quote for the day

"Science, particularly mathematics, though it seems less practical and less real than the news contained contained in the latest radio dispatches, appears to be building the one permanent and stable edifice in an age where all others are either crumbling or being blown to bits.  This is not to say that science has not also undergone revolutionary changes. But it has happened quietly and honorably. That which is no  longer useful has been rejected only after mature deliberation, and the building has been reared steadily on the creative achievements of the past." - Edward Kasner and James R. Newman
