Welcome

 Mathematics can help you grasp the world!

Over 2200 years ago a Greek scholar and librarian named 
Eratosthenes accurately calculated the circumference of the earth.  He 
accomplished this with measurements from a gnomon (a stick that 
casts a shadow) and some simple geometry.  Man's view of the world 
has not been the same since.
