Pachamagaru River

The Gurupura River (also known as Pachamagaru River,[1] Phalguni River or Kulur River[2]) is a river in the Karnataka state of India.[3] It originates in the Western Ghats and is a tributary of the Netravati River,[1] which empties into the Arabian Sea, south of Mangalore. It gets its name from the town Gurupura situated near Mangalore. The New Mangalore Port and Mangalore Chemicals and Fertilizers are situated on its northern banks. Once upon a time it formed northern boundary of Mangalore city along with Netravati River as southern boundary. (Excerpt: WIkipedia)

One could imagine water flowing past an obstruction. As every hydrodynomicist and white water canoeist knows, if the water flows fast enough, it produces whorls downstream. At some speed, the world stays in place. At some higher speed, they move. An experimenter could choose a variety of methods for extracting data from such a system, with velocity probes and so forth, but why not try something simple: pick point directly downstream from the obstruction and, at uniform time intervals, ask whether the world is at the right or the left.

If the whorls are static, the data stream will look like this: left-left-left-left-left……… After a while, the observer starts to feel that new bits of data are falling to other new information about the system.

Or the world might be moving back and forth periodically:left-right-left-right-left-right-left-right. . . . Again, though at first the system seems one degree more interesting, it quickly ceases to offer any surprises.

As the system becomes chaotic, however, strictly by virtue of its unpredictability, it generates a steady stream of information. Each new observation is a new bit. This is a problem for the experimenter trying to characterize the system completely. “He could never leave the room,” as Shaw said. “The flow would be a continuous source of information”

Where is this information coming from? The heat bath of the microscales, billions of molecules in their random thermodynamic dance. Just as turbulence transmits energy from large scale downward through chains of vortices to the dissipating small scales of viscosity, so information is transmitted back from the small scales to the large – at any rate, this was how Shaw and his colleagues began describing it. And the channel transmitting the information upward is the strange attractor, magnifying the initial randomness just as the Butterfly Effect magnifies small uncertainties into large scale weather patterns. ~ Page 261
