Pressure Gradient Force

Famous quotes containing the words pressure and/or force:

“Under the pressure of the cares and sorrows of our mortal condition, men have at all times, and in all countries, called in some physical aid to their moral consolations—wine, beer, opium, brandy, or tobacco.”
—Edmund Burke (1729–1797)

“Nations do not think, they only feel. They get their feelings at second hand through their temperaments, not their brains. A nation can be brought—by force of circumstances, not argument—to reconcile itself to any kind of government or religion that can be devised; in time it will fit itself to the required conditions; later it will prefer them and will fiercely fight for them.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
