Gallery: How networks help us understand the world As designer Manuel Lima points out in his TED Talk, A visual history of human knowledge, the network has become a powerful way to visualize much of what is going on in the world around us. “Networks really embody notions of decentralization, of interconnectedness, of interdependence,” says Lima. “This way of thinking is critical for us to solve many of the complex problems we are facing nowadays, from decoding the human brain to understanding the vast universe out there.” Here, Lima shares a few of his favorite network graphics. The Strengths of Nations This image shows the connections between scientific disciplines such as astrophysics, math and biochemistry.

Minds and Models: Types of encoding - Baddeley (1966) Semantic processing in LTM; acoustic in STM One of the most basic distinctions between long-term and short-term memory is that they process information in different ways. What is the evidence? One of the best studies was done by Baddeley (1966), who went on to create the working memory model a few years later. Participants were given lists of words with similar sounds (e.g. cat, mat...), similar meaning (large, big...) or lists of dissimilar words. Over the short term, there were many errors with similar sounding (acoustically similar) words, but in the long-term, mistakes were made for material with a similar meaning (semantically similar).
The dark side of data Now playing Recent events have highlighted, underlined and bolded the fact that the United States is performing blanket surveillance on any foreigner whose data passes through an American entity — whether they are suspected of wrongdoing or not.

An important rant, wrapped with a plea: to find alternative solutions to using American companies for the world's information needs. Minds and Models: Jacobs (1887) An early study of STM capacity Even people who haven't studied Psychology can probably tell you about the 'magical number' 7 (plus or minus two) - the supposed maximum number of items we can hold in our short-term memories. The best known study is Miller (1956), who tried to investigate the reason for the limit, finding that it was not limited to information load - the rationale being that a short word contains a lot more information than a binary digit (0 or 1) but yet the limit is still in the range of 5-9 items.

Human Memory Capacity is TEN TIMES MORE Than Previously Thought The picture above shows a synapse between an axon (green) and dendrite (yellow). A human brain could hold as much information as the entire internet, a new study finds. Human memory capacity is in the petabyte range, researchers at the Salk Institute have now found. How to watch a presidential debate (or win it): Tips from Amy Cuddy Amy Cuddy’s TED Talk, Your body language shapes who you are, has millions of views for a reason — everyone who watched it understood a little bit more about themselves.
