In this talk, aimed at people who have basic scientific training, the monumental deals subject of the origin of life from "first principles" of physics. The question how to understand the existence of complex systems, being the human being the prime example, in light of the second principle of thermodynamics and entropy?, it will attempt to answer the astrophysicist Jorge Melnick with his usual courage and concrete platform.

From the point of view of physics, there is an essential difference between living beings and inanimate carbon atoms groups: the former tend to be much better in the capture of energy from their surroundings and the dissipation of energy as heat.

Although entropy must increase over time in an isolated or "closed" system, an "open" system can maintain its low entropy - i.e., divide power unequally between its atoms - considerably increasing the entropy of their environment. In his influential monograph of 1944 "What Is Life?", the eminent quantum physicist Erwin Schrödinger argued that this is precisely what human beings do. A plant, for example, absorbs sunlight extremely energetic, uses it to build sugars and drives out infrared light, a much less concentrated form of energy. Life, however, does not violate the second law of thermodynamics in this process.
