Math Links for Week Ending Mar 8, 2013

I am usually not an advocate of politically charged statistics without references but it is my understanding that this data isn't too far from the truth. The thing that makes this really nice though is that it is a really good example of data visualization and perception

A few weeks ago TI announced the new iPad app for nSpire. At the time it wasn't available in Canada. That has changed. Now you can get it here in Canada and if you act now (by March 10th) you can get it for the special discounted rate of $4.99 (regular price is $29.99). So don't delay. Watch a video demo here.

This is a great site for real time Earthquake data. Put in your parameters and then it spits out a table with all the relevant data about earthquakes in your search parameters. You can then copy and paste the data into Excel or Fathom with only minimal massaging. Here is my Fathom file of the 2011-2012 earthquakes.

Another fun source of data is Wolfram Alpha. For example you can, for example, get data about the popularity of your name. For example, here is the data on my first name, David.

Also from Wolfram Alpha is some pictures drawn with functions. I like the Rolling Stones the best as it contains the symbol for Pi (look closely)

Here is a nice picture of a kids project that is a great representation of the amount of sugar in drinks. Its not perfect (eg the bags used are different sizes) but that could be a point of discussion.
