HashNode is a pretty good site for stuff related to programming in general. Articles on engineering tend to have a much more formal tone than ones here. HashNode is more of a small community of software devs than a formal wiki or Q/A forum like StackExchange.
If you ask a really hard science question here, you have to be really lucky to get an answer. You are free to write scientific articles here related already indirectly to computer science. I think they should get a decent reading.
Bottom line: Everything is allowed, no one will stop you. It might not be appreciated though.
P.S. I love engineering and science, but this is a community, and I'm trying to talk from its perspective.
