Neutral Buoyancy

Neutral buoyancy is a condition in which a physical body's density is equal to the density of the fluid in which it is immersed. This offsets the force of gravity that would otherwise cause the object to sink. An object that has neutral buoyancy will neither sink nor rise.

In scuba diving, the ability to maintain neutral buoyancy through controlled breathing is an important skill.

Famous quotes containing the words buoyancy and/or neutral:

    She keeps
    The Topic over intellectual deeps
    In buoyancy afloat. They see no ghost.
    With sparkling surface-eyes we ply the ball:
    It is in truth a most contagious game:
    Hiding the Skeleton, shall be its name.
    George Meredith (1828–1909)

    I feel the carousel starting slowly
    And going faster and faster: desk, papers, books,
    Photographs of friends, the window and the trees
    Merging in one neutral band that surrounds
    Me on all sides, everywhere I look.
    John Ashbery (b. 1927)
