Nuclear deterrence was the central organising mechanism for international security relations in the second half of the twentieth century. It has been replaced by a new global security environment in which the central role of deterrence, both nuclear and otherwise, appears to have diminished. This collection of papers attempts to draw conclusions on the current place of deterrence in international security relations.

A thorough introduction to modern classical and quantum optics, appropriate for advanced undergraduates or beginning graduates. The emphasis is on building an understanding in straightforward steps. Digital cameras, LCD screens, laser welding, and the optical fibre-based internet illustrate the penetration of optics in twenty-first century life: many such modern applications are presented from first principles. Self-contained themes covered in the book include: - Paraxial ray optics for devices including matrix methods and aberrations. - Interference, coherence and interferometry. -...

This book is intended for the use of final-year undergraduates and first-year postgraduates. One appendix is devoted to calculating the scattering amplitudes for fermion + fermion going to fermion + fermion, which is, if anything, the 'basic' process.
