There aren't many songs with a scientist as the main character, but Coldplay's "The Scientist" is one of their biggest hits. The guy in the song is brilliant, but despondent because he's lost his girl after neglecting her for his work.
Who writes a song about a name they found in a phone book? That's just one of the everyday things these guys find to sing about. Anything in their field of vision or general scope of knowledge is fair game. If you cross paths with them, so are you.
