World of Mathematics
"Everybody should understand concepts like prime numbers, graph theory or differential equations. They are of fundamental importance in technology and for understanding of the universe we live in, and they are incredible exciting and beautiful. Mathematics is an essential part of our culture, just like Mozart and Shakespeare."[1]<p>This is the key point, I think. Most of my non-technical friends have only vague ideas or know nothing about these topics. Actually working with differential equations might be hard, but most people should at least have an understanding of their use cases and why they are important or beautiful. And this way of presenting math is of course much more compelling than any high school math book I ever saw.<p>[1] <a href="http://mathigon.org/about" rel="nofollow">http://mathigon.org/about</a>
