Although rigor is part of my teaching, the course takes place in a very relaxed atmosphere where a discussion takes place between the student and me rather than a one-sided transmission of knowledge. In addition, I offer help for using the following programming languages: Python, Java, C (++), Julia, Matlab, Shell
