Math LInks for Week Ending Aug. 30, 2013

Data from Twitter has given empirical data to measure the subtle differences between a nerd and a
geek. 2.6 million tweets from Dec 2012 were analyzed to find terms associated with geek and nerd and a cool graph was born.

Everyone that teaches quadratics will eventually use a "frame" problem. Here is a nice rework of an already good activity dealing with this type of problem from the I Speak Math blog

One of the things that Dan Meyer did this summer is called "Makeover Monday"
where he and his readers take various bits of textbook work and retool them. Here are the results:
Bedroom Area (Area, Rates)
Checkerboard Boarder (Quadratics, Patterning)
Bedroom Carpet (Composite Area, Rates)
Internet Plans (Systems of Equations)
Meatballs (Composite Volume)
Tire Marks (Root Functions)
Postage Rates (Piecewise Graphs)
Ferris Wheel (Periodic Functions)
Shipping Routes (Systems of Equations, Patterning)
Boat Race (Vectors, Geometry)
Penny Circle (Quadratics)

One dot, one person. That is, over 300 million dots representing each person in the US. All plotted out and colour coded by race. Neat visualization. Here is the link to the large zoomable map.

I must be fascinated by these things because I know I have pointed them out before. These pictures made of curves are neat. But unrelated to this is a new feature of Wolfram Alpha to "Analyze My Facebook Data". To do this you have to give Wolfram Access to your Facebook page but then it does its magic. Give it a try.

I really like Steven Strogatz. The way that he tries to make math attainable to the average person. He really sees the beauty in math and simplifies it. Listen here for an interview where he talks about his book The Joy of X.

Feynman Point Poems are poems that are based on a particular place in the expansion of Pi. There is a place where there is 6 nines in a row. So these poems all have six words that each have 9 letters. Read about them here:

Interesting findings about why girls don't get into STEM (Science, Tech, Engineering and Math). It turns out its because there aren't enough good female role models in those fields. Its kind of cyclical. Listen here

When ever there is an airline crash people feel that it is unsafe to fly but in reality flying has become safer and safer. I like it also because it is data per million miles flown so it is relative to flying time. Take a look at the data.
