Discussion Overview

The discussion centers around the feasibility of taking upper division Electromagnetic Theory (E&M) given the participant's academic background and current course load. It explores the prerequisites, personal experiences, and expectations related to the course's difficulty, particularly in relation to mathematical skills and time commitment.

Discussion Character

  • Exploratory
  • Debate/contested
  • Mathematical reasoning

Main Points Raised

  • One participant expresses concern about their preparedness for upper division E&M, noting they have not taken classical mechanics or lower division modern physics but have completed the necessary math prerequisites.
  • Another participant suggests that as long as the individual is comfortable with vector calculus, they should be fine in the course.
  • A participant shares their own experience, stating that they successfully completed E&M with a similar background and emphasizes that while the math required is manageable, the homework can be very time-consuming.
  • There is a repeated emphasis on the complexity and length of homework assignments, with estimates of time required varying significantly based on individual mathematical competence.
  • One participant humorously notes that their experience with abstract algebra has prepared them for tackling challenging problems in E&M.

Areas of Agreement / Disagreement

Participants generally agree that upper division E&M is doable for someone with the right mathematical background, but there is no consensus on the exact level of difficulty or time commitment required for homework assignments.

Contextual Notes

Participants reference varying levels of preparedness and personal experiences, indicating that individual performance may depend on specific skills and prior knowledge.

So I kinda got painted into a corner this upcoming quarter. I am trying to do a Math/Physics double major and with all the req's for both majors, I pretty much got no time to be taking easy quarters (unless I want to waste time going to school an extra year. I am 31 y/o, I still want to do grad school, so no...there is no more 'taking my time').

With a few scheduling conflicts, I couldn't find/fit an extra math class for winter, so I decided to enroll in the first quarter of upper division E and M.

Heres the thing: I took lower division E and M over the summer, I have not taken the first quarter of upper division classical mechanics, nor have I taken the first quarter of lower division modern physics (quantum and special relativity). Is upper div E and M doable for me? The pre-reqs only require Multi-Var calc, Math Methods for Physics and lower div E and M of which I've done all three.

My schedule would look like this:
Upper Div Linear Algebra II
Abstract Algebra I
Lower Div Modern Physics I
Lower Div Experimental Physics Lab II (basically a experimental techniques lab)
and of course Upper Div Electromagnetic Theory I

Does this sound like a doable scenerio? I should mention that I am retaking Abstract Algebra (had to drop it due to severe illness this past quarter).

As long as you're comfortable with vector calculus you'll be fine. It's all reasonably straightforward as long as you are buddy-buddy with div, grad, and curl.

Yeah, I am solid with it now. I took Multi-Var calc last fall, then took Math Methods (with Boas' text) over the summer which was pretty much a crash course on the first two years of Uni math, which included vector calc, so I'm pretty much up to date on that stuff.
 
E&M is totally doable with your background. I took it as an EE major and I also only had the first semester of modern physics and no classical mechanics or any other upper-division physics classes. I got an A in the class and actually did better than some of the physics majors! I will warn you though, that while the problems don't require any math higher than vector calc and linear algebra/diff eq, they are often extremely long, complex, and time-consuming. Expect to take at least 10 hours to finish a homework assignment with 4-5 problems (if you're very good at vector calc and generally mathematically competent) or as many as 30-40 hours per assignment (if you struggle).

Hahaha...after having plowed through some of these abstract algebra problems, I am no longer fazed by marathon problems.
