San Diego International Airport, California, USA

This airport elevator artwork is inspired by Einstein’s famous Elevator Thought Experiment where he arrived at his Equivalence Principle of ACCELERATION = GRAVITY, and later developed into his Special Relativity Theory. 

The artist designed this airport elevator into a walk-in weighting scale with a cab floor meter, so that riders can couple their subjective bodily sensation of upward acceleration while witnessing their weight gain, deceleration their weight lost, and inertia their weight stabilized.
