Richard Feynman Lecture — “Los Alamos From Below”

There are quite a few copies of this Feynman lecture floating around out there, but most end prior to the question from the audience.

After the lecture, a guy in the audience asks Feynman about his safe-cracking stories and Feynman goes on for about another ten minutes relating three different stories on his safe-cracking while at Los Alamos National Laboratories. Enjoy!

Rubin Observatory peers into the ‘hidden universe’ and discovers stream of stars longer than our entire Milky Way

“We are expecting that when Rubin obtains very deep imaging of galaxies, we will see them surrounded by a faint network of stellar streams,” Romanowsky concluded. “The discovery of the stream shows the excellent characteristics of Rubin for making such observations, and points to a rich future of similar discoveries as vast areas of the sky are mapped out.”

The team’s research is available on the paper repository site arXiv.
