A mathematics book for natural science students.
Current number of pages: 273.
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.
