I'm guessing all
we can know for sure
is that when the
time comes, all
will be different
from what we had
expected, predicted.
Yes, it will be
different from
what we had imagined
when we get there,
when we get to the time,
when time comes
to get us.

A Fabulous Free Source for Learning Linear Algebra
College textbooks have become notoriously, outrageously expensive, and publishers often play a game of bringing out new editions that have relatively little new material but just enough new material that a student can't really get by with an older, much less expensive, used copy.
Well, if you're taking or teaching linear algebra or are otherwise interested in the subject, there are some great free sources for you, thanks to my colleague at the University of Puget Sound, Rob Beezer, Professor Mathematics. Rob and I share an interest in the possibilities of online publishing, print-on-demand, and so on--he from the math world, I from the poetry and fiction and teaching creative writing worlds.
So check out Rob's site: http://linear.ups.edu/
The first paragraph you'll see there is . . .
A First Course in Linear Algebra is an introductory textbook designed for university sophomores and juniors. Typically such a student will have taken calculus, but this is not a prerequisite. The book begins with systems of linear equations, then covers matrix algebra, before taking up finite-dimensional vector spaces in full generality. The final chapter covers matrix representations of linear transformations, through diagonalization, change of basis and Jordan canonical form. Along the way, determinants and eigenvalues get fair time. There is a comprehensive online edition and PDF versions are available to download for printing or on-screen viewing. Physical copies may be purchased from the print-on-demand service at Lulu.com.
So, if you want a "hard" copy you MAY buy one, but you don't have to. You may download a pdf or read the book online. And here the address for the online version:
http://linear.ups.edu/html/fcla.html
And here is a link to "Knowls," which enhances your browsing experience for such math-related things.
Sadly, although Rob and I share an interest in the Creative Commons, free or near-free textbooks, print-on-demand, and so on, linear algebra to me looks mainly like some mighty pretty hieroglyphics. I did well in Algebra I in high school. Like Wordsworth, I also really dug geometry. Then things started to fuzzy with Algebra II, and I finally got lost in the wilderness of trigonometry.
But if you've forged on ahead and are exploring linear algebra, check out Rob's fabulous free and excellent textbook material, which includes not just answers to the problems but examples of how one gets to the right answer.

Fever
The old woman who slid the pan
of cookies into my brain's oven
never came back. The cookies
turned into black dots that float
across my vision. I reek of burnt
dough. I lie on my side like a
buffalo who's reading Hegel
on a parched Kansas plain.
Invisible merchants empty
microscopic vats of hot slime
on my neck, my forehead.
A thin woman with cold fingers
practices scales on my spine.
A chorus of angelic rats
prevents me from nodding off.
I raise one hand as if
to conduct their performance,
and I pass out.

My Diary Went on Strike
My diary went on strike.
It said, "Damn, your life is dull.
I'm not letting my pages work for you
until something changes."
"So you're a union organizer now?"
I asked. My diary said, "Hey, I have
to protect my people, my pages."
I said, "Okay. I'll make it more
interesting. Even if I have to lie."
"That's fine," my diary said.
"Even if I make up shit?" I said.
"Of course," said my diary. "I'm
a labor-guy, not a tyrant."

An American Political Reformation
No, there isn't any revolution coming. For
the FBI will have infiltrated it before it
starts. A reformation (go figure) will be
more revolutionary. Here's the deal:
White working-class people will have to stop
taking Right Wing bait like dumb catfish.
Friends, the Black president isn't coming after
your guns. The real problem is that he and
every other president is willing to let
the system come after your wages, your cash,
your house. Shake hands with Black folks,
White folks. Shake hands with each other.
You';re not each other's enemy, you dig?
Neither Party gives a shit about you.
To repeat: Neither Party gives a shit about you.
To go Sixties for a moment: get your shit
together. Fuck with their heads. What if
neither Party could count on your support
unless it did something serious
about your economic well being? That
is a very simple question.
Stop letting these people pimp your
fears. Ask them how they will make your
life--your life--not the life of your guns
or your prejudices, better. Friends,
get your shit together, fuck with their
heads, and change the rules.

Wealth-Distribution in the U.S.: Video
Here is a link to a brief video about how wealth is distributed (who has what) in the U.S. If you think you might want to watch, you might first do two things: guess what the distribution is. That is, what % of the wealth is owned by the top 20 %? What % by the bottom 20%? And so on. Then sketch out what your preferable distribution might be. Of course, your view might be "let the chips fall where they may." But it's possible that you think that the graph-line should be a little smoother because (for example) local economies depend on people having enough cash to buy sandwiches, tools, cars, and so on. At any rate, here's the address: http://mashable.com/2013/03/02/wealth-inequality/

When An Epiphany Goes Flat
I was about to have
an epiphany when
the sum-bitch just
went all to hell on me.
It fell apart
and left me there staring
at the thing I'd been
staring at, feeling
nothing now. When
an epiphany goes flat,
you can't jack up
the frame and fix
the thing. You
just have to move on through
the dullness of
an everyday ride.

Overheard: It Changes, and It's Changing
The problem with
having everything online
is that it changes
all the time, and
it's changing.

Found Poem: They're All Dead, Ashes
Message on my phone
when I arrived home that
I was late for the grooming
appointment for my animals.
They'll be hard to groom.
They're all dead, ashes.....
