...this sounds like a physicist making a bad joke....
Well, as someone who actually has a physics degree, I'll let you in on the secret: physicists tend to at least half-believe themselves when they make this joke. There is (or at least was a couple of decades ago) a feeling that physics is a real man's science, while people who just can't handle the intellectual rigor go into fields like biology and sociology. This is (or was) especially true for those in fields like particle physics -- you would be astounded by the level of arrogance in those fields. I was always surprised that those people can fit their heads through ordinary doorways.
