We know in Bengali, upto crore.(10 to the power 7. ) In english there is no terminology for 10 *1000. And 1lac*10. In Bengali we are familiar with AJUTA. NIJUTA.
Here I am showing the Vedic Source of terminology for up to 10 to the power 17.
I think in modern science it is very useful in ASTRONMOY AND QUANTUM PHYSICS.
Why our Ancestors founded this terms? This is also for Astronomy, space research and atomic research of that time. Now think and feel their depth of knowledge. Which is still invincible.
