Hello -- Questions about how to post on PF via mobile

[AlexJicu08]

How did you find PF?: Google search

I am a 14yo student from Romania. I participated twice in the National Physics Olympiad and I won a Science Olympiad.
I like writing physics problems, so this is the reason I am on this forum.

Welcome to PF and congratulations on your success in the Olympiads so far. Keep it up!

Welcome to PF and congratulations on your success in the Olympiads so far. Keep it up!

Thanks! Can you give me a rough explanation on how to post something? I am totally new and a can't figure it out.

Sure!

For general technical questions, post them in the appropriate technical forum (start the thread by filling out the form at the top of the forum) and include links to your reading that you've been doing and ask questions about that reading. In some of the technical forums the thread title will include a prefix that you can set to B/I/A for Beginner/Intermediate/Advanced for the level that you would like the replies to be. I is undergraduate university level, and A is graduate school level and above.

For schoolwork-related problems, post in the Homework Help forums and fill out the Template that you are provided there when starting a new schoolwork thread. That includes the Problem Statement, the Relevant Equations, and your Attempt at the Solution. Always show your work on the problem so that we can then provide tutorial help.

The Homework Statement is where you list the problem word-for-word as it is given to you. You can also upload a PDF or JPEG image of the problem if that helps, but it's usually required that you type the problem in as well. The Relevant Equations section is to help you think about and list the equations and formulas and concepts that may be helpful in working the problem. You then show your work in the section below (the main body of the thread start).

To post math equations, it's best to use the LaTeX engine that PF provides. There is a helpful "LaTeX Guide" link below the Edit window to get you started. Note that you put double-$ delimiters at the start and end of each stand-alone line of LaTeX, and double-# delimiters at the start and end of in-line LaTeX that does not need to be on its own line. Also, if you right-click on a LaTeX equation in a post, you get a pop-up menu to let you view the LaTeX source or view it in other formats.

LaTeX isn't supported in thread titles, so you can use simple text math in titles if you want.

Note also that PF uses a feature called "lazy LaTeX rendering" that speeds up page loads. When you first post your LaTeX in a thread, you will not see it rendered that first time. Just refresh your browser page to force it to be rendered, and then it should render whenever you come back to that page/thread in the future.

Let me know if you have more questions.

Thanks! However I still do have a question. I understand where I have to post every question, but where can I find the Homework Help forums for example on the mobile version of the website?

 

[berkeman]

I'm on my PC at the moment, but I can pull up PF on my phone and take a screenshot if that will help. When you are at the top level of the website physicsforums.com you should see something like this:

But I will check that on my phone now to see what it looks like there...

 

[berkeman]

Yeah, it looks even simpler on my Android phone (I'm not logged in ATM, but it should look the same after I log in via my phone):

 

[AlexJicu08]

I see, but on this page where can I start a new thread? I know I understand very hard and I thank you for your patience.

 

[berkeman]

No worries. When I log on and click on the Introductory Physics forum, I see this:

So I click in the box that says "Enter a Descriptive Title" and put in my thread title (I will just use Foo for now)

Then you see the sections where you can put in the Homework Statement (problem statement) and the Relevant Equations, and then you can scroll down to the section where you show your work toward the solution. After that is all filled out, just Post the new thread.

See if that works for you!

Thank you very much for your help and for your patience again!

 

[berkeman]

You are very welcome.

Since this Introduction thread now has some useful info in it for how to post your first thread(s) here at PF, I will add to the thread title and move it to the Feedback forum where it can help other folks if they have similar posting questions.

Feel free to post follow-up questions in this thread, or you can always send a Private Message (PM) to me or other Mentors by clicking on our Avatar and "Start a conversation". Enjoy PF!

Or you can click on the "Post Thread" button at the top, which will show you all the boxes for the sections of a new post. You'll have to scroll down to see all of them. Clicking "Post Thread" at the end of that page will actually post the message.
