Speed of Light

We all know Speed of Light is 3 lakh km/sec in our School and college books it also says the speed of light was calculated by the scientists in the West.

In fact the ancient indians has calculated it centuries before it was mentioned in a slokha of Sayanacharya
it is as stated

Here in the Slokha the words Yojana and Nimesha are the units of Distance and Time of Ancient times

The Yojana=9 miles and Nimesha=0.21333 Seconds

Underlined text is number 2202

2202 X 9 = 19818

1 nimesha = 0.21333 seconds

1/2 nimesha = 0.10665 seconds

Speed=Distance / Time =19818/0.10665=185822 miles/second=299044 km/s

The Method to find Square root was mentioned in the book called Aryabhatiyam written by the famous indian astronomer and a mathematician Aryabhatta.
