| gravity | Origin: L. Gravitas, fr. Gravis heavy; cf. F. Gravite. See Grave, Grief. 1. The state of having weight; beaviness; as, the gravity of lead. 2. Sobriety of character or demeanor. "Men of gravity and learning."< p. 648 needs proofing ##proof - especially italicized words (aso in etymologies) are not properly marked 3. Importance, significance, dignity, etc; hence, seriousness; enormity; as, the gravity of an offense. "They derive an importance from . . . The gravity of the place where they were uttered." (Burke) 4. <physics> The tendency of a mass of matter toward a center of attraction; especially, the tendency of a body toward the center of the earth; terrestrial gravitation. 5. Lowness of tone; opposed to acuteness. Center of gravity See Center. Gravity battery, See Battery. Specific gravity, the ratio of the weight of a body to the weight of an equal volume of some other body taken as the standard or unit. This standard is usually water for solids and liquids, and air for gases. Thus, 19, the specific gravity of gold, expresses the fact that, bulk for bulk, gold is nineteen times as heavy as water.

| gravity, altered | A change in, or manipulation of, gravitational force. This may be a natural or artificial effect. (12 Dec 1998) |
| gravity perception | Process whereby a bodily structure or organism (animal or plant) receives or detects a gravity stimulus. The sensing may be direct or indirect and may or may not initiate a reaction to the stimulus. (12 Dec 1998) |
| specific gravity | A measure of concentration. It is the weight of a substance, as compared (as a ratio) with that of an equal volume of water. (27 Sep 1997) |
| absolute zero | <chemistry, physics> This is the lowest possible temperature (0 Kelvin, -273.15 degrees Celsius, -459.67 degrees Fahrenheit). at this temperature, all molecular motion stops. (15 Jan 1998) |
| Patient Zero | The individual identified in 1982 by the Centres for Disease Control as responsible for introducing the HIV virus into the U.S. Population. A Canadian citisen, Patient Zero was a homosexual airline steward who claimed to have had as many as 2,500 sexual encounters. CDC epidemiologists located 19 men in Los Angeles, 22 in New York City, and 8 in other cities who had contracted AIDS from contact with Patient Zero, the earliest known cases of the disease in the U.S. Revealed to be Gaetan Dugas, Patient Zero died in 1984 due to AIDS-related illness.

| protein Zero | <protein> The major glycoprotein of peripheral nerve myelin, an integral transmembrane protein, synthesised by Schwann cells (Mw = 28, 500). (18 Nov 1997) |
| zero | Origin: F. Zero, from Ar. Cafrun, cifrun, empty, a cipher. Cf. Cipher. 1. <mathematics> A cipher; nothing; naught. 2. The point from which the graduation of a scale, as of a thermometer, commences. Zero in the Centigrade, or Celsius thermometer, and in the Reaumur thermometer, is at the point at which water congeals. The zero of the Fahrenheit thermometer is fixed at the point at which the mercury stands when immersed in a mixture of snow and common salt. In Wedgwood's pyrometer, the zero corresponds with 1077 deg on the Fahrenheit scale. 3. The lowest point; the point of exhaustion; as, his patience had nearly reached zero. Absolute zero. See Absolute. <physics> Zero method, 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, the point indicating zero, or the commencement of a scale or reckoning. Source: Websters Dictionary (01 Mar 1998) |
| zero degree teeth | Prosthetic teeth having no cusp angles in relation to the horizontal. (05 Mar 2000) |
| zero end-expiratory pressure | Airway pressure which, at the end of expiration, equals atmospheric pressure. (05 Mar 2000) |
| zero energy thermonuclear assembly | <radiobiology> A British fusion device in which scientists observed fusion neutrons in 1958. They were erroneously considered to be thermonuclear (coming from particles with a Maxwellian velocity distribution) and were a cause for the initial optimism that fusion energy would be easy. They were actually due to electromagnetic acceleration during a plasma instability, an effect which cannot be scaled up to produce useful energy. (09 Oct 1997) |
| zero-order reaction | A reaction that proceeds at a particular rate independently of the concentration of the reactant or reactants. (05 Mar 2000) |
| zero time-binding DNA | DNA that has become the duplex form at the start of a reassociation process. Acronym: DNA (05 Mar 2000) |
