Explaining the Universe

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.

"Charap cuts a wide swath through the physical universe, from the physics of the very large to the physics of the very small. . . . The book is very readable and has excellent photographs and illustrations. It introduces the reader to a broad range of topics from the physical universe on the cutting edge of research."

"The scope of this book is certainly ambitious. Charap attempts to cover all the crucial developments of modern physics in the 20th century. He . . . gives the whole endeavor a robustness that reflects his joy and pride at taking part in such an intellectual exercise. . . . Explaining the Universe is . . . peppered with wonderful historical anecdotes about the (mainly) men who made these discoveries. These stories help to make the book a good read."---Pedro Ferreira, Physics World

"Among the slew of popular treatments of modern physics, Charap's effort distinguishes itself by accenting the provisional character of scientific theory. . . . Science students will find the author's palpable curiosity enticing."

"A well-informed, accessible and appropriately non-mathematical guide to the great theories of modern physics, quantum theory and relativity."---Graham Farmelo, New Scientist

"An engaging read. . . . This is more than a simple history of physics--it is the story of our changing view of the universe."---Ignacio Birriel, Astronomy
