I couldn't find a discussion about nerd songs, so I guess this is the first one.
My friend is into pi (3.14159265...) and she learned this song by heart: http://www.youtube.com/watch?v=VqpWETqoD5Q
I thought that was pretty cool, so I searched for more songs like that and found the element song and the DNA replication song (you really should youtube it xD)... and I adore them! So, yeah, my question is if anybody knows more 'nerd' songs and wants to share it with me/other nerdfighters. :)
