Prithvi Gol Hone Ki Pehli Soch
Prithvi ki golai ka gyaan sabse pehle kaise aur kisne prapt kiya, ye ek rochak kahani hai. Is gyaan ka vikas samay ke sath-sath hua, aur kai prachin sabhyataon ne is par vichar kiya.
Prachin Sabhyataon ka Yogdaan
- Bhaarat (Bharat): Aryabhata, ek prachin Indian ganitgyani, ne 5vi sadi ke aas-paas Prithvi ki golai ke baare mein likha. Unhone kaha ki Prithvi gol hai aur iski gati ka bhi ullekh kiya.
- Yunani Darshanik: Pythagoras (570–495 BCE) aur Aristotle (384–322 BCE) jaise darshanikon ne bhi Prithvi ki golai ka vichar kiya. Aristotle ne Prithvi ke gol hone ke pramaan diye, jaise ki chand ki chhaya aur sitaron ki dikhayi.
Gyaan ka Vikas
- Duniya ki Pehli Nakshe: Claudius Ptolemy ne 2nd sadi mein ek naksha banaya jisme Prithvi ko gol dikhaaya gaya. Is nakshe ne duniya ke geographiya ko samajhne mein madad ki.
- Navin Yuga: 15vi sadi mein, Copernicus ne Prithvi ki golai aur uski surya ke ird-gird ghoomne ki soch ko aur majboot kiya. Isne vishwa ko ek naya dhrishtikon diya.
Antim Soch
Prithvi ki golai ka gyaan ek samay mein dhire-dhire vikasit hua. Is vishay par kai darshanikon aur ganitgyaniyon ka yogdaan raha, jisse aaj hum is gyaan ko samajhte hain.
