Your turn! Student Projects

As per the syllabus, 10% of your grade will be based on contributing a Rhea page on a subject of your choice. To pick a subject suggested below, simply write your name next to it. (See above how to edit this page).


  • No more than four people per subject.
  • Do not remove other's people's names from projects. Rhea keeps score of edits; this is not anonymous.

Your project page will be graded based on content and presentation. Describe the subject as you see it, and report what you find interesting. Feel free to add examples, computations, etc. Links to other sources and related subjects will improve the score. Do not simply copy a book or webpage and do not plagiarize. Use your own words to say what you want to say, don't paste other people's work without acknowledging explicitly. Read Rhea's copyright policy before proceeding.

Required components: see the syllabus.

For some lovely contributions, see Honors Project 2011 by Daniel Lee.

Deadline: Sunday before finals week, December 2nd. No changes after that will be taken into account.
