Today i'm skimming through sections on pullbacks and pushforwards without much
understanding; I think i've gone pretty far down the math path for now and need
to push through to some physical problems. I can return later if I need to?
It looks like ultimately it will be a good example of the functional approach,
but stumbles before strides.
<p />
To define: Cartan, Christoffel,
<p />
I like the list of thing which are important enough to be refered to with a
"the-" prefix in scheme:
<pre style="margin:20px; border-left: solid grey 3px; background-color:lightgrey
;padding:5px;width:750px;">
the-cons-table the-empty-stream the-environment the-environment?
the-ether the-null-symbol the-real-line
</pre>
What components of the entire operating system are unique/important enough to
be refered to this way? The only "a-" is a-reduce, which while technically
"a" thing, doesn't refer to just any old reduce. This makes sense.
<p />
Whew, finally got through the end of the differential geometry memo, at least
skimming through it. Looks like there's plenty of work still to be done! Of
course i'm sure a lot of it is in will's calculus additions, i'll have to
look through that next.
