Famous quotes containing the words formula and/or chemical:

    I cannot give you the formula for success, but I can give you the formula for failure—which is: Try to please everybody.
    Herbert B. Swope (1882–1958)

    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)
