McKay T.C. Physical Measurements in Sound, Light, Electricity and Magnetism
Berkeley: Stanley-Taylor Company, 1908, 196 p.

This book is primarily intended as a text-book in physical measurements and a laboratory manual for second year students in physics at the University of Califoia. At this institution there is offered to first year students a laboratory course in mechanics, properties of matter, and heat. The subjects considered in this book are therefore Sound, Light, Electricity, and Magnetism. The experiments here described have been chosen for the most part because they have proved to be valuable exercises in elementary laboratory courses given by instructors in physics at the University of Califoia. A number of the experiments in this book have been described by Professor Drew, now of Leland Stanford University. Professor Hall of the University of Califoia and Professor Minor of the University of Nevada have also contributed greatly to the development of the course. The writer has drawn upon several years experience at the University of Califoia, as well as upon his previous experience at Harvard University, in the endeavor to select the most valuable experiments for an elementary laboratory course in the subjects of which this book treats. As compared with the books issued by the writer's predecessors the sections on Electricity and on Sound have been enlarged. In the treatment of the subject of Electrostatics the writer is indebted to Professor Noack for his careful descriptions in his ''Elementare Messungen aus der Electrostatik." Considerable use has also been made of Poynting and Thomson's ''Sound" A description of the principal types of sensitive galvanometers has been given in the section on Electricity, with a short discussion of the conditions of greatest sensitiveness for these instruments.

Springer-Verlag Berlin, 2005, 401 pages Time-correlated single photon counting (TCSPC) is a remarkable technique for recording low-level light signals with extremely high precision and picosecond-time resolution. TCSPC has developed from an intrinsically time-consuming and one-dimensional technique into a fast, multi-dimensional technique to record light signals. So this reference and text describes how advanced TCSPC techniques work and demons...

Surface Science Reports 59 (2005) p.1–152 The atomic force microscope (AFM) is not only a tool to image the topography of solid surfaces at high resolution. It can also be used to measure force-versus-distance curves. Such curves, briefly called force curves, provide valuable information on local material properties such as elasticity, hardness, Hamaker constant, adhesion and surface charge densities. For this reason the measurement of force cur...

North-Holland, Amsterdam, 1988, 399 p., (анг. яз. ) The advent of germanium and silicon detectors in the 1960's has revolutionized gamma- and X-ray spectrometry. The excellent energy resolution of these semiconductor detectors has been the basis for rapid and sometimes step-like progress. Today there is scarcely a field in natural science to which spectrometry with semiconductor detectors has not gained entry. The authors estimate that worldwide...
