Fractal
visionaries
and enthusiasts:
Believe it or not, today's image has the same 'C' coordinates in the
Mandelbrot set as yesterday's. But the appearance has totally
changed. The central minibrot as well as everything around it
has
vanished and been replaced by a series of 14 converging arms.
The reason for the change is the real(p3) parameter, which has been
raised from zero to 0.248 and thereby offset the slice ever so slightly
in one of the other six directions that are perpendicular to the plane
of the image in the 8-D Julibrot.
The name "Mystery Epicycles" refers to the 14 converging arms that have
replaced the minibrot. The number 14 is strange enough, but
the
next deeper series of converging arms, barely visible at the center,
numbers only six. I have no idea what determines these
series, so
they are still a big mystery. BTW, epicycles are what the
strange
retrograde motions of the planets were called before we knew the nature
of the solar system and the laws of gravity.
The art aspect, which in my opinion is a little better than
yesterday's, rates a 7. The math aspect reveals its full
mystery
in today's image, and honestly earns its superior rating of a 9.
The calculation time of 11 minutes is definitely slow, making the web
sites a far better way of viewing the scene.
Clouds moved in just after noon here at Fractal Central
today.
Things were not as bad as they might have been however, as the
temperature reached 46F +8C. The fractal cats grumbled when
the
sun was obscured just as it reached their window shelf. The
fractal humans simply did their usual grumbling.
The next FOTD will be posted in a moderate number of hours.
Until
we find out what moderate means, take care, and the perfect SAT test
would be one in which every student scores the same mark. But
if
we ever achieved this ideal goal, why would we need the test?
