Agreed. The Bible is not a textbook for anything technical in the slightest. If anything it's got some good stuff that explains how people function.
Yup ... it's called the long axis.
The Bible gives the circumference (30) and the long axis (10), but does not give the short axis (9.0763[something]) since there's no need to.
Pi has nothing to do with it.
But only if the long axis and the short axis are the same, right?Of course it does. The formula for the circumference of an ellipse *also* includes pi. (A circle is just an ellipse with two equal axes.)
Anything to avoid approximation errors.Now you're inventing precision. The original is only precise to 1 digit. 1.x10^1 cubits across and 3.x10^1 cubits around are compatible with pi and circularity. This is just basic measurement theory.

Then you have a true circle.

As if there was ever an exact cubit or way to measure it.
I don't consider listing two parameters of an ellipse out of three solving an approximation error.Anything to avoid approximation errors.
I'm sure there was. Probably the length from the tip of Noah's middle finger to his elbow, then simply standardized for future use.Estrid said:As if there was ever an exact cubit or way to measure it.
Okay ... thanks.Actually Pi factors into most of the methods of calculating an ellipse circumfrence.

That's cute.Makes me wonder if the ancients had a "standard forearm" stored somewhere.![]()
That's cute.
Do you guys ever think this stuff through?
Establish a length, then preserve it with a piece of string, a strap of leather, a board, length of stone, metal bar, or whatever.

(Round off to the nearest 100th.)
I do indeed.You DO realize that there are technical preserved and calibrated standards for metric units, correct? And that even things like "seconds" are calibrated to features of atomic vibration.
No.Are you familiar with "significant digits"?
Um ... I didn't say round Pi off to its nearest digit.Odprey said:There ya go! If you round Pi to 1 significant digit it is 3. Nothing too terribly hard about that.
I do indeed.
And if we can use something to standardize weights and measures, do you think they could too?
Um ... I didn't say round Pi off to its nearest digit.
Then why did God demand it?Probably not, to be quite honest.
Noah came before they did.Opdrey said:Especially if one uses the idea of a cubit being the same cubit as used by the Sumerians, Egyptians and Israelites which was the length of the elbow to the tip of the fingers.
Then why did God demand it?
Deuteronomy 25:15 But thou shalt have a perfect and just weight, a perfect and just measure shalt thou have: that thy days may be lengthened in the land which the LORD thy God giveth thee.
And how did they accomplish this, if everyone's arms weren't the same length?Assuming Deuteronomy is a legitimate book, those were instructions for the priestly class of Israel, whom must be perfect physical specimens if they were to approach God's altar.
