noosphere

Etymology

Borrowed from French noosphère, itself built from Ancient Greek νόος (nóos, "mind, spirit") and Ancient Greek σφαῖρα (sphaîra, "ball, globe"); the term was developed, and perhaps coined, by Pierre Teilhard de Chardin and Vladimir Vernadsky on the model of atmosphere, biosphere and the like. Taken at face value, it reads as nous ("mind") plus -sphere.
