My interests:

  • abstract structures
    (e.g. graphs, groups, polytopes, spaces, ...)

    in the course of this

  • category theory

  • model theory

  • presentations and representations
    (e.g. of abstract structures by or inside other abstract structures)

    next to this

  • philosophy
    (esp. of mathematics, science, and mind)

    especially concerned with

  • atomism
    (i.e. reductionistic or other theories referring to some kind of "atoms")

  • their refutations

comment Dimension of galaxy filaments
For a generic structure of superclusters I would assume d~3: they are somehow arranged.

comment Origins of many-particle interactions
Even though I do appreciate this specific answer, I do wonder why one always starts learning about interactions as pair interactions - that's the usual way to think about interactions - and only by accident I learn that pair interactions are only a convenient approximation. Approximation of what? And in which more general context?

Thanks, Joce. But how can those interactions be - positively - described? (You just say how the can not be described.)

comment A real gas with gravitation-like interaction
@DumpsterDoofus: You probably are right - but that's the kind of objection I am looking for! (But maybe the system is all that there is - and it cannot be cooled "from the outside"?)

I tacitly assumed the collisions with the wall of the box are also elastic, so no transfer of energy takes place.
