It's that time of year again. I need to post some links to other blogs of interest and some re-runs from my own. If you want to take a week or so off, you can always look through the archives at Sabinocanyon.net - Over 1400 posts to choose from!
Some cool stuff:
Another great TED talk from Hans Rosling (and his son Ola)
And a book I'm reading (albeit slowly): How not to be wrong: The power of mathematical thinking by Jordan Ellenberg. If you fear math, hate math, and/or don't remember much about math, this is the book for you. Ellenberg explains mathematical concepts to help you better understand (and not be fooled by) graphs, studies, media proclamations, and all manner of surveys. And there's no homework!!
