"Turbulence is common in nature -- it is found in weather patterns, river flows and many astrophysical environments -- and is also important for many industrial processes. However, the way in which turbulence arises and then sustains itself is still not understood, despite being a subject of research for more than a century."
Researchers in fluid dynamics at the Delft University of Technology in the Netherlands, under the leadership of Bjorn Hof, observe that:
"Stability theory predicts that the flow of a fluid through a straight pipe should remain smooth or "laminar" regardless of how fast the fluid is flowing. However, in practice it can become turbulent even at moderate speeds. "
Might turbulence emerge along the patterns explored by Stephen Wolfram in his book "A New Kind of Science"? Wolfram writes that "Despite attempts from approaches like chaos theory, no fundamental explanation has ever been found for randomness in physical phenomena such as fluid turbulence or patterns of fracture. A New Kind of Science presents an explanation based on simple programs that for example predicts surprising effects such as repeatable randomness."
The fact is that disruptions caused by turbulences occur in any stable processes and that through the disruptions they provoque, turbulences are responsible for the emergence of destabilizing new paths that eventually lead to later stable environments.
