Mass determination is of fundamental importance for science, technology and economics. Technical measuring systems range from ultramicro balances to weighing machines for freight trains; massive objects range from subatomic particles to galaxies. Comprehensive and topical, this reference work - edited by scientists of the Physikalisch-Technische Bundesanstalt, Germany - covers the whole field of mass determination. Starting from physical foundations, it describes virtually all measurement techniques in detail and gives a thorough overview over scientific experiments related to the determination of mass. Reports on contemporary problems, such as a new definition of the kilogram, historical excursions and an unparalleled list of references make this book an absolute must for everyone dealing with questions relating to mass determination in fundamental research, technical application, calibration service, and standardization, and also for teachers and historians.

Historical Dates
Technical measuring systems based on mass determination are of key importance for science, technology, and economics. Through historical and physical lenses, the editors from the Physikalisch-Technische Bundesanstalt in Germany comprehensively detail measurement techniques and overview experiments on the determination of mass in domains ranging from subatomic particles to galaxies. Showing that there is indeed something new in this field, they report on a new definition of the kilogram. Illustrations include Newton under the proverbial apple tree, balance equipment throughout the ages, and a satellite providing data on the Earth's gravitational field. Appendices cover additional material on definitions, units of measurement, formulas, and the gravitational acceleration and height above sea level of selected cities worldwide. Some of the references are in German.
