Caustic \Cau"stic\, n. [L. causticum (sc. medicamentum). See Caustic, a.]
Any substance or means which, applied to animal or other organic tissue, burns, corrodes, or destroys it by chemical action; an escharotic.
(Optics) A caustic curve or caustic surface.
Douglas Harper's Etymology Dictionary
c.1400, "burning, corrosive," from Latin causticus "burning, caustic," from Greek kaustikos "capable of burning; corrosive," from kaustos "combustible; burnt," verbal adjective from kaiein, the Greek word for "to burn" (transitive and intransitive) in all periods, which is of uncertain origin with no certain cognates outside Greek. Figurative sense of "sarcastic" is attested from 1771. As a noun, early 15c., from the adjective.

In differential geometry and geometric optics, a caustic is the envelope of rays either reflected or refracted by a manifold. It is related to the concept of caustics in optics. The ray's source may be a point (called the radiant) or parallel rays from a point at infinity, in which case a direction vector of the rays must be specified.
More generally, especially as applied to symplectic geometry and singularity theory, a caustic is the critical value set of a Lagrangian mapping where is a Lagrangian immersion of a Lagrangian submanifold L into a symplectic manifold M, and is a Lagrangian fibration of the symplectic manifold M. The caustic is a subset of the Lagrangian fibration's base space B.
In optics, a caustic or caustic network is the envelope of light rays reflected or refracted by a curved surface or object, or the projection of that envelope of rays on another surface. The caustic is a curve or surface to which each of the light rays is tangent, defining a boundary of an envelope of rays as a curve of concentrated light. Therefore, in the image to the right, the caustics can be the patches of light or their bright edges. These shapes often have cusp singularities.
Caustic is an American industrial band based out of Madison, WI, created in 2002 by DJ Matt Fanale (AKA Eurotic), who is the sole consistent member. The band's live lineup varies quite a bit, largely depending on the location of the show. Caustic's lyrics are typically humorous, while the music itself ranges between older styled industrial and more modern styled powernoise.
Caustic has performed live at a number of international industrial music festivals, including the 2005 and 2006 Providence Industrial Festival and the 2006 Blacksun, Reverence, Indoctrination, and the UK's Infest Festival in 2007.
