Mathematics/physics/necessity/Field: e.g. Laplace equation: physical equation - holds not with logical necessity - even if the mathematics 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._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number. The corresponding books are indicated on the right hand side. ((s)…): Comment by the sender of the contribution.
