jacques Monod notes in this foreword, that this interest should appear explicitly as the subject of one of his very first papers, and of his last. In the former, concerning the operations of an intelligent being on a thermodynamic system, Szilard anticipated by many years the entropic formulation of information theory, while the latter, "On Memory and Recall," is concerned with the organization of the central nervous system. Szilard's spontaneous, unrepressed flow of ideas was followed by a critical process of selection and refinement, which may account for the relatively small number of published papers—under thirty—found in this collection. The papers are arranged chronologically, and their ordering comprises a resume of Szilard's scientific life. The first group of papers, 1925-1939, all deal with various aspects of physics—thermodynamics, x-ray crystallography, and nuclear physics. The work in this last area includes studies of neutron bombardment and of the possibilities of nuclear fission and chain reactions, which Szilard was among the first to envision. The second group, 1940-1945, comprises the first publication of documents relating to the Manhattan Project, and reflect Szilard's part in it. Most of these documents were previously classified. There are no scientific papers from the years 1946-1948. These were years when Szilard was intensely active in the political and social arena, attempting to bring the atomic bomb under international control. Documents relating to this struggle, and to his earlier leadership in efforts both to undertake the atomic project and to prevent the bomb's use without warning against Japan, will be collected in another volume. It was also during these critical years that Szilard's interest decisively turned from physics to biology. The third group covers the years 1949-1964, when Szilard's interest centered around biological problems. Among these are the regulation of cellular metabolism, antibody formation, the aging process, and the functioning of the central nervous system. A final section of the book reproduces patents and patent applications of historic importance dating from 1923 to 1959, and ranging from the invention of a refrigerator, jointly with Albert Einstein; an application anticipating the cyclotron in 1928; and the general concepts of a nuclear chain reaction in 1934 to the first patent on the nuclear reactor granted jointly to Fermi and Szilard.

Gold, gold, gold for Australia's mega-selling scientist's 27th book... 'Nullius in verba', the Royal Society's motto, roughly translated, means 'take nobody's word for it'. Why not do the experiment for yourself and see the reality of nature. Don't trust authority - trust nature.Does cranberry juice cure urinary tract infections? Is the hookah really a safer way to smoke? Will the Large Hadron Collider destroy the Earth and the Universe? Is the purpose of the peacock's tail to attract females? And in the unlikely event of a plane crash, are some seats safer than others?the human hand has 27 bones; Uranus has 27 moons; 27 is a perfect cube, being 3 x 3 x 3; and in this, Dr Karl's 27th book, he takes us on another exploration of the dazzling world of science.

In the next book in Dr Karl's mega-selling science series, Australia's favourite scientist answers more curly questions about life, the universe and everything; questions such as Are virgin births possible? (they are) Will a black hole suck you in? (it won't) Is the most radioactive device in our homes the microwave? (it's not, it's the smoke detector)No-one conveys the excitement and wonder of science quite like Dr Karl and this, his twenty-fifth book, takes us on another thoroughly entertaining exploration of the world around us. If you like your science fun and unpredictable, don't miss this new addition to the Dr Karl library.

In this, his 45th book, Dr Karl goes full kolour, with brilliant and funny illustrations to match his dress sense. So take a technikolour trip through science with the intrepid Dr Karl, Australia's favourite science guru. Q: HOW MANY DR KARL BOOKS ARE THERE IN THE UNIVERSE? A: MORE THAN A MILLION! Dr Karl is on a mission to track down Awe and Wonder in the Universe. Why do wombats poo cubes? What nearly destroyed humanity on Halloween 2015? How do you use an incinerating toilet? Find out why we've sent a spacecraft with Dr Karl's name on it to kiss the Sun, whether cannibalism is nutritious, and the answer to the Biggeset Question of All - why does spaghetti always break into three pieces? Plus a whole lot more. So strap in and get ready for a random ride through the Universe. Who knows where you'll end up!

A fascinating tribute to the forefathers of two of today’s most exciting scientific fields Thanks to Max Delbruck and George Gamow, today we have mapped the human genome and understand the ramifications of the Big Bang. In his characteristically inviting and elegant style, Gino Segre brings to life the story of these two great scientists and their long friendship and offers an accessible inside look the people behind the scenes of science—the collaboration and competition, the quirks and failures, the role of intuition and luck, and the sense of wonder and curiosity that keeps these extraordinary minds going.
