I sure had a head cold that day.

Studying medical imaging that way was kind
of totem-ish, like, maybe if I study medical
imaging today, then sympathetic magic will
help kick my cold and diseases begin with 'C'.
Seemed helped, .... Yet, that's humor for you.


About "points-in-a-line", the classical notion
is "beads-on-a-string", here as with regards
to "the course-of-passage", that ordinals have
a course of passage through ordinals, and that
line-drawing, has a course of passage through
points.

Divising a specialization of "in", "on", and
"about", the line, its points, helps to characterize
that line-drawing makes points "in" a line, that
zooming in via field operations points to, that
it establishes a vector field with all the arrows
reducing in region until their heads touch and
that they point-to, a point, "on" a line, then
as with regards to a super-fine comb each tooth
"about" the line.

DICOM is a family of standards in medical imaging
data and metadata, sort of like JPEG for doctors.
See also "HL7". The JPEG2000 is pretty great,
I studied data formats a lot.


Chaos theory and its terms is sort of folded into
"dynamical modeling", as with regards to for example
"limit cycles" for "attractors", then as with regards
to for example Nayfeh's tome on non-linear oscillations.


Anyways, here line-reals and signal-reals "exist"
next to field-reals, at least three models of
continuous domains, each with their own definition
of "continuous", all satisfying the same properties
of extent, density, completeness, and measure, from
which can be established most all their combined
character, as "real-valued".
