Best lecturer I had all year. Great personality, thorough notes, and slow enough speed. Besides the first exam, the rest were incredibly easy (I just studied the homework and that's what worked for me). I heard other say they didn't care for him too much, but I personally really enjoyed him.

Very good at explaining concepts, not too good at explaining the math (which is the main focus of exams). Also pretty fun and artistic in lecture, but there is a lot he explains in lecture that can be confusing at times. Definitely wish he focused more on giving math examples in lecture than us having to figure it out all on our own.

Professor Nash is really good at explaining concepts. He chooses to spend lecture time discussing concepts instead of focusing a lot on math. He does a few examples, but the textbook has a lot of example problems. You can usually just look at a few problems in the textbook and do the homework. There are also a lot of office hours if you need help.

Nash's lectures consist of him explaining all of these formulas and concepts yet never showing you examples on how to use them. Therefore, when you get to the homework you are staring at your notes with a bunch of random useless information. This leads you to having to go to TA help session or online to see how to actually use the formulas.

I believe Nash does a great job teaching the course. Other people may disagree. You need to read for the course and not solely rely on the lectures if you want to do good.

Dr. Nash had a difficult time pacing his lectures and would skip example problems to conserve time, telling students, "You can do that later on your own time." I also did not appreciate that he used similar wording and the same images from the textbook. The point of lectures is to teach what the textbook doesn't cover well.

Nash always talks in a monotone voice. If you, for some reason, need to go to a morning lecture and he is the lecturer, you will constantly feel the need to fall asleep in class. Otherwise though, the information he says is useful and he does practice problems in class to demonstrate the calculations that he talks about.
