The idea for this book began over four decades ago when Edward Teller began teaching physics appreciation courses at the University of Chicago. Then, as now, Dr. Teller believes that illiteracy in science is an increasingly great danger to American society, not only for our chil dren but also for our growing adult population. On one hand, the future of every individual on this globe is closely related to science and its applications. Fear of the results of science, which has become prevalent in much of the Western World, leads to mistaken decisions in important political affairs. But this book speaks of no fears and of no decisions-only of the facts that can prevent one of them and indirectly guide the others. From the perspective of this book, a second point is even more vii viii PREFACE significant. The first quarter of this century has seen the most won derful and philosophically most important transformation in our thinking. The intellectual and aesthetic values of the points of view of Einstein and Bohr cannot be overestimated. Nor should they be hidden at the bottom of tons of mathematical rubble. Our young people must be exposed to science both because it is useful and because it is fun. Both of these qualities should be taken at a truly high value."

In Conversations on the Dark Secrets of Physics, Teller returns to the fundamentals of physics to share with readers his unbridled enthusiasm for the world of physical reality--from the nature of molecules to quantum mechanics and superconductors, from the elementary laws of thermodynamics to how planets, asteroids, and comets develop their orbits. By simplifying the math and forgoing the often-confusing technical jargon, Teller helps the reader break through physic's bewildering formulas and equations and get to the wonders of our physical universe. A timeless and personal explanation of the importance of physics in our life, Conversations on the Dark Secrets of Physics is certain to become a classic.
