I posted a reply to this one:
https://www.physicsforums.com/threads/air-pressure-with-bernoullis-equation.144674/post-6652812
The OP is asking about specific problems in a cited textbook; I punted to "other Bernoulli threads." I hope that is OK.

We also have an Insights article on Demystifying Bernoulli's equation.

[Greg Bernhardt]

That's what I had in mind.

Yeah linking to a relevant Insight is a good idea and easy!

@Greg Bernhardt
Just curious. How many unanswered threads are there now?

Thanks @Astronuc

I posted replies to two more threads. It's slim pickings, though $~\dots$

That's a good thing.

And I checked two posts that had been answered by someone else

Thanks @Astronuc !
I added this to the 'old' thread.

 

[Greg Bernhardt]

Superb effort everyone! Down to 88 outside of Matlab.

 

[Office_Shredder]

I did my first one today, hurray.

I would be happy to try to do some of the Matlab ones, but I haven't done it in a while and I don't have access to Matlab so can't play around to remember how it all fits together.

 

[malawi_glenn]

I did one too :-)

 

[scottdave]

I looked at the links on your spreadsheet. I am willing to help.

Edit - I've done 2 so far

 

[scottdave]

Hi @Greg Bernhardt

Something is awry with the links in your spreadsheet. I did some, earlier today. Now when I click one, it goes to a completely different question.

For example: row 51 Jet Fire Calculations. The link in the spreadsheet is: https://www.physicsforums.com/threads/.440899 but this points to something completely different.

I was able to do a search and find this -
https://www.physicsforums.com/threads/jet-fire-calculations.282233/
I was hoping maybe the rows got shifted or something, but I cannot find 282233 in your spreadsheet.

Someone did what I did awhile back and sorted the table on column E. I restored a version from earlier today where the links still matched up with the subjects.

MathHelpBoards.com (MHB) has merged with PF!

.. and brought a load more unanswered threads with it. Quite a different style to the answers on MHB too (explicit answers to homework-style quesitons, some of which have ended up in non-homework topics).

It's messy for sure, but we'll get it figured out

 

[pbuk]

7 down, n - 7 to go but I'm done for a while. Looks like we've picked up some "characters" as well as posts, which is to be expected I suppose.

 

[pbuk]

I did another one. It would help if you could do a global RegExp replace on $\LaTeX$ tags on the imported posts - or perhaps you are already doing this, we just need to wait for it to work through them all.

Maybe you can help with this issue. I can't get single quotes and other tags types MHB was using to render. We are using this config for mathjax config. I have reached out to mathjax dev but nothing yet.

Do I have to report you for not using the [code=javascript] tag?

 

[fresh_42]

Do I have to report you for not using the [code=javascript] tag?

Solved. We are generous to first-time delinquents.

 

[pbuk]

Ah OK, that's the other way to do it (with the potential problems around "It was $100 but I got $10 off" etc.), although personally I would have gone for a one-off rewrite rather than a permanent run-time hack.

But I'm not getting that file, even with a cache flush. I'm getting

  tex: {
    inlineMath: [
      ["[itex]","[/itex]"],
      ["##","##"],
    ],
    displayMath: [
      ["[tex]","[/tex]"],
      ["$$","$$"],
      ['$','$'],
      ["[math]","[/math]"],
    ],
  },

... and I can confirm that it is working on the imported posts as expected according to that configuration, guess you may have to cache invalidate the new file for it to reach me at a UK endpoint.

 

[Greg Bernhardt]

Ah ok, so many cache platforms here. I purged Cloudflare, but it must still be in Litespeed cache. Let me see if I can flush that. But even still, it should render the single quotes as newline math.

 

[pbuk]

Do I understand correctly that there was a "Challenge" topic in MHB? Perhaps unsurprisingly this may have generated a lot of poor quality content similar to this fictitious example:

Prove the Peano axioms using only the Reimann Hypothesis and the Goldbach Conjecture.

There seem to be quite a few unanswered posts like this, can we deal with them en masse somehow? Or perhaps it is a matter of a few individuals e.g. @topsquark and @solakis1?

 

[Greg Bernhardt]

Correct, they had a challenges and puzzle forum. It may also just be that they had a lot of unanswered threads. This is a good opportunity to draw them into PF.

 

[Greg Bernhardt]

The file finally has been updated and I'm seeing some improvement.

Still having an issue rendering the backslash parenthesis

Still having an issue rendering the backslash parenthesis

I noticed the front end editor replaces \ with <span>\</span> so you can't enter a new \( or \[, but I can see no reason why it shouldn't work with an existing one.

 

[cjl]

Couldn't get the checkboxes working, but I added a response here. Seemed like a topic that could still be good general interest even if OP is long gone (which they likely are, given the age of the thread).

 

[Greg Bernhardt]

102 left! Awesome work! I'm going to throw this to the general public now and see if we can get a few more done! Thanks!

Incredible work everyone, down to 89!

Don't worry, next week I'll be refreshing the sheet with high-value MHB threads we need a reply for.

 

[Greg Bernhardt]

Ok, I added a tab for MHB threads without a reply that have high view counts. Let's see if we can whittle these down like the previous tab.

This thread:
https://www.physicsforums.com/threads/full-beamer-presentation-coded-in-latex.1038438/
I don't think it serves any useful purpose. I mean, somebody is giving their source code for a beamer presentation without anything else. Maybe delete it?

Edit:
And this one too: https://www.physicsforums.com/threads/latex-code-for-some-particular-differential-inequalities-and-their-proofs.1038434/

Some of these threads appear to be someone doing a student's homework for them. They don't really need a reply.

I am doing that, with a prefix "[Old MHB threads]" so that the mentors are not confused.

It looks like anything posted under the username Prove It could go. Alternatively, we could just edit the threads to keep the answer, so students could check their answers but still have to work it out themselves.

Definitely keep them, but you probably can lock them. They don't need a reply. Any visitor can start a new thread and reference to the old thread for any further questions.

 

[fresh_42]

Yes, it seems a bit pointless if "correct" is essentially all you can add. This is also sometimes the case in our usual homework threads. In all such cases, I try to add some additional information: wiki pages to read, the theory it belongs to, or some historical remarks. More because I feel stupid just saying "correct" than because of the OP.
