Einstein’s theories of special and general relativity together form a cornerstone of modern physics. Based on the notion of curved, four-dimensional spacetime, relativity helps to explain phenomena as diverse as time dilation, length contraction, mass-energy equivalence, the formation of black holes and the evolution of the Universe. Using clear and accessible language, and with numerous fully solved problems, this self-study guide is aimed at the general reader who wants to move beyond maths-lite popularisations and tackle the essential mathematics of this fascinating theory. For those with minimal mathematical background, the first chapter provides a crash course in elementary mathematics. The reader is then taken gently by the hand and guided through a wide range of topics including Newtonian mechanics, the Lorentz transformations, tensor calculus, the Schwarzschild solution, simple black holes and Friedmann-Robertson-Walker cosmological models. Understand even the basics of Einstein's amazing theory and the world will never seem the same again.

A straightforward, enjoyable guide to the mathematics of Einstein's relativity To really understand Einstein's theory of relativity – one of the cornerstones of modern physics – you have to get to grips with the underlying mathematics. This self-study guide is aimed at the general reader who is motivated to tackle that not insignificant challenge. With a user-friendly style, clear step-by-step mathematical derivations, many fully solved problems and numerous diagrams, this book provides a comprehensive introduction to a fascinating but complex subject. For those with minimal mathematical background, the first chapter gives 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, relativistic cosmology and gravitational waves. 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. "I must observe that the theory of relativity resembles a building consisting of two separate stories, the special theory and the general theory. The special theory, on which the general theory rests, applies to all physical phenomena with the exception of gravitation; the general theory provides the law of gravitation and its relations tothe other forces of nature." – Albert Einstein, 1919 Understand even the basics of Einstein's amazing theory and the world will never seem the same again.

Physics in 50 Milestone Moments is a lively, accessible, and thought-provoking introduction to physics, its history, and its practitioners. Uniquely, it is structured around a timeline of landmark events that vividly brings to life the evolution of this most fundamental science; from the Stone Age, through the classical era and the Renaissance, to the present day. As well as offering a comprehensive guide to physics, this book helps make the big ideas intelligible to us by placing them in their real-world contexts.

Gravity addresses the natural phenomenon that both philosophers and mathematicians have been curious about for centuries and the science that makes it all possible. It begins in the time of Aristotle, where the book explains why and how the evolution of thought contributed to the understanding of force, acceleration, and resistancethe early pieces to the puzzle of gravity. Once the basics have been established, the text dives headfirst into Albert Einsteins general theory of relativity and Sir Isaac Newtons law of universal gravitation in order to explain one of the universes greatest mysteries and the effects these discoveries have had on the world.
