February 21, 2012: Scattered Trunks | Feb. 20 | Feb. 22 | 2011 | FOTD Home |
Fractal visionaries and enthusiasts:
The
valley on the
east side of the Z^2 Mandelbrot set is sometimes called Elephant
Valley. The radicals found there rather convincingly resemble
elephants. Every bud has one elephant standing over it, trunk
raised and curled in defiance. The Z^3 Mandeloid has two
elephants guarding every 2-lobed bud in its Elephant Valley; the Z^4
Mandeloid has three elephants guarding every 3-lobed bud,
etc.
The series continues, with the elephants growing ever more numerous and
smaller, always numbering one less than the exponent of Z.
But
what happens when the exponent of Z is reduced?
The same series continues. Today's image shows the elephants,
or
what is left of them, in the Elephant Valley of the Z^(1.5)
Mandeloid. We have half an elephant guarding every
half-bud. And it happens to be the front half of the
elephants
that remains. The image shows disembodied elephant trunks
scattered everywhere, but not a single whole elephant. With
little thought, I named the image "Scattered Trunks".
The parent Mandeloid is a rather shapeless thing that came about when I
returned to the 'MandelbrotBC2' formula and checked East Valley of the
fractal that results when the expression Z^(1.5)+C is calculated 1.5
levels up the logarithmic ladder.
Today's scene lies on the south side of the valley, where the front
halves of the elephants remain. (On the north side of the
valley
their rear halves remain, but elephant rumps are far less impressive
than elephant trunks, so I chose to check the trunks.)
I rated the image at an 8, mostly for its mathematical
interest.
The coloring is a bit flat, though it is smoother than usual and its
flatness does give an atmospheric effect.
The calculation time of 2-3/4 minutes is rather slow by FOTD
standards. This is where the FOTD web sites stampede to the
rescue.
Partly cloudy skies and a temperature of 46F +8C made today an
un-notable one here at Fractal Central. The fractal cats were
annoyed by the come-and-go sun, and settled by the house heat early in
the afternoon.
FL and I had a day as uneventful as the weather. Yes, I know
it
makes boring reading, but I have to tell it like it is. The
next
FOTD will be posted in 24 hours. Until then, take care, and
one
thing absolutely certain is that the end of the world is coming, just
like those 'scare' shows say. The only question is when.
