Essay Abstract

Different physical theories have different, only partially overlapping domains. Constructing theories with a greater domain of validity in one parameter comes at the costs of shrinking the domain of validity of other parameters. This is necessarily the case because of the ontological plurality of physical reality. ‘The World’ as conceived as an entity with a unique structure does not exist. A fundamental, all comprehensive theory of physical reality does not exist, because The World does not exist.

Dear Frank,

I liked your essay. It is well written and it inspires further thought.

As for your first observation, the role of mathematics in bridging between older and newer theories, I think you miss a point here. The reason that Einstein took care to arrive at the inverse quadratic relation between gravitational force and distance, was not because he wanted to inherit from Newton’s theory but because he wanted his theory to be in line with existing observations. If the theory of general relativity would not find the inverse square law for small gravitational fields, it’s predictions simply would not match empirical data on planetary orbits, which would immediately refute the theory.

I agree with you that most physicists take the isomorphy between phyical reality and mathematics for granted. In my essay, I also arrive at a peculiar relation between physical reality and mathematics, and I might have a little to contribute to this topic as well.

With kind regards,

Paul Bastiaansen

Dear Paul,

Thanks for your interesting comment.

Yes, I think we agree that new physical theories ( e.g. GR) must retain mathematical structures from older, superseded theoies ( Newtonian gravity), albeit in a different setting ( for example differential geometry). The reason is that the older theory already captured valid empirical relation within a limited domain.

It is precisely this transfer of information about functional dependences from older, limited theories to more comprehensive theories which makes mathematics such an effective tool for physics. This process, the transfer of information between 'generations' of theories is akin to the passing on of genetic information from parents to offspring in phylogenetic biological evolution.

My main main thesis is that there does not exist a single theory comprising all physical phenomena. Observe that any one biological species is adapted to a specific environment and that the genetic material of this species contains information about this special environment. However, it does not exists a biological species which would be adapted to all possible environments. Analogously physical theories are 'adopted' to there specific ' environment ', i.e. there domain of validity.

I further maintain that it does not make sense to speak of the 'The World' as a whole, unique structure. Rather physical reality should be conceived as a network of diverse, local ' environments.

Dear Frank,

You're right.

"Different physical theories have different, only partially overlapping domains."

But this does not apply to the Philosophy of Nature. For example, the first and best TOE (Bošković's Philosophy of Nature…) covers all domains of forces. That's why it anticipated many later discoveries.

With best wishes,

Branko

Dear Frank Pohlmann

According to the principle of the identity of space and matter of Descartes, space is matter that moves. When Copernicus began to assert that the Earth revolves around the Sun, he had, according to Descarts, was obliged to add that along with the Earth around the Sun, the entire circumsolar space rotates. Space is what the whole world is built of. Space is the source of information. Look at my page, FQXi Fundamental in New Cartesian Physics by Dizhechko Boris Semyonovich Where I showed how radically the physics can change if it follows the principle of identity of space and matter of Descartes. Evaluate and leave your comment there.

Sincerely, Dizhechko Boris Semyonovich.

Dear Frank

If you are looking for another essay to read and rate in the final days of the contest, will you consider mine please? I read all essays from those who comment on my page, and if I cant rate an essay highly, then I don’t rate them at all. Infact I haven’t issued a rating lower that ten. So you have nothing to lose by having me read your essay, and everything to...

"But that does not mean that we should ascribe a unique, fundamental structure to physical reality. On the contrary, we should conceive of reality has having a multitude of irreducible different structures, none more fundamental than the other. Physical theories describe these structures in terms of different irreducible concepts (e.g. Hilbert spaces, differential geometry, etc), none of these...
