"The cosmos is also within us, we're made of star stuff..."
To celebrate the day you may want to listen to the interesting samplings of scientific symphonies. Who ever said that science cannot be wondorous and poetic?
Symphony of Science - We Are All Connected (Carl Sagan, Richard Feynman, Neil deGrasse Tyson & Bill Nye):
A Glorious Dawn (Carl Sagan ft. Stephen Hawking):
Great thanks to Melodysheep for making these!
Post scriptum: Don't forget Sagan's wonderful books, especially 'Billions & Billions' and 'The Demon-Haunted World'!
