دانلود کتاب Encyclopaedia of Scientific Units, Weights and Measures: Their SI Equivalences and Origins

توضیحاتی در مورد کتاب به زبان اصلی :

Mankind has a fascination with measurement. Down the centuries we have produced a plethora of incompatible and duplicatory systems for measuring everything from the width of an Egyptian pyramid to the concentration of radioactivity near a nuclear reactor and the value of the fine structure constant. With the introduction first of the metric system and of its successor the Système International d'Unités (SI), the scientific community has established a standard method of measurement based on only seven core units.

The Encyclopaedia of Scientific Units, Weights and Measures converts the huge variety of units from all over the world in every period of recorded history into units of the SI. Featuring:
- An A - Z of conversion tables for over 10,000 units of measurements.
- Tables of the fundamental constants of nature with their units.
- Listings of professional societies, and national standardization bodies for easy reference.
- An extensive bibliography detailing further reading on the multifarious aspects of measurement and its units.

This huge work is simply a "must have" for any reference library frequented by scientists of any discipline or by those with historical interests in units of measurement such as archaeologists.
