Extractions: HOME SITE HELP ABOUT SEARCH ... EDUCATIONAL Nobel Lecture, June 3, 1920 The question of the composition of perceptible objects is one which already occupied the mind of the ancient Greeks. They formed the concept, as a philosophical speculation, of the indivisible particle, the atom, as the smallest component of perceptible objects. However, they did not pass beyond this stage of the hypothesis; they did not bring it to productivity through experimental research. It is otherwise with the mind of the Germanic peoples. They proceeded from the experience of their chemical dealings with matter, established the existence of a number of basic substances, or chemical elements, which could not be decomposed further, and proposed the hypothesis that a chemical element consists of homogeneous individuals, or atoms, which are responsible for the peculiar properties of the element, and which with the aid of chemical methods can neither be broken down further nor distinguished from one another. Towards the end of the last century a certain torpidity fell upon this concept of the chemical atom. Its verification in thousands of chemical experiments led to the belief that the chemical atom not only could not be decomposed into further parts by familiar chemical methods, but that it was completely and absolutely indivisible. Moreover, the abundance of chemical compounds and their importance in daily life hindered the chemist from investigating the question, in what does the individuality of the atoms of different elements consist. In the last three decades the concept of the chemical atom has been set free from this torpidity by our experiences in physics. The discovery of various phenomena has led to a recognition of the fact that the chemical atom is an individual which again is itself made up of several units into a selfcontained whole.

Extractions: Hydrogen Hydrogen has one electron, so it is the simplest of the elements in terms of its spectrum. Like other elements Hydrogen has discrete emission or absorption lines which result when the electron move between energy levels. Note, to move "up" a level, a photon of exactly the correct energy (or wavelength) is required.

The states shown in the left two images seem regular, the right two are chaotic. In the third picture the state lies mostly along a periodic orbit; in the fourth, it does not and is difficult to interpret, except for the four mirror symmetries with respect to the vertical horizontal and two diagonal lines.

http://www.bnrmetal.com/groups/col.htm

Extractions: The style of atmospheric hardcore-influence noise used to be more or less the domain of a single band, that being Neurosis , though other bands more in the hardcore field have delved in this area at times. Cult Of Luna is a newer band that has nailed the Neurosis style to a T, with the same sort of drawn-out, slow-building songs culminating in ferocious dissonant guitars and tortured vocals that usually are mixed slightly behind the instruments. As Neurosis has been a BNR favorite for some time, it will come as no surprise that this band also comes highly recommended. Though it's tempting to downgrade the band as their sound is so close to that of Neurosis, the fact is that few bands play this style, and it's not an easy style to grasp, and Cult Of Luna do it almost as well as the masters.

Extractions: STATIONARY STATES or wave patterns, associated with the energy levels of a Rydberg atom (a highly excited hydrogen atom) in a strong magnetic field can exhibit chaotic qualities.

In the third picture the state lies mostly along a periodic orbit; in the fourth, it does not and is difficult to interpret, except for the four mirror symmetries with respect to the vertical horizontal and two diagonal lines. Quantum Chaos Martin Gutzwiller, Scientific American , January 1992 POINCARE SECTION OF A HYDROGEN ATOM in a strong magnetic field has regions where the points of the electron's trajectory scatter wildly, indicating chaotic behavior. The section is a slice out of phase space, an abstract six-dimensional space: the usual three for the position of a particle and an additional three for the particle's momentum. MECHANICS is traditionally (and artificially) divided into the three compartments depicted here, which are linked together by several connections. Quantum chaos is concerned with establishing the relation between boxes P and Q. The spectrum of a chaotic quantum system was first suggested by Eugene P. Wigner, another early master of quantum mechanics. Wigner observed, as had many others, that nuclear physics does not possess the safe underpinnings of atomic and molecular physics: the origin of the nuclear force is still not clearly understood. He therefore asked whether the statistical properties of nuclear spectra could be derived from the assumption that many parameters in the problem have definite, but unknown values. This rather vague starting point allowed him to find the most probable formula for the distribution. Oriol Bohigas and Marie-Joya Giannoni of the Institute of Nuclear Physics in Orsay France, first pointed out that Wigner's distribution happens io be exactly what is found for the spectrum of a chaotic dynamic system.

Nationalencyklopedin Rydberg constant (symbol R ), fundamental constant of atomic physics that appears in the formulas developed (1890) by the Swedish physicist J. R. Rydberg, describing the wavelenghts or frequencies of light in various series of related spectral lines, such as those emitted by hydrogen atoms. The value of this constant is based on the premise that the nucleus of the atom emitting light is exceedingly massive compared with a single orbitting eletron (hence the infinity symbol The value of the Rydberg constant R is per metre, or per centimetre. When used in this form in the mathematical description of series of spectral lines, the result is the number of waves per unit length, or the wave numbers. Multiplication by the speed of light yields the frequencies of the spectral lines. Rydbergs konstant R m Nationalencyklopedin
