More about cognoscenti
Cognoscenti 鈥減ersons who have superior knowledge of a particular field鈥� is the plural of cognoscente, which refers to an individual person with such knowledge. Unlike English, French, and Spanish, which usually add -s or -es to indicate a plural noun, Italian typically changes the final vowel of a word; singular -a often becomes plural -e, while singular -e and -o often become plural -i. The Italian verb meaning 鈥渢o know鈥� is conoscere, with the present participle conoscente, which lacks the g of cognoscente; the reason for the g is the influence of Latin 肠辞驳苍艒蝉肠别谤别 鈥渢o know.鈥澛�Cognoscenti was first recorded in English in the 1770s.

With the U.S. and Cuba restoring diplomatic ties, some art-world cognoscenti are betting that the tiny island could become the next hot corner of the global art market.

adjective
existing or occurring within the material world.
More about intramundane
Intramundane 鈥渆xisting within the material world鈥� is based on intra- 鈥渨ithin鈥� and mundane 鈥渃ommon, ordinary, of the earth.鈥� Intra- comes from Latin 颈苍迟谤腻 鈥渨ithin, inside鈥� and is related to interior, internal, intestine, intimate, intrinsic, and introduce, all of which come from Latin terms involving movement toward or existence inside something. Mundane ultimately comes from Latin mundus; as we learned from the recent 51吃瓜 of the Day gens du monde, mundus originally meant 鈥渃lean鈥� before expanding to mean 鈥渆legant,鈥� then 鈥渙rnament,鈥� and finally 鈥渢he world.鈥� A similar shift in meaning happened with the unrelated Ancient Greek word 办贸蝉尘辞蝉 鈥渙rder, government, universe,鈥� as in cosmic and cosmopolitan. Intramundane was first recorded in English in the 1830s.
how is intramundane used?
In fact, correct understanding of the problem of void entails distinguishing two levels: the anthropological and the cosmological, or鈥攖o put it another way鈥攖he intramundane level and that of the totality of being …. For Sartre, this intramundane dimension is essential, and distinct from the extramundane, the void as an infinite milieu.
In Fink鈥檚 view, play, more than work, struggle, or love, provides the 鈥渙perative model鈥� most conducive to revealing the mundanity of the world; … in play, the human being deals not with another, equally real being but with the unreal, such that play is thus always more than mere intramundane behavior.

More about muon
Muon 鈥渁n unstable, positively charged subatomic particle鈥� is a shortening of mu meson; beginning in the mid-20th century, scientists have used Greek letters to identify specific types of newly discovered subatomic particles, and the terms pion and tauon are formed similarly. The Greek letter mu, which is pronounced as 鈥渕ee鈥� in modern Greek and is the ancestor of the Roman letter m, is a borrowing from the Phoenicians, a seafaring people of the ancient Mediterranean. The Phoenician source is the letter 尘脓尘, a relative of the Hebrew letter mem, and both come from a Semitic root meaning 鈥渨ater.鈥� Muon was first recorded in English in the early 1950s.
how is muon used?
Like electrons, muons have a negative electric charge and a quantum property called spin, which causes the particles to act like tiny, wobbling tops when placed in a magnetic field. The stronger the magnetic field, the faster a muon wobbles.
Muons are all around us and are, for example, created when cosmic rays collide with particles in the Earth鈥檚 atmosphere. They are able to pass through matter, and researchers have used them to probe the inaccessible interiors of structures from giant volcanoes to the Egyptian pyramids.
