REVIEW OF THE BOOK: WALDEMAR NAWROCKI, INTRODUCTION TO<br /> QUANTUM METROLOGY (IN POLISH)
Journal Title: Metrology and Measurement Systems - Year 2008, Vol 15, Issue 3
Abstract
Quantum metrology is a field of theoretical and experimental study of high-resolution and high-precision methods of measurement of physical parameters based on quantum mechanics, and particularly exploiting quantum entanglement. Without equivalent in classical mechanics, quantum entanglement of particles or other quantum systems is an unusual phenomenon in which the state of a system is determinable better than the state of its parts. Attempts are made to use new measurement strategies and physical systems in order to attain measurement precision never achieved so far.

REVISING THE SI: THE JOULE TO REPLACE THE KELVIN AS A BASE UNIT
The joule is proposed to replace the kelvin in the set of SI base units. Arguments in favour of such replacement are presented, including improved standard accuracy and unit system coherence. The joule is also proposed t...
SIMULATION OF KARMAN VORTEX STREET DEVELOPMENT USING A NEW MODEL
The article is devoted to the simulation of the Karman vortex street using an analytical model. The model has been described in detail in [1]. Fundamental quantities like velocity driving the vortex, vortex rotation and...
