But this is very impopular, changing minds.When the facts change, I change my mind. What do you do, sir?

I learned to distrust all physical concepts as the basis for a theory. Instead one should put one's trust in a mathematical scheme, even if the scheme does not appear at first sight to be connected with physics. One should concentrate on getting interesting mathematics.
It seems that Einstein was expressing a similar sentiment. What I find funny is that this idea is beyond the comprehension of this forum, since the majority opinion on string theory around here seems to be quite skeptical, even though the majority opinion of professional theorists is that string theory is is a correct description of physics beyond the standard model.This result is too beautiful to be false; it is more important to have beauty in one's equations than to have them fit experiment.
"Did Einsten Really Say It? By BARBARA WOLFFAlso Einstein has never been identified as the author of If the facts don't fit the theory, change the facts, here, too, due to the inherent assertion, one cannot help having severe doubts. Therefore a quotation as inconsistent with Einstein’s real attitude as the one under discussion, should not be treated as an authentic statement
I wish she had discussed this one as it is apparently controversial.This article examines 13 of some of the most popular quotes assigned to Einstein"
George Gamow, My World Line, 1970George Gamow said:Much later, when I was discussing cosmological problems with Einstein, he remarked that the introduction of the cosmological term was the biggest blunder of his life.
