Exercise Sheets
Each week there will be a set of problems. For each problem there will be a discussion page, and eventually we will discuss the solutions in the seminar. On request I also offer suggestions for further study.

Sage Notebooks
For selected problems I will set up a Sage playground, where you can explore the solutions to a range of problems in theoretical mechanics based on interactive Sage templates.
Participation
- extension of the wiki and requests for help
- tips and tricks concerning issues with university emails, moodle, almaweb, this wiki, etc
- general discussion, feedback, and information about you
Three are discussion forms on these pages. Viable suggestions and solutions will be promoted from the discussion to Howtos in the main part of the pages. Regular contributors will earn the right to directly edit the pages.
