    <content type="xhtml"><div xmlns="http://www.w3.org/1999/xhtml"><p>I happened tonight to browse the cable TV listing and find on Bravo the <em>"Musical Brain"</em> documentary created by Christina Pochmursky for CTV and featuring Sting, Feist, Wyclef Jean and Daniel Levitin. <a onclick="window.open(this.href); return false;" href="http://en.wikipedia.org/wiki/Daniel_Levitin">Levitin</a> is a McGill professor of neuroscience that <em>became</em> a neuroscientist so that he can understand why we do music at all. The documentary is absolutely fascinating, even if a bit light. Levitin also worked recently on a new development, with <a onclick="window.open(this.href); return false;" href="http://www.bobbymcferrin.com">Bobby McFerrin</a>, called <em>"The Music Instinct"</em> -- that I crave to find and see. He wrote two very well known books on the same topics, "This is your brain on music" being a bestseller. Looking for more information on these, I found <a onclick="window.open(this.href); return false;" href="http://www.worldsciencefestival.com/video/notes-neurons-full"><em>"Notes and Neurons"</em></a>, a rather long panel at the the World Science Festival last year.

    <title>Freeloaders</title>
    <content type="xhtml"><div xmlns="http://www.w3.org/1999/xhtml"><p>We are a civilisation of freeloaders. OK, this is a recurrent theme with me (and even semipermanent), but once in a while I get peeved over the board of my patience. What tickled me this time is a video of a presentation Microsoft did a few days ago at <a href="http://ted.com">TED</a>, about its new <a onclick="window.open(this.href); return false;" href="http://techflash.com/seattle/2010/02/video_bing_maps_at_ted.html">bing maps</a> technology. I don't have anything against the technology or the obvious bloody competition with Google. But just look at the last 5 seconds of the video, to see the audience become lustful and almost perceivedly greedy. We absolutely love our hypertech toys. We despise the creators, we even physically molest them sometimes (think of the invetor of the blue LED), we bask in emotional and superstitious behavior, all the more enhanced by all the tech. But we forget to honestly realize that we are mostly freeloaders. That such near-magic requires efforts, and brains, and high quality education. We completely overlook the potential for even more wonderful (and actually useful) magic that could be created with the help of a thoughtful revival of social collaboration. We still allow wonderful brains to be lost through our awful economic predatory behavior. And all is a-OK as long as we get our freeloading toys.</p></div></content>
