First time in history,measurement in the geometric field

[Bored chemist]

You need to do this

 before anyone here (apart from the resident crackpots) is going to pay you any attention.

You are right and you can always argue that the measurement is not accurate.
Therefore, I propose that a recognized scientific institute conduct my experiment.
This experiment will go into history, and it will prove that pi varies from 3.1416 to 3.164

thanks

Albeit in three dimensions, this experiment verified the value of pi to 30 parts in a billion

And their improved method got within 20 parts per billion.

All hell would have broken loose if they had discovered discovered that it was wrong.
So, we can conclude that you are wrong.

I'm not mistaken, because even logically a pi must change.
The change is in a tiny field, but it exists.
This tiny change can detect the device in the article.
No scientific institution has used such a device.
I invite such an institution, to conduct a historical experiment.
The results will be - an earthquake in science.

"I'm not mistaken, because even logically a pi must change."
Are you saying the ratio is different for big circles and little circles?

[aetzbar (OP)]

Yes of course

[Bored chemist]

OK.
How do you explain the fact (and it is a fact) that the measurements show that you are wrong?

Also, imagine I take a ring and hold it near a small bright light so its shadow falls on a distant wall.
It's simple geometry to show that any measurement made on the shadow is proportional to the same measurement made on the ring.
And if the ratio of the diameter to the circumference of the ring is pi then the ratio of the circumference to the diameter of the shadow will also be pi (both numbers  get bigger in the same proportion).
But the shadow is a much bigger circle than the ring.

You are just wrong.

We are at a stage where words are not helpful.
Only a practical experiment will determine whether  pi changes or is fixed.
thanks

The experiment has already been done.
I pointed this out to you already.

You are wrong.
