Famous quotes containing the words physical, chemical and/or solutions:

    “The author’s conviction on this day of New Year is that music begins to atrophy when it departs too far from the dance; that poetry begins to atrophy when it gets too far from music; but this must not be taken as implying that all good music is dance music or all poetry lyric. Bach and Mozart are never too far from physical movement.”
    —Ezra Pound (1885–1972)

    “If Thought is capable of being classed with Electricity, or Will with chemical affinity, as a mode of motion, it seems necessary to fall at once under the second law of thermodynamics as one of the energies which most easily degrades itself, and, if not carefully guarded, returns bodily to the cheaper form called Heat. Of all possible theories, this is likely to prove the most fatal to Professors of History.”
    —Henry Brooks Adams (1838–1918)

    “Science fiction writers foresee the inevitable, and although problems and catastrophes may be inevitable, solutions are not.”
    —Isaac Asimov (1920–1992)
