  11. Constructal law (1996): “For a flow system to persist in time (to survive) it must evolve in such a way that it provides easier and easier access to the currents that flow through it”. This new law of physics stands behind all phenomena of configuration generation: Darwin’s observations Machine evolution (“human + machine species”) River basin evolution, atmospheric circulation, climate, lightning, vascularization, vegetation, animals, turbulent flow, dendritic crystals, social organization, etc.
