When I lived in Dusseldorf, I used to get up early and go to work in Essen.
Sometimes I would be waiting for the tram looking at the Oberkasseler Brücke over the Rhine when the sun was rising and the scent of linden flowers filled the air.
But the sun was not rising. THE EARTH WAS TURNING!
Everyday I would try to change my false perception of the sun rising so that I could perceive the Earth turning instead. That is what this picture is about. The sun is the fixed point and all things on the surface of the Earth are rolling towards it.
Once the feeling of the Earth turning was achieved I tried to keep that rotating feeling as the U-Bahn went underground into the Earth. As the tram moved forward, I could feel the Earth turning without being able to see the sun, if I really concentrated on it.
We still believe in illusions which belong to ancient times. We talk of "sunrise" and "sunset" as if we lived on a flat Earth and we were the centre of the universe. Human perceptions do not keep up with rational and scientific knowledge. We do not adjust our thinking to the knowledge resources which are generally available and which are common knowledge to most people, even to those with minimal education.
