  Acoustical Society of America - The Wave Theory of Sound
The analogy with water waves was strengthened by the belief that air motion associated with musical sounds is oscillatory and by the observation that sound travels with a finite speed.
The mathematical analysis was limited to waves of constant frequency, employed a number of circuitous devices and approximations, and suffered from an incomplete definition of terminology and concepts.
The theory ultimately proposed for sound in the eighteenth century was incomplete from many standpoints, but modern theories of today can be regarded for the most part as refinements of that developed by Euler and his contemporaries.

 The Wave Theory of Light   (Site not responding. Last check: 2007-10-20)
Before the wave theory was established as the canonical explanation of optical phenomena, scientists involved in debates over the production and the interpretation of these phenomena could be divided into two groups: emissionists and wave theorists.
In other words, to be considered a competent wave theorist at this time required an understanding not only of light as ethereal disturbance, but also of the nature of rays and their relation to light beams.
But because, with wave theory, a beam of light is not considered a collection of rays in the first place, the rays (as we're using them here) have only an analytic significance.

 Wave Theory for Glider Pilots   (Site not responding. Last check: 2007-10-20)
The shape of the wave may be controlled by other factors and, as is illustrated later, the horizontal wind speed is itself modified by the shape of the wave.
Wave flow was set off by a redge whose shape was defined by a convenient mathematical formula which produces a bell shaped obstruction to the horizontal airflow.
The waves are not symmetrical, they tilt forward at a marked angle to the vertical and in certain sections the streamlines are practically vertical ahead of the wave crest but have only a gentle slope on the downstream side.

 TEW--The Theory of Elementary Waves
The theory is `automatically' relativistic; that is, the constancy of the velocity of light c relative to all observers follows as an immediate consequence of the new quantum theory, which constancy thus acquires a simple physical explanation.
The elementary waves theory yields a quantitative resolution of the EPR paradox[4].
Wave entanglements are generally viewed as being essential to the description of identical particle phenomena and to the entire structure of quantum mechanics; so it may strike the reader as absurd to try to account for multi-particle effects without them.

 Introduction to Elliot Waves   (Site not responding. Last check: 2007-10-20)
Wave "2" is a retracement of wave "1".
Wave "5" is final stage of the advance and often shows a divergence with such technical indicators as cumulative volume and relative strength (RSI).
Identifying waves is often a difficult activity because there are a number of exceptions and variations in the waves.

 Quantum Theory and Wave/Particle Duality
The object of this article is to examine the core assumptions behind this wave/particle idea with a view to developing a different model that is consistent with relativity, observation and the mathematical formalism.
At the time the theories were developed, wave propagation effects were the only mechanism that people were aware of that could produce those kinds of phenomena.
Because it is conventionally assumed that a particle propagates as a wave, Psi is normally taken to be a mathematical representation of the simultaneous superposition of states available to the particle.

 Elliott Wave Theory
Wave 4 should not overlap with Wave 1, except for wave 1, 5, a or c of a higher degree.
Sometimes, the momentum at Wave 5 is so weak that the 2nd and 4th sub-waves overlap with each other and evolved into diagonal triangle.
In some other circumstances, the Wave 5 is so weak than it even cannot surpass the top of the wave 3, causing a double top at the end of the trend.

 Invest FAQ:Technical Analysis:Elliott Wave Theory
This is an important point: Elliott Theory measures sociological performance of the masses and these sociological functions are so ingrained that even if individuals or many individuals are able to understand and dismiss those actions the majority of the people will not be able to.
It states that in general there will be 5 waves in a given direction followed by usually what is termed and ABC correction or 5 waves in the opposite direction.
This wave tends to be weak because their are usually more people that are still bullish on the stock and after some profit taking comes wave 5.

 Modern History Sourcebook: Sir WilliamThomson (Lord Kelvin): Wave Theory Of Light, 1884
The wave - length of light is the distance from crest to crest of the wave, or from hollow to hollow.
The variation in wave length between the most extreme rays is in the proportion of four and a half of red to eight of the violet, instead of four and eight; the red waves are nearly as one to two of the violet.
The length of this wave then is the 532d part of the four hundredth of a centimetre which would be the 21,280th of a centimetre, say the 21,000th of a centimetre.

 Bohmian Mechanics
In classical Hamilton-Jacobi theory we also have this equation for the velocity, but there the Hamilton-Jacobi function S can be entirely eliminated and the description in terms of S simplified and reduced to a finite-dimensional description, with basic variables the positions and the (unconstrained) momenta of all the particles, given by Hamilton's or Newton's equations.
The theory is defined by the axioms governing the behavior of the basic observables -- Newton's equations for the positions or Hamilton's for positions and momenta.
Since quantum theory itself, by virtue merely of the character of its predictions concerning EPR-Bohm correlations, is irreducibly nonlocal (see Section 2), one might expect considerable difficulty with the Lorentz invariance of orthodox quantum theory as well with Bohmian mechanics.

 Elliott Wave Theory
Theory named after Ralph Nelson Elliott, who concluded that the movement of the stock market could be predicted by observing and identifying a repetitive pattern of waves.
Based on rhythms found in nature, the theory suggests that the market moves up in a series of five waves and down in a series of three waves.
The key difference between the Elliott Wave Principle and other cyclical theories is that this theory suggests no absolute time requirements for a cycle to complete.
