This has to be one of the most interesting things I've seen on this site. A close second maybe only to Hanny's Voorwerp. Dark, symmetrical and mysterious; maybe the dark matter in the universe is comprised in part of objects similar to this one? If there are more objects like this out there, I imagine they are difficult to detect.

Are Genius and Madness Related? Contemporary Answers to an Ancient Question
By Dean Keith Simonton, Ph.D. | May 31, 2005

Ever since antiquity, thinkers have associated creativity with psychopathology--the classic idea of the "mad genius." By looking at historiometric, psychiatric and psychometric research one can conclude that exceptional creativity is often linked with certain symptoms of psychopathology. Nevertheless, this relationship is not equivalent to the claim that creative individuals necessarily suffer from psychopathology.

The idea that creativity and psychopathology are somehow linked goes way back to antiquity--to the time of Aristotle. Centuries later, this belief was developed and expanded by various psychiatrists, psychoanalysts and psychologists. For instance, Cesare Lombroso, M.D., argued toward the end of the 19th century that genius and madness were closely connected manifestations of an underlying degenerative neurological disorder. To be sure, this idea has not gone without challenge. On the contrary, humanistic psychologists were inclined to associate creativity with mental health. Nevertheless, the prevailing view appears to be that psychopathology and creativity are positively associated.
So take that, Nurse Ann! :p:

flash, thanks for that page; very interesting, and why didn't any of my chemistry classes include this reaction in a lab? How annoying is that?! :ssmile:

It looks as though the spiral reactions are happening not in liquid, but in some other (firmer) medium. (Of course, I could be wrong about that; just took a quick look at the link.) When I get time, this is something I will have to investigate further. Thanks for the links/video!

Apparently if the reaction is disturbed, the behavior of the expanding waves is changed.

I really liked the two versions of Latin Spanish. The first one sounded like the witch was stark raving mad and, you know, M-A-D! Like this! Note the spiral eye! The second Latin Spanish version sounded like the witch was sweet and mild, although admittedly somewhat, uh, how do I put it? Slightly unbalanced? Mad in a softer way? Somewhat like this?
(Not that this isn't a very handsome person, with a winning smile and philosophical, non-spiral eyes... I'm just saying... You know what I'm saying? I liked the witch's spiral, except when she un-spiralled it and flung it away! So what else was I going to say? That softly smiling guy... he's really handsome...nice eyebrows... nose...and smile... ehrrrhmm...tiptoes out...)

Computer simulation of the Belousov–Zhabotinsky reaction occurring in a Petri dish.
<<There are a number of BZ cocktails available in the chemical literature and on the web. Ferroin, a complex of phenanthroline and iron is a common indicator. These reactions, if carried out in petri dishes, result in the formation first of colored spots. These spots grow into a series of expanding concentric rings or perhaps expanding spirals similar to the patterns generated by a cyclic cellular automaton. The colors disappear if the dishes are shaken, and then reappear. The waves continue until the reagents are consumed. The reaction can also be performed in a beaker using a magnetic stirrer.>>

<<A Belousov–Zhabotinsky reaction, or BZ reaction, is one of a class of reactions that serve as a classical example of non-equilibrium thermodynamics, resulting in the establishment of a nonlinear chemical oscillator. The only common element in these oscillating systems is the inclusion of bromine and an acid. These reactions are far from equilibrium and remain so for a significant length of time. An essential aspect of the BZ reaction is its so called "excitability" — under the influence of stimuli, patterns develop in what would otherwise be a perfectly quiescent medium.

The discovery of the phenomenon is credited to Boris Belousov. He noted, sometime in the 1950s that in a mix of potassium bromate, cerium(IV) sulfate, propanedioic acid and citric acid in dilute sulfuric acid, the ratio of concentration of the cerium(IV) and cerium(III) ions oscillated, causing the colour of the solution to oscillate between a yellow solution and a colorless solution. This is due to the cerium(IV) ions being reduced by propanedioic acid to cerium(III) ions, which are then oxidized back to cerium(IV) ions by bromate(V) ions.

Belousov made two attempts to publish his finding, but was rejected on the grounds that he could not explain his results to the satisfaction of the editors of the journals to which he submitted his results. His work was finally published in a less respectable, non-reviewed journal.>>

Thank you, Rob and bystander, for that journey down memory lane, with a detour to Wikipedia, which lets us all know that "Donovan and Linda have two children together, Astrella Celeste and Oriole Nebula."

In the Galaxy to the left of the spiral binary, is that possibly a supernova????, or just a very close faint star?
