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 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.

comment Why must the particles of an ideal gas be point-like?
I wonder: What observable difference does it make whether the particles are point-like or not - assumed they are "hard balls"?

@user3376924. To be honest: I am not sure. It has been only an impression. (Among others I found this source: sklogwiki.org/SklogWiki/index.php/Hard_sphere_model but could not delve deeper into it.)

comment Lennard-Jones induced pseudo-molecules
But when we think - theoretically and counterfactually - of a Lennard-Jones-like potential with a really deep and really narrow potential well, from which really stable clusters arise? (To make things clear: I am happy with handwaving arguments for the impossibility of such situations.)
