"One of the greatest things about science is it's assumption that what it thinks it knows today will probably be proven wrong tomorrow. The theories of yesterday have served as platforms to climb higher, as Sir Isaac Newton meant when he said, 'If I have been privileged to see farther than others, it's because I stood on the shoulders of giants.'"
~ What The Bleep Do We Know
"Your assumptions are your windows on the world. Scrub them off every once in a while, or the light won't come in."
