ROTATING POLYGONS and ROTATING WEATHER COCKS

‘SStanding Wave Theory’ *Why moSeS and the Vikings had Horns

Rotating Polygons.Rotating Polygons.

“Nobody predicted that it should behave like this,” Bohr continues. “You start with something that is completely circular, basically like a hand without fingers, and, suddenly, out of nowhere, fingers develop. The fluid is pressed against a round wall, at first in a circular shape, but it wants to become something else, to develop a corner.”

Bohr finds the mystery fascinating. The circle shape demonstrates instability, but when it develops into a polygon (and Bohr’s team has found that the polygon can have anywhere from two to six sides), it becomes quite stable and can remain the same for hours. In some cases there can also be slow transitions from one polygon to another.

The findings are related to geophysical phenomena around us. Bohr explains that similar forces are at work on our own planet: “We live on a rotating sphere, and fluids abound in the oceans and in the atmosphere,” he explains. “Our experiment might help us know the basic instabilities and properties of systems like that.”
