Folks, could you answer: if I decide to capitalise all subjects (history, biology, informatics, etc.), which is totally optional nowadays, then do I have to also capitalise them when they are used as adjectives and when they are used as sciences?
In order to get my question answered, I asked my English-speaking friends this question, but, unfortunately, none of them were able to answer it, and they advised me that I ask English natives about it.
My [Biology/biology] teacher is evil;
My brother is a [History/history] professor;
In my opinion, [Informatics, Linguistics, Astronomy, and Mathematics/informatics, linguistics, astronomy, and mathematics] are very difficult.
