Arguably more than any other book, *Einstein Plus Two* helped launch the dissident revolution of the 1990s. As a consequence of this book, Beckmann founded *Galilean Electrodynamics* in 1990, a time when several other dissident journals made their start. Beckmann's concept of the relativity principle without Einsteinian observer dependence serves as the major unifying theme. It stresses the idea of motion with respect to the local field rather than to the observer of special relativity theory.

The book is divided into three sections: Einstein Plus Zero, One and Two. In *Einstein Plus Zero*, Beckmann reexamines the historic experiments of Bradley, Fresnel, Fizeau, Airy, and of course, Michelson with Morley and Gale, and shows how understanding motion with respect to the local field makes sense of them all. In *Einstein Plus Zero*, he considers quantization of electron orbits, electromagnetic mass, the meaning of Planck's constant and the Schr?dinger Equation from a proper understanding of central motion. Finally in *Einstein Plus Two*, the large questions of gravitation, Mercury's perihelion, the Titius-Bode Series and inertia are addressed.

"There is so much to enjoy in this book. If you get your hands on this book, even for a moment, at least read the preface and the introduction. They are brilliant and short. His 'Grandiose Theory of the Railroad Track' shows Beckmann's humor and his insight. I also love Mr. Beckmann's simple statement that 'a theory that does not recognize the equality of action and reaction cannot, without apology, invoke the conservation of momentum.'"

It's the ratio between a circle's circumference and its diameter. And that's a constant, right? And there's never been a disagreement on what that constant is - or its value to science - right? Well, not exactly.

In this lucid, wide-ranging book, Petr Beckmann traces the perilous journey of pi - the little number with huge implications for advanced mathematical functions - from its Babylonian creation to its use by the Greeks in measuring to some medieval attempts to eradicate those who pursued it to its crucial role in modern computation. Beckmann reveals this journey to be nothing less than a mirror of human history. He tells of times when pi made progress, and alos when it was stifled by militarism and religious fanaticism.

The mathematical level of the book puts it within the grasp of the nonspecialist, and the author's popular approach to the subject will make it appealing to readers of all ages. - inside cover

This breezy book gives you the whole fascinating story, from the first Stone Age tally stick to the latest "intelligent" computers... with the thinkers, builders, navigators, martyrs and madmen along the way. Even if simple sums make you cross-eyed, this is one math book that will charm you from cover to cover... - *The Reader's Catalog*

This book is a monograph on the reflection or scattering of electromagnetic waves, particularly radio waves, from rough surfaces such as irregular terrain, rough layers in the troposphere, the rough surface of the sea, the rough surfaces of the moon and planets, etc. It is intended for scientists working in the fileds of radio wave propagation and electromagnetic theory, bu the theoretical part of the book may be equally useful for acousticians. It assumes a knowledge of mathematics and electromagnetic theory at the graduate level (Physics or Electrical Engineering), though the reader can be a newcomer without background in this particular subject, as the problem is treated from first principles and particular mathematical tools (e.g. Bessel Functions and the theory of random variables) are summarized in the appendix.

The book is divided into two parts. Part 1, "Theory" gives the general principles of the theory, in particular the solutions for periodic and random roughness. Part 2, "Application" applies this theory to the propagation of radio waves in irregular terrain over the rough surfaces of the sea, to tropospheric scateer propagation and to radar reflections from the moon.
