So my advisor is out of the country and I have to pick classes tomorrow, so I'm asking you guy's opinion. I'm a first year grad student and I've got 3 classes on my mind. I'm definitely taking graduate QM, but I'm trying to decide between stat mech and "grad level" electronics. I'm going to have to take stat mech sooner or later. I guess the pros to taking stat mech right now would be I would be able to study with my friends and get these course requirements out of the way ASAP. As for electronics, I'm interested in it because I work in a highly experimental lab and I'm sure I'll pick up some things that will be useful, but I'm not sure if it's worth it to take a whole class just so I might be able to hypothetically design and build a circuit in one week instead of two. I'm a novice with electronics, but I think this class would be a step to becoming a "guru." Right now my electronics skill is basically looking at a diagram and going "uh, that's a filter, that's an amplifier, that's an integrator" and thinking thinks like "a transistor is basically a faucet!" I talked to a few of my labmates. Some have taken it, some haven't. The ones who have taken it said it's useful sometimes because they find they want to do something they learned in the class, and if they hadn't taken it, they would have just needed to break out Horowitz & Hill and read and then maybe ask for some advice before they could attempt it. Does it sound like it might be worth putting of the Stat Mech for a year to take this electronics? The electronics cannot contribute to my coursework towards my degree by the way. All also admit the reason I'm interested in the electronics is because I like making things... I guess the essential thing I'm weighing is, is it worthwhile to make a temporary sacrifice to get broad knowledge, or is this one of those things where it's best to just cherry-pick what I need.
