But in reality we know that it's not irrational. There are no irrational numbers in real life. So, what is the true ratio? How can we find it?
This is the "golden ratio" people don't speak about, isn't it?
Not even a computer can figure out the distance? Is there something wrong with our number system? Is there any changes we can make to our number system to make it easier to calculate?
It blows my mind because if we have a circle with a known absolute circumference, then we draw a line through the center and erase the circle we have a line segment which should be able to be measured.
Is it just a matter of our abilities to measure things not being accurate enough? Most likely. In order to find the true ratio I guess we would have to change the unit of measurement to particles or something, which I'm assuming we don't have the tech to do yet (maybe?)

Because an irrational number is infinite. It's not measurable. Never ending.
Distances are finite. Measurable. Beginning, and ending.

If √2 is rational then you can write it as m/n for integers m, n which have no common factors. Thus m = n √2 and by squaring both sides, m² = 2n². This shows us m must be even. So then there is another integer p such that m = 2p. Therefore 4p² = 2n² which simplifies to 2p² = n² which in turn shows us that n is also even. But if n and m are even, they have a common factor of 2! This is the logical contradiction.
And these can be generalized and give an important and remarkable pair of results for all integers n (positive, zero and negative):
Phi^(n-2) + Phi^(n-1) = Phi^n
phi^n = phi^(n+1) + phi^(n+2)
See what they did there?

Hm, that is not what they are claiming. I will have to study it more as this is the first time I've laid eyes on it.
Pedit: okay so I misinterpreted, read on
So if you take the diameter of a circle and divide it into equal parts (doesn't matter how small you go) and you use that as your unit of measurement, then you will never be able to fit them into the circumference, and vice-versa. You will always have a 'part' that doesn't fit at the end, regardless of how small of units you use.

Guess I'll look into how well things like irrationals amd non-integral rationals convert
It seemed to me, at first glance, they were trying to say any number could be expressed rationally in base phi, which would be really profound, but you're probably right in that effect

You know how we are with our math. It has to be precise. I just can't stand the fact that when dealing with pi the answer is never going to be precise unless you simply don't simplify your answer
Then I feel like if my answer is "2pi" that I haven't finished the problem because that's 2 x Pi = ???
Irks the hell out of me
Guess I just have to get over it and keep Pi in my answers

Next I will prove that Forrest Gump was real and that the government didn't want him as a national hero which is why he isn't in the history books. And you think Elvis Presley came up with those moves on his own?

Second, you can't measure anything exactly. Measuring instruments have limited precision. So any measurement you're going to make is really just a rational approximation to whatever the real length is. It says nothing about whether the distance itself is rational or irrational.

I feel like we've reached a common ground at least.
The next question is whether the following statement is true:
No matter how small of a unit you divide the diameter into, if you try to use that unit to measure the circumference, at the end you will have a space too small for that unit, and vice-versa.
Furthermore, the ratio of that space left over to the unit must be irrational.

Based on what we know, anyway, it must be true.
Why could I not theorize that there is a unit of measurement so infinitesimal that if everything was measured using the unit there would be no irrationality?

I did read some things about einsteins theory of relativity being thrown out as a fallacy (and possibly that he knew it was one). I need to fact check it more myself, and it's a bit off-topic, but did you hear about this and can you confirm or deny it?
Assuming this is true, it seems we almost continuously disprove things that we were universally confident about.
I could then infer the proofs re ratio between a circles circumference and diameter being irrational are simply based on measurements that may have been off by even just 1 of these infinitesimal units, skewing the computations causing the irrationality.

Intriguing. I guess, at this point, I would have to "debunk the Pythagorean Theorum" to show that sure, sqrt2 is irrational, but that there is no proof that this distance could exist.

So if I travel in a straight line in one direction, I would eventually return to original location; much like flying around the earth or any other planet?
