Laboratory Exercises
Attendance during the Lab period is mandatory to receive credit for the exercise. Exercises are due one week after the lab period. Make-ups are ONLY allowed by making advance arrangements through the Office of Studies. Late work will not be accepted.
Lab Exercises are subject to change without notice and may be updated the week of the lab exercise.
Problem Sets
Problem sets are due one week after being assigned. Make-ups are ONLY allowed by making advance arrangements through the Office of Studies. Late work will be penalized no less than 25%.
Extra Credit:
Every Friday at 3:30 pm in Room 301 Locy Hall, the EPS Department
hosts a speaker who discusses current research.
The list of speakers, titles, and dates
is here. While
not all the speakers cover topics directly relating to this course, we offer homework extra credit for a 2-page summary of each talk. This extra credit
is due two weeks after the talk. This option also applies to talks in the
physics department on "Is the solar system stable?" (Thursday, January 7 at 4:00 PM
Ryan Auditorium, Tech) and "Extrasolar planets" (Friday, Feb 5 at 4:00 PM in Tech LR 2)
