Flat Earth debunkers (and skeptics in general)

acenci said, "Unfortunately, at the moment, the debate can only be limited because the active users are only 3 or 4. cal is partly a concave earther (in some respects) and partly a flat earther (in other respects), heathen is a flat earther, and so is dionysios and has been for a long time."

Not one flat earther has a clue what their own map is and not one of them can answer the questions asked....not one of them!

1. How is it made?
"A point on the globe is chosen to be special in the sense that mapped distances and azimuths from that point to any other point will be correct. That point, (φ₁, λ₀), will project to the center of a circular projection, with φ₁ referring to latitude and λ₀ referring to longitude. All points along a given azimuth will project along a straight line from the center, and the angle θ that line subtends from the vertical is the azimuth angle."
en.wikipedia.org/wiki/Azimuthal_equidistant_projection

2. How is it used?
"It is useful for showing airline distances from center point of projection and for seismic and radio work. In the case of radio, this projection allows for directional antenna aiming, especially in the case of HF communications. An operator can point the antenna, usually by an electric rotator, simply locating the target in the map and rotating the antenna to the angle indicated by the map. The map should be centered as nearly as possible to the actual antenna location." en.wikipedia.org/wiki/Azimuthal_equidistant_projection

(1) Azimuthal. "Having a constant distance/scale from the point of tangency. Thus if a harbor or airport is selected as the point of tangency, the great-circle course, distance, and track from that point to any other point are quickly and accurately determined."
(2) Communication. "The path of an incoming signal is at once made apparent if the direction of arrival has been determined, the direction to train the antenna can be determined easily."
(3) Navigation/Star Finder. "The projection is also used for polar charts and for star finder."

3. What is its purpose?
(1) To determine Latitude and Longitude. "By bringing either of the indicator arms to any given point, the latitude and longitude of the said point may at once be determined without future computation."
(2) To determine the time of day. "In order to ascertain the time of day or night, in any part of the world... You have now got the absolute corresponding difference of time..."

4. Who uses it?This projection is used by the USGS..."
en.wikipedia.org/wiki/Azimuthal_equidistant_projection

5. Where is it used? Anywhere.
"Celestial Navigation is the art and science of navigating by the stars, sun, moon, and planets, and is one of the oldest of human arts. With the rise of radio and electronic means of finding location - especially with the increasingly popular GPS, based on satellite transmissions that can tell us our latitude and longitude within feet - knowledge of celestial navigation has experienced a precipitous decline."

+Cal Piso Nice copy and paste job...but you at least proved you can look something up. I was hoping for a more informal explanation but your answers are correct, how could they not be...they are not yours but from official sources...the big question is...does this prove to you (if you are a flat earther, which I do not know) that the map flat earthers use does not prove the earth flat. I know a map does not prove shape one way or the other, but it should prove that flat earthers have hijacked something they do not even understand.

And another question is...do you understand what you copied...since it is not in your words or any layman terms I wonder if you actually understand the map.

You are right about the Flat Earth Community in general. Yes, they take the Azimuthal Equidistant map as flat earth gospel. They are typically ignorant of true geodesy and geomatics. And your assertion that they have hijacked something that they do not understand is absolutely correct. Alexander Strahan Gleason was a Civil Engineer, as am I.

Your question: "the big question is... does this prove to you... that the map flat earthers use does not prove the earth flat. I know a map does not prove shape one way or the other..." Absolutely, this map does not prove that the earth is flat. As you have noted, it just shows that anyone who uses it (the FE community in general) does not understand geodesy, and simply shows their ignorance by their blind use of it.

IMHO by and large the flat earth community is unwilling and sadly, perhaps unable to define their terms. And given the conspiratorial nature of the movement, I don't think we will see a rational explanation of the shape of the earth widely promulgated any time soon.

However, a variation on your question could be "does this map prove to me that the earth is not flat." And here I would have to answer that question in the negative. But again we must define our terms. I will say this, that the earth is flat, yes, but it is not a disk.

And here is my challenge to you. (1) What is the true shape of the earth? (2) How can the earth be considered flat and yet have spherical surface distances? (3) Who was the founder of this concept?

+Cal Piso I was with you and about to compliment your answer until you said ... I will say this, that the earth is flat, yes, but it is not a disk. So I am not sure who you are anymore.

1) Oblate Spheroid. 2) It cannot. 3) Which concept?

You are not sure who I am anymore?
1) Oblate Spheroid. The earth has similar characteristics to an oblate spheroid, but no this is not the right answer.
2) It can. Your incredulity shows that you do not understand what is going on.
3) Which concept? Again, your answer shows that you do not understand geodesy and by implication, cosmology.

1) yes it is the right answer and you are wrong
2) nice trick question...the earth is not considered flat under any circumstances...it is always a sphere...can I consider a small portion flat for certain purposes? Yes. Such as the footprint of a building. Or can nautical miles be use at the same time as statute miles...yes...can airspeed be compared to ground speed yes. Other then that it was obviously a trick question in which you hoped to trap me.
3) How is it that you asking me if I understand a concept without telling me the concept gives you the power to make ridiculous assertions about my knowledge...you are fucked on this one!

So let us recap...you copied and pasted all your answers...not a one was from your mouth...so how do I know you even understand them...I do not! Next you ask vague questions in order to use them against me. Third you claim to be an engineer...I now highly doubt that...you are talking to an engineer and it is pretty easy to tell the bullshitters from the real deal...I do not think you are the real deal

So you have a troll channel, how am I not surprised

+Cal Piso I think you are full of shit, copied answers, questions which were intended to trick me and which you got wrong anyway, your claim to be a civil engineer but yet displayed the arrogance of a kid just out of high school, using terms that a civil engineer would not normally use to sound smart, instead of proving your answers to your own questions you want an off page debate. But the worst one was asking me who the founder of a concept was without defining the concept and then acting like I am stupid because I did not answer a question that was very badly asked and could never be answered. Grow up...you have a point then make it...but I think you are just another full of shit flattard.
