The Oregon Convention Center features some wonderful public art and one of my favorites is Principia, the world’s largest Foucault Pendulum. The Convention Center’s art guide says this about the piece “The dramatic Foucalt pendulum hangs from the north tower and swings across a 40’ halo of suspended gilded rays. Directly below, a 40’ blue terrazzo floor is inlaid with brass rings and colored stone “planets” depicting a fantasy solar system.”. It is a beautiful creation and I suspect that many people don’t notice it gently swaying over head nor the terrazzo floor underfoot.
Very short videos can be seen here and here. A brief explanation of the history and importance of the Foucault Pendulum can be found on Wikipedia. A fun way to see the art is to go to the convention center’s 360 page and look at the Exhibit Space, Pre-conference Halls A & B.
