Steve Kieffer
Currently on sabbatical, tinkering with projects for teaching and sharing math.
Recent Work
These days, besides travelling, I'm mostly working on some projects organized under a little
nonprofit I started, called Royalroad Math.
The first such project was Proofscape,
a collaborative visual library of mathematics.
Other, related math projects are on the horizon, and I'll try to post some materials about them as
soon as I can!
I also recently contributed a new library to the
Adaptagrams project, a C++ library for
constraintbased network layout. Adaptagrams is used in many projects, including the
Dunnart layout editor:
Camper Van Conversions
This is a new area for me. Actually I've just done the one conversion, which
was so I could travel on my sabbatical.
Here's how I did it.
Improvisational Piano
I've been playing blues and jazz piano for many years. I usually don't record
anything I play, but I did record one session a few years ago. Here's a sample:
and here's
the whole session.

Miscellaneous
Do you find anything cumbersome about TeX syntax?
For example,
If instead of this... 
you'd prefer to type this... 
a_0, a_1, \ldots, a_{n1} 
a0, a1, ddd, an1 
\alpha, \beta, \gamma, ... 
alpha, beta, gamma, ... 
\mathfrak{p} \in \mathbb{Z} 
frp in bbZ 
\frac{2}{3} 
frac 2 over 3; 
\left x \right 
abs x; 
f^{(n)} 
f supp n; 
f^{1} 
f inv 
\sum_{n=0}^\infty a_n 
sum over n from 0 to infty; an 
...then use VerTeX.
Installation note: The script expects python to be at
/usr/bin/python. If it's not, just change the first line accordingly.
I have done no testing on Windows; try at your own
risk. Runs fine on all Macs and Linux machines tried so far.
Perpetual Calendars
Cryptic crosswords
Cryptic crosswords put an extra twist on ordinary cruciverbology, each
clue featuring a literal definition at one end, and word play at the
other, and you don't know which is which.
I have Chris Mears to thank for getting me hooked on this great time
waster.
Scribblings
Nothing groundbreaking here...
