"The regularity with which we conclude that further advances in a particular field are impossible seems equaled only by the regularity with which events prove that we are of too limited vision. And it always seems to be those who have the fullest opportunity to know who are the most limited in view. What, then, is the trouble? I think that one answer should be: we do not realize sufficiently that the unknown is absolutely infinite, and that new knowledge is always being produced."

Sarcastic Science, she would like to know, In her complacent ministry of fear, How we propose to get away from here When she has made things so we have to go Or be wiped out. Will she be asked to show Us how by rocket we may hope to steer To some star off there, say, a half light-year Through temperature of absolute zero? Why wait for Science to supply the how When any amateur can tell it now? The way to go away should be the same As fifty million years ago we came- If anyone remembers how that was I have a theory, but it hardly does.
