	Parity
		Parity is an important idea in quantum mechanics because the wavefunctions which represent particles can behave in different ways upon transformation of the coordinate system which describes them.
		In a famous experiment by C. Wu, the non-conservation of parity in beta decay was demonstrated.
		Their prediction was quickly tested when C. Wu and collaborators studied the beta decay of Cobalt-60 in 1957.

		Moreover, with both dialing parity and number portability, customer inconvenience represents the barrier to effective competition Congress intends to eliminate, whether that inconvenience results from the dialing of extra digits in the case of dialing parity, or notification of family, friends and business contacts when a customer is forced to change his or her number.

	DES Parity check system - Patent 4262358
		The parity system provides for simultaneous parity checks on a plurality of bytes where the bits of each byte are distributed through the algorithm shift register in a pseudorandom pattern.
		The parity tree comprising exclusive OR gates 240, 242, 244, 246, 248, 250, and 252 are utilized to check the odd number bytes in registers C, D and the parity register.
		Second, the bit inputs to the parity trees must be shifted from bits 4 and 5 of the D register to bits 8 and 9 of the C register between the fifth and sixth algorithm steps.

		The sum of the corrections is of the form A ln(lambda /sub C//r/sub 0/)+B, where A and B are functions of Z alpha, and lambda /sub C/ and r/sub 0/ are the Compton wavelength and the nuclear radius, respectively.
		We demonstrate that the radiative corrections to this effect due to the vacuum fluctuations of the characteristic size larger than the nuclear radius r0 and smaller than the electron Compton wavelength C are enhanced because of the strong electric field of the nucleus.

	CERN Courier - In hot pursuit of CP violati - IOP Publishing - article
		Parity conservation is the apparently innocuous proposition that the laws of physics are the same, or symmetric, when spatially inverted (the parity operation, P), as in a mirror-image world.
		Prompted by the realization of T D Lee and C N Yang that there was no experimental evidence that weak interactions conserved parity, C S Wu and collaborators discovered in 1957 that weak interactions do not conserve parity in the radioactive decay of cobalt-60.
		Parity violation could be attributed to an intrinsic feature of weak interactions, but CP violation was a mystery.

	CP violation
		CP violation is the violation of the combined conservation laws associated with charge conjugation (C) and parity (P) by the weak nuclear force, which is responsible for reactions such as the decay of atomic nuclei.
		The antiparticle of an electrically neutral particle may be identical to the particle, as in the case of the neutral pi meson, or it may be distinct, as with the antineutron.
		Parity, or space inversion, is the reflection in the origin of the space coordinates of a particle or particle system; i.e., the three space dimensions x, y, and z become, respectively, -x, -y, and -z.

		So (excluding the parity bit of cource) maybe you have 3 [ones] bit in the received byte, then the parity bit is (should be :-)) set to '1', to achive an even number of bits.
		Even parity is the one-bit sum of all the bits, and odd parity is the complement of that.
		Therefore the even parity is 0 iff there are an even number of 1 bits in the string of bits being tested.

	M5410 Coding Theory II
		Let C be a code (not necessarily linear) over a q-ary alphabet, i.e., C is a subset of V(n,q).
		Therefore, w(c) >= s, and since c is an arbitrary non-zero codeword of the linear code C it follows that the minimum non-zero weight of a codeword is >= s.
		It follows easily from the theorem that a linear code C with parity-check matrix H has minimum distance (exactly) d if and only if every set of d-1 columns of H are linearly independent, and some set of d columns are linearly dependent.
