The question asks, in part:
In what way can the irrational and infinite number Pi be derived from the written Torah?
The answer is:
Pi can be derived from the Torah by rolling up a Torah scroll and measuring the end's diameter and circumference. The ratio between them will be pi.
What action, if any, should we take? ("None" is of course a possible answer. I'm not advocating anything in this question; I'm asking a question for community discussion.)
