Connes is doing new f.o.m., inspired from noncommutative geometry, at least
in the following two points:
(A) Unification between continuous variable and discrete variable as
self-adjoint operators on the (unique) separable Hilbert space.
(B) Definition of (noncommutative) infinitesimals as compact self-adjoint
operators on the separable Hilbert space (a particular case of a variable).

Connes' argument for accepting (A) in mathematics rather than the
traditional approach is as follows:
A real variable is a map f: X --> R (from a set X to the real line). This

Kind Regards,
