I woke up this morning to find that the robot video I shared last night has been +1’d or shared over 100 times in total, easily the most successful post that has appeared in my stream. Totally awesome, and a great opportunity to watch Ripples at work. https://plus.google.com/ripple/details?url=http%3A%2F%2Fwww.youtube.com%2Fwatch%3Fv%3D6b4ZZQkcNEo&context=z13edndznrbkfxkcf23oynlafpmds3ac1 If you haven’t been obsessing over Ripples already, the data analysis it offers is amazing! It even offers a timeline so you can see exactly how these memes spread across the G+ network. Does anyone have a favorite Ripples graph for fast spreading content? The KONY 2012 videos are an obvious choice. There were two videos that went around, one on YouTube and one on Vimeo: https://plus.google.com/ripple/details?url=http%3A%2F%2Fwww.youtube.com%2Fwatch%3Fv%3DY4MnpzG5Sqc https://plus.google.com/ripple/details?url=http%3A%2F%2Fvimeo.com%2F37119711 Notice that in both cases, the videos seem to spread much more by people sharing the video uniquely, instead of just resharing the posts of others. Pretty impressive for a video that spread so quickly! Notice also that in order to get reshared, you don’t have to be the first to publish the content, or even close the first. You just need a strong network of followers: notice the Shepard Fairey circle for the Vimeo video is pretty late to the game, but still commands a fairly large circle. Any other interesting Ripple graphs?

Jonathan Langdale originally shared this post: Complexity & Chaos, order through fluctuation “…how is choice made? There’s always pure chance, especially in physical systems. And there may also be outside influences. In social systems, these may be human intentions as well. So, at a bifurcation point, a small random fluctuation in the state or structure of a system is magnified and made permanent.” http://en.wikipedia.org/wiki/Self-organization http://en.wikipedia.org/wiki/Ilya_Prigogine “Self-Organization is the process where a structure of pattern appears in a system without a central authority or external element imposing it through planning.” This might be something I listen to when I go to sleep, I’ll keep it my watch later list. >But the dude that made the playlist put it out of order, which kinda sucks. I’m probably going to be too lazy to make my own. < +Jon Lawhead ordered this into a playlist: http://www.youtube.com/playlist?list=PL0F3AAFB03A09E5D0 >http://www.youtube.com/playlist?list=PLD205992E2126AF83&feature=plcp (over 2hr long, out of order)< This part 9 is 7m long and pretty interesting. .

Boston Dynamics has another awesome robot video on YouTube! “Sand Flea is an 11-lb robot with one trick up its sleeve: Normally it drives like an RC car, but when it needs to it can jump 30 feet into the air. An onboard stabilization system keeps it oriented during flight to improve the view from the video uplink and to control landings. Current development of Sand Flea is funded by the The US Army’s Rapid Equipping Force. For more information visit www.BostonDynamics.com.” http://youtu.be/6b4ZZQkcNEo Their collection of bots gets more impressive by the day.

“So this was back when the only “computers” were people doing math by hand. It was also back when machines were single-function. “Reprogramming” required a screwdriver. To think the kinds of thoughts Turing was thinking, you had to be either a genius or a psychic.” Kimberly Hayworth originally shared this post: Radiolab Podcast Articles – The Turing Problem 100 years ago this year, the man who first conceived of the computer age was born. His name was Alan Turing. He was also a math genius, a hero of World War II and he is widely considered to be the fat…

“”Using this form of cell-to-cell communication, colonies of billions or trillions of bacteria can literally reach a consensus on actions that impact people,” Onuchic explained. “Bacteria that previously existed harmlessly on the skin, for instance, may exchange chemical signals and reach a consensus that their numbers are large enough to start an infection. Likewise, bacteria may decide to band together into communities called biofilms that make numerous chronic diseases difficult to treat — urinary tract infections, for instance, cystic fibrosis and endocarditis.”” The article also mentions “quorum-sensing peptides”. A quick check online reveals the following: http://www.lib.ku.ac.th/html2/dmdocuments/QUORUM%20SENSING%20IN%20BACTERIA.pdf “Quorum sensing is the regulation of gene expression in response to ?uctuations in cell-population density. Quorum sensing bacteria produce and release chemical signal molecules called autoinducers that increase in concentration as a function of cell density. The detection of a minimal threshold stimulatory concentration of an autoinducer leads to an alteration in gene expression.” It occurs to me that this is a good check on the use of the term “biologically-inspired models”. The appeal of the term seems to drop out, given that our biological models themselves are described in terms familiar from social structures at higher levels of organization. Note: I was involved in debates over quorum at every Occupy I participated in. I hate quorum. Matt Uebel originally shared this post: Bacteria use chat to play the ‘Prisoner’s Dilemma’ game in deciding their fate When faced with life-or-death situations, bacteria ? and maybe even human cells ? use an extremely sophisticated version of “game theory” to consider their options and decide upon the best course of action, scientists reported here today. In a presentation at the 243rd National Meeting & Exposition of the American Chemical Society (ACS) they said microbes “play” a version of the classic “Prisoner’s Dilemma” game.

#consensus #selforganization MILOS JANATA originally shared this post: Would you behave similar to the person in the video? Groupthink is a psychological phenomenon that occurs within groups of people. It is the mode of thinking that happens when the desire for harmony in a decision-making group overrides a realistic appraisal of alternatives. Group members try to minimize conflict and reach a consensus decision without critical evaluation of alternative ideas or viewpoints. http://en.wikipedia.org/wiki/Groupthink

“A preferential attachment process is an urn process in which additional balls are added continuously to the system and are distributed among the urns as an increasing function of the number of balls the urns already have. In the most commonly studied examples, the number of urns also increases continuously, although this is not a necessary condition for preferential attachment and examples have been studied with constant or even decreasing numbers of urns.” Welp, guess I found the model I was looking for. http://en.wikipedia.org/wiki/Preferential_attachment Preferential attachment – Wikipedia, the free encyclopedia A preferential attachment process is any of a class of processes in which some quantity, typically some form of wealth or credit, is distributed among a number of individuals or objects according to h…
