Carnival of . . . Mathematics?

February 11, 2007

Divest yourself of that tired and false notion that you’re bad at math. That’s hooey, though it probably sets your self-expectations low enough that it damages your math performance. Don’t make it a self-fulfilling prophecy.

New Carnival on the block: Carnival of Mathematics at Alon Levy’s Abstract Nonsense. It’s got some good stuff there for math teachers, and I suspect people with other interests will find something of interest, too. For me, for example, there is the link to the post that Fisks arguments of some of the more unsuspecting intelligent design fogmeisters. More pure historians may like the history of algebra post. There’s a lot more history and controversy in a post about why students should study math at all:

Biographical history, as taught in our public schools, is still largely a history of boneheads: ridiculous kings and queens, paranoid political leaders, compulsive voyagers, ignorant generals—the flotsam and jetsam of historical currents. The men who radically altered history, the great scientists and mathematicians, are seldom mentioned, if at all.

—Martin Gardner
quoted by G. Simmons, Calculus Gems

(Take THAT you creators of state history standards!)

Hmmm. I’m teaching algebra and geometry this week (“go figure!”). I may use some of that stuff.

Evolution Sunday, and history, and reason

February 11, 2007

Today is Evolution Sunday. It’s a day when thinking Christians make a modest stand for reason, it’s a day when caring Christians make a stand for facts and truth, versus calumny and voodoo science and voodoo history.

Debunking hoaxes — finding the truth about who put the first plumbed bathtub in the White House, repeating the debunking of the “Lady Hope hoax” that claimed Darwin recanted his life’s work on his deathbed, holding a spotlight on the facts of the Gulf of Tonkin Resolution and the events in the Gulf of Tonkin, highlighting the bravery of Cmdr. Lloyd Bucher and the crew of the Pueblo, noting that there never was a family of chainsaw murderers in Travis County, Texas — is difficult work. One wag I used to see posting on an internet bulletin board had a tagline, “Fighting ignorance since 1974 1973– it’s taking longer than I thought.”*

So, if you’re in church today, light a candle against the darkness, as Carl Sagan would say. Candles show us where demons are not, and where it is safe for humans to go. The more candles against ignorance, the greater the realm for human reason.

As Einstein almost certainly did not say, the difference between stupidity and genius is that genius has its limits. And as Frank Zappa probably did say, hydrogen is not the most abundant thing in the universe — ignorance is. Light some candles against ignorance today, in church or out of it. Reason gives us hope, and there is precious little of both today.

Be grateful for those things that keep us free, for those things that keep us seeking and acquiring knowledge, and for those people (like P. Z. Myers) who prod us — righteously — to stand up for the truth.


Carnival time!

Milan Township School No. 83, now at Northern Illinois University, DeKalb

Another History Blog reminds us that the the 47th History Carnival is up and running over at Progressive Historians.

Also, the 105th Carnival of Education is up at Alexander Russo’s This Week In Education.

Just sayin’, that’s all.


Teachers underworked and overpaid

February 8, 2007

Amazing.

Women clocking in, IBM archives

Via Education and Technology, I hear of a study that says teachers may not be undercompensated, with a supporting opinion piece in the Wall Street Journal, “$34.06 an hour: That’s how much the average public school teacher makes. Is that ‘underpaid?'”. The study comes from the Manhattan Institute, based on Bureau of Labor Statistics (BLS) figures, by Jay P. Green and Marcus A. Winters.

My escaped-sewage detector started clanging. Check out the lengthy explanation of methodology in the actual report. Such apologies up front should be a warning.

Of course, this raises issues about all the methodologies of the Bureau of Labor Statistics. Read the rest of this entry »


Wolf cry

February 7, 2007

Wolf reintroduction to several places in the United States has been such a success that the federal government is planning to remove the wolf from the endangered species list. (Ralph Maughn’s Wildlife News blog covers this issue in detail.)

As if in a bad melodrama, some states are rubbing their hands in glee, planning hunts to more than decimate the wild populations, once the delisting is complete. In its excellent science section yesterday, the New York Times explained the issue, and featured wonderful photos of wolves.

For anyone interested, the issues with elk are also covered at Maughn’s blog, with an photo showing some of the serious mismanagement of elk that may be alleviated with introduction of wild wolves as predators.

Wolf in Yellowstone national Park, NPS photo

In my several trips through Yellowstone National Park dating back to the 1950s, I had never seen a wolf until our last foray in 2003. At the same time, there are significant changes in the Park’s natural environment plainly visible. To my delight some prime moose habitat has returned in recent years. Grassy areas in some stream and river bottoms are turning back into more mixed plants, with willows and bushes intruding. This makes it more difficult to see wildlife, sometimes.

But it’s a good effect, and it’s a result of the introduction of the wolves. Elk graze in those areas, and they eat the willows and other bushes, keeping the river bottoms more like prairies than forest. Wolves love to hunt elk in those places, however, and the presence of wolves has put the elk on alert. Elk spend less time grazing the brush back, and the brush grows, providing habitat for a number of other animals, habitat that had been in serious decline.

One might wonder if some people are serious about these issues at all.

Tom Jefferson’s apples – for sale!

February 6, 2007

Moving to Utah (in the early Tertiary, if I recall correctly) took our family from the spud fields of southern Idaho, and plopped us in the middle of fruit orchards on the foothills of the Wasatch Front. There, protected from eastern winds and too-early sunlight by Mt. Timpanogos, farmers grew Bing cherries, pie cherries, peaches, apricots, and a lot of apples.

Our bus route to school was lined with orchards; missing the bus could make a wonderful experience wandering through the tended rows, finding the occasional clusters of wild asparagus (mark that down for next Sunday . . .), and discovering songbirds’ hiding places.

For a while our athletic fields abutted orchards. Late autumn football practices were sometimes made merrier when the migrant pickers took pity on us and tossed a few pippins over the fence.

In a perfect world that I imagine, orchards are close by many schools. Children get to see the blossom of the cherry trees heralding spring, and when they return to school in the fall they see the ripening apples, and then the harvesting of the apples. Time is measured, and history demonstrated, by the natural rhythms of agriculture.Newtown pippins, apples from Monticello

How about an apple from Thomas Jefferson’s farm? You can buy the trees from the foundation that runs Monticello. In that perfect world I imagine, the orchard near the school would feature at least one tree from Tom Jefferson’s orchard, one from George Washington’s, and several would be direct descendants of Ohio Valley apple trees planted by John Chapman, Johnny Appleseed himself. When teachers discuss the farms and actions of these men, even daydreaming kids could look out the window and see history staring back at them.

For the Albemarle (or Newtown) Pippin (malus cv.) pictured here, the Monticello catalog waxes freely:

In comparing the fruits of Europe to those of America, Jefferson wrote from Paris, “They have no apples here to compare with our Newtown pippin.” In 1759 Benjamin Franklin imported barrels of the fruit into London and, by 1807 it appeared on the Horticultural Society of London’s “Select List” of apples. England’s Queen Victoria once waived the import tariff for the pippin and it was said that, “they were eaten and praised by royal lips, and swallowed by many aristocratic throats. The name Albemarle Pippin first appeared on the editorial page of Richmond, Virginia’s The Southern Planter in 1843, saying “the very best pippin we know is grown in the county of Albemarle, ” which is where Monticello is located. The green-skinned, yellow-fleshed pippin is known as the Prince of Apples. It’s mouth-watering flavors actually improve with storage. This apple is self-pollinating, but planting more than one enhances production. Grows 14 to 16 feet in height. Early 1700’s.

Zones 5-9.

Trees begin shipping February 26; supplies are limited. Proceeds support the restoration and education programs at Monticello. One may purchase a part of history to come live in one’s yard.


Pork producers agree to reason on breast feeding

February 6, 2007

Humor would be impossible without the newspapers, but a lot of really funny stuff happens that never makes it there.

Shortcut: The National Pork Board is working for a happy solution with The Lactivist, who had previously been threatened with legal action for promoting breastfeeding with a t-shirt that says: “The Other White Milk.”

When I taught in a program that included the district’s teen pregnancy courses, I had a kid who one day, out of the blue, insisted that he’d never let his “baby momma” breast feed his son, “because I don’t want him growing up to be homo.”  When such eruptions of ignorance and bigotry occur, what is to be done?

As luck would have it, he was studying the Progressive Era, and we had a lengthy discussion on public health issues, and how to improve the health of the population overall.  We found several websites (which, if available through the district’s filters, were non-objectionable) discussing the value of breastfeeding in giving kids a head start on health and brain development.   My student was skeptical.

In the face of that kind of health-threatening ignorance and such bizarre hoaxes, one quickly comes to understand that radical campaigns to promote breastfeeding are required — even those that depend on humor.

You will get a few laughs, and eventual hope for a happy resolution, following the story of Lactivist’s tussle with the marketers at the Pork Council, with a special tip of the old scrub brush to Skippy the Bush Kangaroo.


Noteworthy: Primordial Blog

February 4, 2007

Thanks to P. Z. Myers, I found a very interesting blog by an intermediate grades teacher in Ross River, Yukon Territory (that’s Canada, folks).  Go check out Primordial Blog.  It’ll give fits to hoaxers of all stripes, including especially intelligent design, creationism, and history hoaxers.


Dissent effective: Stimson resigns from detainee post

February 4, 2007

Charles Stimson resigned Friday. Stimson is the attorney who was deputy secretary of defense for detainee affairs. You may recall he was the person who suggested in a radio interview that business clients of lawyers who provide legal counsel to detainees should pressure the attorneys not to represent the detainees, a suggestion that is contrary to the ethical canons of attorneys.

According to the New York Times:

Stimson drew outrage from the legal community — and a disavowal from the Defense Department — for his Jan. 11 comments, in which he also suggested some attorneys were being untruthful about doing the work free of charge and instead were ”receiving moneys from who knows where.”

He also said companies might want to consider taking their legal business to other firms that do not represent suspected terrorists.

The Defense Department disavowed the suggestion. Attorney General Albert Gonzalez also disavowed Stimson’s remarks. But Stimson said that the controversy hampered his effectiveness on the job. The NY Times said:

Stimson publicly apologized several days after the radio interview, saying his comments did not reflect his values and that he firmly believes in the principles of the U.S. legal system.

But it didn’t completely quiet critics.

The Bar Association of San Francisco last week asked the California State Bar to investigate whether Stimson violated legal ethics by suggesting a boycott of law firms that represent Guantanamo Bay detainees.

Chuck Colson hoaxed, or hoaxing; you should act

February 3, 2007

Chuck Colson claims to have found God, while in prison, and changed his ways. He’s got a newspaper column and radio feature called “Breakpoint” which generally covers issues at least tangentially related to ministry and church work.

But he’s either fallen victim to a great hoax, or he’s in on it and spread it.

Ed Brayton at Dispatches from the Culture Wars alerted us to Colson’s “Breakpoint” commentary dated February 2, in which Colson repeats the disproven claims that Judge John E. Jones of the Middle District of Pennsylvania “plagiarized” significant portions of his decision. The charges are completely out of line, and have not held up under scrutiny. The claims were invented by people at the Discovery Institute who have no knowledge of how federal civil trials work, who misinterpreted trial procedures, and who made an invalid count of the words in the decision (failing to account for most of the 129 pages of the work for reasons that have never been explained).

If this catches you unaware of the issue, you can catch up with several posts. Attorney and Panda’s Thumb contributor Tim Sandefur explains how the charges are false here. Sandefur’s earlier explanation of the statistical errors behind the false claims is here (also at Panda’s Thumb).

You should act. If your local newspaper carries Colson’s column, notify them of the hoax. Give them the links above, and urge them to contact the press people at the National Center for Science Education for comment. Tell them they can quote Panda’s thumb, and that they can contact Sandefur, Brayton, or me, for comment.

Similarly, if your local radio station carries Colson’s commentaries, notify the station. Stations need to check to be sure they are not broadcasting hoaxes for license renewal reasons (though the FCC polices this issue rarely, and not often well).

Were Colson a practicing attorney, of course, he’d probably remember how federal trial procedures work, and not make such errors.

You can help him recall.


Seymour Papert recuperating at home

February 2, 2007

MIT’s Media Lab last updated Seymour Papert’s condition on January 10 — it said he’d been moved to a rehabilitation facility closer to his home, in Bangor, Maine. Vietnamese publications, including VietnamNet Bridge, report he’s home now (Vietnam was where he was struck by a motorbike in early December).

Prof Papert’s family said that he had been discharged from the hospital in Boston in the U.S. He is now still undergoing treatment at home. Luckily enough, he will not have any after-effects after the head trauma and now he can speak.

The $100 laptop idea, the XO Computer, steams on.


Eleanor McGovern

February 2, 2007

The past few weeks have been studded with the deaths of people important to my life, or important in history. The string is a long, unnecessary reminder that there are a lot of people holding history in their memories whom more historians need to get out and interview, even (and perhaps especially) high school-age historians.

Eleanor and George McGovern

Eleanor McGovern died in Mitchell, South Dakota, last week. I wonder how many of the town’s high school history teachers ever thought to invite the woman to speak?

McGovern was the probably the first spouse of a presidential candidate to campaign alone, without the candidate along. The respectful, rather long obituary in the Los Angeles Times made that a focus point of its tribute (free subscription will eventually be required). That was the place I first got the news of her death, while I participated in a Liberty Fund seminar in Pasadena, California, last week.

I was recruited to politics by a McGovernite in early 1972, in Utah. Over the next few months we saw Eleanor McGovern look cool, calm, intelligent and charming in her husband’s losing campaign. She may not always have been so cool as we saw — the Times piece mentions she was nearly ill before the first-ever Sunday interview program solo appearance by a candidate’s wife.

That she was both pretty and smart probably scared the opposition more than anything she ever said. Read the rest of this entry »
