Curvature of a ball is deviating from the level line of the starting position with distance squared. Otherwise it would be a straight line, not a curve!

First mile is 8 inches, than second mile 32 inches, third mile 72 inches and so on.

Actually, that's the parabolic approximation to the curve.
But it's not the point.

Do you accept that the air is thinner at altitude and will therefore have a lower refractive index?

Utter mathematical rubbish.

It is devaiting with every single micrometre, picometre or attometre.

Did you not read or not understand the formula I gave and subsequently worked out for you ?

The deviation is measured in length units not area units.

That is all there is to it.

Al they are saying is that, to a rough approximation, the deviation is roughly proportional to the square of the distance over which the light travels. They are approximating the curvature by a parabola. It's not a desperately  bad approximation.

Inches per mile squared is an odd unit, but ...

 

But their claim that air is homogeneous is ,wrong, only slightly, but nevertheless, wrong.

And by an interesting coincidence, the effect almost exactly cancels out the curvature of the Earth.
Which explains their experimental results (without resorting to stupid stuff like a flat Earth).

 I am part of FECORE and this experiment.

It's very important to distinguish between volume density and optical density. For the optical density profile calculation and the direction of light bending, only optical density is important.

In normal conditions - temperature decreasing upwards - the light is bent upwards in levelling refraction (near horizontal measurement), towards the optically more dense colder air.

No it wouldn't.

Light bends at the border of mediums with different refractive indexes. Light does not bend in a homogenous medium.

Close to the surface of a large body of water, it is very common to have an inversion, whereby the cool water cools the air immediately above. So then it would not be true that the temperature decreases upwards within the layer.  The opposite would be the case. For example this explains why Chicago is sometimes visible from a point 60 miles way on the far side of Lake Michigan. It is what is called a superior mirage, and its cause is the bending of light in an inversion layer above the lake: https://www.abc57.com/news/mirage-of-chicago-skyline-seen-from-michigan-shoreline

Thank you for your explanation, which is true mathematically.

But the way that this is being presented is not, since it hides the fact that the constant of proportionality has units of its own to make the expression of proportion dimensionally correct.

Also not being made plain is the fact that this is also the correction for curvature alone.
A suitable correction for refraction also need to be made or accounted for in the methodology.
The refraction correction is of the opposite sign to the curvature correction.

We went over all this extensively in the last thread that was closed and FECORE are repeating their misunderstandings from 2016.

I also went over effect this in the last thread, my experience in the Arabian desert being the one where two theodolites were performing reciprocal observations (observing each other) and both recorded a small positive vertical angle, thus suggesting each was 'above' the other.

That's interesting. In the desert I'd expect an inferior mirage, e.g. the sky being seen as at ground level, so I'd have thought you would each see the other lower than they really were. Or was this at dawn, with cold ground?

I wonder if Sandor will come back.

I was sort of hoping my example of Chicago might deter him. I have actually seen that example used by flat-earthers elsewhere, as "proof" the lake is flat. So I thought I would pop that bubble before he had a chance to refer to it. 

The psychology of these people is what intrigues me. I suppose it may just be contrariness: a determination to be agin everyone else, just for the hell of it. But it is very strange. Makes QAnon look normal - almost. But I digress.......

My recollection is that back in the 50s and 60s Flat Earthers were tweed wearing, pipe smoking, avuncular and eccentric Englishmen. There was a sense that their claims were tongue in cheek and motivated by a desire to make retirement more interesting. It was all rather charming. But perhaps that is a flawed recollection. Anyone else have similar memories?

The first time I heard someone arguing for a FE, it was a religious argument that went beyond eccentric. From everything I've seen lately, the religious perspective has been spread by the popularity of YouTube. Like creationists before them, the FE proponents add in a slurry of misunderstood science and flat out lies to fool those who know no better.

The flat earthers are at their core just more conspiracy theorists who believe all the worlds governments have gotten together and decided to hide the truth that the earth is flat.  Why they think that truth is being hidden is beyond me.

I can't say I had ever come across them, until a few years ago on the internet.

Anyway, it's nice to know one can always annoy them by asking if it is true that the Flat Earth Society has members all around the globe. This seems to be a meme they can't kill off.

Nice one. (I can't believe I've never heard it before!) I imagine the remark will send the more volatile Flat Earther into orbit, leaving them with even more intense cognitive dissonance.

I just recently saw a video where someone examined an "experiment" done by FE proponents, Dealing with looking across a large body of water at a building. They worked out how much of the building "should" be hidden by the curve, and then pointed out that more of the building was seen than predicted by there being curvature.

The examiner pointed out two things:

1. They failed to take into account refraction( as mentioned in earlier posts).

2. The ground floor of the building was not itself at water level, but several yards above it.

Once these were taken into account, the amount of building they saw matched the predicted curvature.

But the other more interesting thing he pointed out was that, In their own video, some of the building was hidden below the horizon.   With a flat Earth, all the building should have been visible.  They never even address this and sweep it under the rug.   This is typical of the type of intellectual dishonesty they indulge in.

Some of the other stuff I've seen makes me me wonder if they just competing to be the poster child for the Dunning-Kruger effect.

I would like to recommend a laser experiment that reduces error and will hopefully eliminate tricks.

Recreate the Alfred Russell Wallace/John Hampden Bedford level experiment of 1870, with a laser instead. 

Simply place the laser (purple preferably) with its culminator, where Wallace placed his telescope, at Welney bridge, with beam exactly centered 13 ft off the water, at Welney bridge.

Aim the laser down the canal to strike the Old Bedford bridge 6 mi away, centered exactly 13 ft off the water, with a fluorescent yellow disc approximately the size of a softball. this will eliminate (quite handily) any atmospheric apparitions that might present themselves like inversions or refractions due to the height of the beam above the water.

At a distance of three miles away, at a railroad bridge location, post two targets... One at 13 ft off the water, a small circle roughly the size of a baseball, bright fluorescent GREEN.

Lower on this same arrangement have a rectangular Target where the top will be 9 ft off the water and the bottom will be 5 ft off the water, and this target will be fluorescent RED.

Have this target be folded, so that when first deployed it will bend over to 90° angle to be in part, parallel with the water, having a hinge (maybe at the 4 foot location, 4 ft off the water... 

So that while aiming the laser, the center targets (at 3 miles) are out of the way, and not obscuring the laser aiming process. 

Then in a live (untested) facebook/youtube event... Release the center targets to stand upright and block the laser beam.

And simply observe which color lights up the brightest.

There will be beam divergence of course but hopefully that can be reduced to a minimum.

I'm sure FECORE would love to try this with no tricks?

There is another location they could do this as well, however, the Bedford level location is quite historic, being done at the original Bedford level experiment place in England.

The original Bedford level experiment (executed by Rowbotham) was improper because it allowed atmospheric refraction to discredit the results.

So? How about it? @Dr. Zack
