"The mere formulation of a problem is often far more essential than it's solution, which may be merely a matter of mathematical or experimental skill. To raise a new question, new possibilities, to regard old problems from a new angle requires creative imagination and marks the real advances in science."
--- Albert Einstein
Nobel Prize in Physics, 1921
"What makes science grow is new ideas, including false ideas."
--- Sir Karl Popper
"Every great scientific truth goes through three stages. First, people will say it conflicts with the bible. Next, they will say it had been discovered before. Lastly, they say they always believed it."
--- Louis Agassiz
1807 - 1873
