Any objective type of physics has to keep the observer ouside.
Oddly enough, this goal can only be reached when the
observer is explicitly included in a larger image
which will only then be independent of the observer.
In doing so, one sees that the world is always
being defined merely on the interface between
the observer and the rest of the world.
Since this interface is by definition inaccessible,
there seems to be no solution to our problem.
We cannot step out of our world to assume the role of a
super-observer, therefore we cannot understand the world.
Most unexpectedly, there is probably a tiny loophole;
"model worlds" can be constructed which imply an
explicit internal (microscopically described) observer.

INTRODUCTION TO THE SYMPOSIUM

During the symposium, endophysics, an advanced branch of natural sciences, is introduced. Only if one is outside a nontrivial universe it is possible to describe the latter completely - for instance when you have this universe in the computer. In general, the laws which apply if you are an inside part yourself are different (endophysics is different from exophysics). In mathematics, Gödel's proof is the first example. In physics, it is necessary to have explicit observers included in the model world. Brain models can be seen as an example for this. Macroscopic brain models, however, are non-explicit by nature. Therefore, an explicit microscopic universe is introduced in terms of a classic, one-dimensional Hamiltonian function in which "formal brains" can exist as explicit dissipative structures in the sense of Prigogine. Relevant endophysics is still largely unknown. As a first step, the implications arising from the fact that the observer contains indistinguishable particles (Gibbs symmetry) are being considered. Norman Campbell's postulate - a swift vacillation of time's axis on the micro-level - turns out to be an implicaton with Nelson's postulate and thus also the Schrödinger equation following as corollaries. Therefore, a "non-local" interface can be created by a local theory. Microscopic observer properties can "bubble up" to influence the macroscopic spatio-temporal appearance of the model world. Physics becomes dependent on brain theory.
