This frightening picture depcits the relative strengths of various nuclear weapons that have been detonated. Click the picture for a full-size version. Note that you can barely even see the Hiroshima bomb without the inset picture.

Thanks to my white and nerdy friend George Alexander for pointing me to my new favorite YouTube video. Weird Al Yankovic's White and Nerdy vieo. This video actually mentions "vector calculus" in the lyrics, has the Schrodinger equation for the hydrogen atom (almost - the h needs a bar) in the background of a few frames, and it mentions Kirk vs. Picard. Awesome.
