Fractal
visionaries
and enthusiasts:
Today's image rates All Math. The mathematical interest is
just
about all it has going for it. The image itself is little
more
than a passing scene in an infinite world of fractals. And
the
calculation time of nearly 2 hours is far beyond reason. In
addition, the exponent of Z that created the image is 1.0005, so close
to unity that no one in his right mind would enter it as a parameter
with any expectation at all of finding much more than smooth and
straight band edges.
Questioning my own sanity, I did enter this value as the exponent of Z,
and in addition I felt fairly confident of finding something of
interest. Today's image is what popped up where nothing
should
exist.
The scene is neither a Julia set nor a Mandelbrot set, but something in
between. The detail in the image is not the organized chaos
that
makes most fractals so interesting. The detail in today's
image
consists of countless discontinuities arranged into half-orderly
elements. If any part of the image is zoomed into, a flat
featureless area will ultimately be arrived at. In ordinary
fractal chaos, the chaotic features continue without limit.
The name "Down in the Boondocks" refers to the exponent of Z, which is
by far the closest to unity of any FOTD fractal so far.
A price must be paid for seeing detail in a fractal so close to unity
however. The price is the need of a very high maxiter,
resulting
in a calculation time of 1-3/4 hours, which is tedious indeed for such
an unartistic image. But help has arrived in the form of the
FOTD
web sites.
The day began with clouds here at Fractal Central, but the clouds
cleared off before noon, leading to an afternoon of sunshine, balmy
south breezes and a temperature of 70F 21C. With rain and
colder
weather forecast, today might have been the last near-perfect day of
the fall.
The fractal cats passed a good part of the day sharing the new
chair. The humans disagreed a bit about politics (as is
standard)
but the day passed uneventfully. The next FOTD will be posted
in
24 hours. Until then, take care, and liberal thinkers know
that
conservative policies are the cause of the problems, while conservative
thinkers know that liberal policies are the cause of the
problems. Neither side appears able to recognize that their
conflicting views of the solution are also a part of the problem.
