Lorraine Ford Hi, You d like a lot the book of Bob Coecke , quantum in pictures, I discussed with him on facebook and he beleives strongly that the relations are important between the systems. His book is more than relevant you know. He has sent me it in Finland. This Relational quantum mechanics (RQM) is a relevant idea for the interpretations of our QM because it tells mainly that the relation between the observer and the system give this relation of the quantum state. So the categories and numbers are important ..... I see many convergences with the ideas of Wheeler about the quantum informations. It seems evident that the most important is the relations between the objects , that could permit to better understand these quantum objects and their nature and philosophical origin in trying different mathematical partitions. If this QM is a theory about the physial description of physial systems, so these relations to others systems seem essential for a better understanding of this world.
What I find important is that different observers give different analysis about the exact same system, it is mainly about the states and is essential because is relative to the observer. It is about the state vector, that is why there are relevances with the geometrial algebras, It is what I try to to with the spherical geometrical topological algebras, the tool that I have invented , and in trying to consider the degrees of freedom in the observations and in trying to apply the quantum , cosmological and our dimension scales. This observer dependence now becomes relevant about the consciousness and so these observations. So what is the rule of our consciousness and our observations philosophically speaking about the states of systems.....
The measurements and the interpretations of QM so become philosophially relevant because give roads inside and beyond this relativity at my opinion. That gives paradox lie the EPR for example in cosmology but can be applied for the quantum scale or our scale, beause it is mainly about the observations and the observed objects and how we must consider this relativity. Everett has well developped these things. The importance so of categoroes, numbers and PROBABILITIES become more than essential . There are probably many experiments to do about these general ideas and reasonings giving a better understanding about the interpretations of this QM, That tells us even that our QM is a not complete theory simply and that we must add deeper fields, particles and philosophies.
So Rovelli is right about the fact that we could modify our views of this world that we observe. That is why this relativity maybe imply confusions about the real states and also we have probably deeper physical parameters to superimpose. That is why the problem of hidden variables is moe complex that we can imagine because beyond this relativity , so Rovelli is right about the actual relativitic observations but maybe make a small error in telling that we have no hidden variables because simply they are beyond these observations. It gives even deep questions about the informations and their primary essence and even about what are the foundamental objects in going farer than this relativity, that is why I consider spheres in a fluidity for the 3 main systems , thre photons, DE and DM, and not strings in 1d in this relativistic spacetime connected at this quantum and cosnmologial scales, And after with the geometrical algebras like the E8 of lie they consider the scalars, vectors, tensors and extradiemnsions to explain this reality and its observations, this reasoning imply several philosophical road about a god or a mathematical accident but the problem is not there, the problem is about the foundamental objects and the cause of this reality .
My interpretation so in my theory of spherisation , an optimisation evolution of the universe is a kind of mix with the relational QM, the Copenaghian one and the Hidden variables not relativistic and the aim with the spherical geometrical topologial algebras and these spheres like foundmamental objects is to rank the categories and dimensions with the observations and consciousness with kinds of bridges but not easy . I try with the 3 main cosmologial free systems and in converging for the ordinary matter like a result of 3 others merging with these bridges but complex with these salars, tensors , vectors,
