The (elegant) science of "Incarnation"

It does a pair of months the magazine "Quo" got in touch with me to propose to me to write an article where he should report to his readership the principal scientific errors that were committed in the science fiction movies. Of course, I accepted with enormous taste and illusion. I me started working and sent it to him.
When the definitive version of the article was still not ready and coinciding with the premiere with the movies of the movie of James Cameron, Incarnation, they proposed to me also on the march the second article where he was commenting on the science (good or bad) reported in the cinematographic sensation of the year. And this time I did not also allow to spend the opportunity, since it was very wanting to drive in the tooth to Pandora and to the na'vi.
Some weeks later, two articles have been checked and infografiados marvelously and spectacularly for the team of "Quo". They will see the light in the next number of the magazine, 174, corresponding to March, 2010 and that will be in the kiosks from the next week. Do not get lost it! But that is not quite, so very nicely the magazine has agreed to pre-publish a version online complete of the second one of the articles that I have written for them: "The science of Incarnation". If you puncture in the previous linkage you will be able to read it to yourselves of free form from the proper web page of the magazine.
Finally, it would not be just not to quote the work previous to my friend, companion and alumnus, Iván, who published an article previously on the same topic in his impressive blog Wis Physics. If you compare both versions you will realize the quantity of similarities that exists between them. I have to say in my defense, nevertheless, that I did not know his version even after mine sent the publishers, due to a problem that Iván had with the servant of his web. This way, then, I can only dedicate the article with my biggest admiration and respect.
