Happy 100th birthday, General Relativity!

"La Madre Terra" by Pietro Cascella, made for ICRANet. You can see Einstein's equation, which he translated into the metaphor "marble = wood". My guess is that it symbolizes Einstein's idea that everything (matter, life, not just the earth) emerges from the perfect geometry of spacetime. I took this photo at the Marco Besso Foundation exhibition in Rome, during the XIV-th Marcel Grossman conference.
