Famous quotes containing the words physical and/or design:

    I was always a feminist, for I liked intellectual revolt as much as I disliked physical violence. On the whole, I think women have lost something precious, but have gained, immeasurably, by the passing of the old order.
    Ellen Glasgow (1873–1945)

    A good scientist is a person with original ideas. A good engineer is a person who makes a design that works with as few original ideas as possible. There are no prima donnas in engineering.
    Freeman Dyson (b. 1923)
