Lots of rockers and actors have had asteroids named in their honor, but Brian May is no doubt the only true scientist of the bunch. The brainy guitarist/astrophysicist best known for his work with Queen turns 67 today. I could always recognize his distinctive style. He used his custom-built "Red Special" guitar to produce sounds that mimicked all kinds of instruments, such as trombones and piccolos. In 2012, readers of Guitar World magazine voted him the 2nd greatest guitarist of all time, and Rolling Stone pegged him at #26 in their list of Top 100 guitarists.
