"Science can never explain causes. It describes effects. I can take a book here and drop it. I can't tell you why it fell. I can't explain it. Nobody ever has. I can only describe how it fell."
- Dr. Arno Penzias, Nobel Laureate, on the Dick Cavett Show, 6 January, 1979.

"...is this such a simple law? What about the machinery of it? All we have done is to describe how the earth moves about the sun. But we have not said what makes it go. Newton made no hypothesis about this. He was satisfied to find out what it did witout getting into the machinery of it. No one has since given it any machinery. It is characteristic of the physical laws that they have this abstract character."
- Dr. Richard Feynman, Gravitation, p. 61

"4th D advertised all over the place ya know... All time Best Seller & Academy Award Winner since 1916. Everybody knows this ya know. An so you want to know what it's about so you go to see the movie an' the place is fulla physicists and mathematicians.The seats are all sold out to the Standard Theorists you understand, which reminds you never have. But Einstein and the 4-D space-time continuum is very cool. An air conditioned theater fulla insiders who've long ago grown weary of Dr. Einstein's theory."

"History shows clearly that the advances of science have always been frustrated by the tyrannical influence of certain preconceived notions which were turned into unassailable dogmas. For that reason alone, every serious scientist should periodically make a profound reexaminination of his or her basic principles." - H. Louis De Broglie, New Perspectives in Physics.
