Course overviewASTR 2P42 (cross-listed as PHYS 2P42) is an advanced 2nd-year course on astrophysics and cosmology. It is intended as a continuation of ASTR 1P01/02, which is an introductory 1st-year course for students of all majors. ASTR 2P42 was created for students who have suitable background knowledge in mathematics and physics and want to study the material with much more depth and detail. This course includes the following topic:
Students who wish to take ASTR 2P42 must first successfully complete the following courses:
Please note that these prerequisites are all mandatory; you will not be able to take ASTR 2P42 unless you take all of these courses first, unless you have taken an equivalent course in another university. This course may include a field trip to an observatory. More details will be posted later. Important: Announcements from the professor, containing crucial information and ongoing updates about the course, will be posted throughout the term on Microsoft Teams, in the "General" channel. To make sure you get notified of these announcements, please go to the course Teams site, click on the three dots to the right of "General", then go to "Channel notifications" and choose the option "All activity", as shown in this screenshot: (In the screenshot the channel name is "Announcements", but it works the same for any channel.) ![]() It is your responsibility to follow the announcements and read all of them thoroughly on a regular basis. No accommodations will be made for students who fail to satisfy the course requirements due to not reading the professor's announcements! |
About the professorThe professor for this course is Dr. Barak Shoshany (ħe/ħim). I did my BSc in mathematics and physics at Tel Aviv University in Israel and my MSc and PhD at Perimeter Institute for Theoretical Physics in Waterloo, Ontario. I then taught at the University of Toronto for a short time. I joined Brock University as Assistant Professor in September 2020, and I also teach scientific computing at McMaster University. I am a theoretical, mathematical, and computational physicist. My research focuses on the nature of time and causality in general relativity and quantum mechanics, as well as symbolic and high-performance scientific computing. I am particularly interested in time travel; I wrote a popular article about my research on The Conversation and was even interviewed about it on the TV show The Agenda. I'm always happy to talk about my research, and theoretical physics in general, so please feel free to ask me about it, both in and out of class! When I'm not teaching or doing research, I love composing music (look for my album "Travel Music About Time" on all music streaming services), playing video games, board games, and tabletop role-playing games, and watching TV, especially science fiction and fantasy. My office is MC E219, located in block E of the Mackenzie Chown Complex (MC). I do not have fixed office hours. You are welcome to drop by my office unannounced whenever you want, but I'm not there too often. If you would like to meet, please email me, and I would be happy to schedule a meeting in my office. |
Schedule and lecturesThe course will take place during the Winter 2023 term, from January 9 to April 7, 2023. There will be two 1.5-hour lectures every week:
There will be no lectures on Reading Week, February 20-24. Thus we will have 12 weeks of 2 lectures each, for a total of 24 lectures and 36 hours. The course will be given in person only, in the physics "library", MC B209, right next to the physics office. The course will also have a Microsoft Teams site, where students can have discussions and ask the professor questions. The professor will also use Teams to make announcements, and it is crucial that you follow these announcements closely as described above. There will not be any online lectures on Teams, only in-person lectures. Please note that according to Brock's Student Code of Conduct, "Without expressed consent from course instructors, students are not permitted to tape record, video record, or otherwise record course lectures, seminars or laboratories." If a student is caught making an audio and/or video recording of any lectures without the explicit consent of the professor, this will be considered non-academic misconduct and disciplinary action will be taken. |
Useful softwareInterested students may find the following applications useful. They are 100% free and available for Windows, Linux, macOS, Android, and iOS. Using them is optional, but might help you understand the material better.
The are also several apps that you can use in the field for astronomical observations. Sky Map is available for Android phones only, while SkyView is available both for Android and iPhone. Simply point your phone to the sky, and the app will tell you exactly what you're seeing in real time! Advanced students may be interested in Gaia Sky, a billion-star map of the Milky Way Galaxy, which also works in VR (on Windows and Linux only). |
COVID-19 guidelinesYour health and safety is very important to me! Since this course is delivered in person, all students must adhere to the following COVID-19 guidelines:
For more information on university policies, please see the COVID-19 FAQ. If you have any questions, comments, or concerns, please do not hesitate to post them on Teams! |
