Stephen Hawking’s Ph.D thesis goes online, website crashes

LONDON -- Cambridge University has put Stephen Hawking's doctoral thesis online, triggering so much interest that it crashed the university's website.

Completed in 1966 when Hawking was 24, "Properties of Expanding Universes" explores ideas about the origins of the universe that have resonated through the scientist's career.

"This thesis has been made openly available with the kind permission of Professor Stephen Hawking," the university website reads.

The university says the thesis was already the most-requested item in its online repository. 

It was free to download Monday to mark Open Access Week. The website was intermittently inaccessible during the day as it struggled to handle to the huge amount of interest.

Hawking said he hoped making his thesis available to all would "inspire people around the world to look up at the stars and not down at their feet; to wonder about our place in the universe and to try and make sense of the cosmos."

Hawking, who is now 75, was first diagnosed at age 21 with a form of amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, that has gradually left him paralyzed. At the time, he wasn't expected to live more than a few years. Instead, he went on to have one of the most renowned careers in modern science.
