A University of Colorado mathematician solved the mathematical model behind the Eiffel Tower's shape by studying Gustave Eiffel's historical writings about wind resistance. Patrick Weidman discovered that Eiffel designed the tower by balancing wind pressure with internal tension, using geometric principles rather than a single overarching equation.
Eiffel and Lua, two programming languages from different domains, share surprising design philosophies despite their surface differences. Both were created by small, visionary teams outside corporate structures and emphasize readability, minimalism, and careful design choices over feature accumulation. They exhibit syntactic similarities rooted in the Algol-Pascal tradition and share convictions about what languages should exclude.
