e earliest and greatest was Leonardo da Vinci, who made many careful studies of turbulent motion and became obsessed with the IDEA that A GREAT DELUGE would one day ENGULF THE EARTH.
In his observations and drawings of rapidly flowing water, Leonardo noted how vortices tend to fragment into smaller and smaller vortices, which then fragment again. The whole process en route to turbulence appears to involve endless subdivisions or bifurcations at smaller and smaller scales. Where do these bifurcations end? Is there a limit to their number? A fluid is ultimately composed of molecules; is it possible that true turbulence persists right down to the molecular level, or beyond? The notion of vortices within vortices ad infinitum suggests that systems close to turbulence will look similar to themselves at smaller and smaller scales - suggesting that the strange attractor of turbulence is a mirror-world.John Briggs & F.

he Meteorological Agency said. The epicenter was located off Chiba Prefecture. No tsunami warning has been issued.
When Japan’s earthquake-battered populace feels the ground shake, it looks to its TVs and Twitter feeds to check not only the magnitude, but the shindo, or shaking intensity.
On every TV channel, digital overlays report the region hit and show waves of numbers rippling away from the epicenter: one area might register as shindo level 3, defined as “felt by most people in that zone,” another as level 4 (“most people are startled”). The first magnitude estimates typically come later.
The quake came as Typhoon Hagibis, one of the most powerful storms to hit the area in years, was set to make landfall further west in the Kanto region.

All who reach this gate, fear to enter.”
To overcome this fear, one must enter it with the suddenness of a knife-thrust.
It is the very gate, of birth, and death, and re-birth.
