== "Beautiful, but not robust" Quote ==
The beginning of this article provides a quote from Steven Weinberg on quantum field theory saying that QFT is "beautiful, but not robust." The way the quote is given here makes it sound like this comment was intended as a criticism of QFT. I looked up the source of the quote, and it appears (to me at least) that the quote was not meant as a criticism at all. I think what Weinberg was saying is that QFT has to satisfy a lot of strong properties, such as gauge invariance and renormalizeablility. It is in that sense that QFT is not robust. But the point I think Weinberg is making is that this gives us hope for finding a grand unified theory, since we don't have much wiggle room in the kinds of theories we can propose.
Given that, I propose the quote be removed, since its likely meaning is out of context with the way the quote is being used. --[[User:Lemonpeel|Lemonpeel]] 12:00, 15 June 2009 (EDT)
