Prof. Weiss meets every standard for a good professor, except that his lack of organization and dabbling into sophisticated and irrelevant subjects most of the class did not understand made his class a pain in the butt for any non-bio/chem majors.

Don't make the same mistake I did. Take that other professor.

Professor Weiss cares more about student mastery of the material than any other professor I've had. Would definitely recommend to anyone who wants to truly master this courses's curriculum as well as material that was removed from the course.

Professor Weiss has entirely changed 20B from the normal syllabus of the class, he assigns homework and reading from the textbook but after the first month I completely stopped doing the reading because it has NOTHING to do with what you will talk about in lecture or what you will be tested over. His teaching and testing style are the weirdest and worst I have ever encountered, you can definitely tell that he is a researcher and not a professor (he doesn't let you forget it either because he brings up all his published papers and awards and friends who are nobel laureates every five seconds). He's a nice guy, but definitely not used to teaching this large of a class at this level and it shows, I don't think he prepared me very well for 30A and I did not enjoy his class, if you can take someone else, I would highly recommend doing so.

This class was supposed to be titled "Chemical Energetics and Change"
But what actually taught by Weiss were:
x-ray photoemission spectroscopy, x-ray diffraction crystallography, flow cytometry, fluorescent in-situ hybridization, silicone polymers, biopolymers, direct and indirect-band gap semiconductors, semimetals, semi-insulating semiconductors, and so on.

And yes, as you expected, these topics are designed not just for fun - they DiD appear on the exams, which were purely conceptual (no calculators were allowed, by the way, because there were NO questions involving any quantitative calculations). While the topics that were supposed to be in the syllabus - entropy, enthalpy calculations, acid-bases, kinetics, etc. were barely covered during lectures, which appeared to as highly incoherent, disorganized and strangely paced ("flow of consciousness" should be a better term) as a typical episode from Rick and Morty - that is, you never know what's coming up next.

I would recommend Weiss to all kids who are chemo-nerds/maniacs and enjoy bragging hours after hours about nanotechnology. However, if you intend to take chem20B to gain some true, fundamental and organized knowledge of chemistry, Weiss would never be your first choice.

We can see some pretty words coming from the latest review, praising Prof.Weiss for the "challenge and tests that conceptually prod your understanding of chemistry to previously unattained depths". Indeed, the materials covered during lectures are interesting and unprecedented. However, I would like to ask the reviewer:

"Did the extra course materials compensate for the loss in materials that were supposed to be taught but not covered in lectures?"

No they didn't. Weiss didn't really discussed much about thermodynamics, acid-bases, or equilibria. As a result, you have to study them on your own by referring to the textbook, which is indeed poorly written.

As an introductory course, chem 20b is designed to prepare undergraduates for their even tougher upper division chem/engineering courses. Thanks to Weiss, I can say that over 60% of the class became underprepared.

I do not want him to overthrow this course's original aim.

This class is almost entirely about Weiss' nanotechnology research and techniques more than about what supposed to be Chem20B materials. It got three midterms - lowest one dropped, and a final. You will be tested on those research as well, along with some weird grading criteria - it is like grading an essay. There is no calculation on the tests, it is conceptual and confusing - almost like a guessing game. The way he teaches lectures is like research talks, however the students, with very little background knowledge, have to "imagine" of what he is talking about. There are some days lectures will be on Skype, which is not helpful at all. I studied countless hours and still messed up in this class. Paul Weiss is a great researcher and a nice guy, but I definitely do not recommend this professor for Chem20B. Find another professor who will make you love and enjoy Chemistry.

I loved this class. My friend and I referred to it as "Storytime" because every one of his lectures was just him talking about funny stories and things about chemistry he thinks are interesting. That made the class super interesting and easy to make yourself go to. He's a funny little dude and what he teaches, he teaches well. However, he teaches pretty much none of the course curriculum, leaving that to the homework problems. So if you want to actually learn 20B, don't take him. But if you want to enjoy the class, Weiss is your man. You hardly need to take notes if you pay attention to the lectures and go to review sessions before tests. The tests aren't hard at all if you do that, plus there is a ton of extra credit available. It's annoying that he gives a ton of homework and it's due every lecture, especially since it's always on topics totally separate from the lectures. But all the test material comes from the lectures, not the homework, so it's not a huge deal. Overall, there's more work than there should be and you won't learn anything that you're supposed to, but it's super easy and even more interesting. I would recommend this to anyone who needs to take 20B but isn't any form of Chemist.

This class is very frustrating. Dr. Weiss was so busy and had no time to prepare the lectures. As a result, the lectures deviated so far away from the course description. It's a total waste of time to go to the lectures.

You can never tell how you're going to do on the tests. The TAs have very vague reasons for not giving you points because I'm assuming Paul Weiss just gives them a few keywords to go off of. This class was a great learning experience and was inspiring and optimism inducing, but overall it's incredibly frustrating.
