Cooking Cosmos is an exciting book that traces the history of men's endeavor to understand the Universe, and answers the eternal questions: 'Who made this World?' 'Where did it come from?' 'How and why did it begin?' Thousands of years of continual interaction with nature has brought mankind to the present stage when we have some inkling about the working of nature. We now know that the Earth, our habitat, is only one of the planets orbiting the Sun. The Sun itself is a star among billions of stars in the Universe. We know that our solar system came into existence some 4.5 billion years ago and it is but only a tiny component of our galaxy, the Milky Way. Our Universe contains some 100 billion of galaxies. We know that the Universe itself came into existence with the Big Bang some 13.7 billion years ago and even now galaxies are receding from each other with ever increasing speed.This book takes you through the intellectual journey of mankind, unraveling the mysteries of the Cosmos. Starting from Aristotle's Earth-centered Universe, it will take you step by step to the Copernican Sun-centered Universe, to Hubble's expanding Universe, to the Big Bang, to the currently accepted accelerating Universe. In the process, the book explores the origin of space-time, black hole, black hole radiation, dark matter, dark energy, quantum gravity, string theory, all in terms comprehensible to general audiences.
This book follows the historical trail by which humanity has determined the shape and internal structure of the Earth. It is a story that bears on aspects of the history of science, the history of philosophy and the history of mathematics. At the heart of the narrative is the important philosophical practice of performing thought experiments — that is, the art of considering an idealized experiment in the mind. This powerful technique has been used by all the great historical practitioners of science and mathematics, and this book looks specifically at the long history of considering what would happen if an object could be dropped into a tunnel that cuts all the way through the Earth's interior. Indeed, the story begins with a historical whodunit, tracing back through the historical literature the origins of what is now a classic, textbook problem in simple harmonic motion.
This is Clara Bennett’s second book, following “Roswell Revealed: The Untold Story Of America’s Most Famous UFO Incident.” This book delves into humanity's long-standing quest to understand the cosmos, tracing this journey from ancient civilizations to modern scientific endeavors. It highlights how early societies like the Mesopotamians, Egyptians, Babylonians, Greeks, and Romans developed intricate mythologies and astronomical systems to interpret the stars and celestial phenomena. The narrative emphasizes the evolution of astronomical exploration, showing how ancient stargazing laid the foundation for contemporary astronomy. This historical perspective underscores humanity's enduring curiosity and the continuous quest for knowledge about the universe. The book also discusses the role of media and popular culture in shaping public perceptions of extraterrestrial phenomena, particularly UFO sightings. It warns against jumping to conclusions without proper investigation, as sensationalism can lead to myths and exaggerations. The “Goldilocks Zone” concept is introduced, which refers to the habitable zone around stars where life could exist. This idea expands our understanding of the conditions necessary for life beyond Earth and encourages the exploration of diverse environments where life might thrive. The book touches on the Fermi Paradox, which highlights the contradiction between the high probability of extraterrestrial civilizations and the lack of evidence for their existence. This paradox fuels debates about the nature of advanced civilizations and the challenges in making contact with them. The pursuit of technosignatures, or markers of advanced extraterrestrial intelligence, is presented as a key aspect of humanity's insatiable curiosity and quest for knowledge. This search represents a significant frontier in our exploration of the cosmos. The conclusion of Clara Bennet’s book reflects on the transformative journey of interstellar travel, emphasizing humanity's relentless pursuit of discovery and the potential for technological innovation to open new frontiers in space exploration. Overall, the book weaves a narrative that celebrates human curiosity and the relentless drive to unravel the mysteries of the universe, from ancient stargazing to the search for extraterrestrial life and beyond.
Humanity's ongoing quest to unlock the secrets of dark matter and dark energy Heart of Darkness describes the incredible saga of humankind's quest to unravel the deepest secrets of the universe. Over the past forty years, scientists have learned that two little-understood components—dark matter and dark energy—comprise most of the known cosmos, explain the growth of all cosmic structure, and hold the key to the universe's fate. The story of how evidence for the so-called "Lambda-Cold Dark Matter" model of cosmology has been gathered by generations of scientists throughout the world is told here by one of the pioneers of the field, Jeremiah Ostriker, and his coauthor Simon Mitton. From humankind's early attempts to comprehend Earth's place in the solar system, to astronomers' exploration of the Milky Way galaxy and the realm of the nebulae beyond, to the detection of the primordial fluctuations of energy from which all subsequent structure developed, this book explains the physics and the history of how the current model of our universe arose and has passed every test hurled at it by the skeptics. Throughout this rich story, an essential theme is emphasized: how three aspects of rational inquiry—the application of direct measurement and observation, the introduction of mathematical modeling, and the requirement that hypotheses should be testable and verifiable—guide scientific progress and underpin our modern cosmological paradigm. This monumental puzzle is far from complete, however, as scientists confront the mysteries of the ultimate causes of cosmic structure formation and the real nature and origin of dark matter and dark energy.

From the flat earth to the sun's chariot - traditional spiritual texts seem wedded to outmoded cosmologies that show, at best, the scientific limitations of their authors. The Bhagavata Purana, one of the classical scriptures of Hinduism, seems, at first glance, to be no exception. However, a closer examination of this text reveals unexpected depths of knowledge in ancient cosmology. Mysteries of the Sacred Universe shows that the cosmology of the Bhagavata Purana is a sophisticated system, with multiple levels of meaning that encode at least four different astronomical, geographical, and spiritual world models. By viewing the text in the light of modern astronomy, Richard Thompson shows how ancient scientists expressed exact knowledge in apparently mythological terms. Comparison with the ancient traditions of Egypt and the Near East shows early cultural connections between India and these regions - including a surprisingly advanced science. However, quantitative science is only part of the picture. Mysteries of the Sacred Universe also offers a clear understanding of how the spiritual dimension was integrated into ancient Indian cosmology.
The MATT ARCHER SERIES Omnibus includes Matt Archer: Monster Hunter (MA1), Matt Archer: Monster Summer (Novella, MA1.5), Matt Archer: Blade's Edge (MA2), and Matt Archer: Legend (MA3), along with exclusive, brand new short stories, and interviews with the author and characters. About the MATT ARCHER series: Monster Hunter (Matt Archer #1) Fourteen-year-old Matt Archer spends his days studying Algebra, hanging out with his best friend and crushing on the Goddess of Greenhill High, Ella Mitchell. To be honest, he thinks his life is pretty lame until he discovers something terrifying on a weekend camping trip at the local state park. Monsters are real. And living in his backyard. But that's not the half of it. After Matt is forced to kill a strange creature to save his uncle, he finds out that the weird knife he took from his uncle's bag has a secret, one that will change Matt's life. The knife was designed with one purpose: to hunt monsters. And it's chosen Matt as its wielder. Now Matt's part of a world he didn't know existed, working with a covert military unit dedicated to eliminating walking nightmares. Faced with a prophecy about a looming dark war, Matt soon realizes his upcoming Algebra test is the least of his worries. His new double life leaves Matt wondering which is tougher: hunting monsters or asking Ella Mitchell for a date? Blade’s Edge (Matt Archer #2) When Matt Archer was fourteen, he discovered monsters are real. As if that wasn’t enough to go on for a few decades, Matt also found out that he’d been chosen to hunt those monsters--with a sentient, supernatural knife. Now fifteen, Matt has spent the last year working with a clandestine military unit, trying to rid the world of monsters, demons and other vicious creatures, all while keeping it a secret from nearly everyone he knows back home in Billings. Including his mom. Add in a new girlfriend, family secrets, sibling drama and enough homework to sink an aircraft carrier, and Matt’s life has become more complicated than he ever imagined. Worse, the knife-spirit has developed some very definite opinions about Matt’s personal life and it interferes in his business whenever it wants. More and more, Matt’s coming to realize that sharing brain-space with a spirit kind of sucks. When stories of decimated towns and hordes of zombies start pouring into the Pentagon from Afghanistan, Matt knows he’ll be called up soon. Between the new mission and the knife’s increasing control over his mind, Matt wonders if he’ll survive long enough to take his driver’s exam. Legend (Matt Archer #3) When Matt Archer was fourteen, he was chosen—by a magic, spirit-inhabited knife—to hunt monsters with a special paranormal division of the Army. When he was fifteen, he was thrown into a global war the rest of the world didn’t know existed. Now Matt’s sixteen and the war has cost him more than he ever thought it would. He’s also learned that the knife-spirits have an agenda he doesn’t totally agree with. The only problem? The spirits have the upper hand, and they plan to control the fight—and Matt. Then things get worse: the next lunar eclipse cycle is starting, a prominent physicist has gone missing, and Matt’s best friend is thinking about quitting the team. If he loses Will—after everyone else he’s lost—Matt’s not sure how he’ll fight alone. As the source of his nightmares starts to creep out of the shadows, Matt knows he’ll need all the help he can get…because being alone could prove deadly.
​The universe contains many unusual sights and sounds, most of which are either very difficult to witness or simply go unnoticed. With the right tools, time, and location, some of the often talked about but seldom seen and heard gems in our skies can finally be observed. This book introduces readers to the rare and ephemeral happenings above our heads. It offers a crash course in astronomical history, detailing the observations, assumptions, and inventions of different cultures over time as they turned their studies to the stars. Using this as a baseline to redefine truly "rare" occurrences, Jonathan Powell then provides modern-day astronomers at all levels with pointers for what they can witness and when. From phenomena as old and far-off as a supernova witnessed a thousand years ago, and as recent and nearby as Sputnik's famous beeping, this book covers everything that one must know to see, hear, and appreciate the astronomical events happening around us.
