Richard Feynman, "The Uncertainty of Science"
"Scientists, therefore, are used to dealing with doubt and uncertainty. All scientific knowledge is uncertain. This experience with doubt and uncertainty is important." /1
"Scientists, therefore, are used to dealing with doubt and uncertainty. All scientific knowledge is uncertain. This experience with doubt and uncertainty is important." /1
"I believe that it is of very great value, and one that extends beyond the sciences. I believe that to solve any problem that has never been solved before, you have to leave the door to the unknown ajar." /2
"You have to permit the possibility that you do not have it exactly right. Otherwise, if you have made up your mind already, you might not solve it." /3
"When the scientist tells you he does not know the answer, he is an ignorant man. When he tells you he has a hunch about how it is going to work, he is uncertain about it. " /4
"When he is pretty sure of how it is going to work, and he tells you, "This is the way it's going to work, I'll bet," he still is in some doubt." /5
"And it is of paramount importance, in order to make progress, that we recognize this ignorance and this doubt. Because we have the doubt, we then propose looking in new directions for new ideas." /6
"The rate of the development of science is not the rate at which you make observations alone but, much more important, the rate at which you create new things to test." /7 & Fin
