| weight | 1. The quality of being heavy; that property of bodies by which they tend toward the center of the earth; the effect of gravitative force, especially when expressed in certain units or standards, as pounds, grams, etc. Weight differs from gravity in being the effect of gravity, or the downward pressure of a body under the influence of gravity; hence, it constitutes a measure of the force of gravity, and being the resultant of all the forces exerted by gravity upon the different particles of the body, it is proportional to the quantity of matter in the body. 2. The quantity of heaviness; comparative tendency to the center of the earth; the quantity of matter as estimated by the balance, or expressed numerically with reference to some standard unit; as, a mass of stone having the weight of five hundred pounds. "For sorrow, like a heavy-hanging bell, once set on ringing, with his own weight goes." (Shak) 3. Hence, pressure; burden; as, the weight of care or business. "The weight of this said time." "For the public all this weight he bears." (Milton) "[He] who singly bore the world's sad weight." (Keble) 4. Importance; power; influence; efficacy; consequence; moment; impressiveness; as, a consideration of vast weight. "In such a point of weight, so near mine honor." (Shak) 5. A scale, or graduated standard, of heaviness; a mode of estimating weight; as, avoirdupois weight; troy weight; apothecaries' weight. 6. A ponderous mass; something heavy; as, a clock weight; a paper weight. "A man leapeth better with weights in his hands." (Bacon) 7. A definite mass of iron, lead, brass, or other metal, to be used for ascertaining the weight of other bodies; as, an ounce weight. 8. <mechanics> The resistance against which a machine acts, as opposed to the power which moves it. <chemistry> See Atomic, and cf. Element. Dead weight, Feather weight, Heavy weight, Light weight, etc. See Dead, Feather, etc. <astronomy> Weight of observation, a number expressing the most probable relative value of each observation in determining the result of a series of observations of the same kind. Synonym: Ponderousness, gravity, heaviness, pressure, burden, load, importance, power, influence, efficacy, consequence, moment, impressiveness. Origin: OE. Weght, wight, AS. Gewiht; akin to D. Gewigt, G. Gewicht, Icel. Vaett, Sw. Vigt, Dan. Vaegt. See Weigh. 1. To load with a weight or weights; to load down; to make heavy; to attach weights to; as, to weight a horse or a jockey at a race; to weight a whip handle. "The arrows of satire, . . . Weighted with sense." (Coleridge) 2. <astronomy> To assign a weight to; to express by a number the probable accuracy of, as an observation. See Weight of observations, under Weight.

| weight gain | Increase in body weight over existing weight. (12 Dec 1998) |
| weight lifting | A sport in which weights are lifted competitively or as an exercise. (12 Dec 1998) |
| weight loss | Decrease in existing body weight. (12 Dec 1998) |
| weight perception | Recognition and discrimination of the heaviness of a lifted object. (12 Dec 1998) |
| weight sense | The faculty of discriminating various degrees of pressure on the surface. Synonym: baresthesia, piesesthesia, weight sense. (05 Mar 2000) |
| weight-bearing | The physical state of supporting an applied load. This often refers to the weight-bearing bones or joints that support the body's weight, especially those in the spine, hip, knee, and foot. (12 Dec 1998) |
| weightlessness | Condition in which no acceleration, whether due to gravity or any other force, can be detected by an observer within a system. It also means the absence of weight or the absence of the force of gravity acting on a body. Microgravity, gravitational force between 0 and 10 -6 g, is included here. (12 Dec 1998) |
| weightlessness countermeasures | Techniques and routines designed to prevent or reverse unwanted effects of weightlessness experienced during actual and simulated space flight, including physiologic changes related to removal of gravitational loading. Specific measures include creation of artificial gravity, exercise, low-level lower body negative pressure, and use of anti-deconditioning devices. (12 Dec 1998) |
| weightlessness simulation | Condition under normal earth gravity where the force of gravity itself is not actually altered but its influence or effect may be modified and studied. (12 Dec 1998) |
| weights and measures | A unit or standard of measurement. (12 Dec 1998) |
| Weil disease | <microbiology> Infections of humans and many animals caused by organisms of the genus Leptospira. (18 Nov 1997) |
| Weil's basal layer | The layer beneath the odontoblasts of the tooth; it contains reticular fibres but few if any cells. Synonym: Weil's basal zone. (05 Mar 2000) |

| weights and measures |
The definition, agreement and practical use of units of weights and measures have played a crucial role in human endeavor from early ages up to this day. Just to underline the importance of agreed units, the NASA Mars Polar Lander in December 1999 crashed on the planet Mars instead of staying in orbit, due to miscommunications about the value of forces: different people used different assumptions about the unit of measure (newton versus pound force). ...

| weld |
Welding is a fabrication process that joins materials, usually metals or thermoplastics, by causing coalescence. This is often done by melting the workpieces and adding a filler material to form a pool of molten material that cools to become a strong joint, but sometimes pressure is used in conjunction with heat, or by itself, to produce the weld. ...
