If they don't depend on true evidence, scientists are no better than gossips. The effort to understand the universe is one of the very few things that lifts human life a little above the level of farce, and gives it some of the grace of tragedy. No science is immune to the infection of politics and the corruption of power. Dissent is the native activity of the scientist, and it has got him into a good deal of trouble in the last years. All science requires mathematics.
Science is a wonderful thing.
One gets such wholesale returns of conjecture from such a trifling investment in fact. Mark Twain Overhead 2.
