Morning MJ:

This is like a broken record...I will repeat.
Pi, as known before the advent of computer, was "commonly" known and used as 22/7...that is what I was taught in math many years ago. And, according to the approximate age you profess to be, you were taught likewise.

For you to "slide" a series of decimals into this subject does not get you off the hook. We, and I am talking of the general public to represent this group, perform mathematical operations using a calculator; it's a no-brain process, done automatically. The numbers are entered and the results are given showing a series of decimal places that many tend to use to represent their case. They are not stating that pi was known to the AE as 3.141592654.
You find the person(s) who claim the AE did know pi to this accuracy then you have a case...but for all the years I have ventured and all the people I have discussed with on the internet, I know of none.

You and several others, as mature participants, must learn to accept that the word pi is a "number" comprising of an integer and a fractional/decimal segment attached; it represents the number of times the diameter encircles the circumference of a circle...be it 3-1/7, 3.14, 22/7 or whatever you wish to use...it’s mathematically symbol is the Greek letter "p" that modern individuals pronounce as "pi".

This is good, but you must provide the proof. What evidence do you have? Your last topic posted re: pi was lacking of evidence, confusing to read and poorly presented. To include the RMP problem #50 was unwise since you depend solely on other individuals and their concept of the written words of the text. You can't read it yet you claim full understanding of its purpose...IOW...it's hearsay.

This is not true, according to your mathematical "experts", these same individuals whose writings you follow faithfully with blinkers set in place, state different.
These "wizards" claim the AE didn't know how to "multiply" or "divide"...remember?
But that is an incorrect "assumption" on their part...you and I know that...right?

A tongue-in-cheek statement with absolutely no foundation or merit attached to make it worthy of discussion. I would suggest you drop it from your list of four.

One out of four is not what I would claim “consistent”...far removed.

Done.

Best.
