Famous quotes containing the words friction, stir and/or welded:
“We have got onto slippery ice where there is no friction and so in a certain sense the conditions are ideal, but also, just because of that, we are unable to walk. We want to walk so we need friction. Back to the rough ground!”
—Ludwig Wittgenstein (1889–1951)
“Never stir up litigation. A worse man can scarcely be found than one who does this.”
—Abraham Lincoln (1809–1865)
“How marvellous it all is! Built not by saints and angels, but the work of men’s hands; cemented with men’s honest blood and with a world of tears, welded by the best brains of centuries past; not without the taint and reproach incidental to all human work, but constructed on the whole with pure and splendid purpose. Human, and yet not wholly human—for the most heedless and the most cynical must see the finger of the Divine.”
—Archibald Philip Primrose, 5th Earl Rosebery (1847–1929)
