Stephen Hawking's Doctoral Thesis Crashes Website

Cambridge University has put Stephen Hawking's doctoral thesis online, triggering such interest that it crashed the university's website, the AP reports. 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.

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 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."
