This is What's Trending Today...

Many universities this week are marking "Open Access Week." The yearly event centers on improving the online availability of academic research to the public.

Cambridge University in England celebrated by releasing the 1966 doctoral thesis of Stephen Hawking for free online. Hawking was a graduate student at Cambridge from 1962 to 1966.

Hawking is the world's best-known physicist. He completed his thesis, "Properties of Expanding Universes," when he was just 24 years old. The work explores ideas about the origins of the universe -- ideas that Hawking has studied throughout his career.

News of Hawking's publicly available thesis spread quickly. Within hours, Cambridge's website collapsed because of the high number of people trying to access Hawking's research paper.

A Cambridge spokesman said in a statement, "We have had a huge response to Professor Hawking's decision to make his PhD thesis publicly available to download, with almost 60,000 downloads in less than 24 hours." The spokesman said that, as a result of the popularity, the website may perform slowly at times.

Hawking's research was already the most-requested item in Cambridge's library. He recently gave the university permission to make it an "Open Access" document.

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

Hawking's newly available thesis -- and talk of how it shut down Cambridge's website -- became trending topics on Twitter and Facebook.

Many on social media said they were pleased that so many people around the world are interested in reading Hawking's research.

Others wrote that they "loved" that Hawking is the famous person "breaking the internet" this week.

And that's What's Trending Today...
