Measure Earth's circumference with a stick. पृथ्वी नापें सिर्फ एक छड़ी से ! in Hindi by Dear Master

In this digital era, we (humans) have many satellites, machines and space programs to know more about our mother earth and about universe, but in 276 BC, there was a man called Eratosthenes, who was managed to calculate Earth's circumference at that old era, only using a stick and some math calculations. Isn't is amazing?

Here, in this video, we are using Eratosthenes's method with little bit changes and we will measure / calculate our Earth's Circumference / perimeter.
