I am writing an article for an audience that mostly consists of computer scientists. A specific part of the subject is motivated by Kirchhoff's laws. I intend to mention this fact and reference the rules. But that is easier said then done. Apparently, Kirchhoff predates referencing.
How to reference a source that is so old, it has no bibtex entry, but is also probably not well-known throughout the readership?
edit: I want to clarify, that I can also imagine to not reference it at all, but I find it difficult to draw a line here. Can I assume that every reader is familiar with a term? For instance, can I omit a citation to Damas/Hindley/Milner when introducing ML to modeling engineers? How about Newton's method for computer scientists?
