Since I was at the Virginia State Fair yesterday and busy with sundry other things today, I don’t have many links to share today. I did note a preponderance of pseudoscience at the fair, though: “power bands”, vibration-based “weight-loss” systems, and the usual pseudopharmacopia of dietary supplements. I was even accosted by an astroturf organization lobbying in favor of mountaintop-removal mining while pretending to be an environmentalist/sustainable-energy group. I did have a lot of fun (when I wasn’t sighing over the stupidity of our culture) and ate half a basket of fried cheese — which makes up for a great deal, I must say.

• I have been wracked with guilt since my Ada Lovelace Day post on Friday: I have three basic designs in the Galileo’s Pendulum Shop, but none feature women scientists! (After all, I’m the only supplier of science-themed products on the entire Internet. *Ahem.*) Well, I now have two new t-shirt designs featuring Annie Jump Cannon: one for each kissing preference (guy or girl), available in both women’s and men’s sizes. Whoever you like kissing, I have the shirt for you. (I have more information about Cannon and the motto on the shirts here.)
