We know at least three different worlds. These worlds differ in the number of dimensions they are moving in.

There is the 1-dimensional world of calculating, of mathematics. It always uses and combines numbers, which all can be symbolized by a line of a certain length.

Then there is our 3-dimensional physical world of bodies and energies - it exists on the timeline always only in one moment, in the moment, which we call "now".

But in our mind the world is existing at least 4-dimensional. That means, we not only see and realize the "now-moment" in which our body is existing, we can remember past times and we can imagine future or fantastic times. And our feelings are connected with our remembering or with planning and hoping for a imagined future. So our feeling needs the 4-dimensional mind.

A calculating robot is constructed with 3-dimensional materials, and it is steering 3-dimensional materials. Will that robot be it able to see the world like a living mind does see the world? The first spontaneous answer may be: yes. But is it really so? Or is there a fundamental difference? This is the question the book deals about.

Maria Cura was born in 1956, studied cultural studies in Munich, but was from childhood on also interested in science like mathematics, physics, astronomy and biology. She worked in various professions and she is the mother of two grown up children.
A friend once called her a "realistic idealist".
