STOPThe calculations of Muslim astronomers were so accurate that in the 9th century they reckoned the Earth's circumference to be 40,253.4km - less than 200km out. The scholar al-Idrisi took a globe depicting the world to the court of King Roger of Sicily in 1139.
The system of numbering in use all round the world is probably Indian in origin but the style of the numerals is Arabic and first appears in print in the work of the Muslim mathematicians al-Khwarizmi and al-Kindi around 825. Algebra was named after al-Khwarizmi's book, Al-Jabr wa-al-Muqabilah, much of whose contents are still in use. The work of Muslim maths scholars was imported into Europe 300 years later by the Italian mathematician Fibonacci. Algorithms and much of the theory of trigonometry came from the Muslim world. And Al-Kindi's discovery of frequency analysis rendered all the codes of the ancient world soluble and created the basis of modern cryptology.
In 850, al-Farghani wrote Kitab fi Jawani (meaning "A compendium of the science of stars"). The book primarily gave a summary of Ptolemic cosmography. However, it also corrected Ptolemy based on findings of earlier Arab astronomers. Al-Farghani gave revised values for the obliquity of the ecliptic, the precessional movement of the apogees of the sun and the moon, and the circumference of the earth. The book was widely circulated through the Muslim world, and even translated into Latin.[17]

The period when a distinctive Islamic system of astronomy flourished. The period began as the Muslim astronomers began questioning the framework of the Ptolemaic system of astronomy. These criticisms, however, remained within the geocentric framework and followed Ptolemy's astronomical paradigm; one historian described their work as "a reformist project intended to consolidate Ptolemaic astronomy by bringing it into line with its own principles."[18]
Between 1025 and 1028, Ibn al-Haytham wrote his Al-Shukuk ala Batlamyus (meaning "Doubts on Ptolemy"). While maintaining the physical reality of the geocentric model, he criticized elements of the Ptolemic models. Many astronomers took up the challenge posed in this work, namely to develop alternate models that resolved these difficulties. In 1070, Abu Ubayd al-Juzjani published the Tarik al-Aflak. In his work, he indicated the so-called "equant" problem of the Ptolemic model. Al-Juzjani even proposed a solution for the problem. In Al-Andalus, the anonymous work al-Istidrak ala Batlamyus (meaning "Recapitulation regarding Ptolemy"), included a list of objections to the Ptolemic astronomy.
Random Islamic knowledge pertaining to current post look into inshallah :)
And that was still all predicated upon the globe. There was a time that humans knew the earth was a glob, however, because we had not invented telescopes as of yet, we had no way to confirm stellar parallax, and they understood quite well that stellar parallax MUST occur if the earth were moving around the sun. Once telescopes were invented, humans were able to confirm stellar parallax existed, and was able to be measured. Since that time, the heliocentric globe model was confirmed as a fact, and has been reconfirmed as fact millions or billions of times since then based on thousands of observable phenomenon.
You are welcome to observe and measure stellar parallax yourself, as one way we know for 100% fact the earth is, in fact, revolving around the sun, as well as hundreds of other easy observations that amateur astronomers do every day.

Looks like @reneyusufbey was on your side @kerriknox lol
Very good thank. Keep up the good work.
this doesnt debunk flat earth lmao
It's a rebuttal to their claims. It shows that there is zero evidence for an ice wall. Which debunks flat earth claims, and debunks their entire model.
so your saying because of you have not been presented with evidence for an icewall so that debunks the shape of earth? this proves neither family. just because 1 group of people may adopt a specific model , that doesnt mean they speak for everyone, im not into the bandwagonism aspect of the subject, but likewise there is no real evidence for a globe either , so a person is only right or wrong here by consensus, and not actual fact. Are you doing independant research or are you just regurgatating what you learn from a text book, you yourself have no evidence of your own, anyone can make up equations , and put theories together to suit their ideology, this is nothing new. At the end of the day , the idea of a flat earth preexisted the globe , so you all have to prove a ball , i dont have to prove original design :)
a. I'm not saying that I haven't been presented with evidence of an ice wall, I'm saying that the mounds of evidence that actually exist refute the existence of an ice wall.
b. Why are you repeating that I am saying it debunks a flat earth when I made no such claim? I did not say the non-existence of the ice wall debunks a flat earth in general, I said it debunks their claims and the accepted model. I said it that way because I UNDERSTAND that it does not.
So, why did you bring that up again? You say you are not into 'bandwagonism', yet you repeated a claim that I did not make twice. That IS 'strawmanism'. Disclaiming one logical fallacy while invoking another is not a virtue.
And yes, there is so much overwhelming evidence for a globe that is it impossible to miss if you bother to look for it. I have provided several very specific observable proofs of the globe that DO debunk any and all flat earth models, right on my Steemit blog alone.
I can provide a list with proofs of close to 2000 observations that prove the globe, most of which are impossible on ANY flat earth model, these observations are such that anyone can make and that JUST a group of us have compiled ourselves from our own observations. Read that again: close to 2000 simple observations that prove the globe that humans have been observing for over 2000 years.
You parrot the platitudes that I am regurgitating from a textbook, when it is actually you who are parroting the flat earth cult talking points. Also, to say that you do not have to prove anything is just scientific illiteracy and shifting the burden of proof (second logical fallacy). No model is a 'default' model, regardless of whether you wish that to be so or not. Also, argument to antiquity is another fallacy. So, you decried one fallacy while actually making that fallacy yourself, and then invoking three more!
EVERY model must be proven on it's own merits and the REASON 99.99999% of humanity believes it's a globe is because it HAS been proven repeatedly and debunked the globe model for over 2000 years now. Regardless of how you feel about that. And flat earth is impossible for dozens upon dozens of reasons that are easily seen by anyone who cares to look.
If you are truly a truth seeker and not a bandwagonist, then you'd actually learn about the history of how we know it's a globe, the observations people made hundreds and even thousands of years before any modern technology, and you'd join an astronomy club and go do some traveling to the southern hemisphere, where all flat earth models become impossible for a variety of reasons.
likewise , i can post comments of my point of view. your post says debunking flat earth, as if all flat earthers believe in the same non sense as the flat earth society. there are people spreading lies to create the confusion.
like i said , your claims are only proven by your biased consensus of believers , i was not judgement nor did i try to bash you , i made my comment , i also have that right , you chose to dialog with me , and im simply giving you a response, am i not allowed to do that too?
most of the time , globe earthers claims to a ball earth has nothing todo with the shape of it in reality. call it what you want , ice wall , continent , no one can go to antartica whats make you think you can go around it for ourselves to actually see for ourselves? controlled enviroment , its obvious i would just have to believe the claims of these men who only seek to gain income of the naive nature of human beings. I gain nothing from speaking the truth, your looking for upvotes and steem , i'll give you a support still bro.
This is the TRUE STORY of the flat earth world ... eons of time.

Ahhh, how cute that you follow the cult prescription and ignore the topic of conversation and derail it to your own spam post. What a good little cult follower you are that you have zero ability to discuss the topic at hand.
What's wrong? You seem sad and angry.
What's wrong? Why can't you address the subject at hand? Can you specify how my emotional state would be relevant to the shape of the earth or the facts at hand? Thanks in advance. Or... perhaps, you are just deflecting so you don't have to address the issues at hand because you know you are wrong and can't rebut the actual facts. Naw, flat earthers don't use cult tactics to avoid providing evidence they don't have... do they? Lmao.
So - since you appear to be a "really smart person", you tell me: Am I a flat-earther? If you can't determine that, then I have NO IDEA who you are having a conversation with.
More strawman arguments. When did I say or imply "I'm a really smart person?" Please be specific. And you put up a flat earth article that is not in context to what I was saying AT ALL. I'm simply responding to that. It makes absolutely no difference if you ARE a flat earther when I'm responding to what you put up.
If you are trying to say that your article is sarcastic, please read Poe's Law. Flat earthers are SO stupid that nothing is too preposterous for them to believe.
a) I am not a flat-earther
b) your inability to read means: 1) - you are a bot OR 2) - you are an ignoramus
c) good luck in 2nd grade
