Wikipedia:Articles for deletion/Non-Newtonian calculus
I'm glad this has come up for deletion because ironically the topic has thereby caught my attention. This topic has been referred to in a mathematical journal, so it's notable enough as far as I'm concerned. So what if this is a "what if?" kind of thing? The usefulness remains to be seen, but wikipedia is not just for practical information. The word 'fringe-y' theory is mentioned above but the word fringe describes theories held by a small minority which contradict widely accepted theories and are thus rejected, however that is not the case here. This does not contradict anything, it is simply not widely known about. The word fringe does not apply. There may be a so-called COI, but really that just means the article should be subjected to close scrutiny. It is not a reason for deletion. Wikipedia would be a very much poorer place if articles like this are deleted. The fact that it has been referred to in a journal means that  does not apply
