Course Description

PHYS 102.1x serves as an introduction to electricity and magnetism, following the standard second semester college physics sequence. Part 1 begins with electric charge in matter, the forces between charges, the electric field, Gauss’s Law, and the electric potential. Electric current and resistance are introduced, and then DC circuits are described, including time-dependent behavior with resistors and capacitors. PHYS 102.1x consists of 5 weekly learning sequences, each with ~1.5 hours of video lectures, conceptual lecture problems, and online homework questions. The course concludes with an online exam during the 6th week.  

What are the prerequisites?
We will assume that you are familiar with vectors, that you know how to calculate integrals, and that you have had introductory mechanics. These topics will be briefly reviewed as needed, but not in a systematic way. If you have not had classes in these topics it ma...

What are the prerequisites?
We will assume that you are familiar with vectors, that you know how to calculate integrals, and that you have had introductory mechanics. These topics will be briefly reviewed as needed, but not in a systematic way. If you have not had classes in these topics it may be possible to complete the course with extra study.

What textbook is required?
The course will not strictly follow or make assignments from a specific textbook.  Any recent freshman physics textbook will suffice. Reading assignments will be given by topic, including links to several free online physics textbooks.

Best physics course I have ever taken. Intuitive, yet rigorous coverage of all materials. Homework difficulty was just right and fills any gap in concepts. Thank you professor Hafner. Looking forward to continue learning in the second part of this course.

Excellent! Great introduction to the topic. Right level of challenge for learners who are serious but don't want to pull their hair out trying the problems.

In summary, the Professor's teaching method is generally effective because he communicates his own understanding of the subject matter clearly to the audience, via the blackboard. Overall, my learning interest was sustained continuously throughout Parts 1 and 2 of the online course and the Instructor's enthusiasm for Physics is clearly evident. Even though I am a Physics major who completed my university studies several years ago, I was able to learn some new content from this course.

Highlights: + Excellent lectures + Good problem sets + Enlightening demonstrations Lectures: Excellent lecturing by Prof. Jason Hafner. He presents the concepts clearly with good examples and anticipates confusions dispelling these before they cause real difficulties. His "signal-to-noise" ratio is high: he doesn't waste time with superfluous comments or unnecessary repetition. Another way to put this is that very little could be removed from his lecture without adversely affecting understanding. His board-work is clear and readable. Most unusually for an academic, his comic timing is spot-on. He does several demonstrations, especially in the early weeks, and these help make real the theory he discusses on the chalkboard. Prerequisites: You definitely need experience with the integral calculus, vectors, and surface integrals. None of the integrals are difficult, but you need to understand how to set them up.

Prerequisites: You definitely need experience with the integral calculus, vectors, and surface integrals. None of the integrals are difficult, but you need to understand how to set them up. Problem sets: There is one problem set per week of lecture plus a final exam. Overall these problems sets are quite good helping to cement the concepts discussed in the lecture. I like the ones that require math, but there should be more conceptual (non-calculation based) questions. Visualizations: There are a few visualizations to help in understanding how field lines are shaped. Lab Demonstrations: Several in weeks 1 and 2 help to solidify the concepts previously presented. None in week 3, but a few in later weeks when discussing DC circuits. A few areas for improvement: * There were no in-lecture questions. * Never mentioned "conservative fields". * Make available optional at-home labs. This would cost extra money, but would greatly aid in understanding. Summary: A high-quality course.

The best course I have taken so far. Fun and informative. I seriously hope Prof. Hafner keeps up the good work. Future courses in this fashion will be highly appreciated.

Prof. Hafner is an outstanding, exceptional & engaging teacher. His courses are the only MOOC's I have taken where I have felt as if I was in a real classroom - with the prof. I took E&M 1 & 2 - hope to review & improve with this self-paced version. MOOC deadlines are nerve-racking when other parts of life come on the scene that must take priority, so this self-pacing is a relief. The material (for me) was challenging - with just the right mix of theory, lecture, demos & homework difficulty. Enjoy!

This course was my first introduction to electromagnetism . It is an excellent course for teaching this topic to people without previous knowledge of EM who however have a sound mechanics and calculus background . Unlike other courses , the professor is great at teaching the essential mathematics along the way . The course can be taken by students with a sound single variable calculus background for this reason .

Jason Hafner is really a great instructor, master of interleaving the most complex math concepts with funny breaks. The content is well structured and very deep, helping students to learn both low and high level concepts. The experiments are fun and memorable. Hafner is successful in exploiting the peculiarities of MOOCs technologies to improve the effectiveness of the learning experience.

This course is amazing. The teacher is spectacular. I just wish the course could become self-paced, I ended up not finishing it due to other things taking most of my time back then which caused me to miss a few deadlines.
