No, it does equal three. The measurement was from rim to rim and with a line around the outside of the rim. The diameter of the inside of the bowl doesn't come into it. But it doesn't matter, The kind of account that it is would not be expected to express precice measurements, anyway.
The joke is on the creationists, who scramble for some kind of an explanation for something which doesn't need explaining
Sure, it's just obvious (and I've already posted this before) that it's clearly a wrong way to interpret to attempt to assert that unless the numbers yielded a more precise ratio like 3.14 or such it would prove the bible wrong.
Some people do think that way, and...well, I'll get to that in a moment.
Obviously to me and many of us (as I've posted before) even just a very rough ratio like 3 (rounding down to 3) is good enough, in the context.
This isn't a rocket, but a bowl.
Obviously to you or me or many people it only means the bowl was
about 10 cubits across and
about 30 cubits in circumference.
The text wasn't ever going to be written to some odd sounding non-stylistic number like 9.7 cubits or 30.3 cubits....
And so yeah, it's pretty obvious that anyone getting caught up much in an argument about what is the right ratio
as if it even mattered is a bit off the rails mentally at that moment.
Or maybe all the time (or better case, maybe autistic -- which is better, in that it's not some bad psychology, but just a temperament)...
It's sorta like arguing passionately whether the sky seems crystal blue today or just aqua blue....
I'll sure give you all of that, as it's just what I've already posted before.....,heh heh....
But, in reality we have no clue whatsoever whether they measured their circumference measurement on the inside of the bowl's thickness instead of the outside....
Perhaps the person didn't like it when he measured the outside circumference and got a number that wasn't so rounded.
So he switched to the inside inside circumference a got a more pleasant rounded number close to 30 cubits -- a nice rounded number.
So, in a way then, see the comment in the letter to Nature made sense. It was a point that might help someone overly caught up in autistic thinking where they can't understand why something less accurate than 3.14 is perfectly fine.
