Welcome to Mr. Joseph's Class!
"WELCOME
TO PLANET EARTH a place of blue
nitrogen skies, oceans of liquid water, cool forests and soft meadows, a world
positively rippling with life. In the cosmic perspective it is, as I have said,
poignantly beautiful and rare; but it is also, for the moment, unique. In all our
journeying through space and time, it is, so far, the only world in which we
know with certainty that the matter of the Cosmos has become alive and aware.
There must be many such worlds scattered through space, but our search for them
begins here, with the accumulated wisdom of the men and women of our species,
garnered at great cost over a million years."
- Carl Sagan, Cosmos
