There are few topics more awe-inspiring than cosmology. What is the universe? How does it work? Where did it come from? These fundamental questions intrigue adults and children alike. This accessible guide brings alive humanity s attempts to explain the existence of everything and explores the latest and best theories on how the universe came into being. With approachable text, assuming no previous knowledge, and uniquely in such an illustrated book, the reader is taken beyond the certainties to explore the strange concepts that fill modern cosmology. Is the universe a hologram? Is everything we know part of a membrane floating in multidimensional space? Could we be living in a computer simulation? It sounds like science fiction, but these are among the ideas cosmologists seriously propose for the nature of reality. This book is for students, amateur astronomers, and anyone who has looked up at the sky and wondered about our place in the universe.

Vesmír se řídí souborem fyzikálních zákonů, z nichž nejznámější, ale také nejzáhadnější je gravitace. Gravitace jako univerzální interakce formuje planety, hvězdy, galaxie i celý vesmír. Bez ní by nevznikl ani život na Zemi. Tato kniha se vydává po stopách této tajemné síly od počátečních představ antických Řeků přes Newtonův gravitační zákon až po moderní strunovou a twistorovou teorii, smyčkovou kvantovou gravitaci a další hypotézy. Pochopení podstaty gravitace je klíčem k pochopení vlastností času, prostoru a hmoty a klíčem k poznání stavby vesmíru.

Weaving together the great ideas of science, The Reality Frame takes us on a thrilling journey from empty space all the way to the human mind. Acclaimed science writer Brian Clegg builds up reality piece by piece, from space, to time, to matter, movement, the fundamental forces, life, and the massive transformation that life itself has wrought on the natural world. He reveals that underlying it all is not, as we might believe, a system of immovable absolutes, but the ever-shifting, amorphous world of relativity. From religion to philosophy, humanity has traditionally sought out absolutes to explain the world around us, but as science has developed, relativity has swept away many of these certainties, leaving only a handful of unchangeable essentials - such as absolute zero, nothingness, light - leading to better science and a new understanding of the essence of being human. This is an Ascent of Man for the 21st century, the gripping story of modern science that will fill you with wonder and give you a new insight into our place in the universe.

Is the Brexit vote successful big data politics or the end of democracy? Why do airlines overbook, and why do banks get it wrong so often? How does big data enable Netflix to forecast a hit, CERN to find the Higgs boson and medics to discover if red wine really is good for you? And how are companies using big data to benefit from smart meters, use advertising that spies on you and develop the gig economy, where workers are managed by the whim of an algorithm? The volumes of data we now access can give unparalleled abilities to make predictions, respond to customer demand and solve problems. But Big Brother's shadow hovers over it. Though big data can set us free and enhance our lives, it has the potential to create an underclass and a totalitarian state. With big data ever-present, you can't afford to ignore it. Acclaimed science writer Brian Clegg - a habitual early adopter of new technology (and the owner of the second-ever copy of Windows in the UK) - brings big data to life.

Developments in physics and physics-based engineering have led to some of the biggest transformations in the way we live out lives. Here, we journey back to ten separate days in history for a closer look at the breakthroughs that have shaped the modern world. From Isaac Newton's law of motion, to Michael Faraday's electrical field theory, as well as Maxwell's equations that make TV, radio and cellphones possible. Comprising perfectly pitched science writing enlivened with a wealth of fascinating biographical detail, this eye-opening book is a celebration of power of physicists to bring about far-reaching, life-transforming change.

Brian Clegg was always fascinated by Isaac Asimov's classic Foundation series of books, in which the future is predicted using sophisticated mathematical modelling of human psychology and behaviour. Only much later did he realise that Asimov's 'psychohistory' had a real-world equivalent: game theory. Originating in the study of probabilistic gambling games that depend on a random source - the throw of a dice or the toss of a coin - game theory soon came to be applied to human interactions: essentially, what was the best strategy to win, whatever you were doing? Its mathematical techniques have been applied, with varying degrees of wisdom, to fields such as economics, evolution, and questions such as how to win a nuclear war. Clegg delves into game theory's colourful history and significant findings, and shows what we can all learn from this oft-misunderstood field of study.
