Title: "Simple things that we don't know."

Abstract: People have been doing mathematics for thousands of years! There are now some things that we understand pretty well. We can compute trajectories of rockets pretty accurately and we are also decent when it comes to adding numbers. But there's also many, many things, some of them very easy and simple to explain, that we know very little about. This is great because it gives mathematics the chance to grow, it shows what we need to understand better. We will discuss some of these very simple things that we know nothing about.
