Pi in the Bible first came to my attention (if my memory serves me right) in a math book - Number Tobias Dantzig.
With this endorsement:
“Beyond doubt the most interesting book on the evolution of mathematics which has ever fallen into my hands.”Albert Einstein
Quite appropriate for Pi Day and Einstein’s birthday.
“Quite appropriate for Pi Day and Einsteins birthday.”
Also the anniversary of Stephen Hawking’s passing.
