Mathematics / Physics / necessity / Field: e.g. Laplace equation: physical equation - holds not with logical necessity - even if the math is valid. - Solution: separation in a purely mathematical and a purely physical part - the equation does not have to be preceded by a necessity operator - but probably a by chance operator. - Problem: that still does not allow to preserve Platonic physics.
