Zero method
(Physics) a method of comparing, or measuring, forces, electric currents, etc., by so opposing them that the pointer of an indicating apparatus, or the needle of a galvanometer, remains at, or is brought to, zero, as contrasted with methods in which the deflection is observed directly; - called also null method.
Zero point

2.zero - 1. 0, ASCI character 48. Numeric zero, as opposed to the letter "O" (the 15th letter of the English alphabet). In their unmodified forms they look a lot alike, and various kluges invented to make them visually distinct have compounded the confusion.

If your zero is centre-dotted and letter-O is not, or if letter-O looks almost rectangular but zero looks more like an American football stood on end (or the reverse), you're probably looking at a modern character display (though the dotted zero seems to have originated as an option on IBM 3270 controllers). If your zero is slashed but letter-O is not, you're probably looking at an old-style ASCII graphic set descended from the default typewheel on the venerable ASR-33 Teletype (Scandinavians, for whom slashed-O is a letter, curse this arrangement).

If letter-O has a slash across it and the zero does not, your display is tuned for a very old convention used at IBM and a few other early mainframe makers (Scandinavians curse *this* arrangement even more, because it means two of their letters collide). Some Burroughs/Unisys equipment displays a zero with a *reversed* slash. And yet another convention common on early line printers left zero unornamented but added a tail or hook to the letter-O so that it resembled an inverted Q or cursive capital letter-O.
To dream of a seeing zero, signifies absolute freedom and super-consciousness. Zero may be synonymous with the symbol of a circle, which stands for infinity and completeness. It could also warn you that you are going around in circles or that you have nothing. *Please See Also Circle or Number.absolute zero, aught, blank, boiling point, cipher, concentrate on, dew point, duck, dud, dummy, fix on, focus on, freezing point, goose egg, hollow man, home in on, insignificancy, jackstraw, lay figure, man of straw, melting point, nada, nadir, naught, nebbish, nichts, nihil, nix, no such thing, nobody, nonentity, nothing at all, nothing on earth, nothing whatever, nought, null, nullity, pinpoint, puppet, pushover, recalescence point, rock bottom, temperature, thing of naught, trifle, void, whiffet, whippersnapper, zero in on, zilch
