Now here’s my broader take on what I’ve begun calling the “knowosphere” — a word intentionally echoing the more allegorical “noosphere,” the “planet of the mind” of Vladimir Vernadsky and Pierre Teilhard de Chardin. Whatever term you use, it’s clear that the world is quickly being knitted by new ways to share observations and shape ideas that are bound to have profound impacts on the quality of the human journey. (“Knowosphere” has also been used by Larry Kilham, an entrepreneur and inventor who has been writing about how to remain innovative in the age of Google.)

Noosphere ( /ˈnoʊ.ɵsfɪər/; sometimes noösphere), according to the thought of Vladimir Vernadsky and Teilhard de Chardin, denotes the "sphere of human thought". The word is derived from the Greek νοῦς (nous "mind") + σφαῖρα (sphaira "sphere"), in lexical analogy to "atmosphere" and "biosphere". Introduced by Pierre Teilhard de Chardin 1922 [4] in his Cosmogenesis".

Another possibility is the first use of the term by Édouard Le Roy, who together with Teilhard was listening to lectures of Vladimir Vernadsky at Sorbonne. In 1936 Vernadsky accepted the idea of the Noosphere in a letter to Boris Leonidovich Lichkov (though, he states that the concept derives from Le Roy).
