Yesterday marked the 100th anniversary of the disclosure by Einstein of its General Relativity Equation. Less catchy then his e=mc2 (mc square) it is nevertheless one of the most significant insight in the structure of the universe.
Although it is somewhat esoteric in terms of our (lay people) capability of understanding it (and even physicists are still working on understanding how to make the match between General Relativity and Quantum Mechanics) we are using it every day as we drive our cars with the assistance of GPS. The pinpointing of our location has to take into account the tiny curvature of space time.
Our future is rooted in the past. Nice to remember it sometimes.
