Geometry has two great treasures;
one is the Theorem of Pythagoras;
the other, the division of a line
into extreme and mean ratio.
The first  
we may compare to a measure of gold;
the second  
we may name a precious jewel.

Science is the process of
thinking God's thoughts after Him.

The chief aim of all investigations
of the external world should be
to discover  
the rational order and harmony
which has been imposed on it by God
and which He revealed to us
in the language of mathematics.

and the New Astronomy
