Product Description
The initial values are the source values of the particles in the quantum level, an internal quality, but they cannot be detected in measurements, probably due to the relative motion and mutual interaction existing between the particles in reality. In fact, laboratory measurements yield the relativistic reflection of the particles, without exposing the more basic level, concealed underneath. A formula composed of initial values fulfills the same known functional relation that exists between the experimental values, and produce quantitative results with a clear match. On one hand, it allows giving information on the origin of values known only from experiments, and on the other hand, it allows combining with new information, to identify and define unknown values. ...

The best (only! ) general physics data reference
This work, which I have just discovered to be out of print,
has been a reliable reference work for general physics data.
Because this work avoids antiquated measurement units such
as pounds, inches, gallons, and miles per hour, using it for
experimentation has been easy, as translation from one
realm of physics to another is coherent.
This is sadly lacking in so many other reference works.
It is a shame that this is no longer being printed,
as it would be a real boon to private experimenters around
the world if someone would carry on with this quality.
of reference material.
The scope of this book is what makes it so valuable. ... Read more

Product Description
Volume II/24 presents the spectroscopic data on diamagnetic and paramagnetic molecules as well as on molecular ions and radicals up to date considering the publications up to and partly including 1997. The spectroscopic information collected in this volume has been obtained principally from gas phase microwave measurements. Volume II/24 is a supplement to volumes II/4, II/6, II/14, and II/19 and is planned to appear in five subvolumes, the last of which will contain the substance index taking into account all molecules worked at since 1967 in the volumes mentioned and will provide cross references to and between all tables of these. The present subvolume II/24A contains the general introduction and tables of rotational and centrifugal distortion constants of diamagnetic diatomic, linear and symmetric-top molecules, i.e. data which roughly specifies the frequencies of the rotational transitions of these types of rotors. ...

Product Description
High Quality Content by WIKIPEDIA articles! Quantum electrodynamics (QED), a relativistic quantum field theory of electrodynamics, is among the most stringently tested theories in physics. Precision tests of QED consist of measurements of the electromagnetic fine structure constant, ?, in different physical systems. Checking the consistency of such measurements tests the theory. Tests of a theory are normally carried out by comparing experimental results to theoretical predictions. In QED, there is some subtlety in this comparison, because theoretical predictions require as input an extremely precise value of ?, which can only be obtained from another precision QED experiment. Because of this, the comparisons between theory and experiment are usually quoted as independent determinations of ?. QED is then confirmed to the extent that these measurements of ? from different physical sources agree with each other. ... Read more

Product Description
Since publication of the first edition of this book in 1988, interest in the optical properties of materials has continued to grow and there have been a number of important developments in the field. The aim of this second edition is to present an up-to-date and broad picture of the field of optical constants covering the theoretical background, experimental techniques and results for a wide range of materials (bulk and thin film) over a wide spectral range from soft x-rays to microwaves.
For the second edition Dr Ward has updated the book throughout. In particular, sections have been added on the optical properties of the sulphides, selenides and tellurides of cadmium, zinc and lead. Two other new sections deal with low dimensional structures, an important and relatively recent development area, and the sensitivities of different methods for measuring ^In, ^Ik and ^Id. A new Appendix giving tabulated values of optical constants for a large number of elements, insulators and semiconductors at two common laser wavelengths completes the second edition.
