In 17 chapters this book attempts to deal with well-known and less well-known topics in
mathematics. This is done in a vivid way and therefore the book contains a wealth of colour
illustrations. It deals with stars and polygons rectangles and circles straight and curved
lines natural numbers square numbers and much more. If you look at the illustrations you
will discover plenty of exciting and beautiful things in mathematics. The book offers a variety
of suggestions to think about what is depicted and to experiment in order to make and check
your own assumptions. For many topics no (or only few) prerequisites from school lessons are
needed. It is an important concern of the book that young people find their way to mathematics
and that readers whose school days are some time ago discover new things. The numerous
references to internet sites and further literature help in this respect. Solutions to the
suggestions interspersed in the individual sections can be downloaded from the Springer
website. The book was thus written for everyone who enjoys mathematics or who would like to
understand why the book bears this title. It is also aimed at teachers who want to give their
students additional or new motivation to learn. This book is a translation of the original
German 2nd edition Mathematik ist schön by Heinz Klaus Strick published by Springer-Verlag
GmbH DE part of Springer Nature in 2019. The translation was done with the help of artificial
intelligence (machine translation by the service DeepL.com). In the subsequent editing the
author with the friendly support of John O'Connor St Andrews University Scotland tried to
make it closer to a conventional translation. Still the book may read stylistically
differently from a conventional translation. Springer Nature works continuously to further the
development of tools for the production of books and on the related technologies to support the
authors.
