 Mathematics is a language at the heart of our universe. It is to science what creative writing or poetry is to language. It allows for intricate things to be succinctly and beautifully expressed. You think that maths is one subject, but there are so many parts to it. Mathematics is a creative subject. The gate mathematicians are creating new ideas, new things. That's part of the joy of mathematics. It's kind of edifying to know that the sort of maths we're playing with here is the same maths that Plato was playing with almost 2,000 years ago. Maths is a language that we need to understand. It is used across many disciplines with many applications. Einstein himself had to create a theory of mathematics to capture his general relativity. If you want to express something that is complex, you need a language by which you can do it. I get asked all the time whether mathematics is invented or discovered. Are we like just inventing a language that helps us explain complexity? There are many things we know how to do without being even aware that there's a rule for it. The way of building language is based on the same operation. Mathematics is quite literally everywhere. We're here at the University of Grinch campus designed by Sir Christopher Wren, who had mathematics at the heart of his architectural designs. It's even in the music that we listen to. There are so much mathematics to be had in music, not just because of its rhythms, because of its structure of composition, but also in its fundamental frequencies. It so happens that sounds that we find really, really pleasing to the ear have a mathematical structure. You can say that music is a way that mathematics sounds. The thing I love about mathematics is it's a universal language of the sciences. Mathematics is the thing that allows you to break apart something very complex and just see what the most important features of something are. I find this really wonderful because even though people doing coding, they may not regard themselves as mathematicians, but they are doing that in a really important sense. The context of how this could be used in real life wasn't something which I kind of picked up on. It's only through using this code allows me to be able to then create a kind of procedural geometry and now also teach this. One really important feature about maths is you don't have to be a genius in mathematics to do mathematics and enjoy the process of doing mathematics. Naira Chamberlain said you don't need anyone's permission to be a mathematician. Absolutely. If you enjoy mathematics at school, you're a mathematician. There's almost as many careers to have in mathematics as there are people to do careers. Graduates here at Greenwich go off to do a very wide variety of different roles. They go into data, they go into operational research, statistics, all sorts of things. Math is absolutely everywhere. Mathematics is only going to play an increasingly important role in our society. No matter what discipline it is, it always comes back to mathematics.
