Acid (n.) 【化】酸 [C] [U]；有酸味的東西 [U]；尖刻，譏刺 [U] A sour substance.

Acid (n.) (Chem.) One of a class of compounds, generally but not always distinguished by their sour taste, solubility in water, and reddening of vegetable blue or violet colors. They are also characterized by the power of destroying the distinctive properties of alkalies or bases, combining with them to form salts, at the same time losing their own peculiar properties. They all contain hydrogen, united with a more negative element or radical, either alone, or more generally with oxygen, and take their names from this negative element or radical. Those which contain no oxygen are sometimes called hydracids in distinction from the others which are called {oxygen acids} or {oxacids.}

Note: In certain cases, sulphur, selenium, or tellurium may take the place of oxygen, and the corresponding compounds are called respectively {sulphur acids} or {sulphacids}, {selenium acids}, or {tellurium acids}. When the hydrogen of an acid is replaced by a positive element or radical, a salt is formed, and hence acids are sometimes named as salts of hydrogen; as hydrogen nitrate for nitric acid, hydrogen sulphate for sulphuric acid, etc. In the old chemistry the name acid was applied to the oxides of the negative or nonmetallic elements, now sometimes called anhydrides.

Acid (a.) Harsh or corrosive in tone; "an acerbic tone piercing otherwise flowery prose"; "a barrage of acid comments"; "her acrid remarks make her many enemies"; "bitter words"; "blistering criticism"; "caustic jokes about political assassination, talk-show hosts and medical ethics"; "a sulfurous denunciation"; "a vitriolic critique" [syn: {acerb}, {acerbic}, {acid}, {acrid}, {bitter}, {blistering}, {caustic}, {sulfurous}, {sulphurous}, {virulent}, {vitriolic}].

ACME, () A Company that Makes Everything (slang)

Acme (n.) [from Greek akme highest point of perfection or achievement] The canonical supplier of bizarre, elaborate, and non-functional gadgetry ? where Rube Goldberg and Heath Robinson (two cartoonists who specialized in elaborate contraptions) shop. The name has been humorously expanded as A (or American) Company Making Everything. (In fact, Acme was a real brand sold from Sears Roebuck catalogs in the early 1900s.) Describing some X as an ? Acme X? either means ?This is insanely great?, or, more likely, ?This looks insanely great on paper, but in practice it's really easy to shoot yourself in the foot with it.? Compare pistol.

This term, specially cherished by American hackers and explained here for the benefit of our overseas brethren, comes from the Warner Brothers' series of ?Road-runner? cartoons. In these cartoons, the famished Wile E. Coyote was forever attempting to catch up with, trap, and eat the Road-runner. His attempts usually involved one or more high-technology Rube Goldberg devices ? rocket jetpacks, catapults, magnetic traps, high-powered slingshots, etc. These were usually delivered in large wooden crates labeled prominently with the Acme name ? which, probably not by coincidence, was the trade name of a peg bar system for superimposing animation cels used by cartoonists since forever. Acme devices invariably malfunctioned in improbable and violent ways.

ACME, () A Company that Makes Everything.

The canonical imaginary business. Possibly also derived from the word "acme" meaning "highest point".
