Meta Homework Help Etiquette (HHE)

156 Upvotes

Greetings budding physicists!

One of the things that makes this subreddit helpful to students is the communities ability to band together and help users with physics questions and homework they may be stuck on. In light of this, I have implemented an overhaul to the HW Help post guidelines that I like to call Homework Help Etiquette (HHE). See below for:

  • HHE for Helpees
  • HHE for Helpers

HHE for Helpees

  1. Format your titles as follows: [Course HW is From] Question about HW.
  2. Post clear pictures of the problem in question.
  3. Talk us through your 1st attempt so we know what you've tried, either in the post title or as a comment.
  4. Don't use users here to cheat on quizzes, tests, etc.

Good Example

HHE for Helpers

  1. If there are no signs of a 1st attempt, refrain from replying. This is to avoid lazy HW Help posts.
  2. Don't give out answers. That will hurt them in the long run. Gently guide them onto the right path.
  3. Report posts that seem sketchy or don't follow etiquette to Rule 1, or simply mention HHE.

Thank you all! Happy physics-ing.

Need Advice advice for career change to physics

2 Upvotes

basically, my boyfriend (24y.o) is studying general medicine now, but physics and math has always been his passion, especially theoretical physics, he for sure regrets following the medical path but he doesn't think of having career change since these are all years taken from his life and i do respect that.

but just in case he wish to change that one day i want to be there to support him, so i just want to know if it's possible, how long would it take him? is it worth it? how can i support his passion better?

in a way i don't want him to be stuck doing something he doesn't like for the rest of his life.. but it's his decision

Update 3 months ago, I made a post here saying I felt scared and disconnected from quantum mechanics. Today I got my results back, and I couldn’t be more proud of myself.

46 Upvotes

3 months ago, I made a post here talking about how much quantum mechanics scared me. I went to every lecture questioning how I was ever supposed to learn this. I literally felt like I was walking into a class that I was in no way prepared for.

Today my results were released. 92/100, my best mark in a course ever. I am so unbelievably proud of myself. I worked so incredibly hard, and I’m so happy that my hard work has been reflected in my mark.

The cherry on top is that i landed a research project with my professor from that class, working on finding the energy bands in artificial crystals. Can’t wait to start that and try some actual theoretical physics research.

Thank you to everyone who commented on my last post to give advice, it was clearly good advice.

HW Help [Quantum Field Theory]: Showing conserved current

Post image
23 Upvotes

For the above Lagrangian density, I'm asked to check whether the current J^μ is conserved. Putting all this in the Euler Lagrange equation and taking the four-derivative yields \partial_μ J^μ = -m²\partial_μ Α^μ. So this current is not conserved. I'm then asked to find a condition for it to be conserved. Would I just have to pick a gauge such that partial_μ Α^μ=0? Or would I have to apply Noether's theorem to find an expression for J^μ?

Rant/Vent Can I ask questions about basic physics one stuff in here

4 Upvotes

I’m a junior in hs and I’ve only taken algebra 1 up to this point—in alg 2 now so this is taking me out. Im honestly considering just dropping out because so far this has been borderline impossible without the prerequisites of at LEAST algebra two, but preferably pre calc which I’m not even touching yet.

Need Advice There’s a gap between knowing Physics and seeing Physics. How do you cross it?

7 Upvotes

I'm a high-school student preparing for a competitive Physics exam, and I've noticed a problem in my Physics learning that I don't really know how to fix.

I can learn the theory and understand what the equations are saying at a basic level. I can memorize/use formulas and sometimes follow a derivation. But in my mind, many Physics concepts still feel like mathematical symbols rather than something physical that I can actually picture or reason about.

For example, I might know an equation and understand its theoretical meaning, but when I encounter a complex or unfamiliar problem, I often can't immediately translate the information into a physical picture:

  • What is actually happening physically?
  • What should I visualize?
  • Which quantities should I connect?
  • What should I try first?
  • Which principles might be relevant?

As a result, when I see a difficult problem, my mind can almost go blank even though I technically know the concepts involved. I can sometimes understand the solution once someone explains it, but generating the approach myself is much harder.

I'm trying to understand whether this is mainly a lack of physical intuition/visualization, a lack of problem-solving experience, or both.

For people who are good at solving unfamiliar Physics problems—especially Physics Olympiad students, university students, teachers, or physicists:

1. How did you develop the ability to mentally visualize what equations and concepts actually represent physically?

2. When you encounter a completely unfamiliar problem, what do you consciously do in the first few minutes?

3. How do you turn a problem statement into a physical model before writing equations?

4. Can physical intuition and visualization be deliberately trained, or does it mainly develop after solving a very large number of problems?

5. What kind of practice would you recommend for someone whose main weakness is going from "I know the theory" → "I can actually reason with it in an unfamiliar situation"?

I'm not really looking for advice like "practice more" or "understand the concepts." I'm trying to understand what the actual mental process of an experienced problem solver looks like, and how a beginner can deliberately train that process.

Need Advice Struggling in PHY101, trying to find the best workbook for my course!

1 Upvotes

I’ve been struggling in my new physics class, it’s PHY101 at a cc and it’s the first physics class I’ve ever taken. It’s not calc based, but more of an intro/application course with the major units motion, forces&momentum, work energy storage and transfer, properties of matter, and atomic&nuclear processes.

Does anyone know of any good workbooks that explain the topics and include practice problems??
I’ve heard good things about a few, including:

Physics with answers:500 problems and solutions

No-frills physics

And many more, could someone please recommend me some or give some thoughts!!

From my perspective it's an energy vortex simulation and I am not a coder nor a researcher although physics is everywhere.

Rant/Vent Gave up looking for relevant work and now it’s been seven years

14 Upvotes

Graduated in 2019, bachelors in physics with a concentration in astronomy. I was working in the restaurant industry and covid happened and a bunch of other life events that led to me getting stuck with that for a while. I’ve looked at data analysis jobs quite a bit, but the only thing on my resume is restaurants and physics. I have experience from my research projects and I’m a published co-author for one paper in the minor planet bulletin, haha that’s probably the coolest thing on the resume. No one has been interested this entire time. I wanted to be an engineer originally but gave up on that when I realized that physics just isn’t appealing for most of those positions (they all want engineering majors). So I’ve just continued on working totally unrelated odd jobs until recently I said screw it and got into a good manufacturing company as a machine operator through a temp agency. They had no idea I even have an education, but this past week they decided they want to hire me on permanently just based off my work ethic! So now I’m trying to figure out how to convey that I have a bachelors and want to move up in the company without sounding like an entitled college grad (because all the rejection in the past kind of made me feel like that’s how my resume makes me look). Anyone else done anything similar to this?

Need Advice Need materials for my major pls

1 Upvotes

I came into my school as a BME major, but quickly fell inlove with physics. So now i'm doing a B.S in physics and astronomy + a minor in aerospace engineering and would love some youtube video essays, podcasts, audiobooks that can help me get through my physics and calculus series because khan academy can only do some much...

For reference on how I already prepare for class: i take notes on the textbook before class, add details during lecture, and then make quizzes/quizlets based off of my notes, but it would be amazing to have some videos or something to immerse myself in content outside of my notes. Thxs!

Need Advice should i change majors or quit university

5 Upvotes

i hope this post doesn’t violate any rules, i did read them but idk if i understood properly.

idk how to start this post… i just need genuine help.
lets just start by saying i have MDD (major depressive disorder) and GAD (generalized anxiety disorder).
i’m medicated but going through withdrawal at the moment so please excuse any errors, i can’t concentrate properly.

it’s only been TWO weeks since uni started, my major is physics and astronomy, and i already feel behind even tho i studied everyday ever since we started, EVERYDAY.
we’re currently studying the “serway physics for scientists and engineers”, we’ve been taking some BASIC shit and i already feel lost and stupid..

for context:
polar coordinates
vectors
electric field

we’ve already taken these things at highschool but at a simpler level, i NEVER had any issues at highschool with physics whatsoever, not at polar cords nor vectors nor electric field.

i genuinely don’t know what to do, my brain is such a mess…. i probably should change my major or something idk..

again i apologize if this post doesn’t have enough info, if you have any questions please ask i need opinions.

Need Advice I am looking for a research mentor.

0 Upvotes

I finished almost all fundamental physics, not mastering perfectly from memory, but I can perform with no error when there are resources to assist me —Which is research. But I am still a beginner, and I feel lost and I want to publish my first paper soon. If there is someone willing to tutor me, DM me. You can also check if I really master these things because it's desperate when you know my age.

My field is general relativity and quantum mechanics.

I will "Do my own work", I do not request someone to write the paper, I just want mentorship.

Need Advice Need advice to Study in MIPT, Russia

0 Upvotes

Hello everyone, I'm currently a student from Bangladesh and I want to complete my undergraduation in Theoretical physics from MIPT. I did some of my own research about it online and came to know that MIPT is one of the best universities to study physics with it's unique curriculum and lab facilities.

I'll be applying for a full scholarship.

Now, I just want to know about the overall expenses and environment in Moscow, and Russian culture and language. Is it quite hard to cope up? What difficulties will I have to face after reaching Russia? How international students are treated in Russia?

Also because of the geopolitical aspect, has it caused any negative effects in research fundings and overall study environment? And lastly, is it really worth it to study in MIPT.

Off Topic I wrote some notes on linear algebra and its applications in differential equations

2 Upvotes

Hey guys, I was reviewing some linear algebra and a tiny bit of differential equations before I got started on chapter 3 of Griffiths electrodynamics (which deals with solving Laplace's equations using separation of variables) and I figured that I might as well share my notes with you all. Linear algebra gets a bad rep as a "shut up and calculate" course so I wanted to try and do it justice by making explicit the connection between it and differential equations.

I hope my notes helps someone out! Here is a link to my personal Google drive where you can download the PDF.

Need Advice How do I self study Quantum/Modern Physics?

1 Upvotes

Hello everybody! I've recently started a course on quantum physics, but I'm quickly coming to realize that the professor really isn't all that much of a help. I find the content very conceptually interesting but I'm working on the first assignment (which is on interference, double slit, michelson/morely, etc) and I'm realizing how little I actually understood.

What are some good resources (like videos, textbooks, etc) that I should look in so this is less terrible?

Need Advice Just a comfused student looking for guidance 😭

0 Upvotes

I am a NEET dropper who opted for BIOLOGY because of the fear of MATHEMATICS ( frightened even more than death 😭). Now I am not able to study for this exam ( totally depressed 😭) because I don't like mugging up this book "n" number of times . I want to pursue bsc physics ( because I love physics). I cannot go for Btech because I don't have maths and am confused because as a neet aspirant I never gave a thought to Plan -B ( thought I'll easily crack this exam, silly me 😭 )

Now, if I go for Bsc as a major in physics and minor in mathematics and computer science. I just want your genuine suggestions about my career paths which I am assuming right now:

I am thinking in a way like if my math gets better with time

- I'll go for quant finance

- If I want to pursue engineering further I'll go for Mtech quantum computing

- If none of this works, I'll go for pure sciences - masters in astrophysics

I don't know much please put light on the above directions, because I don't want to take multiple drops anymore I am exhausted and want to pursue my interest and most importantly I want to secure a job after all these efforts...
