    Each 3000-word essay simply and concisely examines a question that has eternally perplexed enquiring minds, providing answers from history's great thinkers. This ambitious project is a unique distillation of humanity's best ideas. In Big Questions: The Universe, Dr Stuart Clark tackles the 20 key questions of astronomy and cosmology: What is the universe? How big is the universe? How old is the universe? What are stars made from? How did the Universe form? Why do the planets stay in orbit? Was Einstein right? What are black holes? How did the Earth form? What were the first celestial objects? What is dark matter? What is dark energy? Are we really made from stardust? Is there life on Mars? Are there other intelligent beings? Can we travel through time and space? Can the laws of physics change? Are there alternative universes? What will be the fate of the universe? Is there cosmological evidence for God? About the Author: Stuart Clark Dr Stuart Clark is author of the critically acclaimed The Sun Kings and a former editor of the UK's best-selling astronomy magazine, Astronomy Now. He currently writes for the European Space Agency and is a regular contributor to magazines such as New Scientist and BBC Focus. Dr Clark's previous books also include Deep Space (Quercus 2007), Galaxy (Quercus 2008), Journey to the Stars and Universe in Focus: The Story of the Hubble Telescope.

    Together, they explain virtually everything about the world we live in. But, almost a century after their advent, most people haven't the slightest clue what either is about. Did you know that there's so much empty space inside matter that the entire human race could be squeezed into the volume of a sugar cube? Or that you grow old more quickly on the top floor of a building than on the ground floor? And did you realise that 1 percent of the static on a TV tuned between stations is a relic of the Big Bang?

    This user-friendly self-study guide is aimed at the general reader who is motivated to tackle that not insignificant challenge. The book is written using straightforward and accessible language, with clear derivations and explanations as well as numerous fully solved problems. For those with minimal mathematical background, the first chapter provides a crash course in foundation mathematics. The reader is then taken gently by the hand and guided through a wide range of fundamental topics, including Newtonian mechanics; the Lorentz transformations; tensor calculus; the Einstein field equations; the Schwarzschild solution (which gives a good approximation of the spacetime of our Solar System); simple black holes and relativistic cosmology. Following the historic 2015 LIGO (Laser Interferometer Gravitational-Wave Observatory) detection, there is now an additional chapter on gravitational waves, ripples in the fabric of spacetime that potentially provide a revolutionary new way to study the universe. Special relativity helps explain a huge range of non-gravitational physical phenomena and has some strangely counter-intuitive consequences. These include time dilation, length contraction, the relativity of simultaneity, mass-energy equivalence and an absolute speed limit. General relativity, the leading theory of gravity, is at the heart of our understanding of cosmology and black holes.Understand even the basics of Einstein's amazing theory and the world will never seem the same again.

      In the past few years, a handful of scientists have been in a race to explain a disturbing aspect of our universe: only 4 percent of it consists of the matter that makes up you, me, our books, and every planet, star, and galaxy. The rest—96 percent of the universe—is completely unknown.   Richard Panek tells the dramatic story of how scientists reached this conclusion, and what they’re doing to find this "dark" matter and an even more bizarre substance called dark energy. Based on in-depth, on-site reporting and hundreds of interviews—with everyone from Berkeley’s feisty Saul Perlmutter and Johns Hopkins’s meticulous Adam Riess to the quietly revolutionary Vera Rubin—the book offers an intimate portrait of the bitter rivalries and fruitful collaborations, the eureka moments and blind alleys, that have fueled their search, redefined science, and reinvented the universe.

    In ten short chapters of lyrical prose—each one an ode to a breathtaking realm of discovery—Stefan Klein uses everyday objects and events as a springboard to meditate on the beauty of the underlying science. Klein sees in a single rose the sublime interdependence of all life; a day of stormy weather points to the world’s unpredictability; a marble conjures the birth of the cosmos. As he contemplates the deepest mysteries—the nature of reality, dark matter, humanity’s place among the galaxies, and more—Klein encourages us to fall in love with the universe the way scientists do: with a grasp of the key ideas and theories of twenty-first-century physics that bring to life the wonders of, really, everything. You won’t look at a rose—or at our world—the same way again.

    This is the story of Albert Einstein who born in Germany in 1879. Despite facing countless difficulties in his life, he earned his name in the field of science and proved that what extent a person can go to chose his way. No one born as a genius—man's hard work and passion makes him a genius. CONTENTS: 1. Early Life 2. School Years 3. University Years 4. Post-University Years 5. Scientific Discoveries 6.

    In this lively and compact introduction, astrophysicist Andrew King reveals how the laws of physics force stars to evolve, driving them through successive stages of maturity before their inevitable and sometimes spectacular deaths, to end as remnants such as black holes. The book shows how we know what stars are made of, how gravity forces stars like the Sun to shine by transmuting hydrogen into helium in their centers, and why this stage is so long-lived and stable. Eventually the star ends its life in one of just three ways, and much of its enriched chemical content is blasted into space in its death throes. Every dead star is far smaller and denser than when it began, and we see how astronomers can detect these stellar corpses as pulsars and black holes and other exotic objects. King also shows how astronomers now use stars to measure properties of the Universe, such as its expansion. Finally, the book asks how it is that stars form in the first place, and how they re-form out of the debris left by stars already dead. These birth events must also be what made planets, not only in our solar system, but around a large fraction of all stars.

    . . . Wilczek writes with breathtaking economy and clarity, and his pleasure in his subject is palpable." --The New York Times Book Review One of our great contemporary scientists reveals the ten profound insights that illuminate what everyone should know about the physical worldIn Fundamentals, Nobel laureate Frank Wilczek offers the reader a simple yet profound exploration of reality based on the deep revelations of modern science. With clarity and an infectious sense of joy, he guides us through the essential concepts that form our understanding of what the world is and how it works. Through these pages, we come to see our reality in a new way--bigger, fuller, and stranger than it looked before.Synthesizing basic questions, facts, and dazzling speculations, Wilczek investigates the ideas that form our understanding of the universe: time, space, matter, energy, complexity, and complementarity. He excavates the history of fundamental science, exploring what we know and how we know it, while journeying to the horizons of the scientific world to give us a glimpse of what we may soon discover. Brilliant, lucid, and accessible, this celebration of human ingenuity and imagination will expand your world and your mind.
