Fixed Focal Length

Famous quotes containing the words fixed and/or length:

    To find the length of an object, we have to perform certain
    physical operations. The concept of length is therefore fixed when the operations by which length is measured are fixed: that is, the concept of length involves as much as and nothing more than the set of operations by which length is determined.
    Percy W. Bridgman (1882–1961)

    Whoever aims publicly at great things and at length perceives secretly that he is too weak to achieve them, has usually also insufficient strength to renounce his aims publicly, and then inevitably becomes a hypocrite.
    Friedrich Nietzsche (1844–1900)
