Made of Math

There are so many opportunities to appreciate mathematics when you travel. I recently spent three weeks in Europe.

When no one is walking in front of them, they look like the banner above.

But when you stand in front of the projector and wave your arms around, the little umbrellas go nuts. They fly away from your hands and slowly settle back to their self-similar umbrella shape.

Linear Algebra mainly.

I could watch people do this for hours. Well, in reality, I watch people do this for about five minutes until I feel super creepy and go sit at my gate and read a book!
