Montreal Biosphere Montreal Biosphere The Biosphere (French: "La Biosphère de Montréal") is a museum dedicated to the environment. It is located at Parc Jean-Drapeau, on Saint Helen's Island in the former pavilion of the United States for the 1967 World Fair, Expo 67 in Montreal, Quebec, Canada. The museum's geodesic dome was designed by Buckminster Fuller. The architect of this geodesic dome was Buckminster Fuller. The building originally formed an enclosed structure of steel and acrylic cells, in diameter and high. It is a Class 1 (icosahedral, as differentiated from Class 2 domes, which are dodecahedral, and Class 3 ones, which are
Solving the geodesic equations Solving the geodesic equations Solving the geodesic equations is a procedure used in mathematics, particularly Riemannian geometry, and in physics, particularly in general relativity, that results in obtaining geodesics. Physically, these represent the paths of (usually ideal) particles with no proper acceleration, their motion satisfying the geodesic equations. Because the particles are subject to no proper acceleration, the geodesics generally represent the straightest path between two points in a curved spacetime. On an "n"-dimensional Riemannian manifold formula_1, the geodesic equation written in a coordinate chart with coordinates formula_2 is: where the coordinates "x"("s") are regarded as the coordinates of a
