Well, that cheers me up.

Steven F. Weinberg won the 1979 Nobel Prize in physics for linking two of the fundamental forces (EM and the weak force), and thus bringing us that much closer to a grand unified theory of everything.

In her book The Canon, Natalie Angier reports that Weinberg "recently switched from particle physics to cosmology because the math in particle physics was getting beyond him."

I find this to be very, very heartening.
