Workshop on Scale Relativity: Universe, Life, Societies.

 

Workshop on Scale Relativity:
Universe, Life, Societies

Laurent Nottale, CNRS, Paris-Meudon.
Jean Chaline, CNRS, Dijon.
Pierre Grou, University of Versailles-Saint-Quentin.

Summary:

All great systems such as the Universe, Life or Societies share important common features: they evolve towards complexity, are subject to major transitions and phenomena of acceleration. With this directive line, three researchers, Laurent Nottale, astrophysicist, Jean Chaline, Paleontologist and Pierre Grou, economist and sociologist did reassemble their insights and efforts. The result? The discovery that scale laws might govern the evolution of the Cosmos, of Life or of Economy. A scientific revolution in progress? This workshop invites all researchers interested in physics, biology, economics, complexity & system theory, etc. to discuss the promising framework which will be presented.

Tuesday 5 May, Laurent Nottale will present the theory of Scale Relativity, an extension of Einstein's Relativity. In this framework, quantum mechanics may indeed be founded on the principle of relativity itself, provided this principle (applied up to now to position, orientation and motion) be extended to scales. Many successful predictions and application of the theory will be presented, both in micro and macro physics.

Wednesday 6 May, Jean Chaline asks if the tree of Life might have fractal aspects. He suggest how a fractal mathematical structure can be applied to the tree of Life. Pierre Grou then shows that the accelerating trends in the evolution of societies may also be analysed with scale laws. Laurent Nottale will close the workshop with an attempt to synthesize the different results presented.


When & Where?
Tuesday and Wednesday May 5-6. 

Tuesday, the workshop will take place in room D106, and Wednesday in room D108 (building D, level 1), on the VUB Campus Etterbeek (Brussels, Belgium). Free entrance: everybody welcome!
