Just some quick reminders of things that may interest y'all:
The Celestron Capture the Universe contest is still going strong! This is an astrophotography contest sponsored by Celestron and Discover Magazine. The rules and all that are at that link, but I might suggest that the comet Hartley 2, currently in the far north, is making an excellent target of itself for the next few days. The contest ends on Friday, October 30, so hurry!
The Donors Choose fundraiser is also still going on. So far, my generous readers have donated well over $2000 to help students learn math and science! I am really, really proud of all of you, and extremely grateful for helping this tremendous effort. You've made a lot of teachers and kids across America really happy.
Don't forget to take a look at the best physical science websites up for the Physics.org awards! I'm judging the Best Q&A sites, and I'm looking forward to poring over them, though not so much looking forward to choosing my favorite. That'll be tough... and you can help, since every category has a People's Choice award, too!
