We may not always realize it, but mathematics permeates nearly every aspect of our life. Whenever we access a network, be it the internet, the electricity grid or the network of railway lines, mathematical models are used to keep them running. Our monetary system relies on mathematical models, and the encryption algorithms we trust every day when we use an ATM or transfer money online would not be possible without mathematics. All exact sciences have a mathematical foundation, and mathematics becomes more and more important also in disciplines such as medicine and the social sciences.
But mathematics is not just a tool for applications. Mathematics is also a framework for deep thought, intellectual challenges and creativity.
