The Silver Thaw
A silent beam from a distant sun, Touching the crust where the frost has spun. Awakening crystals, ancient and deep, Stirring the moon from its crystalline sleep. A warmth that is phantom, a light without heat, Making the pulse of the permafrost beat.

Counting Without Counting
Burnside's Lemma is a clever tool used to count the number of distinct patterns in a set when some patterns are actually just rotations or flips of others. Instead of manually checking every possibility, it allows you to use the symmetry of an object to find the answer. It is a fundamental building block in the study of group theory and combinatorics.
