Fall 2018 - Hamilton is a standard professor - he goes over concepts/theory in class along with some examples. I liked how he did in-class questions through a software called Kudu - this allowed us to interact with each other and not fall asleep at 9 am haha. However, I found that his lectures lacked example problems, and also he did not give us any sample exam problems before the midterm/final. As such, we kind of went into the exams without knowing exactly what to study. Also, some of the hw questions he assigned were kind of irrelevant to the material. Overall, Hamilton is okay as a professor - I'm kind of neutral about recommending or not recommending him.
Spring 2018 - 4AL is a behemoth. You've probably heard that the grading is harsh and that you're going to spend a lot of time on lab reports. It's true. . You're given all the materials required for this class (a lab manual) and you go to section having read up on what you are going to do in lab. The labs investigate different physical properties like mechanical energy, friction, gravity etc. Most labs (not lab reports) I was able to finish in two hours. However, the last one I had to do twice because I ran out of time. Make sure to collect good lab data. . The TA's are instructed to deduct a lot of points for mistakes to spread out the sections, as there are up to 20 kids in a class. Homework 0 (the first assignment) covers the policies of the course. The next 7 labs will take you at least 10 hours to perfect (to get a good grade), re-reading and editing to the specifications of your TA. You'll learn when you get your old labs back what the TA was looking for and should correct for it. Put in the time and hope you come out on top when it's all said and done.
Fall 2021 - He's okay. Not particularly great, but not bad either. The homework problems are mostly algebra (despite the fact that TAs were okay with calculation software) and were quite uninteresting. The final exam and the second midterm had some fun problems. The content of the course is extremely exciting, though Prof. Hamilton doesn't have the infectious enthusiasm of many other QM professors. Griffith's QM, the textbook, is as terrible, but Shankar's book and Youtube will help you a lot.
