The belief that we can use our aesthetic judgment to ascertain how close a scientific theory is to the truth is deeply held by some of the most notable scientists of our century, including Albert Einstein, P. A. M. Dirac and Steven Weinberg. But does the universe truly conform to the tastes of scientists?
