5.0 out of 5 stars
Most human of all books on interstellar travel, October 6, 1999
By A Customer
Most other books about interstellar travel are the same, talking about only the technology. But this one talks about the human part of it. The ideas range from "why do it?" to "it's all sooo easy!". The multiple viewpoints are very interesting. I would recommend this to anyone interested in science fiction and/or space travel.

5.0 out of 5 stars
It covers all the problems other than propulsion, September 26, 2006
The better nuts and bolts books about interstellar travel cover propulsion. This one is different. It compares interstellar migration to the only comparable effort ever before made by people, the exploration and conquest of the Pacific Ocean islands by Polynesians in outrigged canoes.
I think the most interesting articles for me were about the economic and genetic effects. For example, economically, colonists in a starship may find it very difficult to take enough skilled people with them (10,000!) to maintain an industrial civilization. Also, ramping up the tools, the physical capital, to actually settle a distant solar system is not credible with actual, existing systems: We need to minimize the shipped mass, so we start with... a blacksmith hammer and build Western Civilization? How much stuff do we take? Or the genetic founder effect: How many people is the minimum for a genetically stable population? Well, if they are from different ethnic groups, maybe as few as four to six mothers, and a sperm bank. Otherwise, about 300 is the minimum (ouch).
If you care about this stuff, get the book. It's cheap at the price.
