Famous quotes containing the words science and/or technology:
“The great pagan world of which Egypt and Greece were the last living terms ... once had a vast and perhaps perfect science of its own, a science in terms of life. In our era this science crumbled into magic and charlatanry. But even wisdom crumbles.”
—D.H. (David Herbert)
“One can prove or refute anything at all with words. Soon people will perfect language technology to such an extent that they’ll be proving with mathematical precision that twice two is seven.”
—Anton Pavlovich Chekhov (1860–1904)
