PHYS 515 :: Physics Illinois :: University of Illinois at Urbana-Champaign


Lectures will take place on Mondays from 17:00pm - 18:20pm and on Wednesdays from 17:10pm - 18:30pm (after the Physics colloquium) in 162 Noyes Laboratory.
Recordings of the lectures will be posted on mediaspace.

Homework sets will be made available on Wednesdays before the lecture, starting in week 2, on this website. They are due on the following Wednesday before 11:55pm Central US and they have to be submitted via my.physics.
In general, you are allowed to use computer algebra software, like Maple or Mathematica, unless stated otherwise. If you do use computer algebra software, together with your PDF solution, you must provide a well-formatted print out of your code. Under no circumstances are you allowed to use a computer algebra package, such as grTensor or xTensor, to calculate tensorial quantities.

During the Lecture you will engage with the material by answering conceptual questions via Gradescope, Entry code: K3X8X8. This will give you bonus points for the course.

If you have any issues logging in to view any of the secured documents below, please try adding "uofi\" (without the quotes) in front of your netid.
