I am not a student now but I attended Cal Ply and graduated in 1989 The Class I tokk with him was Heat Transfer (I Beleve it Was ME-113) To me He was my best teacher I ever had in my entire life. the way he presented the class very organized and neat. and excellent in reviewing covererd material prior to testing. I would hear stories of hime being a difficult teacher But to me he was a fair teacher and very helpful when you had question I will always remember him as the best ever.

Mulleson is a really nice guy, if you go to office hours he will bother to learn your name. He is a great teacher, makes sure the whole clase understands before he moves on. The homework is moderate as are the tests, i's not cake, but not impossible either, try to take him if you can.

Mullisen is an awesome professor. He knows the material really well and does an amazing job teaching it to the students. The only problem is that he is retired so he only teaches one or two classes a year. If he happens to be teaching the quarter you are taking it definitely take it with Mullisen.

I can only say one thing. Ron Mullisen was the best professor I've had at poly. Hands down. He was funny, nice, approachable, stinking cute, and just a joy to be around. He understood student difficulty and after the first test (the average was a 50), he made the second one super manageable. I got the highest grade on a test in college on that test and deserved it after the work I put in. He is amazing, take him!

pretty straightforward class. go to lecture, do the homeworks, you'll be fine for the midterm. he makes you do experiments from his own textbook; i would recommend splitting the cost with a bunch of people and make a Drive folder of all the data bc you only use 1/4 of the book. very nice, charismatic old man. made thermo seem easy. in office hours, however, he had a few issues recognizing my problems. not a terrible thing, just expect to spend more time in OH than normal (5 min vs 30 min)

There isn't a whole lot of content in this class, and Professor Mullisen does a pretty good job of developing it on the board. The homework is also pretty good at reflecting the lecture material. There are a few things that Mullisen thinks are really important, like vapor quality, 1st and 2nd laws (duh), P-V and T-s diagrams and using the thermo tables, so make sure before the test you absolutely know how to do these things. Also, the exams are open book / notes / internet, so make a notes sheet with just the equations you need and bring the textbook for the tables. The exams are pretty straightfoward and only 3 questions (sans the final), but there's a lot to keep track of when doing a thermo problem. The experiments take a bit of work to do well, but it's not that hard (just manipulating data with Excel) and interesting if you skim the experiment data from the experiment book. experiments

Mullisen is extremely smart. Also, easily one of my favorite professors so far at Cal Poly. He presents the material very clearly, and obviously has a very in depth knowledge of the material. He is really nice, and he doesn't try to trick you on the exams. The entire course grade is broken down into 2 midterms, 1 final, and about 5-10 "experiments" which are basically short lab reports written with data that he collects and distributes to the class. To do well in this class you need to keep up with the homework, because he doesnt collect it. If you do the homework and understand it well, the tests are very fair. The are a bit difficult to finish in the allotted time, but overall he makes it easy to pass. Also, all of the exams are open note/open book/open internet so you have everything you could ever need to help you pass. Overall, loved this class with Mullisen, I wish he taught more often so I could have him for something else.

Mullisen is one of the best professors I have had at Poly. He is actually engaged in the material. Always starts class off with a joke. Brings turbine blades and other parts to class for us to see. Has plenty of real life stories that are worth hearing. Too bad he is retiring! Only downside, his midterm grading is a bit tough. But it\'s good for us.

This is one of those classes that's so easy that you stop coming to lecture and settle with a B in the class after a few mediocre midterms. Mullisen is an extremely nice guy with plenty of industry experience. His somewhat old-fashioned sense of humor makes you smile and proves a good distraction from T-s diagram upon T-s diagram upon T-s diagram upon T-s diagram upon T-s diagram upon... well, you get the idea. If you already know how to draw a T-s diagram, you might as well show up at week 9 where you finally start learning about psychrometrics, and then the game is all about psychrometric charts instead. This class is a breath of fresh air relative to the intensity of other 300-level ME courses, so savor it.

The previous comments are spot on. Mullisen is a Boss!!! He is perfect for Thermo 2; the easiest ME class I've taken so far yet I learned a lot and really enjoyed it. I wish he wasn't retired because he would be great for ME 341/347/343. Take him for Thermo 2!

Not a bad guy. He is difficult and stresses derivations and really prepares you for the difficulties encountered as an engineer. However his vast knowledge of heat transfer affected his lecturing ability. He seemed to not understand the students' difficulties with the subject and rarely worked example probelms in class. However he has a great ability to teach in office hours. His attitude towards studetns is welcomng.

Dr. Mullisen is one of the best teachers I've ever had here at Cal Poly. I always was eager to go to class because he conveyed the subject matter so well. He always had good examples and was able to relate examples to things we see in everyday life. He does make sure you know your stuff on the exams though. I felt like I had a good grasp on the material going into the test and everytime he stumped me on some problem. The problems on the exam were doable if you really understood the material inside and out.

Dr. Mullisen is the best instructor I have had here at Cal Poly. He loves heat transfer and thermodynamics and does an excellent job during lecture. His lectures are well organized, his notes are refined and clear with good examples. He is very helpful during office hours and is extremely friendly. The exams are fair and very do-able. Several times when I was taking heat transfer and thermal engineering more than one student would get 100's on the exams. Several times 3,4 sometimes 5 or 6 people would score 100. Overall, scores were high. He collects homework, but posts solutions to the homework BEFORE it is due, which allows you to check your work before you turn it in. That is very helpful, but be careful not to abuse this.

Mullisen is a great guy. He really loves Heat Transfer and he loves teaching. His lectures are very organized and easy to follow plus he makes sure that everyone is paying attention. If someone starts to daydream he'll stop the class and "invite" the daydreamers to rejoin the lecture. He really has a good sense of humor and would start off class with a joke about once a week. Tests were very fair. If you had done and understood the homework (not just copied it off the solutions he posts before it's due) you will not have a problem with them. The final was pretty challenging though, but again if you know your stuff it shouldn't be that hard. About the only thing I didn't about his class was that he didn't do enough concret examples during lecture. He spent most of the time writing down equations. Granted there are a TON of equations in Heat Transfer but I think that a few more examples would have helped me understand the concepts faster. He did kind of make up for this by dedicating the last 2 or 3 classes to nothing but example problems, but I would have preferred more throughout the course of the quarter. In spite of this small complaint I still highly recommend Mullisen for any thermo/heat transfer class he might be teaching.

Great teacher! He lectures very well and organize. He's friendly and helpful during his office hours. Before the test, Dr. Mullisen usually give review lecture notes, which are very helpful to study for the exam and final. Strongly recommend taking this professor!

I really liked Prof. Mullisen. He was always very prepared and organized and lectured at the pace of the class. He is a really friendly guy. Every Friday he tells a joke (which are not always that funny, but how many teachers tell a weekly joke?) Grading is fair. Total of 320 points in the class: the midterm worth 100, the final 200, and homework 20. That makes the final like 63% of the grade or something rediculous like that which is kind of intense--especially when seeing it wanted to make me cry. But he is a great teacher and the class is pretty interesting. Don't hesitate to take him if you get the chance.

He is one of the most energetic and enthusiastic professors I've had. He always has extrememly well planned lectures, but he lectures from memory not off a sheet. He also has many hands on examples of the topics he discusses. For example he brings in heat exchangers and other devices we discuss. He also has slides of real life applications for the topics in the class.

Mullisen is the shit. i thought i'd sleep through the 8am class, but mullisen ended up being alright. he always starts the class with the joke. really humorous overall, but he repeats jokes and stories sometimes. there was no hw. two midterms at 25% each and finals is 50%. i got a 100% on the first one, but failed the second one. ended up with a C+. It was a pretty easy class. He's tests are open book, open notes, and open neighbor. be smart about it and take advantage of that. you will do just fine.

Mullisen was a breath of fresh air from the typical slow and boring engineering professor. Was always enthusiastic about the material and willing to help students. Definitely one of the better professors in the ME department. There is no homework and your grade is 25% for each midterm and 50% for the final. I essentially failed both of his midterms, although looking back, they were stupid mistakes but he grades hard. He makes up for it with a curve at the end. I went into the final with about a 60% and got a C+ in the class. I felt the most confident about the final though, and must have done pretty well to pull out a C+. Fluids is a hard class, but Mullisen is a solid choice to take it with.

Best instructor Ive had at cal poly. If I could have him for every course, I would. No ME instructor surpasses him by a long shot. First Midterm easy; Second hard; Final hard; but puts a big curve on at the very end. Homework not due. Fantastic guy,loves fluid mechanics and heat transfer.

Dr. Mullisen is an awesome professor. I ended up with a D as I am a TERRIBLE test taker. You will learn a lot but his tests are TOUGH!. Less than 50 mins for 3 problems. Which means that you have about 15 mins a problem, assuming you can break it down and understand it quick and not make any time costly mistakes. I often times did not feel that I had enough time on the exams which made my grade suffer. The final was 7 problems, for 2 hours. I thought this was odd because aren't finals usually 3 hours? Your grade is the 2 midterms and a final. Time is not your friend in this class. Good professor though, just wish I had more time on the exams as most of my points were bled on small mistakes which I overlooked due to the time constraints.

Dr. Mullisen requires a group project, which may be time-consuming if you do not plan out the details of the experiment ahead of time. Research and start asking for advice as soon as the project is assigned. The final is worth 50% of your entire grade, and the questions are challenging. I was unable to get numeric answers for any of the questions on the final (or for the midterm), but with the partial credit he gave, I passed.

Mullisen is the man. There's really nothing else to say. I wish this guy was my grandpa, seriously. Nicest guy ever and has the coolest stories. He was a pilot and all around badass in Vietnam. Very smart man that conveys his thoughts very well. I enjoyed coming to his class and you will too if you take it! Doesn't collect homework, but you better do it! Two tests and a final during the quarter. See you in Thermo 2 Mull-man!

I only wish he had taught Thermodynamics when I took that last year. Mullisen is simply the best. His lectures are completely coherent because rather than copying his notes, he develops each individual lecture as he goes and uses his notes to keep himself from straying too far. As he says, he loves thermodynamics, he has a terrific attitude abotu everything, makes every effort to remember your name, to help you in class and out, with school related problems and with anything else that might be on your mind. Posting the solutions to HW allows you to make genuine efforts but not be punished for making small mistakes. Besides, the HW isn't worth much anyways in terms of grades. He spends the last 2 or 3 weeks covering applications of thermal engineering including the history of thermodynamics - all of which is very interesting (and possibly prone to show up on the final). We need more profs like him.

Dr. Mullisen is one of the best engineering professors available at Cal Poly. He makes lectures interesting and easy to follow, and always has things to show the class or funny stories to share. He's also very helpful in office hours with homework or lecture material. Dr. Mullisen truly wants his students to succeed and it shows in his teaching style.

As stated by everyone here, Professor Mullisen is one of the best in the ME department. He gives a superb lecture, riddled with plenty of intersting concepts and slides that describe the real-world applications of the sciences you are learning. He is very helpful in his office hours, and appreciates students that try their best to do the best they can, even if they don't do well on the tests. It seemed everyone did relatively well on the exams, and if you really KNOW how to do the homework, and *understand* it, you should do fine. However, if you are reading this while considering taking his class, let me tell you about what makes him hard. Because, although he is good, he is *hard*, not easy. I felt the workload, both assigned and expected, was unrealistic for a class of this sort. I spent more hours studying for his tests and doing his homework than I did for both of my other classes combined (one of which was Design II). The basis of his grading on tests is to see what you know. If you don't know it, he will fail you, and has no compunctions about giving you zero credit for using wrong equations or poor derivations. Don't try to baffle him with BS; it won't work. You could have ten pages of calculations, but if you began with the wrong equation (even if it was worked right), it shows him you don't understand the stuff, and he will give you *zilch* for it. Be aware of that. Understand the homework. Be warned also: you will be expected to do a term-project for Thermo. The project takes a lot of time and effort to complete, especially if you have poor group-mates. I couldn't care less about the subject of the project he assigned (he chooses a different one for you every quarter), and I don't have time to do it on top of my four other labs and projects I had this quarter (albeit I *made* the time for this one, nonetheless); my feeling was no one else did either. In the end, despite sacrificing several weekends and a whole lot of work, I was very disappointed with how he graded it. The final analysis: Be ready for a lot of work; and by that, I mean a *lot*. He's a good teacher, but know your stuff. Don't just copy homework solutions. Don't just study his notes. Do the problems, or you you'll be hurting by the end. Thank god this class is over. Good riddance.

I really don't get all the buzz about Mullisen. I had extremely high expectations since he was the department chair and I thought he would be as good if not better than Glen Thorncroft for thermo. But I was deceived. Deceived by the mighty Thermo Gods indeed. The course itself blows and could be wrapped up in a much shorter 2 units than its weighty 4. We kinda ran out of material at week 6 or 7. If you're not looking up h values in tables for cycles (over and over and over), your finding the freakin humidity ratios in the air. Lame as all hell. Mullisen also wasted countless hours of lectures with slides of material not pertaining to the tests. As much as I tried to find it interesting, it just felt like a waste of time that could have been done doing examples. Mullisen's tests are also very time crunched. We only got two hours for the final which bugged the crap out of me because I could have done much better with the full 3. We also got to do a kick ass project that involved finding Joule's constant using friction - probably the single worst project I've done at poly simply because I was looking for a published value and could not apply it to anything. Mullisen needs to stop drawing T-S diagrams in the sand and take a few lessons from the man who actually made me thought that I liked thermo- come back Glen....come back to 344 and quit teaching ME 236 for God sakes.
