Before the Big Bang, there was a tiny fraction of a second during which a process called inflation expanded a seed much smaller than the nucleus of an atom into a fireball the size of a basketball -- the Big Bang itself. From this fireball, the Universe as we know it developed. The origin of the seed from which the Universe began is not known with certainty, but as John Gribbin explains the most likely explanation is that it was a fluctuation of quantum energy in an eternal sea of cosmic energy. And that means that other seeds must surely have inflated to become other universes, bubbles in the cosmic sea. It is even possible that a collision between our universe and another bubble on the sea of eternity may have left an imprint on the cosmic background radiation, the echo of the Big Bang itself. John Gribbin is an award winning science writer best known for his book In Search of Schrodinger's Cat. He studied astrophysics under Fred Hoyle in Cambridge, and is now a Visiting Fellow in Astronomy at the University of Sussex.

    My experiences, observations, and/or studies have led me to believe the following:* Racism has done more to promote non-justice than any other socio-material system known to have been produced or supported by the people of the known universe.* No major problem that exists between the people of the known universe can be eliminated, until Racism is eliminate

    It is well balanced between theory and practice and covers topics from binary numbers and logic gates to K-maps, variable mapping, counter design etc. Each chapter includes several worked out examples to give studentsa thorough grouding in related design concepts

    These unabridged essays by Carl Sagan were originally published in either popular science magazines or academic journals. This is the first time his essays have become available on audio.

    To understand the universe in the far future, we must first describe its present state and structure on the grand scale, and how its present properties arose. Dr Islam explains these topics in an accessible way in the first part of the book. From this background he speculates about the future evolution of the universe and predicts the major changes that will occur. The author has largely avoided mathematical formalism and therefore the book is well suited to general readers with a modest background knowledge of physics and astronomy.

    He followed his head over his gut and Karina was left permanently paralysed, altering both patient and surgeon's lives for ever.

Comprehensive yet brief, First Along the River discusses the religious and philosophical beliefs that shaped Americans' relationship to the environment, traces the origins and development of government regulations that impact Americans' use of natural resources, and shows why popular environmental groups were founded and how they changed over time.

    Twenty years on, Hancock returns with the sequel to his seminal work filled with completely new, scientific and archaeological evidence, which has only recently come to light...Near the end of the last Ice Age 12,800 years ago, a giant comet that had entered the solar system from deep space thousands of years earlier, broke into multiple fragments. Some of these struck the Earth causing a global cataclysm on a scale unseen since the extinction of the dinosaurs. At least eight of the fragments hit the North American ice cap, while further fragments hit the northern European ice cap. The impacts, from comet fragments a mile wide approaching at more than 60,000 miles an hour, generated huge amounts of heat which instantly liquidized millions of square kilometers of ice, destabilizing the Earth's crust and causing the global Deluge that is remembered in myths all around the world. A second series of impacts, equally devastating, causing further cataclysmic flooding, occurred 11,600 years ago, the exact date that Plato gives for the destruction and submergence of Atlantis.The evidence revealed in this book shows beyond reasonable doubt that an advanced civilization that flourished during the Ice Age was destroyed in the global cataclysms between 12,800 and 11,600 years ago. But there were survivors - known to later cultures by names such as 'the Sages', 'the Magicians', 'the Shining Ones', and 'the Mystery Teachers of Heaven'. They travelled the world in their great ships doing all in their power to keep the spark of civilization burning. They settled at key locations - Gobekli Tepe in Turkey, Baalbek in the Lebanon, Giza in Egypt, ancient Sumer, Mexico, Peru and across the Pacific where a huge pyramid has recently been discovered in Indonesia. Everywhere they went these 'Magicians of the Gods' brought with them the memory of a time when mankind had fallen out of harmony with the universe and paid a heavy price. A memory and a warning to the future...For the comet that wrought such destruction between 12,800 and 11,600 years may not be done with us yet. Astronomers believe that a 20-mile wide 'dark' fragment of the original giant comet remains hidden within its debris stream and threatens the Earth. An astronomical message encoded at Gobekli Tepe, and in the Sphinx and the pyramids of Egypt,warns that the 'Great Return' will occur in our time...

    Every technology we rely on today was created by the human mind, seeking to understand the universe around us. Scientific knowledge is our most precious possession, and our future will be shaped by the breakthroughs to come. In this personal and fascinating work, Neil Turok, Director of the Perimeter Institute for Theoretical Physics, explores the transformative scientific discoveries of the past three centuries -- from classical mechanics, to the nature of light, to the bizarre world of the quantum, and the evolution of the cosmos. Each new discovery has, over time, yielded new technologies causing paradigm shifts in the organization of society. Now, he argues, we are on the cusp of another major transformation: the coming quantum revolution that will supplant our current, dissatisfying digital age. Facing this brave new world, Turok calls for creatively re-inventing the way advanced knowledge is developed and shared, and opening access to the vast, untapped pools of intellectual talent in the developing world. Scientific research, training, and outreach are vital to our future economy, as well as powerful forces for peaceful global progress.

    With case studies and advice for a fitter life, this is an intriguing and thought-provoking book, one which should be read by anyone who cares about their wellbeing.

    With the Big Bang, it went from a state of unimaginable density to an all-encompassing cosmic fireball to a simmering fluid of matter and energy, laying down the seeds for everything from dark matter to black holes to one rocky planet orbiting a star near the edge of a spiral galaxy that happened to develop life. But what happens at the end of the story? In billions of years, humanity could still exist in some unrecognizable form, venturing out to distant space, finding new homes and building new civilizations. But the death of the universe is final. What might such a cataclysm look like? And what does it mean for us? Dr. Katie Mack has been contemplating these questions since she was eighteen, when her astronomy professor first informed her the universe could end at any moment, setting her on the path toward theoretical astrophysics. Now, with lively wit and humor, she unpacks them in The End of Everything, taking us on a mind-bending tour through each of the cosmos’ possible finales: the Big Crunch; the Heat Death; Vacuum Decay; the Big Rip; and the Bounce. In the tradition of Neil DeGrasse’s bestseller Astrophysics for People in a Hurry, Mack guides us through major concepts in quantum mechanics, cosmology, string theory, and much more, in a wildly fun, surprisingly upbeat ride to the farthest reaches of everything we know.

    In presenting their clear and complete explanations, the authors cite both modern data as well as timeless sources of knowledge about the afterlife such as Srimad-Bhagavatam and the Bhagavad-gita.

    It tells the story of two parents from different cultural, linguistic, and ethnic-racial backgrounds who joined to raise their two children with their heritage languages outside their native countries. It also tells the children's story and the way they negotiated three cultures and languages and developed a trilingual identity. It sheds light on how parental support contributed to the children's simultaneous acquisition of three languages in an environment where the main input of the two heritage languages came respectively from the father and from the mother. It addresses the challenges and the unique language developmental characteristics of the two children during their trilingual acquisition process.
