RESHARED POST FROM JORDAN PEACOCK

The charts in the link are beautiful. http://io9.com/5911520/a-chart-that-reveals-how-science-fiction-futures-changed-over-time Jordan Peacock originally shared this post: A Chart that Reveals How Science Fiction Futures Changed Over Time io9 In the 1900s and the 1980s, there were huge spikes in near-future science fiction. What do these eras have in common? Both were times of rapid technological change. In the 1900s you begin to see the widespread use of telephones, cameras, automobiles (the Model T came out in 1908), motion pictures, and home electricity. In the 1980s, the personal computer transformed people’s lives. In general, the future got closer at the end of the twentieth century. You can see a gradual trend in this chart where after the 1940s, near-future SF grows in popularity. Again, this might reflect rapid technological change and the fact that SF entered mainstream popular culture. The future is getting farther away from us right now. One of the only far-future narratives of the 1990s was Futurama. Then suddenly, in the 2000s, we saw a spike in far-future stories, many of them about posthuman, postsingular futures. It’s possible that during periods of extreme uncertainty about the future, as the 00s were in the wake of massive economic upheavals and 9/11, creators and audiences turn their eyes to the far future as a balm.

RESHARED POST FROM JON LAWHEAD

Jon Lawhead originally shared this post: This is Yaneer Bar-Yam’s “A Mathematical Theory of Strong Emergence Using Multi-Scale Variety.” It, along with the other paper of his I just posted, is going to turn out to be one of the most significant papers of the 21st century. I would bet money on it. Integrating the insight in these two papers into contemporary philosophy of science (and expanding on them) is one of the central pillars of my overall professional project. #complexitytheory is the next big scientific paradigm shift. All the pieces are out there now (these two papers are two of them); we just need to put them all together into a unified, coherent narrative. The first person/people to do that will go down in history as being the Darwin of the 21st century.

#COMPLEXITY SCIENTISTS ARE ALREADY WATERING…

#complexity scientists are already watering at the mouth for #exascale computing. This is a fabulous demonstration of what they can already do at petascale levels. From http://news.stanford.edu/news/2012/may/engineering-hypersonic-flight-051512.html One reason computational uncertainty quantification is a relatively new science is that, until recently, the necessary computer resources simply didn’t exist. “Some of our latest calculations run on 163,000 processors simultaneously,” Moin said. “I think they’re some of the largest calculations ever undertaken.” Thanks to its close relationship with the Department of Energy, however, the Stanford PSAAP team enjoys access to the massive computer facilities at the Lawrence Livermore, Los Alamos and Sandia national laboratories, where their largest and most complex simulations can be run. It takes specialized knowledge to get computers of this scale to perform effectively, however. “And that’s not something scientists and engineers should be worrying about,” said Alonso, which is why the collaboration between departments is critical. “Mechanical engineers and those of us in aeronautics and astronautics understand the flow and combustion physics of scramjet engines and the predictive tools. We need the computer scientists to help us figure out how to run these tests on these large computers,” he said. That need will only increase over the next decade as supercomputers move toward the exascale – computers with a million or more processors able to execute a quintillion calculations in a single second.

THIS ROBOT MAKES ITS OWN CUSTOM TOOLS OUT…

This Robot Makes Its Own Custom Tools Out of Glue At this point, you’ve probably noticed the similarities between this process and 3D printing, which is much faster and provides a lot more detail. The reason this robot can’t just 3D print a cup is that the thermoplastic materials don’t provide any good ways of bonding objects to the robot itself, which would mean that the robot would have complex manipulators and deal with grasping, and the whole point (or part of the point) of the HMA is to make complicated things like that unnecessary. While the actual execution of this task was performed autonomously by the robot, the planning was not, since the robot doesn’t yet have a perception process (or perception hardware, for that matter). This is something that the researchers will be working on in the future, and they fantasize about a robot that can adaptively extend its body how and when it deems fit. They also suggest that this technique could be used to create robots that can autonomously repair themselves, autonomously increase their own size and functionality, and even autonomously construct other robots out of movable HMA parts and integrated motors, all of which sounds like a surefire recipe for disaster if we’ve ever heard one.

THIS ROBOT MAKES POST FROM INFORMS

Very interesting! From the Wiki: http://en.wikipedia.org/wiki/Braess%27s_paradox The paradox is stated as follows: “For each point of a road network, let there be given the number of cars starting from it, and the destination of the cars. Under these conditions one wishes to estimate the distribution of traffic flow. Whether one street is preferable to another depends not only on the quality of the road, but also on the density of the flow. If every driver takes the path that looks most favorable to him, the resultant running times need not be minimal. Furthermore, it is indicated by an example that an extension of the road network may cause a redistribution of the traffic that results in longer individual running times.” The reason for this is that in a Nash equilibrium, drivers have no incentive to change their routes. If the system is not in a Nash equilibrium, selfish drivers must be able to improve their respective travel times by changing the routes they take. In the case of Braess’s paradox, drivers will continue to switch until they reach Nash equilibrium, despite the reduction in overall performance.

RESHARED POST FROM AMIRA NOTES

Amira notes originally shared this post: The Self Illusion: How the Brain Creates Identity “John Locke, the philosopher, who also argued that personal identity was really dependent on the autobiographical or episodic memories, and you are the sum of your memories, which, of course, is something that fractionates and fragments in various forms of dementia. (…) As we all know, memory is notoriously fallible. It’s not cast in stone. It’s not something that is stable. It’s constantly reshaping itself. So the fact that we have a multitude of unconscious processes which are generating this coherence of consciousness, which is the I experience, and the truth that our memories are very selective and ultimately corruptible, we tend to remember things which fit with our general characterization of what our self is. We tend to ignore all the information that is inconsistent. We have all these attribution biases. We have cognitive dissonance. The very thing psychology keeps telling us, that we have all these unconscious mechanisms that reframe information, to fit with a coherent story, then both the “I” and the “me”, to all intents and purposes, are generated narratives. The illusions I talk about often are this sense that there is an integrated individual, with a veridical notion of past. And there’s nothing at the center. We’re the product of the emergent property, I would argue, of the multitude of these processes that generate us. (…) The irrational superstitious behaviors : what I think religions do is they capitalize on a lot of inclinations that children have. Then I entered into a series of work, and my particular interest was this idea of essentialism and sacred objects and moral contamination.

Raymund Kho K.D. originally shared this post: #neuroscience #deception #lying #signal_dectection_theory deception and deception detecting, an evolutionary advantage a very informative article on the evolutionary aspects of deception and deception detection. currently it is possible to detect deception in near all cases in real-time. further i disagree the observation where the reported chronometric cues were replicated in relation to significant longer response latencies. a more modern example relates to the case of the infamous confidence-trickster, frank abagnale jr., who is now an fbi financial fraud consultant. those who employ former “poachers” assume that people who are good at breaking the law are good at detecting when others break the law. this assumption is widespread, but at least in the case of deception, there is no scientific evidence to suggest that good liars are necessarily good lie detectors. results indicate that the current paradigm is comparable to previous studies with regards to the participants’ self-reported experience of guilt, anxiety, and cognitive load during the task, and overall lie detection accuracy. In addition, previously reported chronometric cues to deception were replicated in this study, with significantly longer response latencies when lying than when telling the truth. moreover, as far as we are aware, this study is the first to provide evidence that the capacity to detect lies and the ability to deceive others are associated. this finding suggests the existence of a “deception-general” ability that may influence both “sides” of deceptive interactions. open for discussion. “You can’t kid a kidder”: association between production and detection of deception in an interactive deception task full article. “You can’t kid a kidder”: association between production and detection of deception in an interactive deception task Both the ability to deceive others, and the ability to detect deception, has long been proposed to confer an evolutionary advantage.

RESHARED POST FROM DERYA UNUTMAZ

Derya Unutmaz originally shared this post: A group of American researchers from MIT, Indiana University, and Tufts University, led by Erin Treacy Solovey, have developed Brainput — pronounced brain-put, not bra-input — a system that can detect when your brain is trying to multitask, and offload some of that workload to a computer. The idea of using computers to do our grunt work isn’t exactly new — without them, the internet wouldn’t exist, manufacturing would be a very different beast, and we’d all have to get a lot better at mental arithmetic. I would say that the development of cheap, general purpose computers over the last 50 years, and the freedoms they have granted us, is one of mankind’s most important advancements. Brainput is something else entirely though. Using functional near-infrared spectroscopy (fNIRS), which is basically a portable, poor man’s version of fMRI, Brainput measures the activity of your brain. This data is analyzed, and if Brainput detects that you’re multitasking, the software kicks in and helps you out. In the case of the Brainput research paper, Solovey and her team set up a maze with two remotely controlled robots. The operator, equipped with fNIRS headgear, has to navigate both robots through the maze simultaneously, constantly switching back and forth between them. When Brainput detects that the driver is multitasking, it tells the robots to use their own sensors to help with navigation. Overall, with Brainput turned on, operator performance improved — and yet they didn’t generally notice that the robots were partially autonomous.

RESHARED POST FROM WAYNE RADINSKY

” We all know that, for example, the iPad is assembled from lots of high tech suppliers. The piece below thinks about that in terms of the knowledge required to build an iPad. That knowledge is more than a single company can handle and it must be spread among a number of companies. In the early days, life was simple. We did important things like make spears and arrowheads. The amount of knowledge needed to make these items, however, was small enough that a single person could master their production. There was no need for a large division of labor and new knowledge was extremely precious. If you got new knowledge, you did not want to share it. After all, in a world where most knowledge can fit in someone’s head, stealing ideas is easy, and appropriating the value of the ideas you generate is hard. At some point, however, the amount of knowledge required to make things began to exceed the cognitive limit of a single human being. Things could only be done in teams, and sharing information among team members was required to build these complex items. Organizations were born as our social skills began to compensate for our limited cognitive skills. Society, however, kept on accruing more and more knowledge, and the cognitive limit of organizations, just like that of the spearmaker, was ultimately reached. … Today … most products are combinations of knowledge and intellectual property that resides in different organizations. Our world is less and less about the single pieces of intellectual property and more and more about the networks that help connect these pieces. The total stock of information used in these ecosystems exceeds the capacity of single organizations because doubling the size of huge organizations does not double the capacity of that organization […]

“INSPECTION FUNCTIONS CEASELESSLY. THE GAZE…

“Inspection functions ceaselessly. The gaze is alert everywhere: ‘A considerable body of militia, commanded by good officers and men of substance’, guards at the gates, at the town hall and in every quarter to ensure the prompt obedience of the people and the most absolute authority of the magistrates, ‘as also to observe all disorder, theft and extortion’. At each of the town gates there will be an observation post; at the end of each street sentinels. Every day, the intendant visits the quarter in his charge, inquires whether the syndics have carried out their tasks, whether the inhabitants have anything to complain of; they ‘observe their actions’. Every day, too, the syndic goes into the street for which he is responsible; stops before each house: gets all the inhabitants to appear at the windows (those who live overlooking the courtyard will be allocated a window looking onto the street at which no one but they may show themselves); he calls each of them by name; informs himself as to the state of each and every one of them – ‘in which respect the inhabitants will be compelled to speak the truth under pain of death’; if someone does not appear at the window, the syndic must ask why: ‘In this way he will find out easily enough whether dead or sick are being concealed.’ Everyone locked up in his cage, everyone at his window, answering to his name and showing himself when asked – it is the great review of the living and the dead.” Foucault, Panopticism http://foucault.info/documents/disciplineAndPunish/foucault.disciplineAndPunish.panOpticism.html _ More on the robot here: http://spectrum.ieee.org/automaton/robotics/military-robots/robocops-now-guarding-south-korean-prisons World’s First Robot Prison Guard

RESHARED POST FROM NEUROSCIENCE NEWS

“These experiments were performed by Christian Ethier, a post-doctoral fellow, and Emily Oby, a graduate student in neuroscience, both at the Feinberg School of Medicine. The researchers gave the monkeys a local anesthetic to block nerve activity at the elbow, causing temporary, painless paralysis of the hand. With the help of the special devices in the brain and the arm – together called a neuroprosthesis — the monkeys’ brain signals were used to control tiny electric currents delivered in less than 40 milliseconds to their muscles, causing them to contract, and allowing the monkeys to pick up the ball and complete the task nearly as well as they did before. “The monkey won’t use his hand perfectly, but there is a process of motor learning that we think is very similar to the process you go through when you learn to use a new computer mouse or a different tennis racquet. Things are different and you learn to adjust to them,” said Miller, also a professor of physiology and of physical medicine and rehabilitation at Feinberg and a Sensory Motor Performance Program lab chief at the Rehabilitation Institute of Chicago. Because the researchers computed the relationship between brain activity and muscle activity, the neuroprosthesis actually senses and interprets a variety of movements a monkey may want to make, theoretically enabling it to make a range of voluntary hand movements. “This gives the monkey voluntary control of his hand that is not possible with the current clinical prostheses,” Miller said.” Neuroscience News originally shared this post: New Brain-Machine Interface Moves a Paralyzed Hand New technology bypasses spinal cord and delivers electrical signals from brain directly to muscles.

Perhaps the comment below will orient the discussion a bit better; the table below may help. You can find links to the attention economy series to date at the end of this post.

I’ve got my work cut out for me. =) The most important thing I want to say, if I haven’t been clear, is that the flow of attention is a self-organized phenomenon, with each individual acting autonomously to direct their attention according to their own interests and motivations. So the attention economy would actually realize many of the virtues of a laissez-faire model; in fact, I will argue that the dynamics of attention flows are a better model of “pure competition” than capitalist markets. My next post in the series will carefully distinguish between decentralization and self-organization. Part of the problem with laissez-faire economics in Enlightenment frameworks is that they conflate the two. Although money economies are usually decentralized (and capitalists tend to argue against centralization in the form of state regulations), they are usually not self-organized, and capitalists tend to resist self-organization in the form of labor movements and the like, preferring instead to maintain top-down control of the markets and resources. This has nothing to do wih human greed or goodness, this is the way the infrastructure works: money tends to accumulate in a few to the detriment […]

RESHARED POST FROM JOHN VERDON

John Verdon originally shared this post: This is a great book and a perfect complement to ‘Reinventing Discovery’. Weinberger explores the concept of knowledge as it became defined in practice within the age of the limited resources of ‘paper’. How paper required intense processes and structures of filtering in order to fit what was known or posited into the limited space of paper texts. This gave us a powerful illusion that the world was ‘knowable’. Science published primarily results that were confirming hypotheses – and the vast experiments and efforts that resulted in ‘negative’ results had no room in the finite space. Despite the fact that a great deal of utility could be derived from being able to look at results that were less successful in confirming hypotheses. Weinberger explodes the epistemic fiction of the data-information-knowledge pyramid for what it is – a fiction arising from the economic framework that would have knowledge endorse a control hierarchy. What the Internet now enables is the disclosing of everything – positive and negative. This reveals the tremendously ‘contested’ nature of all knowledge – reveals the larger unknowability of the world/universe. What science is – is not certain knowledge, but rather a paradox of both more robust theories and an even vaster horizon of unknowns. No matter how much we know – the horizon of the unknowns recedes faster to vaster spaces. I highly recommend this book – for anyone interested in knowledge and the digital environment.

RESHARED POST FROM JENNIFER OUELLETTE

eft a comment in the +Jennifer Ouellette‘s thread objecting to the thesis of this article, quoting my comment below: _______ I’m going to have to object pretty strongly to this article. The spirit is in the right place, but the lesson it draws is completely mistaken. There is no tyranny of the majority except as it expressed itself through the centralized authoritarian institutions that levy top-down control over the supposedly consenting masses. The article jumps from the clear fact that the majority is sometimes wrong to the mistaken conclusion that we have something to fear from the majority, or that the prevailing opinion is suspicious. This is an incredibly dangerous leap in logic, and should be examined a bit more carefully. Just for instance, the prevailing opinions of scientists is usually a pretty reliable guide to the truth. It doesn’t give you certainty, but the stronger the majority consensus, the more reliable we can take the conclusions to be. In fact, we take majority consensus to be one of the most impotant thresholds for the acceptance of a scientific theory there is. A mistaken scientific paradigm might be frustratingly difficult to overturn, but this stability is part of what makes scientific consensus such a strongly reliable indicator of the truth. In other words, there is no tyranny of the majority in science; in fact, it is an case where we all expect the majority to rule, even when we grant that the majority can be mistaken. A mistaken majority is only a problem when they wield the kind of power that we usually only grant to institutional bureaucracies like a state. Democratic states are designed to slow down the zeal of the majority to ensure justice and respect of equal rights. For instance, I don’t think so, but you might […]
