ring of fire [jatp]

While leisurely biking in Paris the previous (grey) weekend, my wife and I stopped by the entrance to the Jardin des Plantes, in front of a (grey) renovated building of l’Institut de physique du globe, where we both attended (maths) lectures in the 1980’s. I had noticed the renovation years ago and in particular the red neon fractured line going over the faces of the building, but never considered it had a specific meaning.In fact, the apparent random walk has nothing random as it reproduces the Ring of Fire, a Fuller projection of the continuum of volcanoes that ring the Pacific Ocean. (This sculpture was created by Angela Detanico et Rafael Lain.)
