As far as I can tell, it iterates z = k(az^b + bz^f)+c (a strange choice of variable names, but hey...) I notice from the way the formula works that both the coefs and exponents have to be purely real. Then there's just the small matter of z0... I'm not sure, but isn't (-abgh)^j the same as the (f-b)th root of (-ab)/fd? And if so... why?!? I find it hard to belive that it just seemed like a nice expression to initialise the orbit to... Another question: when E is not a positive real integer, Z^E is multivalued. How about if E is an imaginary positive integer? Is it multivalued or single valued? Whimsical observation: Z^0.5 is double-valued; Z^0.25 has 4 values, z^0.1 has 10 values, z^0.01 has 100 values... by induction, z^0 has infinity values ;-) [of course, since the solutions to z^0.5, etc get progressively closer together, at z^0 all the infinity of solutions are THE SAME ONE: "1"] Andrew.

FOTD 30-06-02 (Algae [7])

FOTD -- June 30, 2002 (Rating 7) Fractal visionaries and enthusiasts: Today we rise one step out of the rating-of-six rut that we've been mired in for several weeks, all the way up to a rating of 7. The rating seems fairly accurate, considering the unusual textures created by the reference standard outside coloring method of equal iteration bands. Normally, the powers of Z between 0 and +1 do not make fractals, but by using certain tricks, fractals can be coaxed from these powers. One of my favorite methods of getting fractals where none exist is to take the difference between two non-fractal- producing expressions and multiply it by a factor sufficient to create an image. In today's case, that factor is 13. The iterated formula subtracts 13 parts of Z^0.7 from 13 parts of Z^0.75 then adds C. The resulting parent fractal is quite sensitive to its bailout radius. In fact, changing the bailout has such a great effect on today's image that I suspect the entire image might be an artifact rather than a true fractal. But artifact or not, the image is worth being included in that ever-growing list of FOTD's. Studying the image, I was reminded of something that I could not quite remember. Then it came to me. The texture of the fractal elements mimics the texture of algae growing on rocks in a swift- flowing stream not too far from Fractal Central. The name "Algae" soon followed. If the bailout radius of today's image is raised, the picture goes totally black. The image evaporates as all the points become trapped. But then the image can be restored in a new form by setting the logmap to 0 and the inside fill to something non-flat, such as bof61. The 9-minute render time is somewhat slow, but fast relief for rendering pain is available in the form of a download from Paul's web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> or from Scott's site at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> The fractal weather Saturday here at Fractal Central was not perfect, but compared to how it can be in this part of the world at this time of year, it was good enough. The temperature of 88F 31C, combined with a hot sun, was warm enough for the kiddies to enjoy a splash in their back yard pools, and the humidity was not so high that the more strenuous activities engaged in by adults became unbearable. The cats spent most of the day just being cats and sleeping. As for me, I've got another curious fractal already waiting for the next appearance of the FOTD, which will be on July 2. (Starting in July, I am increasing the frequency of the FOTD to one every even-numbered day.) Until then, I've got the FOTD-CD to work on and a few fun things to do. Until July 2nd, take care, and do the things that need to be done, while ignoring the things that don't need to be done.

I should have taken the time to edit the political stuff from the version that went to the Fractint list. Such blatantly off-topic material will not be posted to this list again. The philofractal list, which thrives on frivolous debate is a different story. Jim M.

FOTD -- June 27, 2002 (Rating 6) Fractal visionaries and enthusiasts: I enjoy human foolishness and today we have a lot of it. The pledge of allegiance to the flag of the U.S.A. has been declared unconstitutional because it mentions God. I suppose the Declaration of Independence and Constitution are also unconstitutional because they also mention God. And our money is also unconstitutional because 'In God We Trust' is written on it. I wonder why Atheists are so intense in their disbelief. I happen to believe in some-something that in some way fits the description of a God. But I do not become offended when Atheists tell me that I am mistaken, or deluded, or clinging to a crying-towel etc. I simply enjoy the debate, satisfied that I am right and they are wrong, while having fun seeing their futile arguments. Why then do Atheists so often become offended when believers tell them and futilely try to convince them that they are mistaken in their disbelief? Actually, as I see it, Atheism is not so much a disbelief in a god as it is a continued belief in and a defense of the philosophy of positivism, a world-view which, IMO, lost credibility about 100 years ago, and except among Atheists has been declining ever since. As to what world-view will prevail to replace it, I have no idea. But one thing is certain -- a new world-view will need to extend beyond the traditional five senses. Most of the universe is invisible to our senses even aided by the best instruments. And we do have a fractal for today. For a change, there is no quadratic midget at the center. In fact, today's image consists of the entire fractal created by the formula -0.2(Z^(-1.25)-0.2(Z^(-0.8)+(1/C). While studying the image, I had the impression of a butterfly emerging from its cocoon. I named the image "Birth". I rated it at a run-of-the-mill 6. The 11-minute render time can be avoided by downloading the completed GIF file from Paul's web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> or from Scott's site at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> The fractal weather Wednesday here at Fractal Central was hot. In fact, it was the hottest day of the young summer. The temperature of 99F 37C and high humidity kept the cats confined to the shade of the porch and the fractalist confined to the coolness of the air-conditioning. Late in the afternoon a shower threatened, but died out before reaching Fractal Central. Today promises to be a repeat of yesterday, and the cats are already in their lazy mode. As for me, I've got work to do. As long as the air cooler keeps working, I'll be fine. Until next time on the 30th, take care, and see you then.

FOTD 21-06-02 (A Nebular Minibrot [6])
by Jim Muth 25 Jun '02

25 Jun '02

FOTD -- June 21, 2002 (Rating 6) Fractal visionaries and enthusiasts: As I write these words, it is 9:24am EDT, the moment of the summer solstice in the northern hemisphere. The sun is now as far north as it ever gets. Actually, the sun is not located any farther north that it always is, for there is no north and south in space. What has happened is that the earth has reached the point in its orbit where the north end of its axis is tilted directly toward the sun, which makes today the longest day of the year. Today is not however the day with the latest sunset. Because the sun is now falling farther behind clock time each day, the day of latest sunset arrives in about one week. In the southern hemisphere, where everyone hangs from the earth's surface by their feet and Christmas comes in the summer, all this is reversed! Today's fractal is not upside down, but it *has* been rotated to the 'normal' position, with the negative stem actually pointing left, the way all proper stems should point. The image is the latest in the apparently unending series of Minibrots, and as such, features an object sometimes known as an atom, but better known as a Mandelbrot Midget. The formula that created not only today's scene but an entire fractal universe, mixes portions of Z^(-1.16) and Z^(-12.5) then adds 1/C instead of just plain C. I named the image "A Nebular Minibrot". The name is justified because the image does have a galactic feeling to it, complete with stars and greenish glowing clouds of gas. I rated the image at a 6, which is above average but not outstanding. The rendering time, for those who choose to run the parameter file, is a nominal 5-1/2 minutes on my lazy P200 machine. And as always, the completed image will soon be available on the two FOTD web sites at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> The fractal weather Thursday here at Fractal Central was pleasing to man and cats alike, though the cats had more time to enjoy the perfection. Brilliant sun, crystal blue skies, puffy white clouds, gentle winds, and a temperature of 83F 28C made everyone happy. As is usually the case however, I have a bit of work to accomplish before I can enjoy today, which promises to be a repeat of Thursday. Until next FOTD, which will arrive on the 24th, take care, and I'm not as dumb as I appear and not as smart as I pretend.
