# Toby Bartels

I am Toby BARTELS (they/them).
## Personal

As far as I can tell,
I'm the only English-speaking ‘Toby Bartels’ on the Internet;
you can check my identity for yourself.
Look at some pictures of me
if you want to recognize me in real life,
or send me email to contact me.
If you're a close friend or relative,
then you may be interested in my gift list.
## Mathematics

I teach Mathematics
at Southeast Community College
(SCC)
in Lincoln NE;
if you're currently taking a class with me,
then you probably want
the web page for the course that I'm teaching now:
College Algebra
(MATH-1150-HBL41).
You might also want my virtual office hours
over Zoom
at 610-024-2876
or to send me
a Canvas message.
I first taught and tutored at SCC in 2006,
and I now teach there full-time.
I also taught Algebra
at the University of La Verne
in California
in 2008.
Before all that, I taught Discrete Mathematics
in the summers
at the University of California, Riverside.
You may want to look at the web pages
for these and other earlier courses.
Or see
the most up-to-date version of my Calculus notes.

In 2006, I got my PhD
working under John Baez.
My doctoral dissertation
is Higher Gauge Theory I: 2-Bundles,
which categorifies the concept of fibre bundle
to the (algebraically) higher-dimensional concept of 2-bundle
and proves the equivalence (in appropriate cases) of 2-bundles and gerbes.
This was part of John's work
on higher
gauge theory.

I also have
some short expository notes
on other subjects in mathematics and mathematical physics.
In a different style, there's Oz's crib sheet.
Most of my mathematical work
that has been published (made available to the public)
is unreviewed collaborative work
on the nLab (*n*-Category Lab),
a specialist wiki for higher-dimensional mathematics.

## Activism

This part of my life is pretty much stalled,
other than making performative comments on social media sites.
However, in the days before such sites,
I once impulsively copied
the Statement of
Murder Victims' Families for Reconciliation
on the Execution of Timothy McVeigh.
Now my website seems to be the only place where it can be reliably found,
so I keep it up.
While I support their position, I'm not affiliated with the organization.

I also used to be
heavily involved with
the Common Root Mutual Aid Center,
so check them out.
