Xylene \Xy"lene\, n. [Gr. xy`lon wood.] (Chem.)       Any of a group of three metameric hydrocarbons of the       aromatic series, found in coal and wood tar, and so named       because found in crude wood spirit. They are colorless, oily,       inflammable liquids, {C6H4.(CH3)2}, being dimethyl benzenes,       and are called respectively {orthoxylene}, {metaxylene}, and       {paraxylene}. Called also {xylol}.          Note: Each of these xylenes is the nucleus and prototype of a                distinct series of compounds.

Orthoxylene \Or`tho*xy"lene\, n. [Ortho- + xylene.] (Chem.)       That variety of xylene in which the two methyl groups are in       the ortho position; a colorless, liquid, combustible       hydrocarbon resembling benzene.

From Jargon File (4.2.0, 31 JAN 2000) [jargon]:
orthogonal adj.   [from mathematics] Mutually independent; well    separated; sometimes, irrelevant to.   Used in a generalization of    its mathematical meaning to describe sets of primitives or    capabilities that, like a vector basis in geometry, span the entire    `capability space' of the system and are in some sense    non-overlapping or mutually independent.   For example, in    architectures such as the PDP-11 or VAX where all or nearly all    registers can be used interchangeably in any role with respect to    any instruction, the register set is said to be orthogonal.   Or, in    logic, the set of operators `not' and `or' is orthogonal, but the    set `nand', `or', and `not' is not (because any one of these can be    expressed in terms of the others).   Also used in comments on human    discourse: "This may be orthogonal to the discussion, but...."

ORTHOCARTAN          A system for {symbolic mathematics},       especially General Relativity, written by A. Krasinski of       Warsaw in the early 1980s.          (1995-04-12)
From The Free On-line Dictionary of Computing (15Feb98) [foldoc]:
orthogonal          At 90 degrees (right angles).          N mutually orthogonal {vectors} {span} an N-dimensional       {vector space}, meaning that, any vector in the space can be       expressed as a {linear combination} of the vectors.   This is       true of any set of N {linearly independent} vectors.          The term is used loosely to mean mutually independent or well       separated.   It is used to describe sets of primitives or       capabilities that, like linearly independent vectors in       geometry, span the entire "capability space" and are in some       sense non-overlapping or mutually independent.   For example,       in logic, the set of operators "not" and "or" is described as       orthogonal, but the set "nand", "or", and "not" is not       (because any one of these can be expressed in terms of the       others).          Also used loosely to mean "irrelevant to", e.g. "This may be       orthogonal to the discussion, but ...", similar to "going off       at a tangent".          See also {orthogonal instruction set}.          [{Jargon File}]          (2002-12-02)
From The Free On-line Dictionary of Computing (15Feb98) [foldoc]:
orthogonal instruction set          An {instruction set} where all (or most)       instructions have the same format and all {registers} and       {addressing modes} can be used interchangeably - the choices       of {op code}, register, and addressing mode are mutually       independent (loosely speaking, the choices are       "{orthogonal}").   This contrasts with some early {Intel}       {microprocessors} where only certain registers could be used       by certain instructions.          Examples include the {PDP-11}, {680x0}, {ARM}, {VAX}.          (2002-06-26)
