Course organization

Virtual and physical participation for all components the course will be made possible. Late enrollment/registration is also possible (immediate participation is welcome if registration is anticpated).

Grading: 30% project, 25% homework, 18% midterm (in class, Oct 20), 18% final (in class, Dec 6th), 9% quizzes may be subject to upwards curve

Projects: Submit initial proposal by Oct 11, revisions may be requested and will be due Oct 27. Projects related to ongoing investigations or overlapping with other courses are encouraged, so long as they have some component related to this course. A project poster session will be held on Dec 1st and reports are due on Dec 13th.

Slides and notes are based on the Fall 2015 slides by Michael T. Heath. Resources relevant to the course are available also on the old course webpage by Prof. Heath. See also the previous course webpage.
