A note on communication outside ¡­

A note on communication outside the lecture and laboratory hours: we welcome any kind of feedback or questions. Specifically, do not hesitate to email us when you need help, for example when you get stuck while working on one of the problem sets. Please email both Stephan and Arne, and include as much information about the problem as possible (for example a function definition that you think should work, plus information about how you call the function and what exactly you find surprising in its behavior). For other kinds of feedback, there is also a web-based form to submit comments anonymously; everyone registered for the class should have received an email invitation to this service, with information about how to access it. If not, please contact Stephan (it would indicate that you appear to not be registered for the class).
