I like the style promoted by The Gregg Reference Manual because it is simple and straightforward. Regarding hyphenated words, Gregg says, In a heading or title, capitalize all the elements except articles, short prepositions, and short conjunctions.. In Gregg, short means fewer than four letters. Following the Gregg way, both parts of Tune-Up are capitalized because up is an adverb in that expression.
A geodesic dome is a sphere-like structure composed of a complex network of triangles. The triangles create a self-bracing framework that gives structural strength while using a minimum of material.
A geodesic sphere and its dual. The mathematical object chord of the geodesic sphere corresponds to the structural strut of the physical geodesic dome. A chord is a (straight) line segment joining two points on a curve.For simple geodesic domes, curves follow the surface of a sphere circumscribing a regular polyhedron with triangular faces (tetrahedron, icosahedron, or octahedron).he first dome that could be called geodesic in every respect was designed after World War I by Walther Bauersfeld, chief engineer of the Carl Zeiss optical company, for a planetarium to house his planetarium projector.
