one of my favourite maths blogs, proof.
proof math is beautiful
This blog will contain a couple of interesting bits from the web everyday. The first one is this image from artist Tomas Saraceno, making me think of soap bubbles.
If you would like to say something about the website or the tasks please write it here.
i'm particularly interested if you have ways to improve or augment the tasks, or would like to contribute a task of your own.
