The book deals mainly with direct mass determination by means of a
conventional balances. It covers the history of the balance from
the beginnings in Egypt earlier than 3000 BC to recent
developments. All balance types are described with emphasis on
scientific balances. Methods of indirect mass determination, which
are applied to very light objects like molecules and the basic
particles of matter and celestial bodies, are included. As
additional guidance, today's manufacturers are listed and the
profile of important companies is reviewed. Several hundred
photographs, reproductions and drawings show instruments and their
uses. This book includes commercial weighing instruments for
merchandise and raw materials in workshops as well as symbolic
weighing in the ancient Egyptian's ceremony of 'Weighing of the
Heart', the Greek fate balance, the Roman Justitia, Juno Moneta and
Middle Ages scenes of the Last Judgement with Jesus or St. Michael
and of modern balances. The photographs are selected from the
slide-archives of the late Richard Vieweg (1896-1972) (former
President of the Physikalisch-Technische Bundesanstalt,
Braunschweig, Germany), of the late Hans R. Jenemann (1920-1966)
(former head of the Analytical Laboratory of Schott & Gen.,
Mainz, Germany) and of his wife Irene (1933-2008) and of Erich
Robens.
