Uploaded last March, the video was produced by AJ Salas. Dream of Tomorrow features Neil deGrasse Tyson, renowned science advocate and astrophysicist.
Tyson’s speech is from his testimony at the Senate Science Committee in March, 2012 regarding the US governments’ budget for NASA.
I found this to be a really interesting discussion on science, and the nature of science. The discussion was organized by the Richard Dawkins foundation and of course features Dawkins himself; it also features renowned astrophysicist Neil deGrasse Tyson.
The discussion is quite long, so bookmark it for later if you don’t have the time right now.
