Math Links for Week Ending July 17, 2015

Here is a loaded question: Is Math Important? This is what these 5 panelists discussing over the course of an hour or so. They make their case for (and against?). I was hooked as soon as I heard Steven Strogatz started with takedowns (kind of) of the standard reasons to say "Yes". Take some time to watch and listen. Thanks to @profkeithdevlin for this

I love cool uses of data. Here is a dynamic visualization of sunset/sunrises created realtime from scraping Instagram for images tagged with #sunset or #sunrise and then mapping them onto the globe. Check out the link below to see the dynamic visualization.

I really like this very simple tweak to questioning that @k8nowak has on a recent post. She was having trouble with students not answering questions about other student's work. She got around it by changing the question she asked to "would you explain your understanding of Bianca's Solution?" I like it because it is a little more friendly than "Does anyone have any questions about Bianca's Solution?"

The Nardo Ring is a circular test track in Italy and here is a 3Act task on a problem about two cars driving around in it. Certainly any class dealing with circumference and rates could make use of this.

It's summer time so why not have a mathematical parody about factoring quadratics. Thanks to @k8nowak for this one

When ever I see a fountain I see a quadratic. This time, at the corner of Queen and University in Toronto, it was a great paraboloid.

It is always nice when @JohnAllenPaulos continues his books on innumeracy via twitter. This time on a menu and dealing with rates and area of a circle.
