Clarke is dead on target in this video. Any sufficiently advanced technology is indistinguishable from magic, and Clarke is a wizard. Katka Filipová originally shared this post:

Krauss gets destroyed in this review. David Albert is a total boss. Even his glancing blows completely rip apart contemporary metaphysics and religious practice. If you are a fan of intellectual steam-rolls, read this. Jeremy Shipley originally shared this post: This is a good review. I’d be interested in second opinions on what Krauss is saying. ‘A Universe From Nothing,’ by Lawrence M. Krauss Lawrence M. Krauss argues that the laws of quantum mechanics answer our most profound questions.

We are going to crack this thing really soon. Hold on tight.

Apparently I spent all morning arguing with the GM of a $1+ billion international company about how capitalism is obsolete. Lol internet. I think I did a good enough job, when you take into account that I’m trying to be on my best behavior in G+. Either way, it is an interesting discussion that I’d like to save for future reference, so I’m linking it here.

This article attempts to flesh out that construct, by providing rich insights into how members of a group that spans various professional communities of practice collaborate in jointly constructing a socio-technical artifact—a knowledge management system—within its context of application.” Social Computing Group – Babble People and projects at IBM Research

Jeff Sayre originally shared this post: What Small Eyes You Have! An team of researchers are working on building an in vivo mirco-robot that would scour the human body, searching out diseases and monitoring the health of its host. From the article: Cyberplasm will be designed to mimic key functions of the sea lamprey, a creature found mainly in the Atlantic Ocean. It is believed this approach will enable the micro-robot to be extremely sensitive and responsive to the environment it is put into. Future uses could include the ability to swim unobtrusively through the human body to detect a whole range of diseases. #SyntheticBiology #robotics #Cyberplasm #cybernetics #SynapticWeb ‘Living’ micro-robot could detect diseases in humans A tiny prototype robot that functions like a living creature is being developed which one day could be safely used to pinpoint diseases within the human body.

The Standing Ovation Problem “The basic SOP can be stated as: A brilliant economics lecture ends and the audience begins to applaud. The applause builds and tentatively, a few audience members may or may not decide to stand. Does a standing ovation ensue or does the enthusiasm fizzle? Inspired by the seminal work of Schelling (1978), the SOP possesses sucient structure to generate nontrivial dynamics without imposing too many a priori modeling constraints. Like Schelling’s work, it focuses on the macro-behavior that emerges from micro-motives, and relies on models that emphasize agents driven by simple behavioral algorithms placed in interesting spatial contexts. Though ostensibly simple, the social dynamics responsible for a standing ovation are complex. As the performance ends, each audience member must decide whether or not to stand. Of course, if the decision to stand is simply a personal choice based on the individual’s own assessment of the worth of the performance, the problem becomes trivial. However, people do not stand solely based upon their own impressions of the performance. A seated audience member surrounded by people standing might be enticed to stand, even if he hated the performance. This behavioral mimicry could be strategic (the agents wants to send the right signal to the lecturer), informational (maybe the lecture was better than he thought), or conformal (he stands so as to not feel awkward). Regardless of the source of these peer effects, they set the stage (so to speak) for interesting dynamic behavior.” Miller, John, and Scott E.
