Export formats: Is there an in-house Emacs final format?

Export formats: Is there an in-house Emacs final format?

I'm a beginner, and I'm trying to imagine how I'd use org mode to create a
sort of running conversation with myself. That is, I'd like to do a form of
journaling where I could make notes to myself, which would include the
usual text as outlne-hierarchy, hyperlinks too, but also babel code chunks,
as well as any sort of mathematical formulae I might want to include. It's
this last requirement that seems to be the hardest. As far as I can tell,
the readability of my raw org file would go out the window when I started
trying to put in math formulae. As I understand, you basically do raw Tex
markup for math stuff -- and you can only see the results when you export
to something external to Emacs like html for a browser or PDF for a PDF
viewer. Is this correct?

And for my title question, is there a native "in-house" i.e., the final
product is viewable in Emacs, export that would be rich enough (text,
images, and math symbols)? Besides the embedding of a PDF viewer in a
buffer trick, Emacs seems to have only Info. Does Info allow images and
fairly normal-looking math symbols? Or is "final product" always an
off-site, extra-Emacs business?

Hi Lawrence,

emacs (in a window, not in the terminal) allows display of images. 
C-c C-x C-v will display your LaTeX equations as graphics in the 
buffer. No need for other software.

You could also look at UTF-8 mode (C-c C-x \) to display \alpha and 
x_y as their respective greek and subscript sympbols, for example.

And finally you could look into various pretty-symbol modes so your 
text and even python code looks more analog. With pretty symbols 
np.sum(sqrt(x)) looks like the greek sum and the sqrt symbols. A 
cheap ASCII view would be: Ev(x)

   -k.

As I understand, "C-c C-x C-v" (org-toggle-inline-images) will only show
images inline, not latex fragments (equations). For latex you want "C-c
C-x C-v" (org-preview-latex-fragment).

I have a folder with org files as my personal "knowledge archive" and I
use both org-toggle-inline-images and
org-preview-latex-fragment. Org-mode is indeed very nice for this
"conversation with myself" use case. Obviously you still get better
(prettier) results if you export the org file, but I rarely need to do
that.

I think the second should be C-c C-x C-l?
