    Hi Greg,

    when I looked at the homework help forum today before logging in, it invited me to "recieve" help on homework questions. Could someone correct that spelling, as it might compromise our rep as expert scholars, or maybe confirm our rep as science geeks ?

    In fact I am puzzled how such a misspelling could occur since when I tried to write this message, the spellchecker changed my misspelling twice to the correct one until I managed to preserve it.

    thanks,

    roy (mathwonk)

    Sorry I just singed up today and can't help you with the form. I also can't help you with your first question as I am a retired aerospace test engineer with a BS degree in physics.

    Hello Greg. I looked at this unanswered post on that Google Sheets list. It did not ask for an answer, and was just posting a proof. I suggest adding a column "Answer not needed" to the Google Sheets doc that we can mark if we find the post does not request or require an answer, to avoid multiple people looking at those posts.

    Hi Greg,
    I composed and sent an email via Physics Forums Comments to admin on July 3, 2021 asking about posting a few of my web pages containing solutions to undergraduate physics textbooks no longer used for associated courses. Please reply if you received the email.

    Thanks,

    Hi Greg, you ask me to support the site. After I upgraded to gold member one keep deleteing my post without reasonable reasons. Is this a internet cheatting site or some admin's account be hacked?
    Best wishes!

    Hi there, onexuan. Did you get a message (perhaps in your Inbox) telling you why certain posts of yours were deleted. There is always a reason, and it is usually because of content that is not appropriate for the board, though I can't be sure. You may want to review the site rules that you agreed to when you signed up.

    It really depends on the case. E.g. we offer tutorials and homework help by people who are or have been professors or teachers without extra costs. The only requirement is that the students show us where they failed, where they reached a dead end. This is necessary to provide high quality help, and it also makes sure that we are not abused by lazy students who want their homework to be done by somebody else.

    Why do you send me emails to come to the site if you will not give me permission to post? When people seem to know the answers and do not want to give them for homework reasons that is one thing but a question that even people who so plainly know what is going on do not understand how to answer a problem there's really no sense in my being here if I cannot comment. While approximately 1 Kw hits the ground why doesn't anyone plainly answer what becomes of it?

    Hello, what is noun of Energy which explained like E^2 = P^2.c^2 + m^2.c^4 ??? ( Joule, km/h etc.)

    You've posted this question on Greg's profile, which won't be read by many people and where replies are limited in length. Technical questions should be asked in the technical forums - in this case probably Classical Physics. Go there and click "Post thread".

    I'm not aware of the word "noun" used in the context you are using it. Do you mean "unit"? If so, you may find it faster and easier to google "unit of energy".

    So how do I show people that gravity attracts in straight lines? By first getting it published in a scientific journal? That sounds like a dog chasing its tail. I had the same problem with an assistant philosophy professor who dismissed my argument regarding Descartes' "pilot on a ship" reference, where I showed that the Head of philosophy was 180 degrees wrong in his study guide. Fortunately the Head agreed with me.

    actually how can any thing pull unless you grip that means gravitaional force is pulling is wrong so first of all we should see everything by common sene which is never given by books

    it is very important to note that it is one thing which is throwing every thing to earth .and in complete universal bodies

    we should name it as shiv tatva. all qualities of shiv tatva matches shiv . you may feel it religeous but it is scientific.
    it is not required to know any science to understand that since even lay man will agree me if explained properly
    Hi,

    when I create the thread "Bohmian mechanics for instrumentalists and quantum measurement" i get in return an error message : Ooops : we can run into some problems. however it seems that thread has been created several times. He's the last one the right one.

    Yes, I would actually like to write an insight article, but I'm working so much nowadays that I get very little time to do that. By the same reason, I have very little time to post in general here, despite that I was made Science Advisor. I'm really sorry for that.

    Hi Greg, could try to write an insight, for some time now I was thinking an insight about the fundamental theorem of calculus. But you got to tell me how exactly to write it, what latex editor or other tools should I install.

    Hi Greg, you may remember me as the pain in the ass who was searching out electromagnetism for the purpose of stopping large objects. For the life of me I cannot find that forum. Seems you would know how to do that. I was hoping to resurrect the forum with more questions and ideas.

    Aww shucks, I looked around and cannot find what a crossed out, a line strike through, across a user's name indicates. I think it means a peep that is no longer active for whatever reason?

    Hello, my teacher, do you know this prophecy?
    Theorem: A is an R module and B is a sub-module of A. There is a 1-1 mapping between the set of submodules that contain A and B and the submodule set of A / B.

    Can I get information about proof?
