Expo 67 pavilions Expo 67 pavilions The Expo 67 International and Universal Exposition featured 90 pavilions representing Man and His World, on a theme derived from , written by the famous French pilot Antoine de Saint-Exupéry. The exposition displayed many nations, corporations, industries, technologies, social themes, religions and designs, including the US pavilion, a geodesic dome designed by Buckminster Fuller. Expo 67 also featured Habitat 67, an urban modular housing complex designed by architect Moshe Safdie, whose units were purchased by private Montrealers after the fair was concluded, and is still occupied today. The most popular display of the exposition was the soaring
Solving the geodesic equations curve γ("s") in formula_1 and formula_5 are the Christoffel symbols. The Christoffel symbols are functions of the metric and are given by: where the comma indicates a partial derivative with respect to the coordinates: As the manifold has dimension formula_8, the geodesic equations are a system of formula_8 ordinary differential equations for the formula_8 coordinate variables. Thus, allied with initial conditions, the system can, according to the Picard–Lindelöf theorem, be solved. One can also use a Lagrangian approach to the problem: defining and applying the Euler–Lagrange equation. As the laws of physics can be written in any coordinate system, it
