Image shows the Z+ end of the CMS tracker (part of the Large Hadron Collider at CERN).From here: In a recent study called “Why did life emerge?”, two scientists, son and father Arto Annila of the University of Helsinki and Erkki Annila of the Finnish Forest Research Institute, offer some insight into the general driving force of life’s origins in terms of thermodynamics. As they explain, all organisms are composed of molecules that assemble together via numerous chemical reactions. Just as heat flows from hot to cold, these molecules obey the universal tendency to diminish energy differences, so that the most likely chemical reactions are those in which energy flows “downhill” toward a stationary state, or chemical equilibrium.
Although the researchers don’t speculate on the specific chemical reactions that created life, they explain that the molecules involved most likely underwent a series of more and more complex reactions to minimize mutual energy differences between matter on Earth and with respect to high-energy radiation from Sun. The process eventually advanced so far that it cumulated into such sophisticated functional structures that could be called living. “The most important idea in our study is that there is no distinction between animate and inanimate,” Arto Annila told PhysOrg.com. “Processes of life are, in their principles, no different from any other natural processes.” In this sense, life is a very natural thing, which emerged simply to satisfy basic physical laws. Our “purpose,” so to speak, is to redistribute energy on the Earth, which is in between a huge potential energy difference caused by the hot Sun and cold space.

The Collagen is aging
My wife and I are followers of the chronicles of Indiana Jones and look forward to the new installment with hope. Of course, we constantly wonder if Mr. Ford is up to the task of keeping up with expectations during scenes featuring action sequences characteristic of Jones movies after all these years. The New Yorker captured the spirit with this cartoon and I decided to plagiarize.
