One day he volunteered to mash some potatoes that she had cooked in a pressure cooker. You know where this is going. "I overheard him in the kitchen grunting and shouting, 'I can't get this lid off, uggghhhh, uggghhhh,' " she says. "I heard a huge bang that sounded like the day the universe was born. I rushed to the kitchen, and there the big guy stood with the pressure cooker in one hand, the lid in the other, and steaming potatoes exploded onto more than half of the kitchen. We're talking the ceiling, walls, cupboards, stove, everywhere. I never knew potatoes could explode like that." ONE OVEN DESIGN THAT'S ABSOLUTELY DYNAMITE After watching Julia Child, Janice Kelly of Grand Praire was inspired to make an "authentic curry." Ms. Child recommended heating the coconut to facilitate removing the meat from the husk. "One rather vital bit of instruction I missed was to drain the milk from the coconut before heating," she says. "I put the coconut in the oven, set the timer and went off to a meeting. When that steam-powered bomb exploded, it blew the oven door off and spewed coconut milk about 10 feet in all directions! I returned to find the oven door dangling from one hinge. I cooked on that GE wall oven for another 20-plus years - all with a coconut-sized divot in the door." YEAH, WELL, AT LEAST THE ALMOND SLICES ARE GONE When Donna Graebner of Dallas was young, she and her sister watched their mother ice an angel food cake and sprinkle it with almond slices. Some fell into the hole in the cake's center. "Mom didn't want to cut into the cake in front of the guests only to find a mess of almond slices stacked up in the hole. So she got the hose to our vacuum cleaner and stuck it down the hole. As soon as we turned it on, almost all of the cake was sucked up into the vacuum cleaner. What a disaster. She had to pull the remains of the cake out . . . and wash out the hose. I don't remember what she ended up serving." AFTER THREE ROUNDS, BIRD CONCEDES DEFEAT Carrollton resident Estela DeLa Fuente had never cooked a turkey this big: 22 pounds. She rose at 5:30 a.m. to wash and stuff it, place it in a cooking bag and pop it in the oven. She was headed back to bed when she noted a "glow": The bag had ignited. She removed the turkey, pitched the bag, basted the bird and put it back in the oven. Only now its string cradle was dangling over the pan. "I peered into the oven to see a small flame eating its way up the string, much like you see a fuse burning toward a stick of dynamite in the movies!" she says. Out came the bird. Off came the string. An hour later, the smoke detector went off, waking everyone in the house. One of the wings had dripped fat, which caught on fire. "After the third fire, I wasn't sure whether I'd ever get the turkey to the table," she says. "But he did manage to get cooked and eaten, with a lot of good-natured teasing from everyone." AND FOR HER NEXT TRICK, SHE WILL LICK DRY ICE Dallas native Lynda Doty was making caramelized sugar for her family. "In an unthinking moment, I lifted the wooden spoon to take a quick taste of my delicious-smelling concoction (don't all good cooks taste as they create?)," she says. "The caramelized sugar adhered the wooden spoon to my tongue! There I stood, alone in my kitchen with a large wooden spoon dangling from my tongue, not knowing what step to take next, and all the while realizing that whatever I did, it would be wrong!" She finally loosened the spoon with ice water and butter. "The holiday went on as planned, although I did lose a few taste buds that day!" she says. "INSTANT" RECIPE FOR GUARANTEEING YOU NEVER EAT A POTATO AGAIN After moving here from Korea, Sue Chase decided that if others could cook, she could, too. She began with instant potatoes - "thinking that if they were instant, it would be easy to make," she says. The potatoes looked too moist, though, so she added another package of potatoes - which made the mixture too dry. "To make a long story short, after going to the store and purchasing two more boxes of instant potatoes, I had a pan of potatoes for an army mess tent. Since there were only four in our family, we ended up eating a variety of mashed potatoes (pancakes, croquettes, etc.) for the next seven days." NEXT TIME, WE RECOMMEND A HEARTFELT POEM Allen resident Angie Houghtlin's younger sister decided to bake her way to a young man's heart. The tool: chocolate cake. "My sister, who, to this day has absolutely no interest in cooking, and who still eats cereal for almost every meal, really outdid herself," she says. "When my brother and his friends sat down to cut the cake, therein lay a surprise. Not one of the eggs had been mixed into the batter. There they lay, in all their hard-cooked glory: whole and with yolks intact. She has never lived this down." IT'S FUDGE, I SWEAR IT IS Eager to impress her new husband, Michelle Padgett Perkus of Richardson decided to make her mother's fudge. She cooked the mixture until it was hot and bubbly but could not get it to the "soft ball" stage. Convinced the batch was bad and lacking a garbage disposal, Ms. Perkus did what many a young bride might do. "I dumped the hot fudge failure into the commode," she says. "The whole 4 cups of hot fudge splattered to the bottom of the commode, where it quickly formed a soft ball. When I tried to flush it, the brown gooey glob of fudge firmly attached itself to the bottom of the commode and refused to flush." Her husband came home. He laughed, she cried. "The worst part was having to spend many hours digging that fudge out of our commode with a spoon!" she says. THIS DIVINITY SURE DOES TASTE MIGHTY ... REGULAR It was back in the late 1930s that Thelma Hopkins' sister made one very unusual batch of divinity. "I can remember it and smell it like it was yesterday," Ms. Hopkins says. "We started to eat it and realized she had used Fletcher's Castoria (a strong Laxative) instead of vanilla. There were six of us kids so you know we didn't throw it away. We ate it. We passed each other on the way to the bathrrom, but we survived and laugh at it every so often." JACK FROST, GET OUT OF THE COUNTRY. ASAP. Dallas resident Jeannine Verinder has always liked the part of that song that goes, "chestnuts roasting on an open fire." "Several days before Christmas one year, I happened to notice chestnuts for sale in the produce section, so I bought some," she says. "My husband and I didn't have an 'open fire,' so I decided to roast them on an open cookie sheet in the oven. Was I ever surprised when the chestnuts started exploding. We spent hours cleaning those fibers off the inside of our oven." DRIVEWAY STILL SOLID AS A ROCK As a young bride, Jan Wallace of Mesquite didn't want guests to see her relying on a cookbook. When they arrived, "I hurriedly put away my cookbook," she says. "I remembered that the recipe for gravy called for one 'something' of flour and unfortunately I chose the word 'cup' to replace 'something' and added a cup of flour to the grease. I added and added and added milk and it was so thick we could have used it to pave the driveway." At her guests' suggestion, they skipped gravy altogether. MM-HMM, RIGHT. MEANWHILE, CHECK ON THE KID'S LIFE INSURANCE POLICY Virginia Davis of Dallas insists she is not stupid. No, she was simply young and inexperienced in the ways of canned ham. She stuck the can in the oven for just a "few minutes" to melt the gelatin around the edges. Then she forgot about it. Company arrived. "Just as our nephew passed the oven, it happened - the oven door flew open and the exploded ham flew out of the oven, missing the child's head by inches," she says. "As it hit the wall, the shredded ham was flung across the kitchen and was literally hanging from the ceiling. I remain extremely thankful that I did not kill my nephew with an exploding ham." THAT'S NO HAM, THAT'S MY ... John Lowrey was working days, his wife Mary nights. He came home one night and noticed an unfamiliar smell. He went into the kitchen and saw "something round" on the floor. "At first I thought that an intruder came into the apartment and killed my wife and cut her head off," he says. He turned on the kitchen light. "I saw 'stuff' hanging from the ceiling, curtains, walls and floor!" he recalls. "The oven door was open and there was a twisted thing on the floor. After calming down, I looked closer. The twisted thing was a ham can. The ball on the floor was an exploded ham and the 'stuff' all over was more ham." The instructions never said to remove the ham from the can, said the Mrs.; it just said "cook at 325 degrees." "You know, she was right," he says. THAT BARB ALWAYS WAS A LATE RISER Lynn Dickson's mother-in-law brought over her bread machine so that Ms. Dickson and her husband could try it out. She also brought a plastic bag of powdered milk, which she said would improve the flavor of the bread. Her husband tried it and made what seemed to be a perfect loaf. But he threw it away; he didn't like the crunchy texture. That evening, Ms. Dickson noticed that a small plastic bag containing the cremated ashes of her deceased sister, Barb, was missing from a table in the bedroom. "I had recently flown back from out of state following her funeral with her ashes in the bag until I could locate a suitable permanent container for them," she says. "When I questioned my husband as to where 'Barb' was, his eyes widened and with a grief-stricken look on his face, he exclaimed, 'You are not going to believe what I did! I put her in the bread!!' In a state of shock, I asked, 'All of her?' 'No,' he cried, 'Just two tablespoons!' " Unsure whether to laugh or cry, they finally began to laugh, knowing that Barb would enjoy the humor of this incredible story. "We thought of many humorous sayings at that point, such as 'Well, Barb always wanted to be rolling in the dough!' or 'Barb was so well-bred!' or 'Barb has truly risen!'

Have you looked at the GNU gmp library? It's free with source and documentation and includes at least simple transcendental functions (I think). It is written in C and includes assembler code for many processors. There's also a C++ wrapper ("cln") for it that is, of course, much nicer to use because you have overloaded operators (really nice to write "z = z * z + c; when z is a 200-digit complex number :-). I thought about implementing a deep zoom fractal engine with it recently, because it includes algorithms for multiplication that are better than O(n^2) like fractint (O(n log n) and O(n) even, I think). Probably that would be useful only with *really* deep zooms, though...

This is my first post to the list.  I'm a relative fractalint newbie.

Can someone please enlighten me on the following:

Our local PBS station out of LA (KCET) recently aired
 a program on Fractals, hosted by Arthur C. Clark.
I believe some of you saw it, as it was mentioned some posts past.

In it, the developer/owner of Iterated Systems was interviewed.  During his
interview there was a demonstration of a software filter which was
used on a severely data reduced (pixelated) image of a part of a
parrots eye.

By passing the data set through the filter one obtained a substantially
enhanced image at seemingly higher resolution than the original low resolution
image.

Could some of you out there in the "know" on these sorts or subjects
please comment on this.

Historically, we have never been able to obtain high rez output from
low rez input, regardless of the processing applied.  You can't create
"information" out of nowhere.

But I suspect, due to the observed self-similarity exhibited in fractal images,
using a "reverse fractal filter" (for lack of a better name), based on
fractal mathematics, would result in output which probably resembles the original,
rather than an exact recreation of it.  

Does anyone know if these processing techniques have ever been applied to astronomical observations, say image data from the Hubble Space Telescope?

If one can recreate the parrots eye from a hand full of pixels, wouldn't it be
possible to fractal process an image taken at the limits of an instruments
capabilities and effectively multiply the power of that instrument
10's or 100's of times maybe 1000's of times?

I apologize if I've posted this to the wrong newsgroup, but it seemed
like a good first approximation.  Please advise me of an alternate if one
is aware that such exists.

Even JPEG and GIF compression (one lossless, the other with a restricted palette) are too damaging to the data to be used for recording purposes. In fact, FITS files are not limited to two-dimensional images (one- and three-dimensional images are also common), and its headers can contain massive amounts of data - not just a description of how many images there are in the file, and the number of dimensions and bits per pixel each image has, but notes on what telescope took the photo, what instruments were attached, what wavelengths were gathered, what part of the sky is in view, catalogue numbers of any objects in the view, UTC timestamp... One reason for the aversion to compression in FITS images is the age of the format (it was designed to be conveniently stored on punched cards). FITS files are no doubt tarred and gzipped for archival purposes (perhaps with a summary of the header stored separately for indexing), but that is not strictly an image-compression issue. The other reason is that in astronomical photographs _every_ bit is considered significant data - considering the amount of effort that has gone into obtaining it, this is not surprising! > >If one can recreate the parrots eye from a hand full of pixels, wouldn't it be >possible to fractal process an image taken at the limits of an instruments >capabilities and effectively multiply the power of that instrument >10's or 100's of times maybe 1000's of times? > The extra "information" would still be fake.

(It's not Christmas anymore!) The main effect of this is in the cycling and something disturbing is happening at the edges. I think some of the house guests watching this were on the verge of a seizure like those children in Japan watching animations.

When I'm looking at fractals on the web, I so often wish the artists had taken a little more time experimenting with the "perfect" color map. The precise control Fractint provides over color mapping is one of its most wonderful features. I hope.....if we go to true color....there is some way to produce something like a palette....or turn certain areas of the fractal black like we can do in Fractint.

The same 'restoration' technique can be used to recreate any self-similar object when a bare minimum of information is available; easy examples are pictures of clouds, wood and stone surfaces - add a little randomness and your computer can produce pictures which look like the real thing. Unfortunately, these approximations cease to match the real world if we magnify or change the scale very much. The approximations tend to look exactly the same no matter how much you magnify, whereas things in the real world reveal new features (cells, organelles, molecules, atoms, etc.) as you magnify... this is linked to the fact that different forces in our universe act over different distance scales. So we couldn't use a fractal algorithm to improve our data; we could only make our data simulate a standard, but any new, 'true' information would appear strictly by chance. Ok, that's my brain. Two more things: 1) The Mandelbrot set is a fractal that exhibits the phenomenon of novel geometry at all scales (well/poorly phrased?), and thus is fun to explore, and 2) keep asking questions, even this one again, if I butchered my explanation and no-one else responds. Others here can provide a much more technical answer than I can. Again, welcome, and Happy New Year!

Anyone who wants to download the stuff and mess with it is welcome to, at their own risk, but the disclaimers make that point clear (prob'ly scare folks off, actually... hmmm). I've got a little more updating to do to the readme.1st file this morning to describe what the code does... basically the program chooses a pixel at random, but the liklihood that a pixel will be chosen depends on its 'color' (iteration value) so that 'deeper' pixels have a higher chance of being chosen. The winning pixel 's (x,y) location is used to center a zoom box on... but this'll be in the readme.1st file if you want the whole story. Basically, the zoom algortihm is random. I'm working on a smarter algorithm... I've also decided to develop this as a standalone add-on (like the Filmer program is) because I think I know how to proceed with that. Ideas and suggestions still welcome!

Care and Feeding of 3D_Balls_Mset You're going to need those parameters and colors to make your own 3D Ball images, boys and girls. So if you try to bake these at home, you may want to load 3dballs.par after you have located an interesting MSet region using standard formula. The initial un-zoomed MSet shows up mostly black without detail using Paul's formula. So locate a midget or Misiurwicz point, and note the coordinates and magnification. Then load 3dballs, enter your coordinates and you are set. 3dballs { ; Copyright (c) Paul W.

When you are using Flarium, under "view" there is a choice "color parameters" that gives you a screen "Flarium 24 color controls" You can specify a number for R G B that will change the palette. There is also a choice for color cycling under view and also in the color controls. I don't think you can change the colors by choosing or importing a palette like you can in Fractint. I have been spending endless hours on the "Inkblot- Kaos" program from Iterations et Flarium. It is simpler than Flarium. It makes incredibly nice images-some of the Julia sets are luminescent and mandala-like and most people who don't know about fractals are very impressed. Quite a few could be book covers. You don't have the sense that you are making an image "from scratch" or using math like you do in Fractint but it's fun and easy. I think these programs are from Stephen C. Ferguson and you are imposing the "stalks" and "bubbles" which are Paul Carlson's method (tell me if I have this wrong!) I think it is great that people have made these as freeware, (like fracint itself and truemand etc.), not that I would mind paying money for them but it makes me feel like someone has done something creative that they care about. - Thanks for using Fractint, The Fractals and Fractint Discussion List Post Message: fractint@xmission.com Get Commands: majordomo@xmission.com "help" Administrator: twegner@phoenix.net Unsubscribe: majordomo@xmission.com "unsubscribe fractint" ------------------------------------------------------------------------------- From: "B Michie" Subject: Re: (fractint) Pickover Phoenix Formula Date: 29 Dec 1997 06:28:43 +1100 Would you mind giving me Paul Carlson's homepage address please.

DEEPZOOM(tm) was introduced to the world back in '93. It has since been stored in a vault at Spanky, but now that it has been rendered harmless, it is lately available at my page (you will understand): http://www.geocities.com/CapeCanaveral/Lab/3825/Software.htm Someone in Alaska had bragged of zooming to 44 digits using BASIC. Another complained of a deep zooming program that set you back $90 (a lot in those days). $90, and 44 digits! I could not stand it, so that very evening I wrote DEEPZOOM. The next day I released it upon the world. Oh, if only I had known.... Arthur Clarke had warned us. A lively discussion followed as 13 versions were announced. I quote here a few postings from that time in the distant past which included repeated warnings and even an example 70 digit zoom. In those days of 486/66 machines, there was little hope for any who caught Zoom Fever. Machines and eyes were locked up for days as the little white dot slowly crossed the screen. The fever was speading. Those who could not get it, wanted it. I tried to control the technology, only releasing executables and hints of how it was coded. But it was unstoppable! It was only a matter of time... Finally, extended math was added to Fractint, dooming my DeepZoom and all (about 270) who had a copy of DeepZoom. DeepZoom's grasp was replaced by an even tighter grip, Fractint's, which even the fastest Pentiums have not broken. And now, with Deeper.exe, our fate is sealed. We are caught in the trap where not even a twitch of the finger is required as the lock is now automatically maintained through ever deeper zooms. It only takes the pressing of a single key to release us, but not one of us can make the slightest move. The body becomes totally frozen as the eyes search the depths for the tinniest midget.... Oh, if only I had known....

Hill In an email I was asked: > A naive question at a late date: what's Mandelmania? In the novel, MSet pictures were everywhere by the turn of the century. Some people just couldn't handle the infinite detail and beauty. They had to see it all, experience it all. Some let it get to the point of an incurable Mandelmania. No cure. Well, about 80% make an 'adjustment' back to normality by use of medications and for some, as Clarke indicated, implants - duuh. The real line portion of the Mandelbrot Set provides an exhibit of several types of iteration behavior. Outside of the interval (-2..0.25) iteration diverges. An example of a Misiurewicz point is -2. Then inside the buds and cardioids the iterations become periodic. On the edge of a bud or cardioid iteration convergence is very slow since the Lyapunov exponent is 0. Other points are chaotic with Lyapunov exponents greater than 0. But the Lyapunov exponent is defined in the limit of infinitely many iterations. Without carrying the calculation to infinity, can we determine if an arbitrary point is chaotic? I doubt it. Aha! An excuse to ZOOM! The Lyapunov exponent for c=-1.8 is approximately 0.4046 which certainly looks chaotic. I wondered what the MSet looks like if I repeatedly zoom in on such a chaotic point. So I used DEEPZOOM to do just that. With -1.8 in the center, each increase in magnification shows the point -1.8 missing midgets repeatedly, with small ones near -1.8 always moving just out of reach. Finally, at 10^68 magnification I moved the focus over a pixel or so to a midget right next to -1.8. The final view at 10^70 magnification is shown in 18000000.gif which I just posted to alt.binaries.pictures.fractals. The gif took more than two days to compute on my 486/33. The deepzoom parameters were maxiter = 3200076 x = -1.79999999999999999999999999999999999999999999999999999999999999999941756 y = 962e-72 dx = 1280e-72 dy = 960e-72 My warning post (see above) got a few interesting replies. Alas, it looks like it's too late. One reply was, in part, "...seeing as how my brain is already warped and locked into a permanent ZOOM state...". And this. "You can add me to the 'mentally locked up Mandelbrot Zoomers Set'. I have recently downloaded DEEPZOOM, and have started playing with it. It's great. This program is just another great reason to leave my computer on all night." The current version, 0.10, has an improved color scheme using 108 rainbow colors before repeating. Also, I have added a sleep mode which aids TSR screen grabbers. In four days, DEEPZOOM will be two months old and is still FREE. ;-) Maybe by then (Real Soon Now) I will add gif-ability. Then automatic generation of a gif sequence which can be used for an mpeg ought to really jam my machine. If we magnify by a factor of two, there are obvious reuse of calculations from the last view. There should be information reuse even if the magnification jump is 15%. Any ideas?
