Physics is essentially an intuitive and concrete science. Mathematics is only a means for expressing the laws that govern phenomena.
Albert EinsteinThe truth of a theory can never be proven, for one never knows if future experience will contradict its conclusions.
Albert EinsteinWhen we first got married, we made a pact. It was this: In our life together, it was decided I would make all of the big decisions and my wife would make all of the little decisions. For fifty years, we have held true to that agreement. I believe that is the reason for the success in our marriage. However, the strange thing is that in fifty years, there hasn’t been one big decision.
