The Deep Mind of Demis Hassabis - "The big thing is what we call transfer learning. You've mastered one domain of things, how do you abstract that into something that's almost like a library of knowledge that you can now usefully apply in a new domain? That's the key to general knowledge. At the moment, we are good at processing perceptual information and then picking an action based on that. But when it goes to the next level, the concept level, nobody has been able to do that." (previously: 1,2) [more inside]
Time after time, professors in mathematics and the sciences have told me that building well-ingrained chunks of expertise through practice and repetition was absolutely vital to their succes Understanding doesn’t build fluency; instead, fluency builds understanding. In fact, I believe that true understanding of a complex subject comes only from fluency.
Hyperreal numbers: infinities and infinitesimals - "In 1976, Jerome Keisler, a student of the famous logician Tarski, published this elementary textbook that teaches calculus using hyperreal numbers. Now it's free, with a Creative Commons copyright!" (pdf—25mb :) [more inside]
Whale.fm is a project (which you can contribute to!) to help "marine researchers understand what whales are saying." - really it's a project looking at the effects that manmade sound has on marine life, but what whales are communicating with their songs is still a really interesting question, so I've listed some relevant links in extended description.

Is Psychometric g a Myth? - "As an online discussion about IQ or general intelligence grows longer, the probability of someone linking to statistician Cosma Shalizi's essay g, a Statistical Myth approaches 1. Usually the link is accompanied by an assertion to the effect that Shalizi offers a definitive refutation of the concept of general mental ability, or psychometric g." [more inside]
The simulated brain - "First computer model to produce complex behaviour performs almost as well as humans at simple number tasks." [1,2,3,4,5,etc.]
Are you the type of person who, when flipping through a book or scanning a website, immediately searches for the diagrams or charts because you'd rather absorb the information visually than have to read a bunch of text? If so, then you are probably a visual learner and you may find Useful Charts helpful. The goal is to present useful information in the form of study charts so that students, teachers or simply those interested in increasing their general knowledge can absorb the information quickly and visually.
Citizen science refers to science conducted by average persons, e.g., people who are not full- or part-time professional scientists but nevertheless have a keen interest in scientific inquiry. Citizen Science Center is a resource for books, papers, discussions, and project listings related to citizen science that aims to convince you to get your hands dirty and do science now.
In June of 1973, spurred on by the recent discovery of a dying bird in his garden, 9-year-old Anthony Hollander wrote to the presenters of Blue Peter — the BBC's much-loved children's television show — and asked for assistance in his quest to "make people or animals alive."
Khan Academy and the Effectiveness of Science Videos is an 8 minute video by Derek Muller that offers some skepticism as to the usefulness of science videos that only teach the facts without investigating existing misconceptions. TL;DW? Here's a 1 minute 29 second version. Too brief? Here's his PhD thesis.
He was taught to use matches, a skill he picked up quickly. There’s something eerie about watching Kanzi strike a match. The way he then holds the flame — taking care not to burn himself — is remarkably human. (video)
In February 2011, every teacher in Providence, Rhode Island was pink slipped. Not all 1,926 of them got fired, of course, but with the district facing a $40 million deficit, anything is possible. The district says it needs flexibility, just in case. Every school district in the United States faces its own version of what’s happening in Providence. However, “IMAGINATION: Creating the Future of Education and Work” is focused not on how we got here but rather how we can move forward from here immediately even as the education system continues to struggle.

Vanessa Mae Nicholson is one of Britain’s most successful young musicians. A classical violinist and former child prodigy who self-describes her crossover style as "violin techno-acoustic fusion," her fans praise her modern creativity and frenetic, lightning-fast riffs. But is her talent learned or genetic? Documentary from BBC1 in 2008: Vanessa Mae - The Making of Me: 1, 2, 3, 4, 5, 6. [more inside]
Best of History Web Sites (from EdTechTeacher,) is a resource of annotated and rated-by-content links to over 1200 history web sites across a broad range of related topics. The site also offers links of special interest to educators: hundreds of K-12 lesson plans, teacher guides, activities, games and quizzes and more.
The Polar Discovery team has documented science in action from pole to pole during the historic 2007-2009 International Polar Year, and covered five scientific expeditions. The science projects explored a range of topics from climate change and glaciers, to Earth’s geology, biology, ocean chemistry, circulation, and technology at the icy ends of the earth. Through photo essays and other multimedia, they explain how scientists collected data and what they discovered about the rapidly changing polar regions. From the awesome folks at WHOI.
grumblebee's post about cell size and scale the other day was quite fascinating. Pulling back to the home for that site, the Genetic Science Learning Center at the University of Utah delivers educational materials on genetics, bio-science and health topics ranging from stem cells to gene therapy, and from epigenetics to heredity. Explore the neurobiology of normal and addicted brains and the genetic contribution to this chronic disease.

There are times when having a fully developed brain can almost seem like an impediment. Are babies more aware of the world around them than adults are? Can "thinking like a baby" lead us to be more in tune with our creativity and our ability to learn? Scientists have taken a new look inside the baby mind, which is "unfocused, random, and extremely good at what it does."
Microscope Imaging Station opens a door to the wonder of the microscopic world and allows the layman to explore it. They seek to recreate some of the excitement and wonder that the earliest biological researchers found. Features include cells with potential as well as bad oogy. The microscopic Galleries are inhabited by zygotes and organelles.
World of Science contains budding encyclopedias of astronomy, scientific biography, chemistry, and physics. This resource has been assembled over more than a decade by internet encyclopedist Eric Weisstein with assistance from the internet community. MeFi visited Weisstein's Mathworld a couple years ago.
Sal Khan likes explaining things, and he's really good at it. Here he is on CNN giving an excellent explanation of the financial crisis. And here's a great explanation of Newton's Law of Gravitation. His YouTube channel has over 700 lectures and you leave understanding everything he talks about no matter the subject.
Science Hack is a unique search engine for science videos focusing on Physics, Chemistry, and Space. For example, things to do with sulfur hexafluoride. Still growing, the editors are presently indexing other scientific fields of study including Geology, Psychology, Robotics and Computers. Ever wonder why things go bang?

Motion Mountain - "The project aims to produce a simple, vivid and up-to-date introduction to modern physics, with emphasis on the fundamental ideas of motion. 'Simple' means that concepts are stressed more than formalism; 'vivid' means that the reader is continuously challenged; 'up-to-date' means that modern research and ideas about unification are included."
The Human Speechome Project - "A baby is to be monitored by a network of microphones and video cameras for 14 hours a day, 365 days a year, in an effort to unravel the seemingly miraculous process by which children acquire language.". Selected video clips. Paper (PDF, 750KB). To test hypotheses of how children learn, Prof Deb Roy's team at MIT will develop machine learning systems that “step into the shoes” of his son by processing the sights and sounds of three years of life at home. Total storage required: 1.4 petabytes.
Howtoons: comics meet little science projects. From the site: Much like MIT has OpenCourseWare distributing curricular materials for college students worldwide, our Howtoons are OpenKidsWare, with practical build-it projects letting kids learn-by-doing, MIT-style!
