A mathematics book for natural science students.

Current number of pages: 261.

The always-updating PDF of the current state of the book can be found here.

A thorough README file will be written once I finish at least two complete non-intro chapters (probably intuitive approach to linear algebra and 1D real calculus).

Parts of the book are based on a course I taught in the University of Göttingen (Germany) between 2018 and 2021.
