I already took a fiat lux class about astronomy with Professor Rich but knowing he was teaching another made me want to take another one. He is a really nice professor, and if very passionate about the subject, which is great to see from a professor. I enjoyed every lecture, and some were coincidentally similar to what I was learning for fun on the side (such as how to tell what atmospheres of different planets are made of). This class was really cool, and I would definitely recommend taking it if you like astronomy. I did feel bad, though, when only myself and another person or two showed up despite the class being enrolled by 15+, please go to class, it's a fun subject and it makes the prof happy to see people engaged!
