This... from Richard Feynman...

"I would rather have questions that can't be answered, than answers that can't be questioned."

"If you thought that science was certain, well that's an error on your part."

"The highest form of understanding that we can achieve is laughter, and human compassion."

"The imagination of nature is far greater than the imagination of man."

  As for me,  I find scientists to be a joy for in celebrating mystery there is neither fear nor anger. 

Peace and all good
