I think I would like to start a new type of post for Fridays: a collection of fun links. Shoot me a message if you have any suggestions.

To start with, try these:

• Make your own scanning electron microscope. Student project, anyone?
• How to turn raw images from the Hubble Space telescope into the beautiful pictures you see on the internet, demonstrated in two minutes. (via Phil Plait)
• A map of average penis sizes by country, and a map of nuclear weapons distribution. (via John Rennie on Twitter) I don’t think further commentary is necessary.
• xkcd explains why scientists don’t actually take the wonder and beauty out of the universe.

I’ve already shared some of this stuff on Twitter (you’re following me, right?), but it never hurts to share good stuff twice!
