Physics Learning Challenges

Discussions focus on the depth, difficulty, and joys of studying physics, including personal experiences from engineers and CS backgrounds, debates on accessibility for non-physicists, and comparisons to formal education.

I think this is still fair.I mean when you study Physics you learn to use apparently confusing tools - theoretical or experimental - with confidence. Sometimes in areas that only few people find interesting/appealing, like for instance complex problems in classical mechanics or thermodynamics. Only 1% of the studies is about crazy, absolutely counter-intuitive stuff that sounds like Sci-Fi. But isn't that what differentiates the amateur from the Pro? ;)I mean if people want to do

Lovely.This is on my mind too.Am an engineer (EE + CS) with 25 years of work experience, with a passion for Physics. Am widely known in my circles as a scientist/physicist, however, I do not actually know much. Learned some Lagrangian and Hamiltonian classical physics recently.I personally do not mind going for even an undergrad in Physics if that would be a better fit for me to learn. :-)

Your “physics envy” alarm went off.https://en.wikipedia.org/wiki/Physics_envy

This reads to me like you’re assuming OP is looking to make a career in Physics—what if they’re just looking to learn more about what comprises the field, or to satiate their own curiosity?

Oh, that's really interesting... I didn't know that (I know very little about physics, I'm more of the mathematician kind).

One thing about the traditional sequence of physics topics, is that it progresses (more or less) in parallel with the traditional math sequence. So you can get yourself up to speed on both simultaneously.Also, you don't need to get all the way to the whiz-bang stuff, for it to be both enjoyable and useful. Granted, my degree was 30+ years ago, but today I specialize in designing measurement equipment. If all you end up learning is calculus plus how some mundane things work like circuits

Some students might do better to take physics instead of engineering. There is a broader perspective in physics and the origins of concepts and formulae are usually considered relevant topics for discussion.

this is a great site. it really makes a good case why no one should want to be a (good) physicist. reading this stuff takes decades i should think.

Unfortunately you would need a strong education in physics to learn that. I have a PhD in theoretical quantum physics and even then it would take me years to even slightly grasp string theory and the like

please explain your sentiment (speaking as a cs undergrad who failed physics once but is still interested learning)
