It seems like there should be a more natural definition of what a 3D Mandelbrot set should be. They have this godawful ad hoc formula. My first thought was that we could take the basic object we're operating on to be valued in SU(2), but then it's not clear what the analog of the "addition" step would be.

LB - My first thought was "ornate crochet", too. Now I have an impulse to crochet one of those figures.

Many years ago, a friend of mine developed a pattern for needle-pointing a Moebius strip. Perhaps there's an arcane connection between needlework and maths...

I love how the "paper" in 26 pays homage to the crackpot journal editor:

As well, the algebras related to the exceptional Lie groups E7 are constructed using the quaternions (and the 8-component octonions) [5], which have been used by El Nas/chie to investigate E(&infty;) theory [8,9].

The existence of that journal would be one of the strongest arguments against publishing in Elsevier journals, if it weren't for the arms fairs and outrageous prices to provide even stronger arguments.

...But this time Elsevier Australia went the whole hog: they gave Merck an entire publication to themselves, which looked like an academic journal, but in fact only contained reprinted articles, or summaries of other articles. In issue 2, for example, 9 of the 29 articles were about Vioxx, and 12 of the remaining were about another Merck drug, Fosamax. All of these articles presented positive conclusions, and some were bizarre: like a review article containing just 2 references.

In a statement to The Scientist magazine, Elsevier initially said that the company "does not today consider a compilation of reprinted articles a 'Journal'". I would like to expand on this statement. It was a collection of academic journal articles, published by the academic journal publisher Elsevier, in an academic journal shaped package. Perhaps if it wasn't an academic journal they could have made this clearer in the title which, I should have mentioned, was: The Australasian Journal of Bone and Joint Medicine...

Whoops, didn't read the crackpot cites; at least the mappings that generate the images are clearly stated. Quick googling does not turn up even self-similarity for the pretty quaternion Julia set, so who knows if it's fractal.

Elsevier is indeed rapacious

Since this thread looks dead, I'll jack it- Does this seem extreme for an agreement that has to be signed to register a 5 year old for a basketball class? It seems to be saying I'm agreeing not to sue even if an instructor intentionally takes a tire iron to my kid and the director says, "No, hit him more to the left:"

IN CONSIDERATION, of being permitted to utilize the facilities, services, and programs of the YMCA for any purpose, including, but not limited to observation or use of facilities or equipment, or participation in any off-site program affiliated with the YMCA, the undersigned, for himself or herself and any personal representatives, heirs, children and next of kin, hereby acknowledges, agrees and represents that he or she releases the YMCA and its staff members from all liability for any injury, loss or damage connected in any way whatsoever to participation in YMCA activities whether on or off the YMCA's premises. He or she understands that this release includes any claims based on negligence, action, or inaction of the YMCA, its staff, directors, members and guests.

The "includes any claims based on negligence, action, or inaction" part is what gets me. Of course, we already did swim classes there previously and I guess my wife signed the form then, and there were no adverse tire iron incidents in the pool.

39: You may know this already, but Romanesco is actually a variety of cauliflower, not broccoli, despite the name. They are indeed trippy. You can see the same fractal patterns in plain old white cauliflower, they're just much more subtle.

I realize that what remains of the thread has turned to broccoli, but I have to confess (knowing I will be mocked for my earnestness) that I think these structures we all see while hallucinating (and I think we all see the same ones) have some deep relation to pattern recognition and the way we find meaning. It is most frustrating that I can't hope to describe verbally or mathematically what I find so achingly beautiful.

Seeing that there are a bunch of veteran hallucinogen takers here, a question: I once smoked a joint that must have been laced with something. About fifteen minutes or so after smoking it I got a brief but very intense headache with my vision going black. The headache disappeared and I got a kaleidoscope in front of my eyes - no sight whatsoever, just a bunch of swirling color patterns. About forty five minutes or an hour later the brief nasty headache returned, soon followed by my vision. Not much of a high, though that may be partly due to fear fueled adrenaline, I was with non drug taking people I barely knew, in a bar and was just a tad worried about how I would get home. But I've been wondering ever since, what the hell was it? Don't know if this matters but this was a hash/tobacco mix.

Speaking as a not-veteran hallucinogen taker, but having watched a bunch of other people, I'm not quite following. A mix of hash and tobacco might just do what you described especially if it was untreated raw tabacco: a big-time nicotine rush followed by the hash kicking in. I do recall it being popular to lace marijuana with pcp, unannounced, back in the day. (Which was a reason to avoid the stuff.)

Anyways, is there no love for Sierpinski tetrahedrons and Menger sponges (or really large, but the first render is prettier)?
