1. Different Views on the World?
The largest telescope in the world is the Arecibo Radio Observatory in
Puerto Rico, 1000 feet across (one of the ones Jodi Foster used). The
largest optical telescope (using visible light) are the 10-meter Keck
telescopes in Hawaii. The largest telescope in space is the 2.4-meter
Hubble Space Telescope. The highest resolution images of the Jovian
satellites, however, are from the Galileo spacecraft. Explain how
these four telescopes are different, and how they are the same.

3. What is life?
Write your own definition of life, in several sentences. Is there a
difference in your definition between plants and animals - or other
kingdoms? Should there be? Would a self-replicating robot (a robot,
which is built to build another robot from scratch, which builds
another one, each of them getting better and better) fit your
definition of life? Should it?
