41Fractography — is the study of fracture surfaces of materials. Fractographic methods are routinely used to determine the cause of failure in engineering structures, especially in product failure and the practice of forensic engineering or failure analysis. In… …
42Atkin-Lehner theory — In mathematics, the Atkin Lehner theory is an algebraic part of the theory of modular forms, in which the concept of newform is defined. A newform is a cusp form new at a given level N , where the levels refer to the nested subgroups: Gamma;( N… …
432π theorem — In mathematics, the 2π theorem of Gromov and Thurston states a sufficient condition for Dehn filling on a cusped hyperbolic 3 manifold to result in a negatively curved 3 manifold. Let M be a cusped hyperbolic 3 manifold. Disjoint horoball… …

46Fusion power — The Sun is a natural fusion reactor. Fusion power is the power generated by nuclear fusion processes. In fusion reactions two light atomic nuclei fuse together to form a heavier nucleus (in contrast with fission power). In doing so they release a …
47Modular curve — In number theory and algebraic geometry, a modular curve Y(Γ) is a Riemann surface, or the corresponding algebraic curve, constructed as a quotient of the complex upper half plane H by the action of a congruence subgroup Γ of the modular group of …
