Legend has it that Albert Einstein was very fond of the violin and possessed a certain level of expertise. There was once a critic, not particularly knowledgeable about physics, who, after listening to his performance, remarked to others, "A very excellent performance, but I don't think it matches his world-renowned reputation; many people play as well as he does." As a performer, although Einstein's achievements in music couldn't compare to his accomplishments in physics, he was still regarded as "excellent."
Moreover, Einstein had another small habit. Occasionally, while in thought, he would hold the violin and unconsciously rub the strings with the bow. In such situations, he considered the sounds he produced to be tuneless and unlistenable. Yet, this remained a long-standing habit.
Four hundred years later, another person with a similar perspective reminisced about a story he heard in his youth.
