The past decade has witnessed a momentous transformation in the way people interact and exchange information with each other. Content is now co-produced, shared, classified and rated on the Web by millions of people, while attention has become the ephemeral and valuable resource that everyone seeks to acquire.
This talk will focus on how social attention is allocated among all media and how it decays as novelty fades and new content is created. This will be followed by a description of the role that attention plays in the production and consumption of content within social media, how its dynamics can be used to predict future trends, and its connection with the emergence of a public agenda.

TED Talks Imagine a set of electronics as easy to play with as Legos. TED Fellow Ayah Bdeir introduces littleBits, a set of simple, interchangeable blocks that make programming as simple and important a part of creativity as snapping blocks together.
Can your social network make you fat? Affect your mood? Political scientist James H. Fowler reveals the dynamics of social networks, the invisible webs that connect each of us to the other. With Nicholas A Christakis, Fowler recently coauthored, Connected: The Surprising Power of Our Social Networks and How They Shape Our Lives..
Brian Christian is the author of The Most Human Human: What Talking with Computers Teaches Us About What It Means to Be Alive. His writing has appeared in The Atlantic, Wired, The Wall Street Journal, Gizmodo, and The Guardian.
Each year Turing Test sponsors confer the title of "Most Human Computer" to the machine most successful at persuading the judges it’s human. But there is another prize, bizarre and intriguing, for the real person who does best; the "Most Human Human" award.
Using his experiences as a “confederate” in the 2009 Turing test, and drawing on science, philosophy, literature and the arts, Brian Christian discusses the profound ways in which computers are reshaping our ideas of what it means to be human.

Psychologist Jonathan Haidt asks a simple, but difficult question: why do we search for self-transcendence? Why do we attempt to lose ourselves? In a tour through the science of evolution by group selection, he proposes a provocative answer.
TED Talks We believe that we should work to be happy, but could that be backwards? In this fast-moving and entertaining talk from TEDxBloomington, psychologist Shawn Achor argues that actually happiness inspires productivity.
TED Talks Onstage at TED2012, Peter Diamandis makes a case for optimism -- that we'll invent, innovate and create ways to solve the challenges that loom over us. "I’m not saying we don’t have our set of problems; we surely do.
When does a social group reach agreement by imitation processes? I will discuss how we answer this question by considering the voter model, a paradigmatic example of simple model of social behavior. Aspects to be addressed include the role of tie heterogeneity and non persistent ties in social networks, as well as the heterogeneity in the timing of interactions and the coexistence of imitation and rational behavior. I will also discuss the competition between self-organization and external messages or mass media in models of social consensus.
"What would you attempt to do if you knew you could not fail?" asks Regina Dugan, then director of DARPA, the Defense Advanced Research Projects Agency. In this breathtaking talk she describes some of the extraordinary projects -- a robotic hummingbird, a prosthetic arm controlled by thought, and, well, the internet -- that her agency has created by not worrying that they might fail. (Followed by a Q&A with TED's Chris Anderson)

I will present a few perspectives on the current trends in education from the point of view of a complex systems scientist. Among the likely topics: centrally prescribed metrics and standardized testing, charter schools, and innovations in mathematics education. The discussion will be based upon analysis of complexity and scale, the substructure of neural cognition, and other relevant complex systems insights.
This talk was delivered on March 14, 2012 at the Kaput Center at the University of Massachusetts Dartmouth
Can government be run like the Internet, permissionless and open? Coder and activist Jennifer Pahlka believes it can -- and that apps, built quickly and cheaply, are a powerful new way to connect citizens to their governments -- and their neighbors.
Google Tech Talk (more info below) December 1, 2011 Presented by Raja (Puragra) GuhaThakurta. ABSTRACT The lecture "Our Place in the Cosmos" explains how we (and, for that matter, all complex life forms) are connected to the Universe around us. This connection relies on the fact that our Milky Way and other galaxies like it play host to cosmic recycling processes that involve the formation of stars and their planetary systems inside nebulae (dense gas/dust clouds), nuclear fusion reactions that occur within stars, and the death of massive stars in explosions known as supernovae. As a result of these processes the Earth contains elements like carbon, nitrogen, and oxygen, all of which are essential ingredients of protein molecules that are basic building blocks of life on Earth. To understand our origin we must therefore understand how galaxies form as part of the so-called cosmic web and evolve via galaxy cannibalism: merging and destruction of small satellite galaxies whereby their stars are incorporated into larger galaxies. This portion of the story will take us back to the earliest imaginable times in the history of the Universe. The talk will be illustrated with the latest astronomical images obtained using space-/ground-based telescopes and state-of-the-art computer simulations.
TED Talks In his lab at Penn, Vijay Kumar and his team build flying quadrotors, small, agile robots that swarm, sense each other, and form ad hoc teams -- for construction, surveying disasters and far more.
