Scientific observation

I think it is very important--at least it was to me--that if you are going to teach people to make observations, you should show that something wonderful can come from them. I learned then what science was about: it was patience. If you looked, and you watched, and you paid attention, you got a great reward from it--although possibly not every time. As a result, when I became a more mature man, I would painstakingly, hour after hour, for years, work on problems--sometimes many years, sometimes shorter times; many of them failing, lots of stuff going into the wastebasket--but every once in a while there was the gold of a new understanding that I had learned to expect when I was a kid, the result of observation. For I did not learn that observation was not worthwhile. - Richard Feynmann [1]
