"Shutting up like a Telescope": Lewis Carroll's "Curious Condensation Method for Evaluating Determinants"
Rice, Adrian; Torrence, Eve
College Mathematics Journal, v38 n2 p85-95 Mar 2007
Charles Dodgson (Lewis Carroll) discovered a "curious" method for computing determinants. It is an iterative process that uses determinants of 2 x 2 submatrices of a matrix to obtain a smaller matrix. When the process ends, the result is the determinant of the original matrix. This article discusses both the algorithm and what may have led Dodgson to it.
