Explaining the Universe

In this book, a distinguished scientist gives an inside view of the advances of the last century and those that will happen in the next. It is a joy to read. The story is interesting, and John Charap knows how to tell it. -- Mark Kidger, author of "Star of Bethlehem: An Astronomer's View" John Charap introduces the reader to the wonderfully broad range of topics of active research in physics. This book will be inspiring and instructive for students who might be persuaded to look more deeply into physics... Charap enlivens his text with charming anecdotal illustrations. My favorite is the use of a croissant as an example of classical chaos. -- P.J.E. Peebles, author of "Principles of Physical Cosmology and Quantum Mechanics"

Offers a view of the physicist's world. Providing a review of the 20th century's transformation of physics, this work checks in on the findings from particle physics, astrophysics, chaos theory, and cosmology. It explains how superstring theory may unite quantum mechanics with general relativity to produce a consistent quantum theory of gravity.In this fascinating book, John Charap offers a panoramic view of the physicist's world as the twenty-first century opens--a view that is entirely different from the one that greeted the twentieth century. We have learned that the universe is billions of galaxies larger than we imagined--and billions of years older. We know more about how it came to be and what it is. Because of physics, we live in a world of greater danger and more convenience, smaller particles and bigger ideas. Charap introduces these ideas but spares us the math behind them. After a review of the twentieth century's thorough transformation of physics, he checks in on the latest findings from particle physics, astrophysics, chaos theory, and cosmology. His tour includes ongoing efforts to find the universe's missing matter and to account for the first moments after the big bang. Taking readers right to the field's speculative edge, he explains how superstring theory may finally unite quantum mechanics with general relativity to produce a consistent quantum theory of gravity. Along the way, Charap poses the questions that continue to inspire research. Why is the universe flat? Why can't we forecast weather better? Can Schrodinger's cat really be simultaneously dead and alive? Why does fractal geometry keep showing up in strange places? Might spacetime have eleven dimensions? What does quantum mechanics mean about the nature of our world? In this book's pages, the nonphysicist will accept as commonsensical Heisenberg's uncertainty principle, and physicists can meet across specialties. Students can access physics' critical concepts, and poets can learn a new language to describe the universe's many wonders. Taking us from the ultraviolet catastrophe that undid the Newtonian world to tomorrow's Theory of Everything, Charap brings today's most fascinating science down to Earth, where we can all enjoy it.
