IntMath's Daily Math Tweet<\/em> was recognized this week in a list of Twenty Top Tweeters for Math (by Creative Education - no longer available).<\/p>\n

Here are some of the recent Daily Math Tweets that people have found interesting: <\/p>\n

    \n
  1. Using math to translate documents online<\/a> (Google, Babelfish) (This is an interesting application of statistics to language, in a Washington Post article) <\/li>\n
  2. Average person spends 15 minutes a day on YouTube<\/a><\/li>\n
  3. Convenient summary of conics<\/a>: line, circle, parabola, ellipse, hyperbola<\/li>\n<\/ol>\n

    \"Curriki\"<\/a><\/td>\nCurriki<\/a> is a place where students, parents and teachers can share learning resources.<\/p>\n

    You can easily search the site for math resources. Why not add some yourself? <\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

    This is an important trend in education - sharing resources via wikis and social media. <\/p>\n

    3. More funny GraphJam graphs<\/h2>\n

    Suitable for: <\/strong>Everyone.<\/p>\n\n\n\n
    \"More<\/a><\/td>\n\n

    Here are some more funny graphs courtesy of GraphJam. This is Part 2, following the ones I shared in a previous IntMath Newsletter. <\/p>\n

    4. Friday math movie: pentatonic scale<\/h2>\n

    Suitable for: <\/strong>Everyone.<\/p>\n\n\n\n
    \"dissonant<\/a><\/td>\nThe pentatonic scale is popular across all cultures. Some math is involved here!<\/p>\n

    5. MathJax - render math on the Web on all browsers<\/h2>\n

    Suitable for: <\/strong>Mostly for teachers who want to communicate with their math students in forums, blogs or in emails. <\/p>\n\n\n\n
    \"IE<\/a><\/td>\n\n

    I keep trying to find a good method for communicating math on a Web page. Here's one attempt - MathJax. This article contains a comparison of different solutions: jsMath, PHPMathPub, MathJax and MathTeX.<\/p>\n

    6. Final thought \u2013 things that count <\/h2>\n

    Einstein shares a good life lesson: <\/p>\n

    \n

    Many of the things you can count don't count. Many of the things you can't count, really count. [Albert Einstein]<\/p>\n<\/blockquote>\n

    Until next time, enjoy whatever you learn. <\/p>\n
