Greg-

This is an excellent piece on the CHSH inequality violations. Bell's analysis, in conjunction with the Clauser-Aspect experiments, make it clear that local realism is untenable, and that Nature must effect some kind of superluminal global coordination. Gell-Mann was famously unsurprised (It only proves what we've known all along - that quantum mechanics is correct. Big deal.) But I think that Gell-Mann was dead wrong not to be surprised. What is your position?

Let's Talk Big Bang and the Start of Our Universe! (Help Needed: My English is Basic, So Let's Make This Fun!)"Hello everyone! I'm from Mongolia and super excited to chat with anyone who loves learning about the Big Bang and how our universe began. But honestly, my English is not perfect – it's a little bit broken sometimes. So, please be patient if I make mistakes, and let's help each other out!

Hi Greg,

I've been checking those threads nearly every day for years.

Do you think I should check more often?

Hi @Greg Bernhardt

I think there is a typo in the Newcomer announcement. The other polls say they close on Jan 6th, but this one states Jan 3.

Here's the link - https://www.physicsforums.com/threads/new-member-award.1058488/

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!

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?

Hi Greg, according to the green banner, we can receive a Gold Membership by sharing PF on our Facebook's. Once it has been shared, who should we speak with about obtaining the Gold membership?

Thank you,

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.

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.

Thank

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.

Just a thought on the new Finance threads, you might want to rule out making recommendation of individual stocks.
