Happy Birthday, Stephen Hawking

Summary: 
On Professor Hawking’s 71st birthday, we’d like to share a never-before-seen video from his visit to the White House.

On August 12th, 2009, President Obama awarded the Medal of Freedom, America’s highest civilian honor, to Stephen Hawking. “From his wheelchair he's led us on a journey to the farthest and strangest reaches of the cosmos,” said the President, “In so doing, he has stirred our imagination and shown us the power of the human spirit here on Earth.”

Today, on Professor Hawking’s 71st birthday, we’d like to share a never-before-seen video from his visit. Honored as an "agent of change," Hawking discusses the thrill of discovery and overcoming the challenge of ALS, also known as Lou Gehrig's disease.
