Famous quotes containing the words video, elementary and/or stream:
“I recently learned something quite interesting about video games. Many young people have developed incredible hand, eye, and brain coordination in playing these games. The air force believes these kids will be our outstanding pilots should they fly our jets.”
—Ronald Reagan (b. 1911)
“Listen. We converse as we live—by repeating, by combining and recombining a few elements over and over again just as nature does when of elementary particles it builds a world.”
—William Gass (b. 1924)
“To me heaven would be a big bull ring with me holding two barrera seats and a trout stream outside that no one else was allowed to fish in and two lovely houses in the town; one where I would have my wife and children and be monogamous and love them truly and well and the other where I would have my nine beautiful mistresses on nine different floors.”
—Ernest Hemingway (1899–1961)
