Albert Reimer 
Horizons in World Physics. Volume 272 

This book presents original research results on the leading edge of physics. Each article has been carefully selected in an attempt to present substantial research results across a broad spectrum. Some topics discussed include second harmonic generation in nonlinear optics research; pixel detectors in nuclear instruments; the empirical basis of quantum mechanics and the modern perspective, and a review of the Bohr-Sommerfeld semiclassical quantization rule.
