All I need are base geographic datasets of India.
Boundary shapefiles with international borders, and maybe state borders and ideally, place names.
I've been searching and searching and I can't seem to find anything except a really low resolution set of boundary shapefiles.

Use Coulomb's law to determine the magnitude and direction. Q=7.0 C and from +Q to point A is 10.0cm from point A to point B is 5.0 cm and from point B to +Q is 5.0 cm. The height from point A to +Q is 5.0 cm.

I thought this even before we discovered that living creatures in the deepest part of the ocean can live beyond boiling point.
We we're always told that creatures can't live beyond boiling point and now we know the truth.
I don't believe there are any limits as well as time through space is unlimited.
So know really think about it.
As hot as the sun is .......could there be creatures that are built to handle that atmosphere?
Just a thought.

The earth was flat but now it's not
The moon was cheese but now it's not
I think you understand the point I'm trying to get across.
