I guess that explains why I no longer have help fixing the shoes.
Okay, okay, I admit it, those images are totally freakin' trippy, and one of them is now my desktop background. Are you happy now, stoners?
Doesn't LB make this one in her spare time?
5: I was thinking exactly that -- those are totally crochet stitches.
5: That really looks like you are peering up the skirt of someone wearing elaborately crocheted tights. The legs come at you on either side, the thing across the top is a miniskirt, and in the darkness you wonder if she is wearing split panties.
Look at this! Look at this!! Do what we are doing! Do it! Do it! Do it! That's it! That's it! Keep doing it!
Deja vu!
7: The image is actually lifted from www.upskirtents.com .
JRoth, I couldn't help of think of you every time I stood up on my bike today (I am forever forgetting to downshift when I get to a light and thus have to stand to muster up more power when starting again). It's weird how imaginary internet people invade your mind.
The Mandelbulb is kind of lame. Though 15-year-old me probably would have been enthusiastic.
#7. Describe to me in single words only the good things that come into your mind about your mother.
(I've never met the machine elves. I have met the frog people. Not pleasant.)
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.
Ooh, I bet something fun can be done with the Heisenberg group.
Or not. Since I couldn't think up anything better in the course of an hour, I'll retract my accusation of lameness.
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 do math near this stuff.
Is your office in the Mystery Cave?
Saying "uh-oh" after the fashion of Scooby-Doo is banned!
As you were.
17: There's actually a lot of stuff out there connecting them.
Heebie you should post about the math you do. A cohomology primer, something like that.
Some hippie schools teach math to elementary kids through knitting (at least partially).
Also.
Well, now that I read it I see that the first link in 22 doesn't really show what I was hoping. I might look for another, later.
Also not entirely on point, but close enough.
dude! duude! that's totally it! except also made of the ordinary objects in your visual field in some way. some magical way.
3-D projections of quaternion fractals. images and references and video. Less contorted mathematically, though less freaky looking.
I have not read about even the basic properties of the quaternion mappings.
21: No, because my (legitimate) fear is that I wouldn't be able remember any nouns of any of the material, and I would come off sounding incompetent and it would turn out you all knew more than me all along.
I have not read about even the basic properties of the quaternion mappings.
Slacker! And you call yourself and Unfoddetariatdetarian.
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].
Google-proofed to prevent sock puppets from wandering over and threatening lawsuits.
"Quaternions came from Hamilton after his really good work had been done; and, though beautifully ingenious, have been an unmixed evil to those who have touched them in any way, including Clerk Maxwell." -- Lord Kelvin, 1892.
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
I thought about using our map printer at work to make a poster of some of those, but your jaded responses have dampened my interest.
31-33: Elsevier isn't alone in doing this. I've been offered the opportunity to develop something like this by a number of publishers (in my capacity as a mar comm guy for med device companies).
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:"

Got a Romanesco broccoli a couple of years ago in my CSA share, and brought it into work for Halloween... had never seen or heard of it before, and couldn't believe it was a fractal vegetable!
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.
Huh. I had seen those, but I never knew what they were called.
No, I didn't know that, thanks! It did taste more like cauliflower, come to think of it. (Roasted w. olive oil, salt, pepper.) What a trippy vegetable! I challenged everyone who came in that dayt to tell me what it was, and no one could identify it. The UPS guy quipped, "Some space-age weapon?"
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.
hat I think these structures we all see while hallucinating (and I think we all see the same ones)
Purple and yellow paisley?
45: 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)?
max
['It's only the groovy fractals-while-high thing, isn't it?']
43: well, they certainly have a deep connection to the way sensory information is processed in the brain.
That fractal vegetable is bizarre. I don't think I could eat it unless it had lost its integrity by steaming or boiling.
46: I was referring less to the geometric patterns one sees while on drugs like LSD, and more the entire experience.
48: Yeah, I was kind of thinking of those papers where researchers try and link visual hallucinations to information processing in the early visual cortex.
-2d4 SAN on first encounter. Just sayin.
