Quote for the day: Richard Feynman on the value of knowledge

"It is only the principle of what you think will happen in a case you have not tried that is worth knowing about. Knowledge is of no real value if all you can tell me is what happened yesterday. It is necessary to tell what will happen tomorrow if you do something--not only necessary, but fun. Only you must be willing to stick your neck out." ~~ Richard Feynman, The Meaning of It All: Thoughts of a Citizen-Scientist
