**There was mathematical mayhem in DC on Saturday!**

Did you miss it? Let me try to capture the day with some photos:

That’s just ONE room, just one part of a very large and increasingly popular *National Math Festival*.

This was the second festival which is held every two years (alternating with the the US Science and Engineering Festival). The festival was a huge success and was very well attended. I was a little cautious about attendance predictions, given that the festival moved to the convention center from the DC Mall–a location which benefited from wandering foot-traffic.

This year, however, we benefited from the *rain*. It was dark and rainy all day long, but the National Math Festival provided a wonderful rainy-day escape from the dreary weather. See? Look at all the fun we’re having!

The photos you’re seeing here are all from the travelling exhibits brought to us by the *Museum of Mathematics *in NYC. I helped MoMATH coordinate volunteers this year, just as I did two years ago. And our volunteers were AWESOME!

We engaged thousands of people throughout the course of the day in meaningful mathematical play. There is a great need for this kind of popular-focus on mathematics, illuminating the beauty, joy, and *fun* of mathematics, rather than the impression people have of difficulty and drudgery.

All my photos are MoMATH-focused, since that’s where I spent my day. You can find even more of my photos here. And you can see more coverage in my twitter feed. For example, here’s a little clip of some juggling-math:
