Professor Williams is definitely THE PROFESSOR that you should take EE101 with. At first he seems a little serious, but later on you can tell that he is a pretty easy going person. Furthermore, he always ask students if they have any questions, on top of that, he also seems very passionate about answering some of those questions. Overall the course is thoroughly taught and his lecture notes are also well organized.

This class is hard but you do learn a lot. Williams knows his stuff forwards and backwards...I swear this dude dreams E&M, and he can answer almost any question people come up with with literally 0 hand waving. He is incredibly clear (although a bit stern) and runs a tight, manageable class. If you are an EE looking to learn about EM, take this class. If you are looking for an easy tech breadth class, do not take this.

Just writing his notes, plus too many words instead of equations. Could have just printed out the stuff before the class and explain it in details during the class.

Professor Williams is a great lecturer who gives lots of good intuition and examples for pretty difficult subjects. I would definitely recommend taking him for 2H, because I think it really gives you a strong basis for all of semiconductor classes. Don't be scared off by the honors part, it's really not that much more work than a normal class and the grading is actually more generous.

Professor Williams is one of the clearest lecturers I've encountered so far in the ECE department. His lectures are pretty well structured and could give students a good perspective of how semiconductors work. However, I found the materials to be a little bit dry since I personally did not find semiconductors to be an interesting subject. Aside from that, simply judging this class by the effectiveness of the professor's teaching, I would say this class contains extremely important knowledge, and could be a fun experience for some students. This class consisted of four quizzes and a final paper (no final exam nor midterms) for my quarter due to Covid, which may seem like more work than typical quarters. However, the grading scheme is pretty generous, and as long as students put in the work, getting a good grade wouldn't be an issue.

Prof Williams is a pretty good lecturer and explains concepts really well for an intro class. Instead of a midterm and final, we had ~weekly homework (7 total, dropping lowest score), 4 quizzes (every 2 weeks) and a final paper. The quizzes were hard, but his overall grading is pretty lenient. I got a 50% on one of my quizzes when the average was a 90 and still ended up with an A-. The final paper had you write 2 pages about any topic relating to the class. Would recommend

Professor Williams is a really good professor for this course. Personally, I had a miserable workload for this quarter, so I wasn't able to pay as much attention to the course as I had hoped, because the material is actually interesting to me (don't take this course if you really aren't interested in semiconductor physics and E&M principles because you will hate it). The final project (presentation and paper) was pretty strict in terms of requirements (time limit, formatting, etc.), but the grading isn't particularly harsh as long as you don't miss large sections of your chosen topic. The lectures are a little bit dry, which is not the worst, but the textbook is atrocious. I managed to find a pdf and none of the equations are properly written out (slashes for division, Greek variables missing in some eqns, and missing parentheses).

Overall, if you find solar cells and semiconductor physics interesting, you'll have a decent time here. Otherwise, don't bother because the photonics series really isn't worth it for anyone who isn't very into it

Professor Williams is a phenomenal guy. He puts a lot of efforts in explaining the concepts and try his best to make everyone understood the lecture. He often uses interactive methods to explain the dauntingly difficult topics. The class had 5 HW assignment (somewhat difficult but late submission was allowed), 3 quizzes (Easy), and a review paper (on any topic related to QM) & short presentation.
I couldn't score well in the class due to personal reasons, but he graded leniently. Overall, the class was informative and engaging even to somebody like me who had no prior experience in QM. I would highly recommend this class.
