Years ago I watched a documentary about weird math mysteries and there was one bit about patterns emerging from seemingly random systems. One of them, called Langton's ant, consisted of a virtual ant on an infinite grid. The rules were simple, and IIRC, they went something like this: the ant begins on an all-white grid. Moving forward one space, if it enters a white square, the square turns black and the ant makes a right turn and moves forward one square. If the ant encounters a square that is already black it turns right andoves forward. The ant proceeds to move very chaotically until suddenly, at around 5000 moves, it falls into a repeating pattern that it never escapes from. This blew my mind all those years ago and I still wonder why the hell the pattern emerges from the chaos. Obviously, it's not actually chaos since there are rules that the ant follows and it's probably those constraints that give rise to the pattern, but then why does it take 5000-odd moves for the pattern to crop up? Is there some additional rule that can let the ant avoid the trap and continue moving randomly?

Someone here probably has this thing figured out, right?

so im having relatively high arches like in pic related. now i want to buy myself some high heels, but the problem is, when i step the heel comes off. i dont know why. i want you to help me figuering out the physical leverage, so that i can buy online successfully.
please explain the physics so that i understand why the heel comes off and so that i can estimate wether the shoe will fit.

thank you for replying!

when i take a step i put the (high) heel first down, then i shift my weight to the metatarsal and when i roll onto the ball of my feet and lift the high heel off the ground, thats when the heel strap comes off.or, in the case of the blue shoes, my heel itself lifts off the cap. so like the moment of demi pointe like pic related, the heel is almost vertically in line with the ball of my foot, and i still dont get it which straps need to be in order that the inner sole sticks somewhat close. so i just assume its the mobility in ankle that needs a strap but its so weird, because i tried a modell similar to the red one only with thinner curved strap and heel came off. i think its like a redirection of forces and basically same pattern but just different placement of straps, im confused which placement i should go for.please shed some light.

I've created a system for roulette that of course is not a 100% certain profit over time, but depending on your starting bankroll, the odds can be a fraction of a percent.

Essentially on my system I place 8 chips on the final 3rd section, so if the ball lands here I will get my exact money back (3 to 1)

Including 0 that leaves 25 numbers. I cover 11 of those with a few split bets too. The strategy is that if I miss a final 3rd or my numbers, I double the bet. If I hit a number that is not in the final 3rd, go back to the starting bet which in total is $6 with $0.25 chips. If I get a final 3rd result (the 3 to 1) I repeat the bet whatever the amount.

So we can negate the final 3rd section and set the odds to 11/25 as a win, however it depends on your starting balance. If I start with $6 and miss I double to $12, miss again double to $24 and so on. The odds of say missing a 11/25 spin 6 times in a row is what? I don't actually know which is why I am here, but I think it's 2. something.. Anyway, you can see that if you have say $11,000 you can make money on this method easily. I play on live tables and not computer generated games. I often play up to a double of $192, which as a total of all losses plus the 192 is $380 plus. When I get $200 profit I leave and cash out the profit.

So with this 5G coming up we're hitting a new wave of protests, meetings etc etc about the alleged dangers of all kinds of microwaves, and I noticed a lot of people around me are absolutely convinced wifi, cellphones and even microwave ovens are horrible for their health.

I'm not well versed on the subject of the effects of certain wave lengths, but aren't all wavelengths we use in the modern world non-ionizing and incapable of causing cancers? Are there any real reasons to be afraid or is it just people being afraid of things they do not understand?

>Numerous recent scientific publications have shown that EMF affects living organisms at levels well below most international and national guidelines. Effects include increased cancer risk, cellular stress, increase in harmful free radicals, genetic damages, structural and functional changes of the reproductive system, learning and memory deficits, neurological disorders, and negative impacts on general well-being in humans. Damage goes well beyond the human race, as there is growing evidence of harmful effects to both plant and animal life.
>Nevertheless, they showed a modest increase in the intracellular level of IL-1b, a major pro inflammatory CYTOKINE produced and release by keratinocytes in response to various stimuli [62]. This result suggests that 61.2-GHz exposure could activate keratinocytes. Moreover, the in vivo study of Makar et al. [63, 64] on mice irradiated at 61.3 GHz and 31 mW/cm2 also showed a pro-inflammatory effect initiated by activation of free nerve endings in the skin.

this is the troubling thing, because at this frequency oxygen ionizes. when this happens, hemoglobin in your blood cannot bond to oxygen, meaning you suffocate until you die from a lung attack, multiple organ failure, and hypoxic encephalopathy, even if you are on oxygen. but as was provided earlier, you don't have to reach 60ghz to have adverse effects. they happen right now at existing 3g and 4g levels. it's no longer a layman's opinion.

If you read the manual on your cellphone, it tells you don't talk on your cellphone by holding it to your ear. That's because cellphones exceed the FCC max exposure limits when it's that close. Non-ionizing radiation is capable of doing harm. FCC limits are based off thermal effects. There are a few studies that have shown non-thermal effects. It's an understudied part of science.

The big advantage of the higher frequencies is antennas can produce more gain and directivity at the same size. This can lead to higher ERP(effective radiated power). ERP if a big factor when doing RF exposure calculations. For example if your transmitter is putting 10W in to a phased array antenna that's forming a beam in your phone's direction with 40dB gain, you're on the receiving end of an effective 100kW compared to an omnidirectional antenna. So is anyone who is on the same line as you from the antenna. The effects of that depend greatly on distance and the unstudied nonthermal effects of RF.

The one provable result of this directivity is even more loss of privacy. A 40dB antennas beam is incredibly thin so the beamforming algorithm has to know a lot about your location. If you think they're not putting that info to other uses, I envy you.

bioprocessing and nanoprocessing facilities ensure that each megacity deck is entirely self sufficient. barring contributions from automation, this process requires no imports once sufficient manpower is in place. the only real consumables, fresh air and water, can be rectified using these facilities. the secret to progressing these technologies to the point where we create super materials actually involves a secret that I wouldn't give away here. however even if you knew what to do with nanotechnology to make it past, and into what is beyond it, you would still have to get the source material from somewhere.

existing nanotechnology doesn't print out of thin air, you need a reservoir of atoms to begin stacking. post-nanotechnology uses existing nanotechnology to create radioactive nanotextile catalysts, which are subjected to extremely specific conditions in order to secrete the building blocks for free. yes, you read that right. push a button, print molecularly perfect steel for free. having the secret to this process technology allows a breakaway civilization to happen, because we no longer need to cut down trees for lumber, mine the earth for ore. we can synthesize everything we need.

the cost of doing all of this is 100% meaningless because the process technology in question has already been proofed and there is nothing you can do about it. the team we are looking to build will be able to print composites out of subatomic particles, composites which are non atomic and therefore have literally incalculable properties and which cannot be dissolved. no one else can manufacture these composites, or design them, or build the machines for them,
or get them to print for free using a catalyst. a solar boiler powers the laboratory. the companies that invest on this project will rule the universe. we won't have to ask for financing. we will be able to create shields that can block bullets, beams that can hold entire cities, and if you tried to bring a material sample into a metrology laboratory you'd be saddened to find that imagine equipment to discern the true nature of the material does not exist.

it would be like looking at metal from roswell. non atomic matter that is seemingly weightless but also impenetrable. the more you look at it the wilder it gets. But wait, there's more.

of course we won't get the final MegaCity drawn out without prototypes, and that's actually where the scale-up to the final product comes in: agriculture and livestock. Livestock and agriculture use up unbelievable amounts of land. from global agriculture dot org:
>Livestock is the world's largest user of land resources, with pasture and arable land dedicated to the production of feed representing almost 80% of the total agricultural land. One-third of global arable land is used to grow feed, while 26% of the Earth's ice-free terrestrial surface is used for grazing.
animal rights activists have already pointed out that we keep a lot of these animals, billions of them, stacked up on top of each other in cages so small their legs stick out. it's like a homeless pig wearing a cardboard box for clothes, but it's a metal cage, packed tight in an endless hamstrung abyss. if that's how we are going to treat them, like shit, then why can't we take all that bullshit and stack it up on top of itself? we can use both agriculture and livestock to proof the megacity construction process and get it established. the world is already fighting over food, and honestly even pitching this idea to a chinese megafarm corporation would get it built in 10 years.

We can do better than that, under budget and ahead of schedule, where it counts. the same materials science will allow for hypertransport projects such as high speed rail between megacities. as we use less and less roads, we will save lots of land for the biome just from taking the commerce off the land, let alone the people and animals. as the conservation land increases by orders of magnitudes, until the whole nation is a wildlife preserve and we begin creating rainforests in earnest, the job sectors related to conservation will grow exponentially. we will need biologists, wildlife experts, botanists, rangers. withing just a few years, locally, the forrest around the megacity could easily become wild and these habitats will need to be scientifically managed into the future, even passively, in the same way we manage these habitats now.

The first civilian megacity will be called Rome, and it will be shaped like a Starfort. those are my only two conditions as the sole designer & owner of the pseudo-gap nanocatalyst process technology.

science however will not stop with the advent of megacities, instead it will continue into the stars as we map out other elemental systems of power besides solar and electricity, and thermal. we will also explore sonic technology, which is already used in sub micron machine tooling processes, and plasma modulation, which has the potential to take us into a new epoch of transistor and circuit design by transcending the electrical systems we have today for optical plasma based transistors with a gap size and frequency, combined, which approach luminal speeds and in the case of specialized pseudo gap jumping can actually exceed that boundary into superluminal performance (the distance the flame jumps multiplied by the frequency exceeds C). combined with subnanotechnology, these embedded optical circuits could never be reverse engineered or hacked. the computational capabilities of these future systems are science fiction today. tomorrow the exports from the megacities will dominate all commerce. as we expand out into the solar system, having finally breached the technology necessary to do the impossible we will be able to build megacities in space terrariums and leave the earth relatively alone, as the cradle it was meant to be.

Yup. That's one simple cellular automata. It was the first, and it's what got Wolfram started on his CA research.

> this sounds similar to fractal mysticism to me,
Kinda, I haven't read OP's link yet, but Wolfram has been saying the same thing for about a decade about these systems. And while it's really fascinating how he can explain pretty much any phenomenon as automata, it's not at all surprising. Why? Because this:

>Start with a very basic seed pattern or equation or the like, apply some simple rules and (here's the kicker) iterate on that to infinity and viola! Out pops something infinitely complex and super cool looking.
Yes. You're describing how a lot of fractals are made. But it's also how many physics simulations are done. You're also kind of explaining what a 'turing machine' is.

Think of a "turing machine" as a fancy way of saying "something that can function as a computer."

Now, a "turing complete machine" is a turing machine which, if given enough memory and time, can calculate the state of any other turing machine.

Cellular Automata ARE turing complete machines. Anything that a computer can theoretically calculate, a CA can calculate.Because of this equality among turing complete machines, it's a bit weird that Wolfram places automata as the one model to rule them all.

At least that's the criticism of Wolfram that I read a long time ago. Personally, I think CA are awesome, and I'll definitely read OP's link later.

Iff Wolfram's turing machine can predict even one scientific breakthrough then it will be the most amazing thing in the world, and knowing that there are thousands of the world's top minds going after this prize, I shall sit here and wait patiently for that to happen.

I think these graphs are a model of our own way of thinking, in reverse. We started out by becoming self-aware in a chaotic environment of infinite complexity, so we invented things like philosophy and religion to try and make some sense out of it. Then we honed our understanding down to a scientific method. The way we make sense of things in general is to try and model it with abstraction. We try and break things down to their simplest form, because simple things are easier to understand. We took the top-down approach over millenia of careful observation, where these graphs and rules of Wolfram's theory are going in the other direction. Start out with something extremely simple, mix in something special (the theoretical key to the universe) and let the computers see if you were right. Sorry, I'm still trying to wrap my head around how this is going to lead to a reliable scientific breakthrough, but I'm not writing it off as impossible as of yet.

the thing with this fractal mysticism is that no scholastic authors would touch the 'schizo LSD theory' until after Nassim's paper won awards. It's the same shape that buckminster fuller discovered, and you could use almost any vector matrix to pull all this off. Some physicists are working with a shape called m0, or Mzero, which is really an infinite fractal of circles. obviously the simples solution is the best solution, but mainstream science won't touch that solution. gives them the heebie jeebies, and inside that shape as it moves we find almost all the shapes from every major religion, like jigsaw pieces.

that's too far out for them. they are desperately searching for any shape that can pull it off, but it's never going to be computationally efficient compared to the real thing, which is a platonic solid with 4 platonic vectors it can translate and recurse across. It's potential is practically limitless and will redefine math forever, but it's too religious for them.

if they fail to adopt it, then their science will fall behind compared to any faction that can put their ego aside long enough to use it. that faction will create a breakaway civilization in short order.

I'm afraid no. Think about for long long alcohol has been around. If there would be some easier way, people would've figured it out by now (remember we had the prohibition and the immediate post-war era in Europe).
There are several routes you can take, all of them are very rough and not feasible in your basement:

  • Reduction of acetic acid or acetaldehyde (sodium hydride)
  • Oxidation of ethylene (oxygen + catalyst + pressure)
  • Basic hydrolysis of ethyl esters (sodium hydroxide)

You won't get around fermentation. Just ferment some paper like NileRed did and distill to 98 Vol.-%. You can quench the remaining water either by using a molecular sieve, by addition of acetic anhydride or by adding a decent amount of sodium sulfate and subsequent filtration.

You could also just try and distill vodka I guess lol

if i get an inflatable house tent and fill it with sea water is it gonna be insulating? could reinforce it with easy to source bamboo too. so if it insulates good its a cheap house.
does an inflatable filled with air insulate more then a nromal tent thats just fabric or some shit? i dunno.
i wanna buy a military style tent thats fabric and buy land and have a cheap de-constructable house while i build one out of wood or something is why im asking this and why i want to live in a tent. but i've camped before and inside the tent was cold as hell, with a sleeping bag. i don't camp in tents year round though so i don't know how sleeping in a tent is. i've slept in a tent at some years and it wasn't as cold as i remember but at that time of year it isn't cold at all i don't think.
