Algebra 10-12 assignment; May 5

We went over our quiz today in class before getting started on today's lesson.  Today's lesson focused on being able to add and subtract radical expressions.  We worked to get like radicals in the equations first, before then adding and subtracting to finish the problem.  We went through several examples in class together before getting started on the homework assignment.

Wasicu at Chankpe Opi: A White Man at Wounded Knee V


A single troop—who knows who?—tried to wrestle Black Coyote, one of the Sioux men. Some say he was deaf. At the same moment, the medicine man gets to his feet, picks up a handful of dust, and throws it at the soldiers, his shrieking exhortation continuing in the Sioux language. The soldier and Black Coyote wrestle for the possession of a rifle, while down the line another soldier begins struggling with another for a rifle wrapped in the blanket covering one of three young men standing close together. The medicine man keeps telling his people white bullets will not harm them.

One shot. Whose was it? Did it come from Black Coyote in the struggle? No one knows for sure. But in a moment all hell broke loose, and, for less than a half hour, what follows is a fierce and bloody battle waged hand-to-hand in a council circle soon choked by dust and smoke, and thick with bullets, most of them from army issue rifles, bullets that flew indiscriminately, killing many of the Sioux in the middle, as well as bluecoats on either side. That the cavalry could have avoided shooting each other at such close quarters seems impossible, despite claims to the contrary in military hearings conducted later.

An old woman who used to live down our street claims that out here on the prairie we get only about ten sweet days a year. Prairie cold locks life in its frigid jaws; the heat wilts anything that grows; and always, the wind blows. In the summer, it’s capable of sand-blasting your face; in the winter, its bite is not only dangerous but deadly. But that morning, December 29, 1890, the wind stood still. When you look down now, from the promontory where the First and Second Artillery have been firing those Hotchkiss guns into the horror beneath them, imagine a cloud of dust and smoke so thick as to stop breath. In seconds, in the very middle of the fray, combatants cannot see each other, but blindness doesn’t stop the killing. Seventeen miles away, at the Pine Ridge Agency, people claimed to hear the firing.

Just exactly who fired first might never be established, but there is no question whose rifles ended the massacre. With the first shots, hundreds of Lakota women and children run away into that ravine you see just beyond the fighting. With dozens of their own down in the middle of the madness, Forsyte’s men are in no mood to take prisoners, so for several hours after the bloody combat that began in front of Big Foot’s tent, scattered gunfire continues as far as three miles away, up and down the ravines that cut through the tawny prairie around the creek called Wounded Knee. What began in intolerable heat ended in cold-blooded murder.

If you’d like, perhaps you could walk down into those ravines, no more than a half mile from where we’re standing. There are no markers anywhere, like the ones at Little Big Horn, no whited stones to mark the spots where people fell. But even in their absence, ghosts linger.

That afternoon, when the shooting ended, Army personnel loaded 39 of their wounded into wagons, along with their dead, 25. Fifty-one wounded Sioux were located, 47 of them women and children, some of whom—like six of the cavalry survivors—would soon succumb to their injuries. The Sioux dead were left on the field and in the ravines, but exactly how many had been killed will never be known. Native people consider 300 a fairly just estimate.

That night, a blizzard came in on the wind and laid a gossamer veil over the carnage—some say mercifully; some think the hand of white man’s God was simply covering their sin. Wounded Knee was the final military action in the Plains Indians Wars, the horrid, bloody conclusion of a cultural and religious confrontation that, from my vantage point, a white man at Wounded Knee, looks even today like something obscenely inevitable. Millions of white people—my own Dutch immigrant ancestors among them—went west for cheap land they assumed the Sioux didn’t value. After all, where were the improvements, the tree lines, the fences, the buildings, the cut sod? Millions of white people—my own ancestors among them—thought our holy book to a pagan people was a generous gift for the millions of acres those people had once roamed in freedom. My own family included, we wanted to own what they wanted to honor.

But the Lakota people lost far more than those buried on the hill where we’re standing. They lost what the cavalry and the government called “the battle”; they lost the war; they lost their way of life. “And I can see that something else died there in the bloody mud, and was buried in the blizzard,” Black Elk says. “A people’s dream died there. It was a beautiful dream.”

Morning Thanks--all those who help



Once upon a time, I helped shingle a three-story house in Sheboygan, Wisconsin, which meant ascending an old wooden extension ladder with a bundle of shingles on my shoulder, a ridiculous circus act. I needed one hand to keep that 90-pound bundle on my shoulder; that left only one on a ancient paint-spattered ladder that bowed like an buggy spring when me and that bundle were aboard. I lived. But I never forgot.

For maybe two weeks total, I worked for a construction crew putting a new interstate highway up the lake shore. They paid good money for every last muscle in my body. It took no brains at all to cut sod or load it on flatbeds, even fewer to lug those heavy sod balls in soft dirt up 45-degree interchange inclines.  It just about killed me, six to six every day save Sabbath. My body--I was 21 years old!--taught me what the word overtired means.

Once upon a time, years ago, my father-in-law and I drove down to Sioux City to work at flood relief. Perry Creek had come up in early summer cloudbursts that wouldn't quit. Dozens of homes went under in a muddy torrent and ravaged an old area of the city that could hardly be called "exclusive." Houses that could be saved had to be disemboweled. 

No job I ever worked at--sod balls or shingle bundles--was an butt-ugly as lugging 10-gallon buckets of muck up people's basement stairways, trip after trip after trip, and emptying those buckets outside. In one house a wall of paperbacks had caved in, and a couple hundred books were lodged in mud so thick you sometimes worried you'd be gone yourself in another ten minutes. 

I remember an old African-American woman sitting at a table while an bucket brigade of volunteers tramped up her stairs and past the open door to her kitchen, each of us heavy laden with buckets of sludge, her stairway and back hall a pig sty of slop beneath our muddy boots. 

After last night's storm, we're coming close to 15 inches of rain here in the last month, a dozen more than normal. Lots of houses have been inundated, then emptied, a lifetime of possessions transformed into trash. Even without the mud, cleaning out a soggy house means watching your life turn to garbage. 

This morning I'm thankful for the dozens, the hundreds, the thousands of volunteers who, today again, will go down into the bowels of horrible human loss and try to make life easier for those who, right now, can't see but an inch or two past their own muddy basements.

All those volunteers, today once more, will be doing good work. Ugly work, but good work, blessed work, God's own hands in a flooded, muddy world.

Geometry assignment; March 4

We went over our chapter 8 test today before going through the lesson.  Today's lesson dealt with tangent lines and circles and how calculation problems can be solved using tangents to circles.  We walked through several examples before getting started on our homework at the end of the period.

Book Review--Origins


Here's the rub. Once upon a time--and still today--people who believe in a Christian education used evolution as a kind of shibboleth. Those of us who chose to send our kids to a Christian school could always say, "You know, if our kids went to public schools, they'd be taught that their ancestors were chimpanzees--how does that square with biblical thinking?"

End of conversation. Maybe. Creation was a mainstay, a foundational principle. That God almighty created all things was a given in what most people considered a Christian worldview. Belief in evolution was belief in Godlessness. 

And it still is.

Well, somewhat. 

The alternatives, for some, are few. Either He did or He didn't. Now if we hang two scenarios on that "either-or" dilemma, only two possibilities exist: either 6000 years ago God almighty snapped his fingers and it all started on time; or, creation is a cute little story for pre-schoolers.

Already in 1925, the theory of evolution was a lightning rod. When William Jennings Bryan, a fiery Christian populist known for his passionate oratory, entered a Tennessee courtroom, not having practiced law for more than thirty years, he was taking on nothing less than atheism itself.  On the other side stood an equally powerful heavyweight advocate--and agnostic--Clarence Darrow. For the two of them, the question of creation vs. evolution was perfectly either/or. 

That trial set a paradigm in the American mind ever since: evolution is Godless; creation is Godly.

Wouldn't it be sweet if life was that simple?

We've been reading Origins, a wonderful little compendium of the parameters of the conversation, for quite some time now, a fascinating study. One of the authors, Loren Haarsma, grew up just down the road in Orange City and is, in fact, some distant relative of my wife. His accomplice happens to be his wife, who, like Loren, is a pedigreed scientist who's made scientific research her life's work.

It's rare to find a book so generously written. That the Haarsmas have a point of view in all of this goes without question, but their largess for those who don't share their views is immensely gracious, given the passion most of us bring to the arguments.

There are land mines in the war between creation and evolution, plenty of them. The Haarsmas don't try to sidestep them. They go out of their way to find them and open them so the reader doesn't miss either the land mines themselves of the character of their composition. This little study does us all well because their mission impossible is to discuss an issue that has made people point their fingers--and wag them--ungraciously for a long, long time.

There's nothing new about the debate--except science. What has changed since that old steamy Tennessee courtroom is what we know about ourselves and our world. Today, solid scientific evidence exists about genes and chromosomes, knowledge that could barely be theorized just a few decades ago. That knowledge has enriched our sense of origins, of how humankind has developed. After all, the science of genetics tells a story, too, a story we can't simply burn or deliver to the landfill.

Orthodox Christianity has always recognized two sources of revelation--that which we discover in the Bible, the Spirit-breathed Word of God; and that which we see around us, God's own continuing revelation in creation.  "The heavens declare the glory of God," David says, because every last painting in the sky teaches us his glory. No one on the face of the earth misses that sermon.

Balancing the weight of the two can be something of a high-wire act. How can ordinary Christian believers go to the bank with a six-day creation and the fossil record or the science of genetics? Answering that question is tough stuff.

What the Haarsmas do in Origins is try to explain the strengths and weaknesses of various deeply held points of view on just exactly how God almighty created this world of ours--and His.

We live in an immensely fractured world. Even in churches, politics are often far, far more highly regarded than theology. Have no doubt, Origins could raise cain and probably does in some strongholds. 

But the Haarsmas have gone out of their way to treat just about everyone with dignity and justice. The book--it's not long and very methodical and comprehensive--is a real blessing.

Geometry assignment; May 1

We went through another entry task today practicing the use of our various formulas.  We then spent some time taking a look at some animations of how cones are constructed from triangles and how they are related to cylinders.  The class got some new formulas for how to work with cones and then did a couple of sample problems together before getting started on the homework.

Quiz on volume and surface area of solid objects tomorrow.

Geometry assignment; May 7

After going over the homework, we spent time working on the final section of chapter 12.  The topic for today was dealing with the ratios among similar solid objects.  The ratio between single dimensions  (height, slant height, perimeter, etc. is equal to the scale factor.  The area ratio is equal to the scale factor squared.  The volume ratio is equal to the scale factor cubed.  We did a few sample problems involving these ratios together before getting started on our homework.
