Action Physics/euler-lagrange Equations For The Action Integral

Famous quotes containing the words action, physics and/or integral:

    These people who are always briskly doing something and as busy as waltzing mice, they have little, sharp, staccato ideas.... But they have no slow, big ideas. And the fewer consoling, noble, shining, free, jovial, magnanimous ideas that come, the more nervously and desperately they rush and run from office to office and up and downstairs, thinking by action at last to make life have some warmth and meaning.
    Brenda Ueland (1891–1985)

    He who is conversant with the supernal powers will not worship these inferior deities of the wind, waves, tide, and sunshine. But we would not disparage the importance of such calculations as we have described. They are truths in physics because they are true in ethics.
    Henry David Thoreau (1817–1862)

    Self-centeredness is a natural outgrowth of one of the toddler’s major concerns: What is me and what is mine...? This is why most toddlers are incapable of sharing ... to a toddler, what’s his is what he can get his hands on.... When something is taken away from him, he feels as though a piece of him—an integral piece—is being torn from him.
    Lawrence Balter (20th century)
