Comment: Was a really enjoyable class. Without some background knowledge in physics this class would be relatively tough due to the sheer amount of material covered, but for myself it was a perfect way to increase and fill in the gaps in my knowledge. Lectures were extremely well webcast. Would definitely recommend to satisfy a physical science breadth.

Comment: The first midterm was a take-home midterm and very straight-forward. The second was also very straight-forward. I pass-no-passed the class so I stopped going to class the last month because I had an A- and still ended up passing the class. The final was hard though--although I'm pretty sure it's because I didn't go to class the last month. He's a really nice professor though with some of the easiest midterm questions I've ever seen. Do his old midterms/finals and learn those specific concepts and you'll be fine.

Comment: Cool prof. Very passionate about the material and really cares about students understanding it. Used a lot of calculus-based derivation in class which were confusing at times, but he usually explained things fairly clearly. Mastering physics is a horrible homework system where you only enter the answer and it tells you if you're right or wrong (and you have a certain number of tries to get it right) but it's a very small percent of your grade. Helpful in office hours, though they were a little crowded (only 1 hour per week) and it was intimidating at times because he would ask students to work the problems they had trouble with up on the board in front of everyone and show where they got stuck. First two midterms were a little tricky, though they had a few problems that were math-heavy. Final was impossible. Overall a really good prof who genuinely cares about teaching and is approachable.

Comment: Run of the mill Physics 7A class. Stahler was never particularly outstanding, for better or worse, and neither was any of the lab/discussion material. Homework is done through Mastering Physics, which is a particularly finicky online submission service, but the individual problems were generally straightforward. The first two exams were more or less fair, but the final was exceptionally difficult, especially compared with the overall easiness of every other exam and assignment. Overall, adequate 7A professor choice.

Comment: Mastering Physics is well, mastering physics. It was pretty time consuming, and not heavily weighted in the course. Stahler was a pretty cool guy, lectures sometimes were dull, but they helped get a bigger picture of things. His exams were okay, except the final. Felt the final was pretty difficult compared to the other two tests.

Comment: Stahler is definitely a very interesting lecturer, but in lecture he'll often go beyond the textbook and do unnecessary proofs and derivations that may show you where all the equations come from, but are often so tedious and difficult that no one has any idea what he's doing. I definitely recommend going to office hours to get to know the professor better (which is hard in a class of 200). 7A covers a lot of ground, so in office hours he'll be able to supplement lecture with what he doesn't have time to say and do examples from the homework or go over exam questions. MasteringPhysics is literally the problems at the end of each chapter with randomized numbers so that you don't copy answers directly from your peers. Honestly, the best way to understand the material and prepare for exams is to do every problem in the back of the chapter, not just the 10 you are assigned weekly. The exams got progressively harder, with the medians on Midterm 1, Midterm 2, and the Final being 74, 65, and 52 respectively. The final was insanely hard, but your grade was saved by the curve. This course is very difficult, but you certainly learn a lot. You'll find that no matter how hard you though your honors/AP/IB physics class in high school was, it was all really just plugging in numbers into formulae. Physics 7A will teach you how to think.

Comment: Great guy who wants you to succeed and understand physics. His lectures are all proofs and sometimes demonstrations, which may or may not help you. He's extremely helpful during office hours, so make sure you schedule one right before an exam. Speaking of which, the exams were more difficult than the homework, but they're very straightforward. Bottom line: take 7A with Stahler if you can!

Comment: Lectures were fairly helpful but the examples shown were more focused on the math rather than the physics. But overall, he explains things pretty well. Funny and enjoyable lectures most of the time. Exam averages dropped like 20 points each time. The final had a 57 average I believe. So his exams are fairly difficult but still doable.

Comment: Puts in the effort to show the math behind physics. But honestly, that kind of thing should be spent on self-studying, not lecturing. Lecture should focus on physical understanding. As a result, the focus of the class gets derailed a lot in lecture, but proofs were interesting nonetheless. Fair exams, they are creative and interesting in retrospect. Professor really wants students to learn, so go to his office hours.

Comment: Genuinely cares about his students and wants to teach the material effectively, and does so in an entertaining way whenever possible. Unfortunately, too much of the lecture is focused on math heavy proofs which are hard to follow and ultimately unnecessary. His first midterm was easy but his second midterm and final were difficult. While most of the exam is fair, a few problems are thrown in to lower exam grades and are hard to the point that studying almost seems futile.

Comment: Stahler is an okay lecturer, he is very enthusiastic but his lectures emphasize proofs a lot and can be difficult to learn from if you haven't already read the book. He gives some cool presentations, but you can get by without going to lecture if you stay on top of the homework. Tests could be a little tricky but were pretty easy, especially if you make good note sheets (include examples from the book!).

Comment: Stahler's first semester of Physics 7B was a pretty good one, in my opinion. Lectures are mostly, if not at times entirely, geared towards proving formulas rather than problem solving, so you may be left to die while doing MasteringPhysics (section may help at times, though, although the workbook mostly asks you conceptual questions, and every single answer on Stahler's exams is going to be a number) and his exams, although the latter can definitely be rectified since he allows note pages (like in 7A) and copying down the book examples works WONDERS. The class is split into 3 distinct parts: thermo, electricity, and magnetism. Thermo should be very manageable, at the beginning there's a bit of kinetic theory which absolutely never showed its fact on the midterm or on the final, and the rest is heat/work cycles which you may have had some exposure to beforehand (I'm looking at you, Chem 4A). He also loves questions involving the formula Q = m * c * ΔT which I definitely remember doing dozens of times in high school, so that third of the class should be manageable with a few correctly placed formulas on the note page. Electricity (and magnetism) is a much larger step up, because it's largely conceptual, and a bit difficult to grasp once Gauss's law comes around. It also marks the beginning of the use of calculus in Physics (we did it a bit in 7A, but to almost no extent)... circuitry may be recognizeable from high school Physics but it doesn't last long. Stahler's exams tend to be on the easy side -- I went from landing under 20/100 in Yildiz's 7A to 79/100 on Stahler's Thermo exam. It certainly depends on which side of Physics you enjoy, but Stahler makes it a lot less daunting.

Comment: As NC won't let me rate the Physics 49 course I took for 7B, I'll do it here. I only took the heat/thermo part of the class as Physics 49. Lots of derivations during Stahler's lectures which were a bit dry but then again heat/thermo is already dry (see what I did there? ;D). As usual, mastering physics was a pain, but working with other people gets it done a lot faster. If you don't go to lecture, reading the book (Giancoli) and doing problems in mastering physics should be more than enough to get you through (at least for the heat/thermo parts) For heat/thermo I feel a key to the class and the study of heat/thermo is that things should obviously "make sense." Look at temperatures and entropy and various other changes in physical quantities and ask yourself if the values make sense. You know you're doing something wrong if you dump a small ice cube in a small thermos and its final temperature is like -100 degrees C. Theres really not much to the course. Midterm was fair and I only had to do the thermo lab and 1 question off of the final which was awesome. Good Luck with whatever you take 7B as!!

Comment: He is a very enthusiastic professor. He did a very excellent job during thermodynamics with both derivations and the technique for solving problems. His E&M was also very good albeit a little more confusing, probably due to the subject matter. The Homework is just mastering physics, it is the same regardless of professor. It just takes a while.

Comment: Apparently Stahler usually teaches Physics 7A/7B so he's used to teaching formulas, but I think he did really well making this class non-math focused. He's very enthusiastic and uses a ton of interesting demonstrations in class, so it's worth it to go to lecture. I learned a lot about how physics applies to our everyday lives and I really enjoyed this class. The only downside was that I couldn't always wake up for lecture in Pimentel so I watched a lot of webcasts. Stahler uses weekly pop quizzes to grade participation and I missed many of them, so my quiz grade was a 30%. The exams were mostly multiple choice with a couple of short answers, overall pretty straightforward but a couple of questions are sometimes badly worded. The curve is very generous so you don't have to worry too much about your grade--the average on midterms was usually around a 60%, roughly a B. My final grade was 75% and I got an A in the class.

Comment: Whatever math he doesn't include in his physics class (a good thing), he makes up with lively demonstrations every lecture about the already very interesting topics he covers. He clearly showed me that physics is not the far-removed esoteric stuff only for scholars, but knowledge that is relevant to our daily lives. He actually made me like physics. On top of that, he's a very clear lecturer, who is also willing to answer questions. His exams are very reasonable. He wants all his short answer questions answered in two sentences: if you know the material, you get the grade easily and quickly. His questions are clear and concise, he goes through every question that was tough or unclear, and he tries his best to improve as an instructor. Although they're difficult, they're curved as well, so you don't have to worry about your grade if you study (since most people don't). I especially loved how he allowed students to prepare "cheatsheets" of notes for every midterm and final. That policy made it clear that his point was not to cut your grade for every detail you forget to prepare for, but have you not worry about tiny specifics once you have the big picture in mind. If you're taking this course P/NP, it's very easy to pass, but if you're taking this course letter grade, be warned that his homeworks take a lot of time. Every week he wants you to summarize a news article relevant to the chapter he's teaching and explain the physics behind it. His GSIs grade his homeworks on a scale of 0-3. Most people, who do not too bad a job, only get 2's...so if you want a 3, be prepared to put in two or three hours.

Comment: To any non-science and/or non-math people like me looking to fulfill a physical science breadth: TAKE THIS CLASS. The concepts in this class were so hard for me to understand, but Stahler is super caring about his students, and he wants everyone to do well. I didn't have a very helpful GSI which was pretty frustrating, but just study with some friends and you'll be fine. Stahler does a full class curve at the end of the year, I had a 59% before the final, got an 80% on the final, and ended the class with a B+. Most students will get a B regardless of your scores on the exams. Make sure to keep up with readings! He quizzes and tests on things not covered in lecture.
