When I was a girl, I dreamt of standing in a room looking at a girl who was and was not myself, who stood looking at another girl, who was and was not myself. My mother took this for a nightmare. I saw it as the beginning of a career in physics.”

-Rosalind Lutece, Viewing the Infinite: August the 10th, 1890
