This is the second book in the Everyone’s Guide Series devoted to Einstein’s Theory of Special Relativity. Relativity and Quantum Mechanics are the two major pillars of 20th century physics, which together revolutionized our understanding of nature, utterly dismantling Newtonian physics that had been the gold standard of science for over 200 years, and introducing radically new concepts that defy human intuition. These theories may represent the greatest upheaval in the history of science. Both Relativity and Quantum Mechanics were launched over 100 years ago, yet we are still digesting their broad and stunning implications. Both theories have been exhaustively tested and confirmed to extraordinary precision. As bizarre as they may seem at first, there is no denying that they describe our world as it really is.In this book, we will discuss: spacetime, Einstein’s unification of space and time; the Lorentz Contraction and Transform; relativistic mass and Einstein’s most famous equation E=mc2; light cones past and future; causality and simultaneity; and the impact of Relativity on space travel. Also included are helpful math tricks that simplify problem solving. In later eBooks on Special Relativity in the Everyone’s Guide Series, we’ll explore advanced topics, including: magnetism as a relativistic effect; the Twin Paradox and other notorious relativistic puzzles.
