Professor Young is an incredible lecturer and gives creative, challenging, and enjoyable homework problems that test your understanding of the subject and occasionally explore more advanced topics in the field (e.g. coherent states in quantum optics). His exams are notoriously hard; do lots of practice problems and be efficient come test day.

One of the best lecturers I've had so far. Very knowledgable and can answer any question thoroughly. Homeworks are hard and so are the tests, but he helps you learn the material very well. Quantum is always going to be difficult but he makes the ride enjoyable.

Good enough lecturer. Very good lecture notes, and tough exams. Attendance not required; I went to lecture a grand total of 4 times during the quarter, but was still able to keep up due to the good lecture notes.

Prof. Young is a great lecturer. He really knows how to get his points across. If you pay attention, read the textbook, and complete the homework you will do fine. He rarely fails students. His exams are as hard as everyone says (expect 40-50% averages), but the curves are very generous in the end.

He is so unpredictable. Course content is not well-organized. DOn't expect what you learnt will appear on the exam. What makes his exam diffcult is that you never see the concepts or learn them before. Try your best to avoid. You learn almost nothing, and get a terrible grade.

Professor Young is obviously passionate about the material he is teaching. His lectures are great, and the homework/discussion section problems (specifically the ones not from the textbook) are really enjoyable. On the other hand, his exams are tough. He does a generous curve at the end of quarter, and it seems that most people end up fine.

AVOID HIM!!! Homework is harder than any courses I've ever taken but much easier than his exams, and you only have two days to work on the homework since it's due Friday. The mean for the midterm (after regrade) is 55% and for the final is 60%. The lectures are absolutely UNORGANIZED, and he uses the old version textbook for Thermodynamics.

The midterm average is 47%, the final might be even lower. HWs were way too easy to prepare us well. Lectures were clear on introducing basic ideas, but often unorganized, thus confusing.

Don't get me wrong, Dr. Young is a genius and you will enjoy the lectures. They are interesting and very informational. But this class is extremely difficult, the pacing is very off and the workload is very heavy. But the main drawback from this class are the: not helpful at all and are extremely tough graders – will not give partial credit.

AVOID HIM AT ALL COSTS. Loads of homework, tons of quizzes, harshly graded. Exams are insane, midterm average is 47%, so low that even he can't stand it and gave an overall regrade. HW due Friday than Sunday and late by 10 mins gets 50% off punishment. Good news is PHYS 22 now can be taken in spring and with different profs. You CAN avoid him!

He often goes is to derivations way above the math prep required for the class. The understanding and manipulation of those derivations are then on tests. He is, also, hard to access during OH, often late. The homework, also, lulls you into a false since of security. Makes sure to COMPLETLY understand his notes and textbook.

Took this in Spring 2021. Exams are 10 times harder than HWs. Expect the average to be around 40%. He adds upper division materials into the lectures and exams. His notes contain errors and handwriting is terrible. He gets frustrated easily in his office hours so be patient. Go to TAs for questions are much more efficient. Avoid him at all costs.
