Function Carnival is the coolest site I’ve ever seen to develop graphing intuition among students. If you are a math teacher, doing the walk through at the top of the page is a must. It is so clever. This is the second thing Desmos has released in the last 6 months that has blown my mind. Check out this other post on modeling.
I wish I could get this poster for my new office. Found on iMathmaticus.
I caught a NY Times editorial on Jump Math and got curious. There are a lot of curriculums that claim to significantly improve student math performance. What intrigued me most about Jump Math is that it claims to push the extremities in a given class together. I hadn’t heard this before. That sounds fantastic. Imagine if you got everyone in your class working at a B+ to A level? That got my attention. Has anyone worked with this curriculum?
Did you ever want to know why X is the symbol of choice in algebra for representing an unknown quantity? Here is the quick crazy history.
I ran across a post on Futility Closet of a large scale art project in Finland. An artist built a small artificial mountain and planted 11,000 trees spiraling around it in golden ratio beauty. I will definitely pay a visit if I ever get to Finland. I started thinking what other sites would qualify as math tourism sites. My brainstorm was a short one.
The Bridges of Konigsberg. (Sadly there are no longer seven.)
The Brougham Bridge. (Where Hamilton first carved his quaternions.)
The Museum of Math in NYC
There has to be more, but I’m blocked. Help!
Infinity has always been controversial for mathematicians. Scientific American has a great article on the continuing debate. These questions and dilemmas have a special place in my heart. It was the first part of mathematics I’d seen that was as interesting as philosophy, my first love. It is a good read. I hope you enjoy.
On BrainPickings I came across a review of an absolutely stunning version of Euclid’s Elements. Produced in 1847 by mathematician Oliver Byrne, the book is obsessively visual like the proof below of the Pythagorean Theorem. I would love to find a poster for my office. Sadly Google came up empty. I did happen to find another 2010 review in the NY Times. You can also buy the book on Amazon. Maybe a holiday present for that geek in your life?
Stick this in your feed reader and love it. I just found an awesome Tumblr called Visualizing Math that collects all manner of math visualizations from all over the web. I especially the gifs like the above example (might need to click on it to see).
