Yeah

2018-09-14 05:07:31 UTC  

It's kinda laziness then?

2018-09-14 05:07:32 UTC  

That's the jist of it

2018-09-14 05:07:40 UTC  

Well, think of it this way

2018-09-14 05:07:47 UTC  

Diminishing returns on investment

2018-09-14 05:08:03 UTC  

You could correct all the problems but if they're not really problems because you don't need the precision why bother?

2018-09-14 05:08:13 UTC  

Okay that makes sense

2018-09-14 05:08:29 UTC  

"One is an analytical approach using a flat-Earth approximation to predict geopotential information quality as a function of spatial wavelength."

2018-09-14 05:08:37 UTC  

¯\_(ツ)_/¯

2018-09-14 05:09:06 UTC  

Could you sum up why this paper isn't FE proof like in a sentence or two?

2018-09-14 05:09:25 UTC  

I'd try but I'm a little lost reading your simplification

2018-09-14 05:09:48 UTC  

He basically summed it up with the satellite statement he made initially

2018-09-14 05:10:51 UTC  

It's a FE proof which requires space and satalities

1. We use a lot of approximations in controllers
2. Assuming a flat stationary non-rotating plane is a decent approximation.
3. Experiments report cumulative error
4. Large experimental errors are telltale of large appoximation components.
5. It's a satellite in orbit. Contradicts the point.
6. Most papers quote their approximations.

2018-09-14 05:12:31 UTC  

For information gathering purposes, a flat plane with all data directly displayed in relation to its surroundings makes for an easier and more efficient system. The plane contains only about 30% of the known area of the earth, and the paper specifically cites the cases and reasons for why the Flat model used has situational advantages over a spherical or elliptical model. It is not an FE proof.

2018-09-14 05:12:37 UTC  

If using satellites to prove the earth is required then you've accidentally accepted that sallites are real and in orbit

2018-09-14 05:12:42 UTC  

So you'd have to reconcile that too

2018-09-14 05:12:53 UTC  

Orbit in turn demands gravity

2018-09-14 05:13:15 UTC  

If satellites were balloons they wouldn't call it an approximation

2018-09-14 05:13:28 UTC  

It would just be the flight controller algorithm

2018-09-14 05:13:56 UTC  

The papers would instead be all about controlling lighter than air objects in winds

2018-09-14 05:14:07 UTC  

*They're not*

2018-09-14 05:14:30 UTC  

Which has nothing to do with the shape of the earth.

2018-09-14 05:14:34 UTC  

🤔

2018-09-14 05:14:34 UTC  

Exactly

2018-09-14 05:14:42 UTC  

Well, it does a bit, but

2018-09-14 05:14:47 UTC  

It's not important here

2018-09-14 05:15:17 UTC  

Wind patterns, I suppose, but that still works on a flat plane via projections

2018-09-14 05:15:59 UTC  

Doesn't seem that damming anymore

2018-09-14 05:16:10 UTC  

If anything it's pro Globe

2018-09-14 05:16:24 UTC  

🤔

2018-09-14 05:16:52 UTC  

Honestly, If we live on a globe, I don’t see how using the flat earth model is helpful in any analysis of data. If it’s a globe, it’s not useful. Irresponsible, actually.

2018-09-14 05:17:07 UTC  

Quite the opposite

2018-09-14 05:17:32 UTC  

When a model can be simplified, the margin for error is reduced.

2018-09-14 05:17:44 UTC  

There are simply less steps and less variables

2018-09-14 05:17:52 UTC  

It allows things to be carried out more quickly to the much the same standard, if not better in some cases

2018-09-14 05:17:56 UTC  

This makes calculations more reliable

2018-09-14 05:18:05 UTC  

It's thinking smarter and not harder

2018-09-14 05:18:06 UTC  

And more reliable is almost always superior

2018-09-14 05:19:29 UTC  

Tbh, if I want to study data for the globe...I would probably want to use the globe model. Your suggestion that it’s the easy way. Well, that idiotic. The easy way is never the right way
