Henry Classification System "Finger Prints" in which he described his classification system that include three main fingerprint patterns - loops, whorls and arches. At the time, the alternative to fingerprints was Bertillonage, also known as Anthropometry. Developed by Alphonse Bertillon in 1879, Bertillonage consists of a meticulous method of measuring body parts for the use of identifying criminals. In 1892, the British Indian police force adopted Anthropometry. Two years later, Sir Edward Henry, Inspector General of the Bengal Police in India became interested in the use of fingerprints for the use of criminal identification. Influenced by Galton's "Finger Prints", the men corresponded regularly
Isotopy of loops they are equivalent from "geometric point of view". The dictionary between algebraic and geometric concepts is as follows Isotopy of loops In the mathematical field of abstract algebra, isotopy is an equivalence relation used to classify the algebraic notion of loop. Isotopy for loops and quasigroups was introduced by , based on his slightly earlier definition of isotopy for algebras, which was in turn inspired by work of Steenrod. Each quasigroup is isotopic to a loop. Let formula_1 and formula_2 be quasigroups. A quasigroup homotopy from "Q" to "P" is a triple of maps from "Q" to "P" such that
