This two part civics and music piece includes a Q&A session with Carl Sagan from a 1994 interview that  leads into "Symphony of Science - We Are All Connected" by Melody Sheep. From the artist: 

"We Are All Connected" was made from sampling Carl Sagan's Cosmos, The History Channel's Universe series, Richard Feynman's 1983 interviews, Neil deGrasse Tyson's cosmic sermon, and Bill Nye's Eyes of Nye Series, plus added visuals from The Elegant Universe (NOVA), Stephen Hawking's Universe, Cosmos, the Powers of 10, and more. It is a tribute to great minds of science, intended to spread scientific knowledge and philosophy through the medium of music.
