  • 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

Famous quotes containing the words science and/or engineering:

    Already nature is serving all those uses which science slowly derives on a much higher and grander scale to him that will be served by her. When the sunshine falls on the path of the poet, he enjoys all those pure benefits and pleasures which the arts slowly and partially realize from age to age. The winds which fan his cheek waft him the sum of that profit and happiness which their lagging inventions supply.
    Henry David Thoreau (1817–1862)

    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)
