Sine Wave Inverters

Famous quotes containing the words sine and/or wave:

    “Faultless honesty is a sine qua non of business life. Not alone the honesty according to the moral code and the Bible. When I speak of honesty I refer to the small, hidden, evasive meannesses of our natures. I speak of the honesty of ourselves to ourselves.”
    —Alice Foote MacDougall (1867–1945)

    “Through the dark cold and the empty desolation,
    The wave cry, the wind cry, the vast waters
    Of the petrel and the porpoise. In my end is my beginning.”
    —T.S. (Thomas Stearns)
