Math Links for Week Ending June 14th, 2013

Hans Rosling does it so suscinctly. The way he shows data makes it so easy to see why understanding it is so important.

I love this "heat" map. Which birth dates are the most popular. There is a wealth of data here. Not just in the fact that the actual data table is available but in the extra post about how people missinterpret this type of graph. And for that matter I like this blog.

Apparently there is no reason to teach anything about polynomials and functions. Thanks Wolfram Alpha now I'm out of a job!

"They may even resist you. They signed their "didactic contract" years and years ago.They signed it. Their math teachers signed it. The agreement says that the teacher comes into class, tells them what they're going to learn, and shows them three examples of it. In return, the students take what their teacher showed them and reproduce it twenty times before leaving class. Then they go home with an assignment to reproduce it twenty more times.
Then here you come, Ms. I-Just-Got-Back-From-A-Workshop, and you want to change the agreement? Yeah, you'll hear from their attorney."

It is kind of technical (and a bit long) but I think it really hits the idea of what randomness is. And I love that he actually actually generates random numbers by actually using a radioactive sample of
