We will spend 4 weeks on Special Relativity, 6 weeks on General Relativity and Black Holes, and 5 weeks on Cosmology. For more details, see the Timetable.
The course will combine visualization, physical understanding, and mathematics. I will assume that you are comfortable with matrices (necessary for understanding Lorentz transformations) and with calculus (necessary for understanding metrics). The mathematics will not be fearsome (we will not be doing tensors or anything like that), but I will assume that you are the kind of person for whom mathematics helps rather than hinders understanding. If you do not fall into this category, you should consider taking one of the lower division courses ASTR 2030 Black Holes or ASTR 2010 Modern Cosmology, both of which are being taught this semester, Spring 2022.
Classes will be in-person starting on Monday Jan 24. A remote zoom option will not be available from Monday Jan 24. I do however plan to record classes, and recorded classes will be available via canvas. It sometimes takes a while to process and edit the recording, but my intention is to have the recording posted to canvas hopefully on the same day as the lecture. The canvas recordings are behind the CU firewall, accessible only to people in the class. By participating in the class, either in person or remotely, you agree to have your participation (image and audio) recorded. CU rules prohibit you from recording the class separately.
We will follow state and CU guidelines COVID-19 Information. Colorado mandates that masks are required indoors in public spaces, which includes in class.
There will be a tendency for problem sets to be more mathematical than exams or group projects.
Only the best 6 of 7 problem sets will count for grade.
Projects will be take place in class. Each project will take place during a full class period. For the project, you will assemble into groups of 3 or 4. You should immediately assign one of your group to be the “Scribe”. The group should discuss and solve the project together.
It is the Scribe's responsibility to write up the results obtained by the group, and to upload them to canvas at the end of class. I will accept only one submission from each group. The write-up must include the name of the Scribe, and the names of all the other members of the group.
Only the best 2 of 3 projects will count to your project grade. This is so that you can be unavailable for any one project without penalty. There are no project make-ups, since the whole idea of projects is to work in teams.
The exams will cover material discussed in class, and will consist largely of short answer or short essay questions. The two midterms will cover material covered in the previous 4 and 6 weeks respectively. The final will cover all material covered cumulatively during the semester, with an emphasis on the final 5 weeks.
There will be summary sessions prior to each exam.
Item | Weight |

Problem Sets | 3/8 |
Projects | 1/8 |
Midterm 1 | 1/8 |
Midterm 2 | 1/8 |
Final | 2/8 |
To have your iClicker scores counted while classes are remote (first two weeks), you must Set up a free iClicker Student Account. Use iClicker to record your iClicker responses remotely from your cellphone or laptop. iClicker will request your institution, which is University of Colorado Boulder, and the course name, which is Relativity and Cosmology. The instructor name is Andrew Hamilton.
To use an iClicker in class when in-person classes resume, you must purchase an iClicker, and Add an iClicker Remote ID to a Student Account.
Clicker questions will generally be of two kinds:
You win clicker points as follows:
Points | Assessment |
---|---|
0 | No answer |
1 | Wrong answer |
2 | Right answer |
It is strictly forbidden to operate someone else's clicker for them. If you are discovered doing this, then both you and the person whose clicker you operated will receive an F. If you see a classmate operating two or more clickers, please bring it immediately to my attention.
If you have a temporary medical condition or injury, see Temporary Medical Conditions, and discuss your needs with me.
