I am enough of an artist to draw freely upon my imagination. Imagination is more important than knowledge. Knowledge is limited. Imagination encircles the world. The only truly valuable scientific tools are imagination and intuition. Whenever I felt that I had come to the end of the road in my work, I would intuitively take refuge in music. My violin was especially useful while working on the General Theory of Relativity. Often I would play late at night, improvising melodies while pondering complex problems. Then, suddenly, like magic in the middle of playing, I would announce, I’ve got it! As if by inspiration, the answer would come in the midst of music.
