    Kuranes' Technology Thread

    I've created this so that I don't have to try to sift through a general thread like "Little raves" in case I want to find these linked articles again later.

    Interesting directed audio -

    Are other people allowed to post in your technology thread? Or is this more of a blog of things?
    We didn't land on Plymouth Rock. Plymouth Rock landed on us.

    David Wong, regarding Chicago
    Six centuries ago, the pre-Colombian natives who settled here named this region with a word which in their language means "the Mouth of Shadow". Later, the Iroquois who showed up and inexplicably slaughtered every man, woman and child renamed it "Seriously, Fuck that Place". When French explorer Jacques Marquette passed through the area he marked his map with a drawing of a brownish blob emerging from between the Devil's buttocks.

    Let's just skip to the good stuff, because everyone wants to see a Wooly Mammoth at a zoo.

    I saw this sound spotlight idea (I can't remember if they called it that or if that's just how it stuck in my head) debuted up at MIT (Media Lab, I think) a decade and a half ago. I don't know where they went with that, but I didn't see them mentioned in the article. Maybe it was a different approach to the problem.

    I didn't realize that the beginnings of projects to de-exctinct species are happening now. An excellent article from the New York Times.

    This quote grabbed me.

    The environmental and conservation movements have mired themselves in a tragic view of life. The return of the passenger pigeon could shake them out of it and invite them to embrace prudent biotechnology as a Green tool instead of menace in this century. . . . I would gladly set up a nonprofit to fund the passenger pigeon revival. .

    You can post here re: ^^ tech if you like. I was planning ( originally ) for it to mostly be a way for me to keep track of interesting tidbits I find in the news. They are new TO ME. If they are not new to you, and that is all you have to post here, please refrain.

    Peter Shor's allgorithm and its possible significance - http://en.wikipedia.org/wiki/Shor%27s_algorithm

    I enjoyed an article I read recently about David Deutsche, by Rivka Galchen, in a Michio Kaku anthology of notble science writin. Deutsche was one of the pioneers ( conceptually ) of Quantum Computing. An associate of his, Artur Ekert, is known for being more of a pioneer on the "making them a reality" end of things. Other interesting people were also referenced.

    The subjects of "Quantum entanglement" and "the many universes theory" also came up. Indeed Deutsche was thinking of some of these other things when he came up with the idea of the Quantum Computer, more as an afterthought.

    The idea of being able to factor large primes, and thus break the basis of security such as RSA's was considered too considerable of a task before this algorithm came along that would be an app for a quantum computer. Now that it has come along, Deutsche finds it compelling evidence for the "many universes theory".

    I quote Mr. Deutsche, from the article "When we run such an algorithm, countless instances of us are also running it in other universes. The computer then differentiates some of those universes ( by creating a superposition ) and as a result they perform part of the computation on a huge variety of different inputs. Later, these values affect each other, and thereby all contribute to the final answer, in just such a way that the same answer appears in all the universes." .....

    He goes on to say: "...To those who still cling to the single universe worldview, I issue this challenge: explain how Shor's algorithm works. I do not merely mean predict that it will work, which is merely a matter of solving a few uncontroversial equations. I mean provide an explanation. When Shor's algorithm has factorized a number using 10 to the 500th power or so times the computational resources than can be seen to be present, where was the number factorized ? There are only about 10 to the 80th power of atoms in the entire visible universe; an utterly miniscule number compared with 10 to the 500th power. So, if the visible universe were the extent of physical reality, physical reality would not even remotely contain the resources required to factorize such a large number. Who did factorize it, then ? How and where was the computation performed ?"

    He went on to say that this explained entanglement and "communication" at faster than light speeds, because of this inter-universe connection.

    Other gems from the article - paraphrased in some cases or quotes from Galchen vs. Deutsche, himself.

    1. Freud - "True ambivalence is not feeling unsure, but instead feeling opposit extremes of conviction at once." Just as ambivalence holds more information than a single emotion, so does a Qubit.

    2. If one reads quantum mechanical equations literally, superposition is ontological and not epistemological. The {Schrodinger} cat really is in both states at once.

    3. A Quantum computer is the pot that, if watched, really won't boil. The act of being observed forces Qubits to disentangle or commit to being a Schrodinger dead cat or live cat. ( This is the so-called "collapse".

    1.

    From an article in a magazine on Autism Spectrum -

    Two forms of aPKC ( the long one or the truncated one ) apparently compete to bind with Par3 protein in a developing ( mammalian is assumed at the very least ) brain. If there is not enough of the short one's successes than the result is too many axons and not enough dendrites. If there is not enough long forms succeeding in this binding then the result is too many dendrites and not enough axons. ( Assumption - brain communication is largely dependent on similar quantities of axons and dendrites forming, because they attach to one another in order to network. )

    So, based on this new observation, it is theorized that such imbalances may contribute to autism. The article did not elaborate on why there are sometimes statistically unusual failures in averages / results of the binding competition.

    The article briefly described what the status quo theory had been as to what happens re: axon dendrite distribution, prior to this new observation. It was summed up in a terse sentence and unfortunately I didn't write it down.

    2. Big tangent - but still re: brains.

    Loose wild talk about Area 51 scientists having access to large quantities of the newly discovered element 115. So far ( outside of this highly speculative trove ) only a few atoms of this have been made, which were very unstable and so disappeared quickly.

    If it were true ( invitation to speculate ) how would large quantities of such a material be useful - based on what little we know of its properties ? I looked it up on Wikipedia, and Wikipedia speculated that other new little-understood elements might be more stable, if we could figure out how to make them . So maybe they got the element number wrong.
