Because No One Can Get Enough Britney

Right now, I have enough time to do something, but not enough to do something useful. So I'm going to point you to the Britney Spears' Guide to Semiconductor Physics. I am not making this up.

You must read the Introduction, which has a fascinating bit about Heddy Lamarr and frequency hopping. Also, check out the wallpapers. My favorite is the one at the very bottom, but you probably have to be a bit of a physics geek to really appreciate it.
