With the video series "Applied Mathematics - Explaining Mathematics in an Understandable Way", the nine Styrian universities offer online lectures that show how close mathematics is to everyday life and applications. There is much more to mathematics than formulas, equations and numbers. Mathematics can be found everywhere in our everyday lives. The video series of the Styrian universities shows what mathematics can do, for example how it is behind the sound of an electric guitar and the delivery of letters, or how it makes drones fly. All lectures in the lecture series are given by experts from the nine Styrian universities. They are presented in a comprehensible way and are aimed at high school students, prospective students and, of course, anyone else who is interested.
