Are history questions on-topic for Engineering.SE? [We decided on HSM that history-of-engineering questions are on-topic](https://hsm.meta.stackexchange.com/questions/29/are-history-of-engineering-invention-questions-on-topic) as long as they discuss the applications of specific mathematical and/or scientific principles; History.SE doesn't seem to have discussed it but has [some questions on engineering](https://history.stackexchange.com/questions/tagged/engineering). Keep in mind, though, as [Robert Cartaino said](https://engineering.meta.stackexchange.com/questions/6/our-scope-and-overlaps-with-sister-sites/25#25) (gratuitous emphasis mine),

Just saying. **We shouldn't consider HSM or History in this discussion.** At all. But it's something that may be relevant at some point in the far future, though I hesitate to mention it.
