Following the birth of the laser in 1960, the field of "nonlinear optics" rapidly emerged.

Today, laser intensities and pulse durations are readily available, for which the concepts and approximations of traditional nonlinear optics no longer apply. In this regime of "extreme nonlinear optics," a large variety of novel and unusual effects arise, for example frequency doubling in inversion symmetric materials or high-harmonic generation in gases, which can lead to attosecond electromagnetic pulses or pulse trains. Other examples of "extreme nonlinear optics" cover diverse areas such...

The reviews and highlights included in this book of proceedings of the plenary sessions, of the Joint European and National Astronomical Meeting (2002), cover some of the major fields and projects which will determine the research in astronomy in the next decades. The highlights have been presented by young astronomers from several European countries, selected from a list of proposals submitted by different institutions across Europe.

This book reflects the multi-disciplinarity and interaction that took place in the meeting. By including reviews on space and ground-based observational...

Relativistic Astrophysics and Cosmology offers a succinct and self-contained treatment of general relativity and its application to compact objects, gravitational waves and cosmology. The required mathematical concepts are introduced informally, following geometrical intuition as much as possible. The approach is theoretical, but there is ample discussion of observational aspects and of instrumental issues where appropriate.

The book includes such topical issues as the Gravity Probe B mission, interferometer detectors of gravitational waves, and the physics behind the angular power...

The Series

This new series is aimed at the same people as the Practical Astronomy Series - in general, active amateur astronomers. However, it is also appropriate to a wider audience of astronomically-informed readers. Because optical astronomy is a science that is rather at the mercy of the weather, all amateur astronomers inevitably have periods when observing is impossible. At such times they tend to read books about astronomy and related subjects. The Astronomers' Universe Series begins by assuming an appropriate level of knowledge. Basic information about the distance,...

In Miletus, about 550 B.C., together with our world-picture cosmology was born. This book tells the story. In Part One the reader is introduced in the archaic world-picture of a flat earth with the cupola of the celestial vault onto which the celestial bodies are attached. One of the subjects treated in that context is the riddle of the tilted celestial axis. This part also contains an extensive chapter on archaic astronomical instruments. Part Two shows how Anaximander (610-547 B.C.) blew up this archaic world-picture and replaced it by a new one that is essentially still ours. He taught...
