Quaternions

130; In mathematics, quaternions are a non-commutative extension of complex numbers. They were first described by the Irish mathematician Sir William Rowan Hamilton in 1843 and applied to mechanics in three-dimensional space. At first, quaternions were regarded as pathological, because they disobeyed the commutative law ab = ba. Although they have been superseded in most applications by vectors, they still find uses in both theoretical and applied mathematics, in particular for calculations involving three-dimensional rotations. James Clerk Maxwell first published his famous theory describing electricity and magnetism as a set of twenty equations, but he was later able to reformulate it as four equations using quaternions. Heaviside translated these into four vector equations, the form typically taught in basic physics classes today. Heaviside's vector version is compatible with Einstein's special relativity, but the quaternion form is not; 131; 156; "Quaternion-ray weapons" 445; 511; 525; Wars, 526, 548; 533-34; 538-39; Quaternionic Weapon, 542; 557; 564; 590; Wikipedia entry; Quaternions at MathWorld; Hamiltonian quaternions at PlanetMath; Finding the site of Hamilton's inspiration (by mathematical physicist John Baez); Conspiracy-theory takes on mathematical history [1] [2] (by Tom Bearden, promotor of a dubious free energy machine)
