I'm sitting here on Thursday night heading in to the long weekend with my cousin, who came up from NYC. I'm the geek in the family (surprising, I know). At any rate, we're sitting here talking about nerdy things and she proclaims that she wants to know what the internet is. Does someone own it? How does it work? So, I immediately jumped on TED.com , my favorite spot of all things brainy. And then I found this video of Andrew Blum explaining it. It left my dear, beloved cousin with her mind blown and tons more questions, but I thought it was an excellent explanation. With our lives so dependent on the internet, and our classrooms becoming more so, understanding how it works can be empowering. So, check it out for your long weekend brain boost.
