The Formal Theorem

layers of integers

Analytical Intuition.

Continued Fractions are the Best Rational Approximations. Finding the closest fraction to an irrational (like pi or e). Geometric lattice points closest to a diagonal line.
CAUTION

Institutional Warning.

Finite fractions are rational; periodic ones are quadratic irrationals. e has a beautiful infinite pattern.
