ASM Headquarters and Geodesic Dome the American Society for Metals in September 1959, the geodesic dome was built on a 100-acre parcel donated by William Hunt Eisenman (1886–1958), a charter member of the American Society of Metals and its secretary for nearly four decades. In 1961, ASM purchased William Hunt Eisenman's Sunnimoor Farm and 400-acres of land adjacent to the ASM campus. The complex was designed by John Terrence Kelly, a native of Elyria, Ohio. There are differing opinions on R. Buckminster Fuller's role in the design of ASM's dome. While Fuller was a founding partner of Synergetics, Inc. and a patent holder for geodesic
Geodesic deviation "geodesic". The "geodesic deviation equation" relates the Riemann curvature tensor to the relative acceleration of two neighboring geodesics. In differential geometry, the geodesic deviation equation is more commonly known as the Jacobi equation. To quantify geodesic deviation, one begins by setting up a family of closely spaced geodesics indexed by a continuous variable "s" and parametrized by an affine parameter τ. That is, for each fixed "s", the curve swept out by γ(τ) as τ varies is a geodesic. When considering the geodesic of a massive object, it is often convenient to choose τ to be the object's proper time.
