Comment: Not a very good lecturer. Very disorganized and he tends to wander through topics. Not very helpful on understanding. any of the content. GSI was incredibly helpful and absolutly necessary to do well.

Comment: Lectures are disorganized - Rich does not know what he is teaching or is simply unprepared. Should have realized lectures were a lost cause by the second week. Grading was extremely inconsistent. Almost identical work could receive up to 50% different scores. No grading rubric or answer key even with multiple student requests. Final Exam was totally random and with some problems nobody expected.

Comment: Very enthusiastic and adorable, but he spends some lectures on *one* example and others repeating what he said the previous day. Homework and tests are pretty fair, and tests are open book and notes.

Comment: Ok, so maybe lectures weren't the most helpful and you're better off reading the book, but Pello is just so enthusiastic about teaching and he just wants you to understand. All exams are open book, open note, open laptop, open call your mom and ask her what she thinks...yeah. They're all more of a time crunch than actually difficult.

Comment: Personally, I think these ratings are way too low. Looking back, I liked him because he used common sense. Professor Chen could have easily spent lectures going over mathematical details or asked us to prove things that are essentially just exercises with little application. Or, he could have been overly concerned with abstract concepts that we were really not mature enough to *truly* understand in an intro class...but he wasn't. He was concerned that we understood conservation of energy, conservation of mass, and know how basic steady-state systems work. Was he tough? Eh.... haha. Kinda. The averages were about 20/30 for each quiz (5 of them). There were no "midterms." I'm sure everyone thought the final was hard......... but what else is new? P.S. I'm not sure if this was intended, but some of the "numbers" he threw out in lecture tended to be answers to quiz problems (i.e. if he says something is 30% efficient, then you might end up with an answer of 28.9% efficiency). The mysteries of Cal.

Comment: If you want to learn thermodynamics, don't take this class with Rich. Didn't learn anything in lecture. Quiz problems he gives don't make sense. The only positive side to his class is no homework, so you can cram everyday before a quiz and still pull a decent grade. The book is amazing for this class, taught me everything I know (don't know) about thermodynamics.

Comment: Frenklach teaches this class using Matlab to perform tedious work rather than having to look up stuff on steam tables. However his exams have some stuff that are barely relevant to the homeworks. Lecture delivery were neither particularly special nor particularly poor.

Comment: Great professor; Prof. Frenklach teaches thermo a little differently than others, but he really stresses what's important and makes lectures worth going to. Homework leans heavily on MATLAB programming, which is not the norm. Though the hw was long at times and frustrating if you messed up syntax, it's actually on stuff we might see in the future (a turbine vs. something that would never happen in real life). Exams tested what people knew really well, so paying attention in class is important here. He receives every question well, and he is fine with explaining things more thoroughly if needed. Overall, pretty awesome.

Comment: I actually took this in the summer of 2013 with another lecturer, Dr. Rich. For a lecturer, he's alright. He owns his own company that deals with problems concerning thermodynamics such as the causes of fires. So it was pretty interesting to learn about how these topics relate to situations encountered in industry. He was a bit unorganized at times and I felt that some of his lectures were winged, but nevertheless, he still did a pretty good job. I learned quite a lot. HW was ungraded. There were 8 quizzes and one final exam. A lot of material was covered so that's why it was a 10 week course.
