Mr. Levy returned to the Linda Hall Library last week to discuss the upcoming total solar eclipse on August 21, 2017, which will cut a path across the United States from the Pacific northwest to South Carolina.
While the talk was open to the public, I was not able to attend. Happily, the Linda Hall Library live streamed his talk. It is currently archived at livestream.com. Unfortunately, the video is glitchy, the audio is fine and definitely worth a listen. Dial it up and let it play in the background!
