	LORENTZ CONTRACTION. The Columbia Encyclopedia: Sixth Edition. 2000 (Site not responding. Last check: 2007-10-12)
		The Lorentz contraction hypothesis was put forward in an attempt to explain the negative result of the Michelson-Morley experiment of 1887 designed to demonstrate the earth’s absolute motion through space (see ether; relativity).
		The hypothesis held that any material body is contracted in the direction of its motion by a factor [radical], where v is the velocity of the body and c is the velocity of light.
		Although the Lorentz contraction did not succeed entirely in reconciling the results of the Michelson-Morley experiment with classical theory, it did serve as the basis for the mathematics of Einstein’s theory of relativity.

	George Francis Fitzgerald
		Fitzgerald was one of the minority of scientists who appreciated the full significance of Maxwell’s work and he began to push the theory forward.
		Fitzgerald was appointed tutor at TCD in 1877 and Professor of Natural and Experimental Philosophy in 1881.
		He proposed that moving bodies contract in the direction of motion and that the contraction cannot be measured because the measuring rods shrink in the same proportion.

	Hendrik Lorentz Summary
		Lorentz added a term to Maxwell's equations to account for the force of the magnetic field on these "electrons." If this theory were correct, Lorentz suggested, then the properties of light should be affected by an external magnetic field.
		Lorentz argued, for example, that electromagnetic radiation is produced by the vibration of the tiny charged particles, and this has turned out to be true of electrons.
		Lorentz decided that one way to explain the Michelson-Morley results was to assume that objects traveling through the aether (in which he continued to believe) underwent a shortening in length in the direction in which they were moving.

	FitzGerald
		George FitzGerald was a brilliant mathematical physicist who today he is known by most scientists as one of the proposers of the FitzGerald-Lorentz contraction in the theory of relativity.
		However, this suggestion by FitzGerald, as we shall see below, was not in the area in which he undertook most of his research, and he would certainly not have rated this his greatest contribution.
		FitzGerald was elected a Fellow of the Royal Society of London in 1883 and, like his father-in-law, he was to receive its Royal medal.

	Lorentz Contraction (Site not responding. Last check: 2007-10-12)
		The concept of the contraction was proposed by the Irish physicist George FitzGerald in 1889, and it was thereafter independently developed by Hendrik Lorentz of The Netherlands.
		FitzGerald and Lorentz attempted to preserve the classical concepts by demonstrating the manner in which space contraction of the measuring apparatus would reduce the apparent constancy of the speed of light to the status of an experimental artifact.
		Significant at speeds approaching that of light, the contraction is a consequence of the properties of space and time and does not depend on compression, cooling, or any similar physical disturbance.

		Lorentz developed his mathematical theory of the electron for which he received the Nobel Prize in 1902.
		Zeeman had verified experimentally Lorentz's theoretical work on atomic structure, demonstrating the effect of a strong magnetic field on the oscillations by measuring the change in the wavelength of the light produced.
		He possessed and successfully employed the mental vivacity which is necessary to follow the interplay of discussion, the insight which is required to extract those statements which illuminate the real difficulties, and the wisdom to lead the discussion among fruitful channels, and he did this so skillfully taht the process was hardly perceptible.

	Length contraction Summary
		Length contraction is one of the primary phenomena predicted by Albert Einstein's theory of special relativity published in 1905.
		Length contraction as a physical effect on bodies composed of atoms held together by electromagnetic forces was proposed by George Fitzgerald based on a paper by Oliver Heaviside in the 1880s and worked out in more detail by Hendrik Lorentz (1895, 1899) and Joseph Larmor (1897, 1900).
		Lorentz transformations play the same role in Minkowski geometry (the Lorentz group forms the isotropy group of the self-isometries of the spacetime) which are played by rotations in euclidean geometry.

	ricker2
		He uses the inverse Lorentz transform in place of the Lorentz transform, and he discards the condition x=vt and replaces it with the condition that time is evaluated at x’=0.
		Equations 11 and 13 are interpreted in terms of the Lorentz contraction hypothesis, which explains the null result of the Michelson-Morley experiment as a physical contraction of the experimental apparatus.
		Lorentz did this using only one evaluation and the result is a theory applicable to the aether interpretation.

	Special Relativity (Site not responding. Last check: 2007-10-12)
		Lorentz wrote a paper in 1886 where he criticised Michelson's experiment and really was not worried by the experimental result which he dismissed being doubtful of its accuracy.
		Lorentz was unaware of FitzGerald's paper and in 1892 he proposed an almost identical contraction in a paper which now took the Michelson-Morley experiment very seriously.
		While Lorentz must be considered as the first to have found the mathematical content of the relativity principle, Einstein succeeded in reducing it to a simple principle.

	Inconsistency of Lorentz Transforms With Einstein Relativity Postulates
		The essence of the proof that necessary and sufficient conditions are not fulfilled in Einstein relativity is that the Lorentz transformations are not mathematically bijective transformations.
		This arises because the Lorentz and inverse Lorentz transformations are mathematically inconsistent.
		The inconsistency in the Lorentz and inverse Lorentz transforms occurs because light velocity in an absolute sense, i,e, that the same measurement scale is used in both frame S and S’, is inconsistent with the fact that the Lorentz transform changes the measurement scales.

		G.F. Fitzgerald concluded that objects grow shorter in the direction of their absolute motion due to the pressure of the "aether wind" (the "Fitzgerald Contraction"equation).
		Lorentz manipulated this equation, which is now called the "Lorentz-Fitzgerald Contraction" or "Lorentz Transformation".
		The Fitzgerald Contraction equation for length contraction appears within both the antenna radiation equation and the new model of the hydrogen atom derived by Dr. Vlasak.

		Lorentz was a Dutch physicist and the winner of the 1902 Nobel Prize in Physics for his work on electromagnetic radiation.
		In 1895 in an attempt to explain the Michelson-Morley experiment, Lorentz proposed that moving bodies contract in the direction of motion; George FitzGerald had arrived at this conclusion independently.
		These mathematical formulas describe basic effects of the theory of Special Relativity, the increase of mass, shortening of length, and time dilation that are characteristic of a moving body.

		Observers in motion: A simple-minded derivation of the Lorentz Transform.
		The Lorentz transform applied to the 4-vector (a,A) doesn't change the latter and specifies the interrelated transformations of the time coordinate (a) and of the "parallel" spatial coordinate (A.
		A linear transformation which preserve spacetime intervals (while respecting the orientation of space and the direction of time) is necessarily a composition of such a boost with a spatial rotation (which leaves time unchanged and preserves spatial distances without changing the orientation of space).

	Understanding Physics (Michael Mansfield and Colm O' Sullivan)
		The Lorentz transformations are derived in section 9.4 to enable transformations between reference frames to be made in a manner which, unlike the Galilean transformations, is consistent with the direct connection between space and time coordinates which is introduced by the Principle of Relativity.
		The transformations are used, in sections 9.5 and 9.6, to examine the Fitzgerald-Lorentz contraction and time dilation, respectively, and examples of their use are given in problems 9.2 to 9.6.
		The Lorentz velocity transformations are derived in section 9.9 and examples of their use are given in this section, in worked example 9.1 and problems 9.7 to 9.9.

	Can You See the Lorentz-Fitzgerald Contraction?
		Oddly enough, though Einstein published his famous relativity paper in 1905, and Fitzgerald proposed his contraction several years earlier, no one seems to have asked this question until the late '50s.
		To understand the how the appearance of the night sky (apparent positions of stars and galaxies on the celestial sphere) is altered by a Lorentz transformation, we must look at null lines (one dimensional subspaces spanned by null vectors).
		Lorentz transformations may be classified into four types according to their geometric effect on the night sky:

		This is a complement of these papers; it brings more proofs of the fact, that Fitzgerald Lorentz contraction is an error, and it extends, a little, the matters, in which a modification of physical theory is needed.
		Fitzgerald-Lorentz contraction has been easily admitted, because at that time it was not known, that the equivalent of a unit of matter is c2 units of energy.
		The author is clearly under the impression that the Lorentz contraction is a sort of physical "squeezing" and not just an effect of looking at the same events from a different viewpoint.

	Alternate View--Analog
		They said that when an object, like a spaceship, is moving at a very high percentage of the speed of light, then the “time dilation” becomes pronounced and it’s possible to go to a star 20 light years distant and yet only age a few years.
		We’ll leave the facts (such as they are) about time dilation to another column, but in the case of length contraction, it is not at all the case that the spaceship will necessarily look contracted.
		We then also have a clear answer to why the retarded field theory, without using Lorentz contraction for determining the effective shape of a moving charge, yields relativistically correct fields of the charge.

	Re: Can you provide the Lorentz-Fitzgerald contraction transforms
		Actually, E=mc^2 isn't a lorentz transformation at all -- it's one of the 4 equations relating energy/momentum to velocity and mass.
		A lorentz transformation, on the other hand, takes a spacetime vector in one coordinate system (t,x,y,z) and transforms it into the same vector as seen by another coordinate system (t',x',y',z').
		There are 4 equations, one for each component, but the transformations have nothing to do with E=mc^2.
