This paper proposes one of the first scalable methods for estimating the number of clusters of solutions of graph coloring problems using a belief propagation like algorithm.

An excerpt from a novel that explores the tensions of racial passing. Set in Chicago, Passing examines the diverging lives and chance reunions of two light-skinned women.

This page gives a brief explanation of the Laplace limit, the value of "e" "for which Laplace's formula for solving Kepler's equation begins diverging."

This page states the Ratio Test for convergent or divergent series, sometimes called the Cauchy Ratio Test or the d'Alembert Ratio Test. Brief but informational.

The words noise, nausea, and naval all stem from the same Latin root. Jessica Oreck divulges how their spellings and meanings diverged from the original naus. [2:02]

This resource gives an introduction to the theory of plate tectonics. It also has animations of four types of plate boundary interactions (convergent, divergent, transforming, collisional).

Provides a summary of tests for series that includes the test, series, converges, sum of remainder, and diverges for nth Term, Geometric Series, Telescoping Series, p-Series, Alternating Series, Integral, Root, Ratio, Direct Comparison,...

Gamers will test their knowledge of plate tectonics with this interactive. Know your divergent plate boundaries, hot spots, trenches, lithosphere, and other trivial facts of plate tectonics.

A course lecture on how the Earth's geological features have evolved through the movements of tectonic plates. Explains the different types of plate boundaries and how they manifest in geological formations. Also describes the structure...
