"This almost seems like magic," writes maths contributor Kevin Knudson for Forbes. "That a formula for π is hidden inside the quantum mechanics of the hydrogen atom is surprising and delightful."

"Nature had kept this secret for the last 80 years," said Friedmann. "I'm glad we revealed it."

Είναι γνωστός ο αριθ

# data[].attributes.body
Είναι γνωστός ο αριθμός π, ο πραγματικός αριθμός που μπορεί να οριστεί ως ο λόγος του μήκους της περιφέρειας ενός κύκλου προς τη διάμετρό του στην Ευκλείδεια γεωμετρία, και ο οποίος χρησιμοποιείται πολύ συχνά στα μαθηματικά, τη φυσική και τη μηχανολογία.

Είναι γνωστή επίσης... ως σταθερά του Αρχιμήδη (δεν πρέπει να συγχέεται με τον αριθμό του Αρχιμήδη). Ο Αρχιμήδης καθόρισε την πρώτη επιστημονικά αποδεδειγμένη μέθοδο με την οποία υπολογίζεται ο αριθμός.

Συνήθως χρησιμοποιείται η προσέγγιση π ≈ 3,14. Τα πρώτα 50 δεκαδικά ψηφία του π είναι:
3,14159 26535 89793 23846 26433 83279 50288 41971 69399 37510

Έχει λοιπόν, αυτός ο αριθμός σχέση έχει με τη μουσική; Δείτε το βίντεο.

It is known that  number pi, the real  number that can be defined as the ratio of the circumference's length of a circle to its diameter in Euclidean geometry , and which is very often used in mathematics, physics and engineering.
It is also known ... as Archimedes' constant (not to be confused with the number of Archimedes). Archimedes determined the first scientifically proven method by which the number is calculated.
Typically approximately n ≈ 3,14 is used. The p first 50 decimal places is:
3.14159 26 535 89 793 23 846 26 433 83 279 50 288 41 971 69 399 37510

What about music and pi?
