### Famous quotes containing the word mathematics:

“*Mathematics* alone make us feel the limits of our intelligence. For we can always suppose in the case of an experiment that it is inexplicable because we don’t happen to have all the data. In *mathematics* we have all the data ... and yet we don’t understand. We always come back to the contemplation of our human wretchedness. What force is in relation to our will, the impenetrable opacity of *mathematics* is in relation to our intelligence.”

—Simone Weil (1909–1943)

“It is a monstrous thing to force a child to learn Latin or Greek or *mathematics* on the ground that they are an indispensable gymnastic for the mental powers. It would be monstrous even if it were true.”

—George Bernard Shaw (1856–1950)
