Symphony of Science

These videos are not new, but I think they fit well in the Seniors' UI into Ecosystems -

First is The Poetry of Reality (An Anthem for Science)

Then, watch 'The Unbroken Thread'

and 'We Are All Connected'

The project's web page explains more about the videos:
"The Symphony of Science is a musical project headed by John Boswell designed to deliver scientific knowledge and philosophy in musical form. Here you can watch music videos, download songs, read lyrics and find links relating to the messages conveyed by the music.

The project owes its existence in large measure to the wonderful work of Carl Sagan, Ann Druyan, and Steve Soter, of Druyan-Sagan Associates, and their production of the classic PBS Series Cosmos, as well as all the other featured figures and visuals."

You can download the videos, and the read the lyrics.
