Banish thoughts of pocket protectors and pencil-necked physiques: These guys, to put it scientifically, are hot. In fact, they're Studmuffins of Science, the subjects of a 1996 pin-up calendar featuring 12 of the country's brightest and beefiest Ph.D.s. Posing as "Dr. December" is Chicago astrophysicist Edward "Rocky" Kolb, who, alongside a thumbnail summary of his work, offers admirers some never-before-revealed personal data ("I was the fifth Beatle."). The fun, says calendar creator Karen Hopkin, has a serious point: to show scientists as regular folks. With awesome pecs.

Dr. December 1996

Professor of Astronomy and Astrophysics
The University of Chicago
Member and Former Director of Theoretical Astrophysics Group
Fermi National Accelerator Laboratory Batavia, Illinois

Celebrity impression: Elvis during his last minutes. "It involves lots of peanut butter," says Rocky. "It's not a pretty sight."

Best part about being a scientist: It shuts up those irritating, chatty people on airplanes. "Tell someone you're a theoretical astrophysicist and they quickly turn their attentions back to the in-flight magazines."

Favorite candidate for dark matter: The light photino (Remember, you heard it here, first).

Best blackboards: At Fermilab, every office has at least one that stretches from the floor to the ceiling.

Favorite elements: Hydrogen and helium. "They make up 99 percent of the universe," he says.

Biggest secret: He was the fifth Beatle.
