	The Dual Nature of Light as Reflected in the Nobel Archive
		Arthur H. Compton in 1927 was entitled "X-rays as a Branch of Optics".
		Compton had followed up an observation that some parts of X-rays were scattered away from the beam direction with a longer wave length than the incoming radiation.
		Compton's discovery was by these scientists taken as the decisive proof for the truth of the corpuscular theory.

	WORLD OF ATOMS - "Properties of light"
		However, when the wave length of a light is diminished, its undular properties are attenuated and the quantum properties are shown.
		This phenomenon, which is termed as Compton's recoil, is impossible to explain by a wave theory of light.
		In quantum theory the magnification of wave length of radiation at a dispersion is explained by interaction of photons of impinging radiation with electrons of atoms and molecules.

		Compton appealed to the Court of Appeals on the sole ground that the postponement of the February 25 hearing violated his statutory rights and required dismissal of the petitions.
		Compton contends that the time requirements in Section 43-1-11(A) and Section 43-1-15(B) are mandatory and that the appropriate remedy for a violation of the time requirements is dismissal of the petition.

	Compton, Lee County, Illinois
		The history of Compton started when railroad tracks were laid through Brooklyn Township, one mile south of what was called, "the Burg" but officially known as the town of Melugin's Grove.
		Compton along with others now had the tedious work of moving their buildings a short distance to the new town which appropriately became known as Compton.
		The village of Compton received their charter from the State of Illinois in December of 1875 and held its first organized meeting on Jan. 14, 1876 and elected J.W. Swisher, W.W. Miller, M.M. Avery, G.W. Bradshaw, W.I. Guffin and Joel Compton as trustees.

		According to the ether model, light comprises two effects: It involves a triangular cavity at the front of the light quantum, and it involves a certain number of ether cubes, which turn, until the ether orientation is in line (or perpendicular) to the original orientation.
		Thereby the length of the bricks must be larger by a factor, containing the square of the ratio of the cross sectional dimension.
		The ratio of the cross sectional dimensions is equal to the "index of refraction", as well as to the ratio of "wave lengths", as the ratio of the speeds of light.

	UCLA PBPL - Inverse Compton Scattering
		is the temporal pulse length of the scattered x-rays, σ
		Because the pulse length is primarily determined by the electron bunch length, much longer laser pulses (picosecond and even nanosecond pulses) may be used to increase the effective interaction cycles between the electrons and undulator laser field, therefore increasing the number of photons scattered (x-rays produced) for each electron (eqn.'s 13and20) [2, 6].
		In this method, it is possible to use the physical imperfections of the interior of a waveguide to slow down faster electrons in the bunch and in effect compress it[3].

		I actually belive the smallest theorized length would be a one dim string which is on the order of 10^-34 cm you see it is nearing plancks constant I believe and therfore can't get any smaller.
		There is no current reason to suppose the Planck length is a sharp lower bound on length.
		What happens there is that the Compton wave length of a Planck mass particle equals its Schwartzschild radius, so gravity an quantum are forced to acknowledge each other.

	A Possible New Compton Effect
		In the case of the Compton Effect, it would be tough to present a persuasive argument though, regarding galactic red shifts.
		So, a single Compton Effect encounter might shift one of the lines of the Hydrogen spectrum by some red-shift, but the rest of the lines would not then be shifted.
		The main point of this essay is not really to "promote" the Compton Effect as THE explanation for all the large red shifts that are seen in apparently distant objects, but rather to suggest that there may be assorted alternate concepts worth considering.

	The Compton wavelength of the electron (Site not responding. Last check: 2007-09-21)
		The Compton wavelength of a particle, roughly speaking, is the length scale at which relativistic quantum field theory becomes crucial for its accurate description.
		The Compton wavelength of the electron is the characteristic length scale of QED (quantum electrodynamics).
		I strongly advise the reader to take the ratio of the Bohr radius by the Compton wavelength to see how much bigger the atomic length scale is than the length scale at which quantum field theory becomes really important.

		The wave lengths of the scattered rays are measured at the various deflection angles.
		The current interpretation of these results is as follows: The peak that has the same wave length as the incident x-ray is the result of photons colliding with the combined electrons of the carbon atom.

		Compton entered the field of X-ray research in 1913 and carried on active work until the 1930s, when he began to specialize in cosmic rays.
		Professor Compton's greatest discovery, for which he was awarded a Nobel Prize in 1927, was the Compton Effect.
		His work demonstrated that in the scattering of X-rays by electrons, the radiation behaves like corpuscles, and that the interaction between the X-ray corpuscles and the electrons in the scatter is completely described by the principles of the conservation of energy and momentum for the collisions of particles.

	Kierein's Erroneous Compton Model for the Redshift
		Kierein proposes that the Compton shift causes the redshift.
		Thus the Compton effect cannot explain the cosmological redshift which gives the same fractional change in wavelength at all wavelengths.
		If the total wavelength change of 185 nm is produced in steps of the Compton wavelength = 0.0024 nm, then 77,000 scatterings are needed and one would expect a standard deviation of sqrt(77,000) = 278 leading to a FWHM of sqrt(8ln2)278*0.0024 = 1.6 nm.
