Complex analysis – the perfect subject for combining visual and analytic thinking. I just read “Visual Complex Analysis” by Tristan Needham, a basic book on complex analysis: lots of historical references, uncompromising explanations, lots of problem solving and plenty of beautiful illustrations!

I have this book. It is very good.

I’m substituting for a 9th- and 10th-grade math teacher, and she has a number of neat posters on her wall, ranging from the application of mathematics to robotics, to its role in black hole physics, to its cultural impact on the NBA.

Here’s the description of the poster set, which comes from the AMS:

The Mathematical Moments program promotes appreciation and understanding of the role mathematics plays in science, nature, technology, and human culture.

The AMS has many, many more online, many of which are accompanied by podcasts, shorter versions, and translations into a variety of languages. Pictured are:

Check them out and enjoy!

:

given any loop (of any shape), are there four points that, when connected, form a square? (unsolved) or a rectangle? (solved and proved in this video)

topology is really cool!! and so is this video, it’s got really nice explanations and does so in a way that people with no topology knowledge can understand
PS topology was used by this year’s winners of the nobel prize in physics!!
