Fractal
visionaries
and enthusiasts:
Today
we enter
"Uncharted Territory", which is what I named the image. Never
before have I checked a fractal with an exponent as close to unity as
1.009, making today's image uncharted for sure.
The graph of Z^1.009 is virtually a straight line, so how is it
possible that a fractal as rich and varied as today's could come
about? The answer is the multi-valued nature of the complex
logarithm.
The complex log is multi-valued. This means that it has many,
in
fact an infinity of values, and all of them are 'correct'.
When
applied to fractals with fractional exponents, these different values
create different fractals, all of which are correct. But
curiously, when applied to exponents very close to unity, as is
today's, these different values create some unexpectedly rich images,
in effect turning a 'sow's ear' into a 'silk purse'.
Today's image lies in one of these 'silk-purse' fractals. The
parent fractal is an apparently featureless ellipse, but a close
examination reveals a tiny bit of chaos on the southeast shore
line. Today's image lies in this chaos.
I used the built-in black-and-white color palette to create the 3-D
effect. Other palettes might have worked better, but an
attack of
terminal laziness prevented me from trying to find one. This
laziness held the rating to an everyday 7.
Typical midsummer weather made Sunday a typical midsummer day here at
Fractal Central. The fractal cats spent the day doing what
cats
do when the temperature reaches 88F 31C -- they stretched out and went
to sleep.
The humans took it just as easy, though we did stay awake at least most
of the time. The next FOTD is due to be posted in 24
hours.
Until then, take care, and don't ask me what I think is wrong with the
new world being brought about by the recent advances in
technology. I just might start to answer.
