Is This the Most Anti-Science, Anti-Environmental TV Ad Ever? | Peter H. Gleick - 1 views

  •  
    "Nature sucks. Cheap plastic toys are great. Science education sucks. Commercialism is great. Field trips to see nature are boring. Running wild around a chain store is fantastic."

Computer Science for Fun - cs4fn: What is Computational Thinking? - 2 views

  •  
    So what is Computational Thinking? Well it is a collection of diverse skills to do with problem solving that result from studying the nature of computation. It includes some obviously important skills that most subjects help develop, like creativity, ability to explain and team work. It also consists of some very specific problem solving skills such as the ability to think logically, algorithmically and recursively. Computer Science is unique in the way it brings all these diverse skills together.

What is data science? - O'Reilly Radar - 1 views

  • how to use data effectively -- not just their own data, but all the data that's available and relevant
  • Increased storage capacity demands increased sophistication in the analysis and use of that data
  • Once you've parsed the data, you can start thinking about the quality of your data
  • ...20 more annotations...
  • It's usually impossible to get "better" data, and you have no alternative but to work with the data at hand
  • The most meaningful definition I've heard: "big data" is when the size of the data itself becomes part of the problem
  • Precision has an allure, but in most data-driven applications outside of finance, that allure is deceptive. Most data analysis is comparative:
  • Storing data is only part of building a data platform, though. Data is only useful if you can do something with it, and enormous datasets present computational problems
  • Hadoop has been instrumental in enabling "agile" data analysis. In software development, "agile practices" are associated with faster product cycles, closer interaction between developers and consumers, and testing
  • Faster computations make it easier to test different assumptions, different datasets, and different algorithms
  • It's easer to consult with clients to figure out whether you're asking the right questions, and it's possible to pursue intriguing possibilities that you'd otherwise have to drop for lack of time.
  • Machine learning is another essential tool for the data scientist.
  • According to Mike Driscoll (@dataspora), statistics is the "grammar of data science." It is crucial to "making data speak coherently."
  • Data science isn't just about the existence of data, or making guesses about what that data might mean; it's about testing hypotheses and making sure that the conclusions you're drawing from the data are valid.
  • The problem with most data analysis algorithms is that they generate a set of numbers. To understand what the numbers mean, the stories they are really telling, you need to generate a graph
  • Visualization is crucial to each stage of the data scientist
  • Visualization is also frequently the first step in analysis
  • Casey Reas' and Ben Fry's Processing is the state of the art, particularly if you need to create animations that show how things change over time
  • Making data tell its story isn't just a matter of presenting results; it involves making connections, then going back to other data sources to verify them.
  • Physicists have a strong mathematical background, computing skills, and come from a discipline in which survival depends on getting the most from the data. They have to think about the big picture, the big problem. When you've just spent a lot of grant money generating data, you can't just throw the data out if it isn't as clean as you'd like. You have to make it tell its story. You need some creativity for when the story the data is telling isn't what you think it's telling.
  • It was an agile, flexible process that built toward its goal incrementally, rather than tackling a huge mountain of data all at once.
  • we're entering the era of products that are built on data.
  • We don't yet know what those products are, but we do know that the winners will be the people, and the companies, that find those products.
  • They can think outside the box to come up with new ways to view the problem, or to work with very broadly defined problems: "here's a lot of data, what can you make from it?"

Facebook can serve as personality test › News in Science (ABC Science) - 1 views

  •  
    "Companies who want to know more about prospective employees can learn a lot by checking their Facebook profiles, according to a new study. Jennifer Golbeck and colleagues at the University of Maryland surveyed the public profiles of nearly 300 Facebook users for information about their favourite activities, TV shows, movies, music, books, quotes, and membership in political or other organisations. They also looked at the "About Me" and "blurb" sections. The work did not include status updates or other data that is only available to users' online friends."

    "Ask a question, make a hypothesis, and observe what happens in this Sesame Street interactive science experiment! Help renowned scientists, Cookie Monster and Emma, investigate what sinks in water and what floats in water! Experiment with a rubber band ball, a lime and lemon, Ernie's rubber duckie, and a coconut. Start the experiment here! Will Bert's underpants sink or float? Go to http://www.sesamestreet.org/sinkorfloat for the full interactive experiment and find out."

YouTube - Khan Academy and the Effectiveness of Science Videos - 1 views

  •  
    "It is a common view that "if only someone could break this down and explain it clearly enough, more students would understand." Khan Academy is a great example of this approach with its clear, concise videos on science. However it is debatable whether they really work. Research has shown that these types of videos may be positively received by students. They feel like they are learning and become more confident in their answers, but tests reveal they haven't learned anything. The apparent reason for the discrepancy is misconceptions. Students have existing ideas about scientific phenomena before viewing a video. If the video presents scientific concepts in a clear, well illustrated way, students believe they are learning but they do not engage with the media on a deep enough level to realize that what was is presented differs from their prior knowledge. There is hope, however. Presenting students' common misconceptions in a video alongside the scientific concepts has been shown to increase learning by increasing the amount of mental effort students expend while watching it."

Brit Lab - YouTube - 1 views

  •  
    A growing number of videos that may be of interest for science. "for instance BBC Brit's Biggest Bangs is a fun, interactive video experience that allows users to channel their inner mad scientists, mixing dangerous chemicals with sometimes explosive results without a proper laboratory. The secret behind the interactivity is a central choose-your-own-adventure video around which annotations lead to separate videos that respond to your chemical selections." You choose your first chemical and then select another from among eight on the laboratory table.  You'll see the team scientist take each chemical from the table.  Then pause to consider-will it explode or won't it? If it doesn't, the oh so serious, oh so British narrator offers background on why the bang, or the lack of bang (NR or no reaction) may have disappointed, as well as what the resulting compound is and does.
