Changes

Mosaic split is a [[Scientific Change|scientific change]] that results when one [[Scientific Mosaic|scientific mosaic]] splits into two or more mosaics containing incompatible accepted [[Theory|theories]] or employed [[Method|methods]]. This entails that a previously united [[Scientific Community|scientific community]] bearing a single mosaic becomes two or more communities, each with its own mosaic. Mosaic merge is a scientific change in which two or more mosaics containing incompatible theories or methods become a single united mosaic with compatible theories and methods. This likewise entails the formation of a single community out of two or more[[CiteRef::Barseghyan (2015)|p.202-216]].

Necessary [[Scientific Mosaic|mosaic]] split is a form of mosaic split that must happen if it is ever the case that two incompatible [[Theory|theories]] both become accepted under the employed [[Method|method]] of the time. Since the theories are incompatible, under the [[The Zeroth Law|zeroth law]], they cannot be accepted into the same mosaic, and a mosaic split must then occur, as a matter of logical necessity[[CiteRef::Barseghyan (2015)|p. 204-207]].

Possible [[Scientific Mosaic|mosaic]] split is a form of mosaic split that can happen if it is ever the case that [[Theory|theory]] assessment reaches an inconclusive result. In this case, a mosaic split can, but need not necessarily, result[[CiteRef::Barseghyan (2015)|p. 208-213]].
