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.

## Math + Emotional States

I wish I could get this poster for my new office. Found on iMathmaticus.

## Jump Math

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?

## Where did X come from?

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.

## Forest of Math

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!

## Still Fighting After All These Years

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.

## A Rubik’s Cube the Size of a Building

Puzzle Facade from Javier Lloret on Vimeo.

This isn’t properly math related, but I can’t help it. This device for turning building facades into Rubik’s cubes is too geektastic not to post. I promise a post on set theory next week to make up for it

## Euclid and Graphic Design

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?

## Visualizing Math

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).

## Love and Math

I caught a really promising book review for Love and Math by Edward Frenkel in the New York Times. I’m already 10 books behind on my reading list right now, but I think it’s about to be 11.
