Eratosthenes (Bahasa Yunani Kuno: Ἐρατοσθένης, sekitar 276 BC[1] – sekitar 195 SM[2]) adalah seorang ahli matematik, penyair, atlet, ahli geografi, ahli astronomi, dan ahli teori muzik Yunani. Ia dilahirkan di Cyrene, Libya, dan wafat di Alexandria, Mesir.

Sumbangan utamanya ialah pengiraan panjang lilitan bumi. Nilai yang didapatinya adalah hampir 25,000 batu, tidak jauh dari nilai sekarang iaitu 24,900 batu.
Eratosthenes juga mengatakan bahawa India boleh didatangi dengan belayar ke barat (pada masa itu pelayaran ke India hanya ke arah timur).
Daripada kesamaan air pasang dan air surut di lautan Hindi dan lautan Atlantik, Eratosthenes berpendapat kedua-dua lautan itu mesti bercantum di selatan benua Afrika.


lihat video ini , bgmn dia kira panjang lilitan bumi




sains modern kata - dari data satelit , mereka kira keluar panjang lilitan bumi ,  hampir sama dgn kiraan Eratosthenes.

tahu langit tiada satelit ?  haha ... apa kebocoran cerita ini ?  lihat bawah .

Now, another way that you can tell that we’re on a sphere is to think about how there’s something called the tropics on the Earth, and the tropics are places
near the equator of the earth were sometimes the sun is overhead in the sky. This was actually something that the Greeks used, not only to prove that the Earth was round about 2000 years ago,
but they actually measured the circumference of the Earth, accurate to within just a couple percent. 2,000 years ago we’ve known that the Earth was round.There was a really brilliant Greek scientist called Eratosthenes, and Eratosthenes noticed that there was a town called Syene, and on a certain date the sun would actually shine straight down to the bottom of a well.
That meant the sun was directly overhead; you could look down a well and see the sun shining back at you.And on the very same date, farther away in the city of Alexandria, that didn’t happen. The sun was not directly overhead, it was a slight angle, and all that Eratosthenes did was he measured the difference in the angle of the sun.
It was straight overhead in Syene; in Alexandria it was a little bit less than overhead, and he rationed that that change in angle from one city to another was probably indicative of us being on a curved surface,
and you could make all kinds of measurements even between those two cities and see that the angles were different—the sun was at a different place in the sky.
Using this, he actually measured the circumference of the Earth, and he got it right 2,000 years ago.


So another really simple proof is that on any given date, at different cities and different places around the world, the sun is at different angles in the sky. That wouldn’t happen if the Earth wasn’t round.




apa yg mereka tipu kami (penipu Eratosthenes dan wanita NASA ini) ?


sudut matahari bbeza dari 2 tempat , dan sahkan hanya dapat blaku di bumi sfera ?  tak mungkin di bumi datar ?  


sekali lagi tipu org yg tiada ilmu


apa yg mereka tak beritahu kamu ? apa rahsia disimpan ?




Eratosthenes dalam kira2 matematik tidak ambil kira faktor refraction ,  


krn matahari yg dia lihat di langit bukan kedudukan matahari yg sebenar .


apparent sun - kedudukan matahari yg dilihat kita
real sun - kedudukan matahari yg sebenar ( tak tahu di mana , hanya kira dgn matematik)

Eratosthenes guna kedudukan matahari apparent ini kira panjang lilitan bumi , salah teruk , kedudukan matahari dah salah ,

jadi terhasil sudut yg salah juga ,  setiap org di tempat lain , bukan lihat matahari pada kedudukan yg sama , ia beza , sudut yg kira 2 tempat , pun salah juga .

lihat video bawah dari dr zack




jadi bolehkah kita pastikan kedudukan sebenar matahari ?  boleh , tapi mungkin salah , mungkin betul .

ia hanya guna matematik , tapi tak tahu betul ke tidak , tak dapat lihat yg kedudukan yg asal , bgmn tahu betul atau salah ? ini semua hanya andaian shj .
