Galileo's Pendulum

Saturn's largest moon Titan, with Saturn's rings as the backdrop.

With the site redesign yesterday, I didn’t post a link roundup, so here are a few (non-neutrino-related) I’ve collected over the last couple of days:

• NASA sounds, downloadable as ringtones for your phone!
• What happens when you drop a Slinky? The setup and the answer.
• Increased solar activity, including a coronal mass ejection (CME), means that there is a lot of auroral activity. In fact, many people got a chance to see the Northern Lights for the first time last night!
• Animal-related insults like “pig” and “dog” show a distinct lack of imagination, when there are so many species names that make for great insults (and those are just vertebrates).
