July 21, 2012: Rectangular Surroundings | July 20 | July 22 | 2011 | FOTD Home |
Fractal visionaries and enthusiasts:
Today's FOTD is
late. The reason -- FL and I took a day off on Saturday.
The image is another view of the strange rectangle in the Z^(2.003)+C
Julia sets. The rectangle itself, or what is left of it, appears
as the narrow blue-edged horizontal slit near the center of the frame.
The image has been double rotated only +1 and -3 degrees from the true
Julia orientation. When the Julibrot is sliced this close to the
Julia orientation, a small rotation makes a huge difference.
A careful examination of the image will reveal that its apparent
top-bottom symmetry is 'almost', and not 'exact'.
The name "Rectangular Surroundings" simply describes the location of
the scene. The rating of a 7 is in all ways average, and implies
average satisfaction on my part.
The four-dimensional geometry of the strange rectangle, of which there
are actually an infinity, is so complex that the rectangle can appear
as almost anything. More of these unexpected and surprising
rectangular distortions will be posted as upcoming FOTD's.
The calculation time is perhaps the best feature of the image.
Even when calculated with the rather complex SliceJulibrot4 formula,
the image finishes in a fireball 35 seconds. All complexities may
be avoided by viewing the image on one of the web sites.
For some reason the latest mass murder has me more revved up than other
similar disasters. The loss of innocent lives is bad enough, but,
IMO, the worn-out knee-jerk responses coming from the media outlets
simply make things worse. Only an idiot would believe we could
solve the gun-violence problem by passing more gun control laws or by
securing more guns to protect ourselves with, but from what I am
hearing on TV and talk radio, the world must be filled with idiots.
I hear suggestions that we must keep guns out of the hands of dangerous
people. This is another good-sounding idea that ain't gonna
work. It is already illegal for convicted felons or seriously
mentally disturbed people to possess firearms, but many mass-murderers
have no criminal or psychotic background.
How would we decide
who among the rest of the 'normal' population might be dangerous and
must therefore be banned from possessing firearms? While
searching the general population for the dangerous ones among us, we
would need to avoid any perceived profiling that might offend a
disadvantaged minority'. And we would certainly not want any
perceived invasion of privacy.
When Fractal Central was located back in Baltimore, I saw 'stop the
killing' rallies organized and held on a monthly basis for at least 30
years. Of course, the rallies merely 'preached to the choir', and
accomplished nothing. It was almost a joke when a drive-by
shooting took place at one of the rallies. Despite the rallies,
the killings have continued at a rate of up to ten a week for over 30
years, and my sister reports from back at old FC, that they are still
continuing.
What is the point of all my talk about things people already
know? I have no idea. But I'll have much more to ruminate
on in upcoming discussions, and maybe as time goes on, a point will
emerge.
There is always an immediate point about weather however. Heavy
clouds covered Fractal Central most all day today, but it stayed dry
and the temperature was a pleasant 75F 24C. Late in the day some
breaks in the clouds appeared, bringing hope of a brighter day to come
tomorrow. The fractal cats spent the day taking it easy, which is
always easy for cats to do when the humans are away.
The day went pretty well for the humans also, who had a day of
antiquing down in Adamstown, which is near Lancaster. The next
FOTD will be posted whenever it is ready. Until that glorious
moment arrives, take care, and everyone knows what is wrong with the
world, but why does no one fix it?
