Hawking: Women are 'complete mystery'

LONDON, Jan. 6 (UPI) -- Renowned British physicist Stephen Hawking, who turns 70 Sunday, says some things remain a mystery to him -- especially women.

The wheelchair-bound Hawking, director of research at the Institute for Theoretical Cosmology at Cambridge, was diagnosed with motor neurone disease in 1963 but went on to become Lucasian professor of mathematics at Cambridge, a chair he held for 30 years that was once occupied by Isaac Newton.

In an interview with New Scientist magazine, Hawking, who is known for his contributions to the fields of cosmology and quantum gravity, especially in the context of black holes, was asked what he thinks about most during the day.

"Women," he responded. "They are a complete mystery."
