1 Back in 1994, at the University of Texas at Austin, Peter H. Dana wrote an overview of the global positioning system (GPS). You can read this online, courtesy of the Geographer's Craft Project at the University of Colorado at Boulder, and it is an excellent first stop if you want to know more about GPS and how it works. Unlike other GPS tutorials, this has a ton of lovely technical information to help you understand the topic.

2 How many of you are familiar with podcasts? These are Web feeds of audio or video files available on the Internet for you to download or subscribe to. There are many, many podcasts out there, covering quite the range of topics. I'm just going to highlight one of them here, called This Week in Science. The hour-long radio show out of U.C. Davis (also available in podcast form) includes interviews with scientists and discussions of science stories in the news and it's a fun listen.

3 Finally, since Easter is this month, I present to you PeepHenge, in which Peeps (those colorful and whimsical marshmallow shapes that are so sweet they make my teeth itch) have been carefully assembled into a replica of Stonehenge. Actually, make sure you check out the parent site, as well, to view the Lord of the Rings as enacted by Peeps. Words fail me.
