Audio The sounds of made by a West Indian furrow lobster – via Boing Boing Radio Berkman – Facts Are Boring – via itself This week we tear apart the difference between Truth, Fact, and Evidence, and the quiet, but irreplaceable, role of the humble factchecker in our media: Author/factchecker Jim Fingal on the Lifespan of a Fact Former GQ intern and factchecker Gillian Brassil Veteran Atlantic Monthly factchecking department head Yvonne Rolzhausen David Weinberger, author of the recent book Too Big To Know From the New Blogs Why was melamine so toxic? “Because it’s not, really. It’s not supposed to be absorbable by the human body,” Jia says. Its LD-50 (“lethal dose-50?), or the dose at which 50 percent of those exposed would die, is 3161 mg/kg in rats, an incredibly low toxicity. So why had so many children gotten sick?

I don’t know what it is about posters lately but this is simply awesome. It’s from the movie Mega Shark vs Giant Octopus1. Pitching this WCYDWT style would be awesome. Any crazy physics teachers out there willing to give this a shot? I was utterly bored by physics both times2 I took it but I’d have spent a happy week trying to figure stuff like this out. Found via the always awesome Super Punch 1 It’s now on my list to watch. I don’t know why Jim Groom hasn’t dedicated an entire blog to this yet. 2 I took it once in HS and once in college. I didn’t fail people. I only failed classes when I had personality conflicts with teachers.
The Santa Monica ad agency RPA cut half-inch grooves into a quarter-mile stretch of Avenue K, in the exurban L.A. desert city of Lancaster. The grooves were synched in such a way that driving over them at precisely 55mph caused Rossini’s “William Tell Overture” — a.k.a. the Lone Ranger theme — to echo in the air around you. –VSL So how cool would this be for physics, science and math? Lots of concepts to explore in a simple entertaining little Youtube clip. Wonder what it’d take to make your own version? Not necessarily with a real car- maybe a remote controlled model?
David Harrison at The University of Toronto’s School of Physics has a wonderful collection of physics animations. Many of them are interactive, and some allow the viewer to make predictions before the animation plays. Now, I have to be honest. I made it through physics because the top three students in my graduating class (wonderfully kind ladies) befriended me my senior year of high school. I remember little about the class except my teacher insisting that “1 and 1 makes three.” Needless to say, physics is not my strong suit, but I enjoyed playing with these animations. I found myself testing what would happen with this change or that one. Let me know if you can use these in your classroom. I’m trying to dig up more science and math resources, but these subjects are not my ex-per-tise. Link
