One of my dear friends loves to chime "Nerd alert!" in the same kind of sing-songy voice that you'd say, "Yoo hoo!" Sometimes I find myself parroting her, blurting out remarks in my best soprano.
This same friend -- a total brainiac Renaissance woman if ever there was one -- happens to love all things food and cooking, and she was gracious enough to share a very cool weblink with me, Cooking For Engineers. I'm as liberal arts as it gets, but this is a really interesting site, full of geekily obsessive information and some really fun recipes that I'm dying to try (check out the one for homemade marshmallows!).
