Forest of Math

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

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

moibus
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

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.

Math + Art

Here is an artist I feel certain will move your mathematical little heart. Check out Bianca Chang’s stunning gallery site. I came by it thanks to Chad Wys on Tumblr.

Math + Jokes

sad parallel lines

I get sent math jokes all the time. Just check my FB wall. I feel like I’ve seen them all. This was new to me though. Kinda sweet and funny? Thanks, Sue, for sending it my way.

Is Math Real?

I remember taking a Philosophy of Math class as an undergrad, and it was the first time I ran into the question, is math real? Or maybe a more nuanced way of putting it is, what kind of reality does it have? This video surveys the most popular theories. Warning, in case you have a lot to do today, you can wonder about this one a long time.

PBS Math Channel

There is a new PBS math channel on YouTube I learned about from Free Tech for Teachers. The content level is pretty basic, but it could be a nice review for students. I know a number of my algebra students still struggle with integer operations. I especially like the quiz video above. Very clever use of a YouTube video. The production quality, being PBS, is also a bit higher than a lot of the math videos around.
