I'm impressed at ChatGPT's ability to generate responses based on regurgitating Wikipedia level facts, but its physical reasoning ability is limited. Here's a discussion I had with it about measuring the circumference of the Earth.

Did Eratosthenes' measurement of the shadows cast at different latitudes accurately measure the circumference of the Earth? [Yes].

Eratosthenes is famous for accurately measuring the circumference of the Earth using a simple method involving the measurement of shadows cast at different latitudes. His method involved measuring the angle of a shadow cast by a vertical rod at two different locations, one of which was known to be on the Tropic of Cancer and the other of which was Alexandria. By using the difference in the angles of the shadows and the distance between the two locations, he was able to calculate the circumference of the Earth to a high degree of accuracy.
[This is true and accurate].

But couldn't the same data be used to measure the distance to the sun under the assumption of a flat earth? [Yes it could].

Eratosthenes' method of measuring the circumference of the Earth would not be applicable for measuring the distance to the Sun under the assumption of a flat Earth. This is because the method he used relies on the Earth being a sphere, with the angles of the shadows being caused by the curvature of the Earth. [That was his assumption; his method doesn't require it, though]. In a flat Earth model, the angles of the shadows would not be related to the curvature of the Earth, and so Eratosthenes' method would not produce accurate results. Additionally, the distance to the Sun is much greater than the circumference of the Earth, so even if his method could be applied in a flat Earth model, it would not be able to provide accurate results for such a long distance.
[I'd quibble on the wording, but not bad. Accurate, but kinda missing the point].

If Eratosthene's method relies on the a priori assumption that the Earth is spherical, can its result be used as evidence that the earth is spherical? [No].

While Eratosthenes' method of measuring the circumference of the Earth relies on the assumption that the Earth is a sphere, the fact that it produces accurate results can still be considered evidence that the Earth is indeed spherical. [No!]. This is because the method is based on sound scientific principles and makes precise predictions that are in agreement with observations. [Absolutely not. It's easy to have mutually inconsistent theories consistent with the same observations. That observations agree with a particular theory does not prove that theory.] The fact that the method produces accurate results despite assuming that the Earth is a sphere provides strong support for the idea that the Earth is indeed spherical. [Nonsense. Eratosthene's results at two points are entirely consistent with a flat Earth. More measurements are required to distinguish between the flat-Earth-close-Sun and the spherical-Earth-distant-Sun hypotheses. Eratosthene's result is ambiguous and inconclusive].

If instead, Eratosthene's started from the assumption of a flat Earth, the exact same measurement could be used to prove that the sun is relatively close to the Earth. How can measurements at only two locations distinguish between the flat Earth and spherical Earth hypotheses?

While it is true that the same measurements used by Eratosthenes to calculate the circumference of the Earth could be used to measure the distance to the Sun in a flat Earth model, these measurements would not be sufficient to distinguish between the flat Earth and spherical Earth hypotheses. This is because the measurements only provide information about the angles of the shadows at two locations, which is not enough to determine the overall shape of the Earth. [Yes! NOW it's got the right answer]. In order to determine whether the Earth is flat or spherical, additional measurements and observations would be necessary, such as the observation of the roundness of the Earth's shadow during a lunar eclipse or the observed changes in the positions of celestial objects over time. These additional observations are not possible in a flat Earth model, which is why they provide strong evidence that the Earth is indeed spherical.
[OK. Better.]

What is the best evidence that the Earth is spherical?

There is a wealth of evidence that supports the idea that the Earth is a sphere, including the fact that the Earth casts a round shadow on the Moon during a lunar eclipse, the observed curvature of the Earth's surface, and the fact that the Earth is a nearly perfect sphere based on its rotation and gravitational field. In addition, the fact that the Earth is a sphere is also supported by the way that gravity works, with objects being attracted to the center of the Earth and the Earth's gravitational pull being stronger at the poles than at the equator. Overall, the evidence for the Earth's sphericity is strong and comes from many different sources, making it one of the most well-established facts in science.

My impression is that the AI defaults to accepting revealed truths like, "the Earth is spherical," and has difficulty understanding or justifying those conclusions or entertaining alternate hypotheses.

Why the traditional family matters.

The crux of the theory is that an individuals’ behaviour will always be motivated towards achieving an optimal outcome, which is determined by self-interest. An assumption made is that the players in such a game are rational, which translates to, “will strive to maximize their payoffs in the game”. In other words, it is assumed they are motivated by selfish self-interests.

Over the years, other contributors such as John Nash (Nash equilibrium) and John Maynard Smith (evolutionary stable strategy) have added to the theory and we are now at a point where it is considered by many to be an essential tool when modelling economic, political, sociological or military behaviours and outcomes, and is taught as such in many prestigious universities as something pretty much set in stone.

But what if we have made a terrible mistake?

Yes, the New York Times finally acknowledged rocket physics after nearly fifty years, but we're still waiting for the Pulitzers to revoke Walter Duranty's prize for his reporting helping Stalin conceal the Holomodor.

Here's ChatGPT struggling with the concepts:
Part 1: t.me/aetherstream/6492
Part 2: t.me/aetherstream/6493

ChatGPT comes off as an annoying midwit, supremely confident that the Earth is spherical but not really understanding how to prove it.

The New Zealand government is trying to take custody of baby Will due to the fact his parents don’t want to use vaccinated blood during heart surgery… they’ve already found hundreds of citizens with non-mRNA vaccinated blood.

Absolutely infuriating. They could easily allow this baby a transfusion of untainted blood but these are the same people who delight in sacrificing children to their god Moloch.

Every time I listen to SBF or his co-workers I am absolutely blown away that any professional investor ever did business with them.

I'm not even talking about what they say... just look at them... listen to them!

Someone thought these were winners?
