In the terms of service for Chemistry Exchange, one of the stipulations is to ask or post about “Non-Mainstream Chemistry”. This seems rather vague and up to interpretation. What do they mean by this? Thank you
The question may be closed as opinion based, but my interpretation is :
"Asking about things that are not, figurally or literally, mentioned and explained by many textbooks or educational sites".
It may aby also an "alternative chemistry" ( like alternative medicine), using unexpected,unusual or empirical approach, based rather on curiosity or experience than theoretical reasons.
And yet another explanation is in the @Karl comment. "Non mainstream" as "I do not really know, what I am doing, but let me pretend I do know". A kind of charlatanism/quackery.
