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
harmony which has been imposed on it by God
and which He revealed to us
in the language of mathematics.
