Famous quotes containing the words world, record and/or progression:

    Is it possible, after all, that spite of bricks and shaven faces, this world we live in is brimmed with wonders, and I and all mankind, beneath our garbs of common-placeness, conceal enigmas that the stars themselves, and perhaps the highest seraphim can not resolve?
    Herman Melville (1819–1891)

    Bob freed your mind the way Elvis freed your body. He showed us that just because music was innately physical did not mean that it was anti-intellectual. He had the vision and the talent to make a pop record that contained the whole world.
    Bruce Springsteen (b. 1949)

    Measured by any standard known to science—by horse-power, calories, volts, mass in any shape,—the tension and vibration and volume and so-called progression of society were full a thousand times greater in 1900 than in 1800;Mthe force had doubled ten times over, and the speed, when measured by electrical standards as in telegraphy, approached infinity, and had annihilated both space and time. No law of material movement applied to it.
    Henry Brooks Adams (1838–1918)
