Fun with Numbers

Wednesday, November 14th, 2007

From the American Research Group:

November 13, 2007 – Impeachment

A total of 64% of American voters say that President George W. Bush has abused his powers as president. Of the 64%, 14% (9% of all voters) say the abuses are not serious enough to warrant impeachment, 33% (21% of all voters) say the abuses rise to the level of impeachable offenses, but he should not be impeached, and 53% (34% of all voters) say the abuses rise to the level of impeachable offenses and Mr. Bush should be impeached and removed from office.

The respondents didn’t specify whether they were specifically referring to the administration’s policy on torture. They didn’t say if they were talking about how they cherry-picked intelligence to justify a wrong-headed war, or how they compromised national security by outing a covert CIA operative, merely as retribution for her husband calling them on their lies. The respondents may not have been specifically responding to warrantless wiretapping and secret military tribunals. They may have simply been thinking of how the administration handed over all government regulation to the industries being regulated. The data doesn’t say. All they were asked was if President Bush abused his power, and 64% said he did. The data also doesn’t show what the other 36% were thinking.

When you look at the data, though, something else is striking.

I’m surprised, though I guess I shouldn’t be, that so few people gave Response 2. Imagine a graph of this data. Usually a distribution like this would slope up, slope down, or rise in the middle like a bell curve. That this data set has such a sharp dip in the middle is a testament to just how polarizing this president has been. 64% of Republicans feel that President Bush has not abused his powers as president at all, while 50% of Democrats feel he should be impeached for it.

Also, more than one-fifth of respondents in general felt that his abuses had risen to the level of an impeachable offense, but that he shouldn’t be impeached. Isn’t that being soft on crime? Or perhaps we just remember the last time an opposition Congress impeached a sitting president, and are unwilling to go through all of that again, even if it’s warranted this time.

Because for 36% of the population, warrants are sooooo 20th century.

Retargeting

Wednesday, August 22nd, 2007

They say a picture is worth a thousand words. But what if you only have room for 650? Enter “Content Aware Image Resizing” or the retargeting of images:

This is truly amazing, another step in the ongoing campaign to make images as dynamic as text in the XML Internet.

It does raise some questions about the medium of photography, though. This isn’t the first time images have been digitally altered to be sure, but there does seem to be a difference here. To begin with, a photograph should not be mistaken for reality. Photographers make choices, and a photograph is a selective representation of the world. A resized photograph, I would argue, is basically the same photograph. A cropped photograph is not, but it can be considered another photograph, as it is a different selective representation of the real world. A digitally altered photograph can no longer be considered a photograph in the same way, but it remains a visual representation of an imagined world.

What, then, is a retargeted image? It is a new concept for a new world. Take the example of the image of the two figures on the beach (about 46 seconds into the video). Resizing the image would make it hard to see the figures. Cropping the image would lose one of the figures. Retargeting the image keeps both figures in their current size, and loses only the beach between them. This may seem like an ideal solution, but what is lost is the distance between the two figures. That is a major element of this photograph. It was deleted, not for artistic or functional purposes, but for practical purposes, to help it fit better on the page. The thousand words represented by a picture can now be cut down to just the verbs and nouns. And one imagines this being one day automated, even built into Web browsers of the future – a future where everything is as adjustable as Quick Text Shakespeare, and with similiar nuance.

Even the phrase “Content Aware Image Resizing” gives me the willies in the same way that the term “content provider” seems to imply that the content is just one of many elements that make up a deliverable product. Under this system, Shakespeare was a content provider. And the process described in the video is not aware of content. For that, you still need a human.

I know I’ve blogged favorably about the changes the Internet is bringing to society, and many of them are inevitable, but others are not, and we have a responsibility to keep up with the changing definition of information literacy. Now we have one more question to ask ourselves when we see a photograph online.

I was originally posting this because I thought it was way cool. But I don’t want us to be so dazzled by the new technologies that come out that we stop asking the critical questions.

Bothered

Friday, August 10th, 2007

I know this blog has been overly focused on politics lately, but I’m really bothered and I need to vent yet again.

I’m not bothered that the President failed to disclose a serious medical condition to the American people for a year. If that was the worst thing he did as President, he’d be Jed Bartlet.

I’m not bothered when right-wing commentators call for another 9/11 to “save America” from spirited debate over policy issues and return to a more unified time when everyone was crazed with fear and ready to do whatever the President wanted. Fear is what these people do best.

I’m not bothered by a member of the current administration’s Civil Rights Commission pondering a return to Korematsu. It’s not like he was advocating it, after all.

I’m not bothered that the Secretary of Education would rather read Harry Potter than Shakespeare. Shakespeare can be difficult, and I’ve heard good things about the Harry Potter books. Even the Shakespeare Teacher likes to relax with some lighter fare every now and then.

No, gentle readers, the Republicans aren’t bothering me so much anymore. I think by now we all pretty much know what to expect from them.

It’s the Democrats who totally caved on warrantless wiretapping that are bothering me:

Buckling in the face of familiar scare tactics – and looking to go on vacation – Congress caved on domestic surveillance this past weekend. It handed the White House temporary authority to monitor, without warrants, Americans’ international phone calls and e-mail.

Which brings me to Al Gore. In my opinion, Al Gore is the only person in the country who 1) gets it, and 2) has a strong chance of winning the Presidency.

Because of this, he has a moral obligation to run. He has laid out the most serious challenges facing us today and we have listened. But he may be the only person who can be the change he wants to see in the world. He can’t honestly think that giving a Keynote presentation on climate change can compare to actually being the President. So what’s going on? Is he biding his time, allowing all of us to beg him to run, rather than entering the race now and becoming a target? Or is honestly not planning to run?

I’m bothered by the current state of politics in this country. I’m bothered by the abusive Republicans and the enabling Democrats. And you know what? So is he. So I’ll wrap up this post by linking to rundammit.com, because I’m sick and tired of being bothered by this sorry excuse for a government we have failing to run this country.

It’s time, Al. Step up.

Question of the Week

Monday, August 6th, 2007

In a poll taken over a decade ago, 96% of Canadians said they preferred their health care system to ours.

A more recent poll indicates that 64% of Americans think “the government should provide a national health insurance program for all Americans, even if this would require higher taxes”.

Michael Moore’s film Sicko is the fourth highest grossing documentary of all time.

And millions of Americans have no health insurance at all.

What specifically is it going to take to get Universal Health Care in this country?

Arts Education

Sunday, July 29th, 2007

The Center on Education Policy released a disturbing new study this week, measuring the effects of No Child Left Behind:

The report finds that approximately 62% of school districts increased the amount of time spent in elementary schools on English language arts and or math, while 44% of districts cut time on science, social studies, art and music, physical education, lunch or recess.

Now, I’m pretty much appalled by all of the cutbacks, but I’ll leave the bulk of it to ScienceTeacher.com, SocialStudiesTeacher.com, and LunchTeacher.com. I’m ShakespeareTeacher.com, so I want to talk about arts education.

(And let’s make no mistake – the extra time being spent on ELA isn’t being spent on literature. It’s being spent on test prep, and more test prep.)

Arts education is absolutely essential for students preparing for the world that we’re currently living in. With the image continuing to gain dominance over the written word, people who can demonstrate artistic ability are highly marketable in today’s economy. From graphic designers to documentary filmmakers, those who can master today’s tools of communication are able to command a wider audience and expand their range of communication. In the connected world, this is real currency.

And even if all of that weren’t true, the arts teach us how to identify problems and solve them with creativity and discipline. Those skills help us in any endeavor.

I came across a website for an artist named Jen Stark, who creates sculptures from construction paper that won’t help anyone pass a reading test any time soon. But they bring beauty into the world, which is worth at least a link from my blog. Take a look at her work, and tell me she didn’t have to develop some pretty sophisticated math skills along the way.

Or take French artist Huber Duprat, who recruited caddis fly larvae, who typically create protective shells out of silk and their surrounding materials, and placed them in an environment of gold flakes and precious gems. The result is a combination of art and science that boggles the mind. Click the picture below to see the video.

Or take a look at the Universcale by Nikon, an application of the mathematics of scale to allow human comprehension of the natural universe, and tell me your appreciation of it isn’t primarily aesthetic.

I wonder what Leonardo DaVinci would have thought about eliminating arts education to teach math. What would Shakespeare have thought about eliminating arts education to teach literacy? What would Descartes say about eliminating science to teach math? What would Hemmingway think of eliminating social studies to teach literacy?

Reading and math are important skills. But even if an educational system were somehow able to acheive 100 percent literacy and numeracy, and nothing else, it would still be a failure.

Whisper Down the Lane

Wednesday, June 27th, 2007

I wanted to clear up that my post last week, Lies Like Truth, was criticizing the article in the Scotsman and not necessarily the academics being cited. If, in fact, they are making the claim that the article says they are, they are included in my critique, but I suspect the article doesn’t do justice to their positions. If I had to guess, and this is only conjecture, I would say that they are simply stating that the version of history told by Shakespeare first appears in Wyntoun. No big deal. The only reason it’s worth mentioning is that they were about to say so on a radio special. But that wouldn’t make a good story for the Scotsman, and thus this whole business of being “lifted, almost word for word in places” rears its ugly head.

Case in point: here’s another story from DailyIndia.com and NewKerala.com from Asian News International that seems to have been “lifted, almost word for word in places” from the original story in the Scotsman. Look at the two stories side by side and the ANI piece, appearing the next day, reads like a high school student clumsily paraphrasing from an encyclopedia. But upon closer inspection, the ANI article makes some bold statements that the Scotsman was careful only to imply, despite the fact that the Scotsman article was clearly its one and only source.

For example, the Scotsman plants the idea of the authorship question like so:

In a radio programme to be aired today, Scots historian Fiona Watson and literary expert Molly Rourke claim the story of Macbeth was penned by a Scottish monk on St Serf’s Island in the middle of Loch Leven 400 years before William Shakespeare even drew breath.

Shift around the letters, and the ANI version becomes:

Scots historian Fiona Watson and literary expert Molly Rourke are claiming that the credit for ‘Macbeth’ doesn’t belong to the Bard of Avon, but to a Scottish monk named Andrew de Wyntoun from St Serf’s Island in the middle of Loch Leven who wrote the play 400 years before Shakespeare was even born.

So we go from the idea that Wyntoun penned the story of Macbeth (the man), which is true, to the idea that Wyntoun wrote Macbeth (the play) instead of Shakespeare. Quite a leap. I can only imagine, but I hope I’m right, that Watson and Rourke would be horrified to see these claims attached to their names.

Even the title of the ANI article is dodgy:

Did a Scottish monk write Macbeth instead of Shakespeare?

Oh, I can answer that one.

No!

Lies Like Truth

Tuesday, June 19th, 2007

So, this article has been getting a lot of attention on the Internet, and I feel I need to respond:

In a radio programme to be aired today, Scots historian Fiona Watson and literary expert Molly Rourke claim the story of Macbeth was penned by a Scottish monk on St Serf’s Island in the middle of Loch Leven 400 years before William Shakespeare even drew breath.

Pause for laughter.

In Macbeth the Highland King to be broadcast on BBC Radio Scotland, Watson says Macbeth and his wife, Gruoch, were in fact “respected, God-fearing folk”.

According to Watson, the “almost entirely fantastical view” of Macbeth and Lady Macbeth drawn by William Shakespeare is lifted, almost word for word in places, from a collection of folklore recorded by St Serf’s monk, Andrew de Wyntoun.

Wow, there’s so much wrong with that, it’s hard to know where to start.

First of all, the “almost word for word” case is never made, at least not in the article. The few points of similarity between the two texts that are mentioned are dealt with below. But there really was a historical Macbeth, and so any two accounts of his life are bound to have some similarities, whether they be historical or legendary.

Did Shakespeare have an “almost entirely fantastical view” of Macbeth? Yes. He was a playwright, not a historian. He often made changes to history to suit his dramatic purposes. That’s what he’s supposed to do. He was also writing for King James, who was a direct descendant of both Malcolm and Banquo. So of course he’s going to make them good and noble and make Macbeth a savage butcher. He knew which side of his bread was buttered.

Also, the Andrew Wyntoun text is from 1420. How is that “400 years before William Shakespeare even drew breath” which he first did in 1564? And if the text really were from 1164, it would not be at all readable to a twenty-first century English-only speaker, as this text somewhat is. Check it out.

But the most striking part of the article is that it completely ignores the fact that we already know what Shakespeare’s source was for the events described. It was Raphael Holinshed’s The Chronicles of England, Scotland, and Ireland. In fact, not only was Holinshed’s Chronicles a major source for Macbeth, but also for King Lear, Cymbeline, and all ten of Shakespeare’s history plays. If you don’t know that, it’s easy to be taken in by the following observation in the article:

Referring to Shakespeare’s prophecy that Macbeth shall be safe until Birnham Wood comes to Dunsinane and that no-one “of woman born” shall harm Macbeth, Rourke explained in Wyntoun’s work: “The person [Macbeth’s mother] met later came and saw her, gave her a ring, and prophesied about what was going to happen in the future. One of the things he said was that this child they’d had would never be killed by man born of woman. Wyntoun also recorded that Macbeth believed he’d never be conquered until the wood of Birnham came to Dunsinane.”

Thanks to the wonderful Furness Collection at the University of Pennsylvania, we can see the source for this on Page 174 of the Historie of Scotland section of Holinshed’s Chronicles:

And suerlie herevpon had he put Makduffe to death, but that a certaine witch, whom hee had in great trust, had told that he should neuer be slaine with man borne of anie woman, nor vanquished till the wood of Bernane came to the castell of Dunsinane.

The witch told Macbeth, like the apparitions do in the play, not a person telling Macbeth’s mother and giving her a ring.

The article continues on with reckless abandon:

The historians claim another element of Wyntoun found in Shakespeare is the three witches that open the play. Wyntoun wrote: “Ane nicht, he thoucht while he was sa settled [that] he saw three women, and they women then thoucht he three Wierd Sisters most like to be.

“The first he heard say, ganging by, ‘lo, yonder the Thane of Cromarty’.

“T’other woman said again ‘of Moray, yonder I see the Thane’.

“The third said ‘yonder I see the king’.”

Rourke and Watson say the resemblance to the witches’ prophesy in Shakespeare’s Macbeth – in which the first hails him as “Thane of Glames”, the second as “Thane of Cawdor” and the third proclaims he shall “be King hereafter” – is too great to be co-incidental.

We simply need to turn back to page 170 of Holinshed to see where Shakespeare found this, and thanks to the extraordinary Folger collection we can see a much easier-to-read copy of Holinshed’s version of the story:

Shortlie after happened a strange and vncouth woonder, which afterward was the cause of much trouble in the realme of Scotland as ye shall after heare. It fortuned as Makbeth and Banquho iournied towards Fores, where the king then laie, they went sporting by the waie togither without other company saue onelie themselues, passing thorough the woods and fields, when suddenlie in the middest of a laund, there met them three women in strange and wild apparell, resembling creatures of elder world, whome when they attentiuelie beheld, woondering much at the sight, the first of them spake and said: All haile Makbeth, thane of Glammis (for he had latelie entered into that dignitie and office by the death of his father Sinell). The second of them said: Haile Makbeth thane of Cawder. But the third said: All haile Makbeth that heereafter shalt be king of Scotland.

I’ll allow you to examine that scene in Shakespeare and decide for yourself which of these two accounts was most likely Shakespeare’s source.

It’s entirely possible that Wyntoun’s work was a source for Holinshed (or Harrison, Leland, etc.), or a source of a source, or at some point they had a common source. But the idea suggested by this article, that Shakespeare somehow “lifted” Macbeth from Wyntoun, is absurd.

UPDATE: A follow-up post.

Conundrum: The Math of Khan

Tuesday, May 8th, 2007

When I first started this blog, one of my very first posts suggested that almost all of the current natives of Mongolia and China were probably descendants of Genghis Khan. I literally had no readers at the time – I hadn’t yet told anyone about the blog – and so there was nobody to challenge my sweeping statement. I didn’t even make an argument. I’d like to give my argument now, and reopen the question as a Conundrum.

The idea was based on a National Geographic article about the biological legacy of Genghis Khan:

An international group of geneticists studying Y-chromosome data have found that nearly 8 percent of the men living in the region of the former Mongol empire carry y-chromosomes that are nearly identical. That translates to 0.5 percent of the male population in the world, or roughly 16 million descendants living today.

I went on to note:

16 million descendants. And that’s only men descended from Khan directly through the male line, father to son, for the past 800 years. The total number of Khan’s descendants living today is truly incalculable.

If you figure an average of four generations per century, that’s 32 generations between Genghis and his living descendants. Each person living today should have around 2 to the power of 32, or roughly 4.3 billion, living ancestors that are contemporary with Khan. Obviously, many individuals will have to be counted more than once, so let’s take a different tack.

Let’s pick a year somewhere between 1200 and 2000, say 1500. The total population of mainland Asia in 1500 was 268,400,000. Each living person today would have approximately 2 to the power of 20, or about a million, ancestors who were around in 1500 (and that’s if we don’t count anyone with a living parent).

So how many of the 268,400,000 around in 1500 were Khan’s descendants? Well, there are 16 million men living today that share the Y chomosome. If Khan and his direct male heirs had an average of 1.68 sons over 32 generations, that would give us our 16 million. That would only account for 505 men carrying that Y chromosome in 1500. But that calcuation leaves out two factors.

First, by 1500, Khan’s seed had been pretty well spread. The factors that account for his prevalence today came mostly into play during Khan’s life and the few generations following (see the article for details). So the distribution was a lot more top-heavy than the calculation above would suggest.

Second, we’re only counting direct male-line heirs. Passing a Y chromosome down from father to son over 32 generations is only one of 4.3 billion different permutations of inheritance. Each of those 16 million Y chromosome carriers alive today probably has an average of at least one sister or daughter. That doubles the known descendants right there. Extend that back over 32 generations, then consider all of their descendants, and you get the idea. If we change “average of 1.68 sons over 32 generations” (which we know is true) to “average of 2 children of either sex over 32 generations” (which doesn’t seem like too great of a leap from there), then 16 million becomes 4.3 billion, greater than the population of mainland Asia today.

It seems to me that today’s ethnic Mongolians and Chinese would almost all have to be descended from Khan, some many times over.

Now I am no math expert. I’m a Shakespeare Teacher. It’s very possible I could be wrong about this. I’d be interested to hear what other people think, particularly people with more professional experience with statistical analysis.

And I should also point out that I pin no political, moral, or judgmental significance to being a descendant of Genghis Khan. This is simply a math, history, and logistical Conundrum. I truly hope no offense is taken (though if you read my original post and the Economist article it is based on, it actually seems to be a point of pride for both Mongolia and China to be the descendants of Khan). And my family comes from Belarus, so this would mean I’m probably a descendant of Khan as well. So don’t screw with me.

Now, with all that in mind, for this week’s Conundrum, I hereby submit my original conclusion up for public scrutiny:

So, China and Mongolia should probably stop arguing over which of their people are the true heirs of Genghis Khan. My guess is, almost all of them are.
