Closed Hilbert Curve

After finding a topic on Continuous Fractal Space-Filling (Hilbert) Curves ...

... in a math-book in the library this week ...

... I started looking for them on the internet and came across a neat tool on the Wolfram-site:

http://demonstrations.wolfram.com/InterpolatingTheHilbertCurveWithABSpline/

(CDF player: http://www.wolfram.com/cdf-player/ - 200 Mb or so)

But because the curve was open, I asked the developer Dr. Michael Trott if he could ad a closing option, like the picture in the book … and hey! he send me this adjusted cdf-file/code where the loop is closed ... et voilà there was the Fig. 8 knot, check it out:

Yellow and purple are the tangent at the closest points, white connecting line is the shortest distance between ellipses, long white lines are tests for: http://en.wikipedia.org/wiki/Hyperplane_separation_theorem

War of the Ants

TV noise is a fun reference for the Aether medium.

See post: Spiraling Figure 8

Noise, in analog video and television, is a random dot pattern of static displayed when no transmission signal is obtained by the antenna receiver of television sets and other display devices. The random pattern superimposed on the picture, visible as a random flicker of "dots" or "snow", is the result of electronic noise and radiated electromagnetic noise accidentally picked up by the antenna.

Since one impression of the "snow" is of fast-flickering black bugs on a cool white background, in Sweden, Denmark and Hungary the phenomenon is often called myrornas krig in Swedish, myrekrig in Danish, hangyák háborúja in Hungarian, and semut bertengkar in Indonesian, which translate to "War of the Ants" or sometimes hangyafoci which means "ant soccer", and in Romanian, purici, which translates into "fleas".

Tippy Top

A 'Tippy Top' is a spherical object like an oval/ellipse with its center of mass out of the middle when spun. The reason it tip's over has got to do with Momentum of inertia, Torque and Force of friction.

Extreme Vortex Confinement

Simulation made by JAHC

Vorticity Confinement has a basic familiarity to solitary wave approach which is extensively used in many condensed matter physics applications. The effect of VC is to capture the small scale features over as few as 2 grid cells as they convect through the flow.
