High Pressure

High pressure in science and engineering is studying the effects of high pressure on materials and the design and construction of devices, such as a diamond anvil cell, which can create high pressure. By high pressure it is usually meant pressures of thousands (kilobars) or millions (megabars) of times atmospheric pressure (about 1 bar or 100,000 Pa).

Famous quotes containing the words pressure and/or high:

    The mother whose self-image is dependent on her children places on those children the responsibility for her own identity, and her involvement in the details of their lives can put great pressure on the children. A child suffers when everything he or she does is extremely important to a parent; this kind of over-involvement can turn even a small problem into a crisis.
    Grace Baruch (20th century)

    When you’re right in the market, it’s the best high you can imagine. It’s a high without any alcohol. When you’re wrong, it’s the lowest low you can imagine.
    Michelle Miller (b. c. 1950)
