At the interview on the job did not provide first hand to a future employer (a man) just waited until he can. Do you make a faux pas?

orbital notation hydrogen Human colony population numbers?  
As a few interesting posts of recent have been concerned with _base_s on Mars and with the most recent with terrarforming Mars. The end result must be self sustaining colonys in another star system for famlies, and even closer to home Mars is to far for quick aid to arrive so the colonists would have to be self sufficent in the short term. As colonists are human beings, the males and females will over time form relationships, and by human nature tend to pair up, and will want to have children. Any body know what the safe number of men and women is to ensure that the genitic diversity is big enough so there is no incest or cross breeding within the colonys population? I have read that 30 men and 30 women of child bearing age with each woman producing 2 children by 3 differnt men for 2 generations is the minimum number that a colony can have in order to maintain genitic diversity, before additional colonists arrive, and the danger is past, and the colonys population aquires a natural population growth rate, and gentic diversity.

Well, there's some question in my mind that you _must_  preserve genetic diversity

The only way I can parse that would be 2 children by each 3 fathers, ending up with her as a grandmother of 36, which certainly would qualify as unnatural population growth.  I would venture to guess that any colony economically able to sustain such a population explosion, anywhere in the solar system, would attract new immigrants at a high enough rate to make genetic diversity by family planning totally moot.         /Paul

That's an interesting point: if you are mostly concerned with establishing a colony with the minimum outlay, barring psych issues, it would seem to make most sense to put your money into sending just females and sperm. Not good news for adventure- hungry young men... Yeah, but think of the stow-away potentials!

A few days ago we wrote cars.money4car.co.uk rent a property silencer about the debt, which has caused the Pamela Anderson, as every year, changing the decor of his house. The owner of the famous zgranulowanych breast wished costly and sophisticated alterations, and when the contractor sent its bill Ceased to answer calls. Currently, debt is more than 1.2 million dollars, but Pam car supermarket Bungalow paddeln insists that ... There are no debts. I am completely financially stable, and I thank all those who contested the recent media reports - wrote in a statement issued yesterday Anderson. It is true that I am still in the course of discussions with some of the subcontractors working on my house. But that's because after paying millions of dollars for its construction still get a wrong call for payment of accounts. My lawyers check out how the work Gurtbänder Übernachtungsmöglichkeiten Ostsee used cars has been done and whether professionals actually have the right to require such enormous sums. Where appropriate, it will pay, if not - it does not. I am only sorry that one of the performers went with the whole affair to the press.
