In Science and Engineering
- Void (astronomy), the empty spaces between galaxy filaments
- Lack of matter, or vacuum
- Void, in boiling heat transfer, formed where there is a departure from nucleate boiling, causing a critical heat flux
- Void, in mechanical engineering, is a bubble or pocket of vapor which forms near a propeller or pump, causing cavitation
- Void, in casting or injection molding, describes a defect where there are empty spaces (air pockets) in a completed part
- Void coefficient, in nuclear engineering, is a measure of how spaces devoid of either moderator or coolant affect the reactivity of a nuclear reactor
- Void ratio, of voids to solids in a mixture, in material sciences
- Void safety, an issue raised in programming by a reference that is not attached to an object, also known as null reference
- Void type, keyword indicating the absence of type information in many programming languages
- VoiD (Vocabulary of Interlinked Dataset), the vocabulary to describe linked open datasets in order for users to discover, interlink and evaluate the quality of these datasets on the Web

Famous quotes containing the words science and/or engineering:
“It is clear that everybody interested in science must be interested in world 3 objects. A physical scientist, to start with, may be interested mainly in world 1 objects—say crystals and X-rays. But very soon he must realize how much depends on our interpretation of the facts, that is, on our theories, and so on world 3 objects. Similarly, a historian of science, or a philosopher interested in science must be largely a student of world 3 objects.”
—Karl Popper (1902–1994)
“Mining today is an affair of mathematics, of finance, of the latest in engineering skill. Cautious men behind polished desks in San Francisco figure out in advance the amount of metal to a cubic yard, the number of yards washed a day, the cost of each operation. They have no need of grubstakes.”
—Merle Colby, U.S. public relief program (1935-1943)
