Addition Operation

Famous quotes containing the words addition and/or operation:

    Depend upon it there comes a time when for every addition of knowledge you forget something that you knew before. It is of the highest importance, therefore, not to have useless facts elbowing out the useful ones.
    Sir Arthur Conan Doyle (1859–1930)

    You may read any quantity of books, and you may almost as ignorant as you were at starting, if you don’t have, at the back of your minds, the change for words in definite images which can only be acquired through the operation of your observing faculties on the phenomena of nature.
    Thomas Henry Huxley (1825–95)
