Interesting

To me it was interesting that the book mentioned that Lowell believed that there were canals on Mars that were used to carry water. Now, science has shown that there used to(?) be water on Mars. 
It also discusses how to travel to spaces similarly to what Carl Sagan just talked about on the episode of Cosmos that I just watched.
Chapter 12 will begin discussing the ruse of radio astronomy.

Finally we get to SETI

Chapter 10 introduces us to Phillip Morrison the professor at Cornell University who thought of using radio waves to search for Extra-terrestrial life.  He was listeningto Bach music at a concert there when a number or events congealed in his mind to come up with using radio waves instead of gamma waves as a signal to other universes.
They then discuss some of the other ideas people had to contact other "people"- planting trees in right triangles, flaming ditches, etc.
One of these people was Precival Lowell who built the Lowell Observatory in Arizona . Pretty cool huh?
