Biofisica quantistica nel cervello umano – CANCELLATO

Devo appurare con un certo stupore, che il mio articolo di qualche tempo fa sulle possibili e molto discusse connessioni fra biofisica, coscienza e meccanica quantistica era stato indicizzato dai motori di ricerca affiancato ad altri siti meno seri e che riportavano diverse notizie prive di fondamento, referenze bibliografiche e serietà.

Da parte mia l’intenzione era quella di dare ad un primo lettore alcuni spunti di possibili letture per approfondire l’argomento riguardante lo studio degli stati quantistici all’interno dei microtubuli, argomento che ad ora non ha trovato risposte scientificamente provate, ma che può essere un interessante spunto di riflessione per chi come come è interessato allo studio dei fenomeni naturali ed in particolare alle stranezze della meccanica quantistica.

 

La vicinanza di questi argomenti alla cultura New Age e ad altre forme di misticismo, animismo e miscredenze simili, mi ha indotto ad eliminare l’articolo dal mio sito, in modo che la serietà scientifica non venga compromessa.

 

 Riporto da wikipedia una lista di letture riguardanti l’argomento coscienza quantistica che cercano di non sforare nel campo New Age…
