I am definitely doing applied math and here my two cents: In applications of mathematics one has to face a lot of questions and issues that are not really mathematical like modeling of real world phenomena, tuning parameters in models or algorithms, software engineering or issues of implementation. Of course there are mathematical theories involved in all ...

I wrote the top-voted answer to this question on MO (it currently has something like 40 up votes) and was a bit surprised to see it migrated to HSM. I don't care about votes or what-not, but in terms of the content of the question and answers, I actually think that this question does belong on MO. It's a question frequently asked by budding researchers in ...

I voted to close. Mathematics can be used in many other areas. However, the field of applied mathematics is different from the collection of all applications of mathematics. When you can't figure out what is going on in a chemical system, sometimes the problem is with your understanding of the relevant chemistry instead of the analysis of a mathematical ...

You can flag the post for moderator attention on MSE, choose the free-form flag and ask for a migration to MO. Another option, which is useful when the crickets really chirp, and you haven't got any comments either, is to simply delete the question and post it anew on MO.

I would have nothing against such a question on MO. My guess is that it would be well received here. But I'm not a specialist in the topic, so you should not go by my word only. If you migrate it from CST to MO, you will lose your CST audience. If you feel that the MO community probably cannot answer all aspects of the question, it might make sense to cross-...

A near duplicate of Manishearth's answer, showing the same graphs but with 7-day moving windows per François' suggestion. I think it's much clearer: My data is copied from Manishearth's with a few columns added to do the calculations. You can grab a copy and do further manipulations yourself.

One issue with cross-disciplinary questions such as this one is that they are often vague. Regardless of what disciplines are involved, such questions have a very slim chance of surviving on MathOverflow because they have a too broad range of interpretations. The odds that 5 voting users interpret the question in a way that they find off-topic are very high, ...

Thanks for bringing this up! I agree that there are many migration-worthy questions that are closed in a suboptimal way. As I was one of those who voted to close your example question "for wrong reasons"1, let me tell how I try to use the different off-topic closure reasons: Generally off-topic: I only choose this option if the question should not be asked ...

This question was asked on MO on May 8 and moved to HSM on May 13. It currently (May 25) has 5 answers, all posted on MO (between May 8 and May 10), and all upvoted (currently from +6 to +44; I can't check exact count because I've got a minimal rep on HSM). It seems to me from the discussion that there is a large consensus that this question was on-topic at ...

History of Science and Mathematics moderator here. We've talked it over and have just sent the question back to Math Overflow (I closed it as off-topic on HSM, so that should bounce it back to MO automatically). Over the last six years, we've had a lot of conversations with other STEM sites about their chosen policies on historical questions and what any ...

My memory of what happened is this: I was pinged to come over to the moderator chat room and was asked if we "wanted" three MSE posts to be migrated. I said I wasn't sure about the post in question, meaning I wasn't sure whether actual experts would keep it open if it were migrated -- the MSE moderator took that as a "no". I told the other MO moderators what ...

The phrasing of the reason is unfortunate, IMO. It makes sense to migrate if a question is better suited to MSE; it doesn't necessarily make sense to migrate just because the question can be answered on MSE. In what follows, let me pretend that the wording "can be answered" has been changed to "better suited" since that may have been ...

I updated the meta post. Another byte by byte copy of that question existed on Math SE prior to the migration, which is why it was automatically rejected by the system. We do appear to log this, I'm going to investigate getting the reason for the automatic rejection to be visible in the question's timeline that is visible to moderators. I'm not certain ...

I think that questions in applied mathematics and mathematical modeling/understanding of issues from other sciences are suitable for MathOverflow and such questions should be encouraged. In my opinion UwF's Mpemba effect question is an excellent question of this type.

You can read all about migration and how it works here: What is migration and how does it work? As explained at that post, migrations should be done with circumspection; for a variety of reasons it's not a good idea to migrate something which is likely to be closed at the receiving site. Therefore the people best placed to judge when migration is ...

The question on MathOverflow has been restored. The corresponding question on Meta.MathOverflow has been deleted.

Yes, it's possible, but as Anna Lear explained in an earlier answer, there are some requirements. There needs to be a clear pattern of questions to be migrated and the migrated posts need to have low rejection rate on the target site. In the mean time, if you need to have a post migrated, just flag the moderators and explain the situation. Moderators can ...

I already set this up earlier today, so... enjoy!

You can't migrate an answer without migrating the entire thread, which is entirely inappropriate at this point. You can encourage Joel to take his question to Math.SE, and if there is no suitable question on which he can post it, then he is more than welcome to formulate his own question and post that answer below it. In either case, moving only an answer is ...

Perhaps the etiquette should now be to write comments with the expectation that such questions will be migrated. For example, a comment could be: "This question is better suited for math.stackexchange, rather than mathoverflow. I recommend it be migrated to MSE."

I am not an expert on the topic, so I can't tell if the question could be edited to make it on-topic. Typically questions that ask for homework help are not received well here, but exceptions are possible. It seems to me that the question would be fine at MSE and could have been migrated, but others may disagree. People who vote to close are often hesitant ...


5

I don't think the question would be good at MO. I would vote to close it as off-topic, and believe so would many others. I see no particular research angle to the question, and I would not consider it otherwise interesting to research mathematicians, either. That said, I gave you something of an answer at MSE. I don't know if my way qualifies as a nice way ...

From the FAQ post on migration: What is migration and how does it work? (in the section "Anything else I should know about migration?"): Comments on the question that link to the homepage of the target site will be deleted. This is to remove redundant comments that tell the author to post on that site. It is consistent with the linked post. In this case ...

My understanding is that the post was originally flagged with a migration request and one of our moderators processed the flag to meet that request. No, the OP did not ask for that migration; it was someone else who raised the flag. (At the time I was taking a little but much needed break from my usual level of moderator activity, and told my fellow ...
