About this deal

In 2006 Dean Astumian of the University of Maine in the US suggested that in the case of microscopic engines, equilibrium means something rather more subtle than the definition that Kelvin and Clausius had in mind. Rather, Astumian argued, there are many flavours of equilibrium. For example, in a mechanical sense Bustamante’s stretched RNA is at equilibrium, since at any instant during the motion of the molecule the forces of fluid drag and random Brownian motion are as good as balanced (if they were not, the molecule would be accelerating, which is not the case even for fast stretching). So, in one way these experiments are still investigating equilibrium thermodynamics, and hence can give equilibrium measures.

The 1990 season [ edit ] The Life L190 at Goodwood Festival of Speed 2009 driven by Arturo Merzario Vita's plan was to sell the engine concept to a well-funded Formula One team. During 1989, he searched for a partner without any success. Finally, he gave up his search and decided to run the engine on his own in the 1990 Formula One season.

By describing how energy is converted into different forms in macroscopic systems, the laws of thermodynamics were key to the success of the Industrial Revolution Despite being a very complex tapestry of interconnected chemical reactions contained in cells, life is governed by the same fundamental principles as fundamental chemistry. In its fight for survival, laws such as that energy is neither created nor destroyed and that the universe tends towards entropy lay the ground rules for life. Gibb’s free energy emerges as a critical player, determining the spontaneity of these chemical reactions. Organisms, as tiny biological machines, have the ability to harness the energy released by spontaneous chemical reactions to drive their metabolism.
