  1. Re:Savants on Bigger Brains Make Smarter People Study Says · · Score: 1

    It is more likely the number of folds in the brain that predict intelligence, since folds imply a more complex wiring pattern.

    Probably more the depth of the folds than their number. The folding pattern is pretty constant. Increasing depth of folding produces both increasing surface area and reduced connection length among some structures.

    The brain tissue is organized into layers of neurons, with something like just a half-dozen on the top being responsible for most of the processing. So the more surface area the more neurons and the more interconnections between them.

    Folding allows a much larger surface area in a given volume (imagine how big the head would be if the brain were a sphere of the same surface area). It also shortens any interconnections between distant sections that go directly rather than following the surface (cutting signal transit time).

  4. Not unless they fab brainwashing nanomachines... on Fab · · Score: 4, Interesting

    It's pretty much inevitable that evildoers will acquire this technology, but Gershenfeld is optimistic that fab labs can help address the root causes for conflict, largely assuaging any threat.

    I'm afraid that's a pretty materialistic analysis - assuming scarcity of goods is the root of all conflict - and it misses at least two other root causes that are not easily addressed by improved production.

    The first is psychopathy. About 1% of the human race has a mental defect that amounts to having no conscience. Think "color blindness", but with moral behavior / internalizing others' pain, rather than color. (Another couple percent learn to act as if they have no conscience, but that's a social/upbringing issue.)

    A large fraction of these people don't learn how to compensate, and a lot of those don't think ahead to long-term consequences to themselves from their actions. Such people will do whatever pleases them, which includes such things as creating a new virus (computer style or molecular, depending on available technology) just to see how much havoc it can cause.

    Improving production won't address this root cause. Indeed, to address it directly may require brain surgery or its nanotechnological equivalent. This may be within the scope of the fabrication technology. But deploying technology to rewrite peoples' brains in order to suppress a class of destructive behavior starts down a very slippery slope.

    A second is ideological: Adherence to a belief system (especially a political and/or religious belief system) allowing, or even prescribing, the initiation of deadly force in response in various situations.

    If such a situation is perceived, the adherent with access to such technology may utilize it to create the deadly force. And in a classic case of asymmetric warfare, empowering individuals simply increases the ability of small numbers of people to create large amounts of damage. (Examples: Adherents to a confused splinter of such an ideology, mainstreamers who have perceived a threat where none existed, or mainstreamers who perceived an ACTUAL threat and overreacted).

    "Addressing" this "root cause" would again involve attempting to modify peoples' mindsets. And most such ideologies include, at the top of the list of situations where deadly force is mandated, attempts to suppress the ideology. "Addressing the root cause" creates the very apocalypse you're trying to prevent.

    This is not to say that the technology should be suppressed: On the contrary. It holds enormous promist for actually eliminating the root causes of many sorts of conflict. And it may be enabling for real solutions that would demotivate some of these hard cases. Cheaper resources are generally good for problem solving, making more solutions accessable.

    But counting on it to "address", or even "help address", ALL the "root causes of conflict", IMHO, expects too much from it. Some of these will need solutions that don't come out of fabrication technology.

    - The standards document itself is copyright, but
    - The code as adopted (including the expansion of references into the full text itself) was law and as such not subject to copyright claims, so
    - The code as adopted, even if it includes the full text of the standards document verbatim, is public domain, and
    - The standards organization, by proposing the standard to be adopted into law, agreed to this (even if they obviously didn't intend to, as evidenced by their business model and suit), and thus
    - Publishing the code as adopted by some US jurisdication - correctly annotated as such - does not violate the copyright on the standard (even if it includes the whole text of the standard).

    Story circulating in the '60s is that extremely overheated teflon depolymerizes back into TFE, which is EXTREMELY toxic. (And that slivers of teflon in a cigarette had been used as a murder weapon.)

    Story circulating the chemestry department at the same time was about the discovery (not invention) of teflon:

    Pair of scientists were doing work with TFE. They had set up their equipment, hooked up the gas bottle with the TFE in it, and opened the valve.

    Nothing happened.

    They weighed the bottle. Not empty.

    So they took their lives in their hands and first opened the valve with nothing attached (no gas, which is good because if there had been they'd have been dead) then cut the bottle open (white powder, which is good because if the valve had been stuck and the tank full of gas they'd have been dead).

    They realized that some impurity had gotten into the bottle and polymerized the TFE - and had a small amount of the polymer to play with to check that it really WAS poly-TFE and discover interesting properties.

    Once they knew that polymerizing TFE could be done, it was only a short time before they figured out how to do it, first in the lab, then on an industrial scale.

  8. Are you aware that "buckyballs" are "soot"? on Nanotech Protests Begin · · Score: 3, Informative

    I have heard a bit about how the BuckyBall carbon molecules don't break down and react strangely with the body. So nano tech is hardly inert. The BuckyBall issue, while made from simple carbon, is a different shaped molecule. And could result in another health issue like asbestos fibers.

    Are you aware that buckyballs are a major component of soot? Along with many of the other carbon nanostructures (many of which are manufactured by sorting them out of soot).

    Humans have had a very long time to evolve defenses against these particular carbon compounds that "react strangely" with the body - along with a lot of other combustion products.

    One of the dioxins, for instance, is a low-grade carcinogen for humans, instant death for birds (as in they literally fall out of the sky, which is how a chem prof told me at least one accidental release was detected) at similar concentrations, and extremely toxic for just about all other animal life.

    That would have been funny if you'd said "to our neighbors in Georga". Instead you repeated and reenforced a racial and ethnic stereotype: That (all) white southerners are all racists. This ruined the joke for a lot of your readers.

    I'm inclined to assume - THIS time - that it was ignorance rather than hatred-driven intent that led to this faux pas. But please be aware of how such statements might affect others - and that the same pun is available in a non-painful form.

    By the way: If you're living in a subculture where that meaning of "cracker" is more common than the alternative I suggested, the people around you have probably set you up for the same problem with "redneck".

    A "redneck" - as used by rednecks themselves - is a person who works outdoors, typically in a rural setting, typically with short hair, typically with ancestry predominantly white, indian, or a mix. It refers to the skin tone - sunburn or red undetne on the back of the neck. It does not have the connotaton of "moron" or "racist", and in fact real rednecks are actually of (at least) the normal range of intelligence (with plenty of high-achievement geniuses) and average far LESS racist than the inhabitants of the coastal urban areas. (For starters, the bulk of the actual rocket scientists on the moon shot were rednecks.)

    The "racist moron" stereotype was initially promulgated by the eastern coal companies during the start of unionization. (They also made a big point of how these people were allegedly "mongrels", i.e. racially mixed - European, Indian, and African.) It was no accident that Darrow and Scopes were both hired by a mine manager to break the local religion, which supported the unions and provided a place where workers could meet to organize with little fear of attack by the companies' mercenary thugs. The remains of this propaganda campaign still hang over in the culture of US eastern cities and thus in the US media.

    But why bother when digital is so much more precise?

    Because quantiztion and roundoff error play HELL with derivatives. Bigger, faster, cheaper digital computers had to be developed and better algorithms discovered before digital could take over the job. Once that had been done, digital's flexibility won out.

    Analog computer technology was an outgrowth of audio and radio, and developed quickly during and immediately after WW II. A couple dozen components would make the fundamental building block, which could do an accurate computation (weighted sum, integration, differentiation, or something more complex) at kilohertz to megahertz rates. A similar number of components, as a digital device, could make a couple flip-flops processing a bit at about the rate the op-amp could do the entire computation. Noise and offset could be controlled, and taken into account. (In a feedback system, as in the real-world device being modeled, offset and noise are suppressed by the feedback if the system is stable.)

    Analog computational technology is STILL in heavy use - at high frequencies, and at the edges of digital systems. (Digital techniques are just starting to take over some of the functions of, for instance, radios.)

    The main reason digital wins out is that the computational elements are sufficiently immune to noise that they can be miniatureized and placed close together without misbehaving. When you get enough orders of magnitude cost reduction from that, you can throw enough of them at an analog problem to get an acceptable answer for less money and engineer time than you'd need to spend doing it with purpose-built or purpose-wired analog parts. Then digital wins.

    There are not 'morphing' connections, they tend to mostly stabilize within the first few years of life.

    Sorry, that's wrong. It has recently been discovered that neurons are constantly growing and reabsorbing a fuzz of little proto-connections (whose name I can't recall just now) to adjacent neurons. Under some circumstances (presumed to be related to correlations between the firing times of the neuron with the fuzz and the neuron a fuzz hair is approaching) one of these hairs makes a connection and fattens up into a full-blown connection (presumably to reenforce and shortcut the processing).

    Of course that's necessarily only a part of the story. There'd have to be a mechanism cutting the connections (or you'd eventually end up with a mess capable mostly of epileptic fits and squeezing out its own circulation).

    It has also been discovered that the astrocytes in the brain are stem cells which actually spawn new, functioning, interconnecting-with-the-rest, neurons - far into old age, even in humans.

    (Brain cell replacement in adults was not totally surprising. It has long been known that the portion of bird's brains responsible for mating calls actually grows considerably - by new cell production - as mating season approaches, and shrinks - by cell death - between seasons.)

    Again it is hardly surprising that new cell production would be slower in adulthood (when the machine is functioning well and has limited space - so must sacrifice something else if it is to grow much) than in infancy and childhood (when the machine is still under construction and learning is progressing rapidly).

    But these effects will certainly need to be taken into account in any accurate simulation. And they might not be just structural maintainence, but instead be fundamental to some of the processing functionality of the brain.
