We
are about three-quarters of the way through the IYA, the International
Year of Astronomy. It is thus timely to think about the successes
of the year and, as this ASP annual meeting title indicates, forge
a path to a future of continued public engagement in astronomy.
In
this context of public understanding and appreciation of science,
it is important to note the world view into which Galileo Galilei
was born (1564). The accepted cosmology was that there were two
very separate realms: that of the Earth, consisting of soil/earth,
air, fire, and water and on which all was transient, and that of
the heavens or Heaven, consisting of a perfect regularity -- remote
from Earth's imperfections, and eternal.
