La Turquoise du Sud-Ouest : un dépôt géologique rare entre science et légende

January 25, 2025 no comments Posted in News

Définition et origines géologiques des gisements de turquoise dans le Sud-Ouest français

Contrairement à une croyance populaire, la turquoise n’est pas une pierre commune dans le Sud-Ouest français, mais ses dépôts localisés relèvent d’un phénomène géologique fascinant. Formée principalement dans des environnements arides ou semi-arides, la turquoise résulte d’une altération hydrothermale de roches riches en cuivre, souvent associée à des altérites où le cuivre dissous se précipite en présence de phosphate et de carbonate. Dans le Sud-Ouest, notamment dans les massifs du Quercy ou du Massif Central, ces conditions ont permis la cristallisation de cette pierre bleue translucide, rare par sa couleur intense et sa formation lente, sur des millénaires.

Il paradosso di Banach-Tarski: un mistero geometrico che sfida l’intuizione

a. Il paradosso di Banach-Tarski, scoperto nel 1924 da Stefan Banach e Alfred Tarski, rappresenta uno dei capisaldi della geometria moderna. Esso afferma che una sfera solida può essere scomposta in un numero finito di pezzi, ricomposti attraverso rotazioni e traslazioni, in due sfere identiche alla sfera originale.
b. Ma come può una figura finita diventare due sfere? Il risultato sembra impossibile, ma si fonda su basi rigorose della matematica moderna: in particolare, sulla teoria della misura e sull’esistenza di misure non additive, come la misura di Lebesgue.
c. In spazi infinito-dimensionali, dove l’intuizione geometrica tradizionale fallisce, questa teoria garantisce la coerenza delle operazioni matematiche, rendendo possibile ricostruire strutture complesse senza contraddizioni. Read more
