DESCARTES. Cogito ergo sum. I’m a point in the dark. Yesterday already I was a point, I remember, it’s still shinning in my memory. What will I be tomorrow?
EUCLID. One day, light will finish. I don’t know anything except my life. It has only one dimension. It is a segment. My birth, my death are its limits.
GAUSS. Why Euclid? We can use other rules.
NEWTON. Light is colors.
VON KOCH. Life is a continuous curve without tangents.
