Some are impressed by quantitative skills. Those of us who were math and physics majors (or in my case, both) are more realistic. Monday's xkcd gives a secret trick in the mouse-over box that pops up that all math and physics majors learn. For those who haven't figured it out, I'm glad that there's a comic strip to reveal the secret.
Also, a few weeks ago, there was a good xkcd about the attitude of some science types towards about interdisciplinary work.
