Fall 2022 - ngl most recent review is completely wrong lol. This was quite hard compared to 105D with Lavine at least. It was similar in content except he derived everything in a more convoluted way often with a lot of mistakes and missed steps. Also he would stand directly in front of the board while writing and then just stand and stare at it after he finished so it was difficult to follow along. It went a bit beyond 105D in content but it's mostly just additional formulas and methods to use for a wider range of problems. Dhir had a few jokes but he is not the friendliest since he often had some snappy responses to people answering his questions incorrectly. He had a hard time understanding people's questions since the material is so easy to him. Homeworks (15%) were only a few questions but holy hell they are complex. They were beyond the class material, and it was annoying to spend so much time interpolating tables to find properties to use. Make sure you use your resources *wink*. He lectures on derivations a lot but just tune that out because you don't need to know it (and you won't learn them successfully anyway unless you go to the TA (shoutout Atindra the goat) ). Open note tests are nice, but the final was a little challenging (50% final, 25% midterm). There is a group design project (10%) that is annoying but it's really just a long homework problem. TA was very helpful for that. I wouldn't really recommend this class but you'll survive it if you have to.

Professor Marner's 131 was an amazing course, even though heat transfer is my least favorite topic. He is a very smart professor and is very good at simplifying the complex. His class is tough and it is a lot of work, but Marner is by far the best professor I have had at UCLA. He makes you fill out notecards with your name and some facts about yourself and uses them to call on students during class. He does this so you pay attention, and so he can learn everyone by name. The questions he ask are not usually that tough and he is perfectly fine if you do not know the answer. There are two group projects, which are relatively easy, especially because the class was half graduate students and each group got one of them. Along with tons of engineering knowledge his brain is full of interesting life stories and wisdom.

Sure Mills puts up projector slides directly from the BHMT book he wrote, but some professors from other universities have done the same. His BHMT book is excellent and well written, I liked his style of writing. The concepts were in good order, and the text is not as lengthy as Incroprera and Dewitt. The problem sets are challenging. If you don't read the book regularly or in advance, you might not find the lectures useful. Too bad the lectures are usually at 8AM. Go to office hours; Mills will help you and have good conversations with you. You can ask him homework questions in office hours and he will help you think of the correct approach, but stop and not give you the solution. He especially likes it when you talk to him about anything else. If you go often enough, he'll remember your name. Once in OH, he told me there a problem in the book was a good exam question, and then it showed up on the final exam! Mills may seem intimidating, but he is actually friendly once you get to know him. Take his courses if you can! He also was the coauthor of the MAE 157 lab manual, which was also well written.

Fall 2019 - Pilon is a great guy, but this class was kinda tough for me. He's very particular about everyone being in class on time, no phones in class, etc. It's the exact same as 105D, but with a lot more math involved. He likes to focus on the derivations and proofs of the heat transfer equations, which I wasn't a fan of. The homework took a lot of time every week; without Chegg I would have been screwed. The exams weren't terrible, as long as you understand the fundamentals of the class and not just the equations. The project at the end of the quarter takes a long time, but it's pretty interesting and overall not too bad. I'd recommend taking this class just to get to know Pilon, but the math-emphasis diminished my interest in heat transfer.
