Where it comes from
Borrowed from French noosphère, from Ancient Greek νόος (nóos, “mind, spirit”) + Ancient Greek σφαῖρα (sphaîra, “ball, globe”), developed and perhaps coined by Pierre Teilhard de Chardin and Vladimir Vernadsky, in analogy to atmosphere, biosphere etc. By surface analysis, nous (“mind”) + -sphere.
