Comment: You read some online articles about the science and engineering behind cooking and discuss them every week. Prof Muller is really nice and smart ( took us to pizza one week) and it's superb being in a small class ( ~14 people).

Comment: I thought she was a great professor. She was a great lecturer and was very helpful in office hours. Homework assignments were sometimes impossible to do without the solutions, even though she fully expected us to be able to complete the homework without looking at the solutions. The midterms were reasonable but were a huge time crunch. The final... wow, where to begin. Not sure what went down during those three hours. It was by far the toughest final that I've ever taken. The GSI's and instructor showed no mercy when writing that final. Overall though, I enjoyed the class, and I'll definitely miss listening to Professor Muller's lectures.

Comment: Professor Muller was a very good lecturer who managed to make a general engineering class relevant and pertinent for chemical engineering. For the most part, her lectures were useful, though they often went through lengthy derivations that we didn't really need to know, as long as we understood the end result. She was good at relating new concepts to previous examples, often deriving new formulas by comparison to old derivations, which helped tie the class together. The first 2/3 of the class on mass transfer was relatively straight-forward, just a table of equations applied to a bunch of contrived situations of fluid flow. The last 1/3 of the class on heat transfer was pretty challenging, since there are way more equations and we had very few practice problems to work on. Note: the GSIs are in charge of problem sets and exams, which were inconsistent. Often the problem sets were so challenging that there was no hope of actually doing them without the solutions. The midterms were reasonable and fair, though the final was possibly the most demoralizing exam I have ever taken at Berkeley. This is not prof. Muller's fault, so hopefully future classes will have better GSIs.

Comment: Great lady. Really intelligent, knows the material in and out. However, the exams, particularly the final, were not kind, and neither was the curve. The first two portions of the class, momentum transfer and velocity profiles, are not too bad - just make sure you practice. Problem sets, previous exams, problems from discussion. The last portion of the class, heat transfer, was the worst because we received close to no practice (the three problem sets did not cover the material fully), yet the final exam was nearly 100% heat transfer. I don't think I've ever taken a final that difficult apart from the horror that was Chem 4A. The curve was not nice at all - a lot of people ended up with B-'s and C's. Overall the material in this class is not too conceptually difficult, but the exams, which comprise about 85-90% of your grade, make it so.

Comment: Note: I may be significantly biased in my class experience because I did not take 141 simultaneously, and had more time to devote to 150A. Professor Muller is an excellent instructor, especially for the fluid mechanics section of the class. Her lectures on fluids were clear and concise, and she provided some useful examples... followed the textbook closely, but no arguments here. The material at the beginning of the class is straightforward and "easy," but the exams reward only people who can do the calculations FAST. The second part of the class looks like terrifying multivariable calculus, but Muller never made us use the heavy Math 53 techniques, and 90% of the time the problems can be reduced to single-variable calculus. It's more important to be careful than fast in this section, and 3d visualization helps. Many of us felt that the last sections, on turbulent flow and heat transfer, were less well taught. Part of that has to do with the derivations presented in lecture, which have almost nothing to do with the way we actually solve problems on assignments and exams. That's kind of the way engineering classes work, but some clarifying on the teaching staff's part would be nice. Professor Muller's office hours can be incredibly helpful, and addressed most of my concerns (would have gotten to them all if there were more time). Assignments were usually fair, but every so often a wild troll problem would appear and use "we never covered this in lecture" for multiple critical hits. Between GSI office hour stampedes and your trusty study group, these will turn out alright. I felt that a slight increase in the homework load would have provided useful exam practice, but we could always find new problems on our own if really necessary. Exams: cheat sheets and the provided equation sheets are beacons of hope. My best advice is to know what is on them and practice getting at it, rather than memorizing the details themselves, so you can get at it FAST if necessary. I can't overemphasize the speed factor. Best of luck to you!

Comment: On the surface, Muller may seem like a sweet grandmother, someone who might have baked everyone snickerdoodles for today's lecture. But then lecture starts and you see calculus and physics and tons of seemingly unfollowable formulas and it leaves you dumbfounded. She has a definite youth to her, she seems a lot more relatable than any other professor I've had before; she enjoys poking fun at students, but not in a cruel or demeaning way, just usually when something odd happens like a student walking in late, handing in homework, and subsequently leaving without a word. It makes it very easy to learn from her, since she's got a constant smile on her face and it's undeniably a professor standing in front of you, but at times feels like another fellow student. The class is definitely more Physics-based, heavily reminiscent of 7A during the first couple of weeks, but then you start using integrals and a few more formulas. Largely based on Math 53, in that it mainly deals with tracking fluid motion in multivariable settings (does the fluid flow radially? does that depend on theta?). Assumptions are everything, and sometimes it comes down to simplifications you didn't think could be made. Standard problem sets, take a long while; try to start them early. Exams, as others have said, aren't big time crunches, and while you may not be able to finish EVERYTHING, it makes the grading scale less swingy since you can truly demonstrate what you know (or how lucky you are). There will always be a new twist on a problem; I can't count how many times I've opened the book to an assigned Denn problem and gone "what the **** is this?". Probably not a class JUST for ChemEs, as the Chem element played a minor, if not nonexistent, role in problem solving. Definitely for the more Physics/Engineering-minded.

Comment: Not an overly difficult class. Muller was very clear on explaining concepts and basically lectured straight from the Denn book but reinforced unclear topics well. Muller's lectures were very well organised but a bit math involved sometimes during derivations (especially during the Navier-Stokes,momentum, heat transfer eqns) She would clown on students who walked in (I loved it when she did that) and would throw in an engineering joke occasionally which was most welcome. The homework problem sets took HOURS to complete and by the time you were done, it was often 2AM Friday morning. But all the sets reinforced crucial concepts. As with all ChemE classes, working in small groups helped a ton as the collective brain is better than the individual. Of course, working on the problems by yourself before is highly encouraged as you wont have others to help you on midterms and final and you learn a lot more from figuring out what you did wrong and how you thought of a problem wrong by doing them yourself. The midterms were not all that difficult, but were still somewhat time-crunched. I absolutely loved the Denn book for the fluid mechanics part of the class. It was easy to read and the derivations for equations were simple to follow (if not a bit long). It stressed the important concepts of fluid mechanics without getting bogged down in the math. Same goes for the heat trasnfer WWWR book. If its one thing I've learned from 150A, its everything in chemical engineering comes down to the assumptions you make at the beginning of a problem and properly defined boundary conditions. The feeling of completing a problem in this class has no bounds (see what I did there lol) GSI's were helpful during office hours. This class comes down to knowing when to use particular equations and how to apply them with certain conditions (thats basically an entire third of the class). At the end of the class you'll see why heat transfer is part of 150A and how it relates to the fluid mechanics part of the course. Good luck in 150A!! Long live Dead ChemE's!!!

Comment: As far as engineering professors go, Muller is probably one of the best I've ever had. Her lectures are really well-organized and logical, she goes through derivations and concepts logically and clearly, albeit a bit too quickly (it helps a lot to go through each lecture's material right after to understand). The material is pretty math-heavy and can be a bit dry but she throws in the odd joke here and there. There's weekly problem sets that can take a pretty long time, it helps to go to office hours and start early, they're actually pretty helpful for learning the material. Midterms are actually ok, they're based off of the big concepts from lecture/textbook. There will be slight twists in each problem that haven't been covered in the HW/lecture, but the problems are definitely solvable if you have at least a somewhat solid understanding of the material. Midterms are definitely fair and not as time-crunched as others *COUGH CHEM E 141*. Discussions can be helpful depending on GSI.

Comment: Muller is an awesome little old lady with a great sense of humor. She's a complete boss, effortlessly solving heat transfer problems. Homeworks were VERY tedious but doable. Exams were fair, but very speed-oriented due to the material not being hard to grasp. Definitely one of the better classes I've taken at Berkeley. As a non-ChemE major, I would recommend taking this class!

Comment: She's a very clear lecturer, goes over the material very well. Somewhat time crunched especially with less classes due to budget cuts, especially at end. She's this little old lady that just lectures very well and knows the material. Personally i thought the class and material itself wasn't that difficult, but when it comes to exams, its about knowing the material very quickly and being able to do a lot in under 1 hour.

Comment: One of the best professors I've had so far, she's very clear about the material and she's comfortable teaching the subject. Still it's not an easy course so you can't really blame the professor for that.

Comment: Muller is a very clear lecturer and has a wry wit to boot. The heat transfer portion of the course gets rushed and condensed however. The second midterm is clearly made intentionally overlong which tends to emphasize test-tasting strategy over understanding. The first midterm and final are tough but fair.
