I agree, it’s a great idea.

Currently physics is covered in:

**Other Topics**(pre university)

Algebra-based Physics, Chemistry, Biology**Other Advanced Topics**

Miscellaneous, Interdisciplinary

The people asking questions in

If I'm not mistaken we mostly have advanced physics questions there.

Are we saying we want to re-structure our forums so that it's easier for folks to post in the right place? Having a Physics forum (and moving the relevant threads into it) might clarify, I agree.

Looks good! The only suggestion I can make is to give Chemistry its own sub-forum.

Okay. I've updated my previous post, and I've added some categories to make it more explicit.Looks good! The only suggestion I can make is to give Chemistry its own sub-forum.

Yet, there is a remark I would like to make. At some point in history I proposed a new subforum somewhere else, not on MHB. One of the more reasonable criticisms I received, said that subforums (new or old) should have enough traffic: Without it, they don't seem attractive to post in and their existence is marginal.

When I look into some of the currently existing subforums on MHB that would already be good candidates for physics related posts, I notice that the traffic is unfortunately not too high. Take "Advanced Applied Mathematics", for instance. There were only seven threads started in 2017 so far.

So, while I could certainly support the case for a separate "physics forum" (after all, why not, where there is also a "business mathematics" forum?) I suppose I would just like to caution against "over-binning" with too few "marbles per bin". One approach would be a "natural sciences and engineering" forum: At least from a somewhat conservative point of view, this overly broad family of fields has a lot of mathematical methodology in common.

So maybe it makes more sense to merge those sub forums, and perhaps add Physics more explicitly to it.

Alternatively, we might make Advanced Applied Mathematics and Physics sub forums under Other Advanced Topics, so that we don't mix what is still quite a respectable number of pages with threads.

Other Topics (pre-university) does seem to have had a fair amount of traffic, making it reasonable to split Physics off.

And we might split off Chemistry as well.

I'm also not so sure that Mathematical Physics tag goes in the physics forum. I guess that's a tricky one though.

If we go for this approach, the threads in Other Topics will have to be moved to the new sub forums.

Do you think one of the limitations are the need to categorize all the topics as Pre-University and University level math? With these categories, one needs to determine the 'difficulty' level of the math, instead of the just the topic itself.New proposal:

That is, we split offPhysicsandChemistryin Pre-University.

And we leave University Math as is, except that we explicitly addAdvanced Physicsto theOther Advanced Topics, while leavingMathematical PhysicsinAdvanced Applied Mathematics(at least for now).

WithAdvanced Physics, I'm aiming for Classical Mechanics, Optics, Electromagnetism, Thermodynamics, Fluid Mechanics, and the Standard Model, since generally the math for those is not super advanced, but certainly not trivial either.

If we go for this approach, the threads in Other Topics will have to be moved to the new sub forums.

I mention this as I was going to ask if topics like Optimization, Dynamical systems and Nonlinear phenomena (or something) could be included under App. Math (Dynamical systems is a pure math topic too, but I haven't seen it listed anywhere), but then I had to ask myself if they were 'advanced university level' topics or not. i.e., I'm not sure if Optimization at the university level is considered 'advanced'. The level of difficulty depends on the non-uniform standard of University education (difficulty is in the eye of the beholder and all that).

Note!! I don't actually think the Pre-/Universisty categories should be removed.. They are aligned with the sites motivation; I'm just speculating .

In my opinion your question about dynamical systems qualifies as

Usually I feel well qualified to answer all questions in

Oh, and since Dynamical Systems is not listed anywhere, Advanced Applied Mathematics does seem to be the appropriate place for it, which is where you posted it.

Oh, and the distinction is not necessarily about the difficulty level, but more about the level of required knowledge.

Some things are just not taught at high school after all.

Then again, some problems that only require high school knowledge, can still be pretty hard to figure out, regardless of advanced knowledge.

Thanks!We don't have'advanced'university levels. Just high school level (pre-university) and beyond (aka university level).

Your question about dynamical systems definitely qualifies asbeyond.

Usually I feel well qualified to answer all questions inAdvanced Applied Mathematics, but in this particular case I was happy to see that Krylov pitched in.

I would like to note that dynamical systems is usually considered a part of the field of differential equations, so the Dynamical Systems description could be added as a tag for the Differential Equations sub-forum. Perhaps in the future when we get more users in science we can add more specialized categories like Physical Chemistry and Fluid Dynamics, but I'm happy with the ILS's proposal.

I like it, too. I will wait for a bit longer, and if there are no objections, I will move ahead and make these changes. Any volunteers for moving threads after I change the forums?
