Easy teacher and grader, but doesn't stick to deadlines, and often had to figure out myself when things would be due. Most stuff talked about in lecture isn't needed for the essay assignments. The assignments are pretty straightforward, and getting an A isn't hard, as long as you turn in something decent.Rate My Professors ↗

Very fun and interesting class. He had me wanting to take strong and detailed notes, despite the class not having midterms. Great speaker and decently fun writing assignments. Show up to class because there are short writing prompts every time, but they are quite easy. If you are interested in astronomy, you will enjoy this class and instructor.Rate My Professors ↗
Great professor, and I genuinely enjoyed his lectures. 5 writing assignments, but they are super easy, and the only reason I didn't get an A in this class was because I got a late penalty on an essay. There are in-class short writing assignments, so attend lectures. NO midterms and NO final. He is very engaging and explains things really well.Rate My Professors ↗
Imagine a professor who avoids grading his assignments until the last day of given instruction, does not respond to emails, and gives false information when talking about assignments directly. I think Dr. Heinz should keeping doing research, I don't doubt his skills, but he should certainly not be teaching. His performance his disappointing.Rate My Professors ↗
This class is pretty interesting and Professor Heinz is a good lecturer. You really have to go to class because he posts half of his lecture slides and the other half aren't on canvas. Also he shows a lot of videos and animations that are really helpful in class that aren't accessible outside. I recommend him, he's great.Rate My Professors ↗
