Guesswork Quotes
My great-grandfather Melvin had been a carpenter - so was my father - and they taught me the value of tools: saws, hammers, chisels, files and rulers. It all dealt with conciseness and precision. It eliminated guesswork. One has to know his tools, so he doesn't work against himself.

Mathematics is not a deductive science - that's a cliché. When you try to prove a theorem, you don't just list the hypotheses, and then start to reason. What you do is trial and error, experimentation, guesswork. You want to find out what the facts are, and what you do is in that respect similar to what a laboratory technician does. Possibly philosophers would look on us mathematicians the same way as we look on the technicians, if they dared.
