Famous quotes containing the words physics, electrical and/or engineering:

    “Now the twitching stops. Now you are still. We are through with physiology and theology, physics begins.”
    —Alfred Döblin (1878–1957)

    “Few speeches which have produced an electrical effect on an audience can bear the colourless photography of a printed record.”
    —Archibald Philip Primrose, 5th Earl Rosebery (1847–1929)

    “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.”
