Scientific American, you ruined my day, but thanks, I needed it.
Silly me for thinking the Math Wars ended when Mathland bit the dust a couple of years ago. Last May, according to this month’s Scientific American, the Seattle School Board adopted the “Discovering Mathematics series, a reform-math high school text that uses student investigations as a means of discovering math principles—such as using toothpick models to derive recursive sequences.”
I looked at it for as long as my stomach could bear — at least at the one chapter that’s available online as a .pdf file here. It’s wretched. Wrong. Not only wrong like in I-don’t-like-it wrong (which it also is), but falselike wrong. And bad, stupid, dumb, and foolish, among other things. It would take me too long to point out all the things wrong in just the first few pages. (I won’t lie. There were some good things, but not many.)
I don’t think the students who wouldn’t have gotten much out of mathematics curricula in the ‘60s will do any better with this. For the students who want to learn mathematics, unfortunately, school will be even more of a waste than it used to be. They should do their best (especially if they go to public school in Seattle) to learn mathematics from the Internet, which is not nearly so wrong as Discovering Mathematics. With luck, any poor grades they get in stupid reform math courses won’t count against them, and if College Board caves and reforms the SAT to correlate with grades in stupid reform math courses, there will hopefully still be pressure for them to keep the AP and SAT II tests. If everything falls apart, kids that like math can drop out of school, learn from the Internet, then make a living tutoring the hapless victims of the new reform math.
Oh, and if you ever see an elevator whose “control panel displays ‘0’ for the floor number,” when it’s at the basement, please take a photo and send it to me.

In the early 1990s, troubling portraits began to appear more often and even emerge. Here is a gallery of troubling portraits (sources: Google News Archive, Google Scholar, Google Books)
Before 1985 (3 known cases, all listed below)
1986-1994 (approx. 70 cases, examples listed below)
1995-2004 (over 100 cases, examples listed below)
2005-date (over 100 cases, examples listed below)
Recently, some portraits have been emerging but not identified as troubling, though they might be. The significance of these reports is unknown.
The earliest troubling portrait (1916) was hypothetical. A fictional character in The Girl Philippa suggested the possibility that one could be painted. He said, “I see. A man could paint a troubling portrait of her — a sermon on canvas.”

When used to modify an adjective, the English word “otherwise” means “in (all) other respects,” but it almost always highlights a contrast. For example, “A bone in my filet de dorade was the only bump—and a small one—in the otherwise excellent gastronomic journey we enjoyed at El Patagón Goloso.” The filet wasn’t perfect, but everything else was. (was / wasn’t)
Earlier this evening, I wanted a word like “otherwise” that didn’t highlight a contrast. For example, suppose El Patagón Goloso’s dorade was the best I’d ever eaten, and the rest of the meal was also excellent. After a description of the dorade, “otherwise” doesn’t work. “Otherwise, the meal was excellent” suggests that something (whatever was previously mentioned) about the meal was not excellent. The only solutions seem to me too long or a bit awkward: “In all other respects, however, the meal was excellent.” or “The meal was otherwise excellent as well.”
Stuck without a word, I made one up: “alsowise.” I think it’s useful, not only as an answer to the analogy AND:BUT::?:OTHERWISE.

Want my attention? Misspell something. Better yet, point out a misspelling with “[sic].” Even better, sicize an invasive misspelling.
Barry Petchesky sicized “miniscule” in a recent and alsowise fine Deadspin article on Paul Shirley’s Haiti fumble. Despite the fact that—as Barry put it—“Deadspin has long been [the] go-to source for professional athlete penis,” and despite the fact that Barry was on Jeopardy! last year, somehow I didn’t know Deadspin from Adam or Barry from Steve. I’m glad Barry captured my attention, and I’m happily spending this evening with him at home. Thanks, Barry!
Related forms:
sicization: the act of sicizing
sicizy: / ˈsɪ sɪ zi/ a rhetorical device, specifically, the use of sicization in order to deprecate or ridicule
I hope you’ll join me next week, when the word of the day will be intertelligible.

How big was this weekend’s really big mid-Atlantic snowstorm? So big that George Washington and Thomas Jefferson noted it in their diaries!
Really. The New York Times said so. Our founding fathers wrote in their diaries about this weekend’s storm. Awefomenefs.
This snowstorm was bigger than the U.S. Civil War, bigger than the moon landing, and bigger than Lady Gaga and Elton being on stage together last week! Geo. and Th. didn’t write about those other things, right? I mean, I spent most of the summer of ‘69 reading and would’ve seen something about the moon landing being in those guys’ diaries, I think. Yeah, Nixon was president, but still, we’d know, right?
Here’s the Times quote:
The National Weather Service said the blizzard did not challenge Washington’s 28-inch record, set in January 1922, a snowfall that collapsed the roof of the Knickerbocker Theater, killing 98 people and injuring 158. Nor did it rival the three-foot snowfall of 1772, long before record-keeping began, although it was noted in the diaries of George Washington and Thomas Jefferson.
Unless I missed something in Bits about time machines, I’m pretty darn sure the Times is wrong. Maybe they meant to write something like
The National Weather Service said the blizzard did not challenge Washington’s 28-inch record, set in January 1922, a snowfall that collapsed the roof of the Knickerbocker Theater, killing 98 people and injuring 158. Nor did it rival the three-foot snowfall of 1772, long before record-keeping began,
although itthat was noted in the diaries of George Washington and Thomas Jefferson.
or
The National Weather Service said the blizzard did not challenge Washington’s 28-inch record, set in January 1922, a snowfall that collapsed the roof of the Knickerbocker Theater, killing 98 people and injuring 158. Nor did it rival the three-foot snowfall of 1772, which occurred long before record-keeping began and was noted in the diaries of George Washington and Thomas Jefferson.
Or maybe they meant this for an audio-only story, where it would be possible to say “Nor did it rival the three-foot snowfall of 1772, long before record-keeping began, although IT was noted in the diaries of George Washington and Thomas Jefferson,” (still sloppy, but talk is a whole nother language from written) because if you say “it” very emphatically, you can intimidate it and make it change its antecedent.
And maybe I understood what they meant, too. But writers should write as precisely as possible; they shouldn’t write in the spirit of nearest-neighbor error-correcting codes and assume it’s fine to publish written nonsense assuming the reader will subconsciously refer to a Hamming distance ruler and an unabridged vector space of things that make sense and infer the right thing.
Any errors, whether regarding pronomial antecedents or otherwise, are my responsibility.

In July, I griped here about misleading news reports of a higher crash risk among texting truckers than among non-texting ones. I pointed out that the research quoted had not shown an increased crash risk, and in fact observed fewer crashes (zero, in fact) among the texting truckers. The data might suggest a decreased crash risk among texting truckers, I noted. The reason for the confusion was that crashes and near-crashes (which included sudden and possibly crash-preventing maneuvers) hadn’t been separated in the calculations. Nevertheless, the increased crash-or-near-crash risk was widely reported as an increased crash risk. I wondered whether more near crashes might in fact be a positive thing; those who occasionally swerve suddenly might be paying more attention to the road than those who rarely do.
Today, researchers and others are expressing surprise that just-in real crash data doesn’t support what they don’t realize the earlier research didn’t show in the first place. For example:
If researchers (or journalists) are surprised by today’s news, they probably didn’t examine the research very closely. They may have believed the misleading headlines instead.
Disclaimers: I haven’t read all the research, and some studies might have in fact shown an increased crash risk, unlike the one I mentioned. That might be reason for real surprise. In addition, today’s data doesn’t specifically show that less phone use means no fewer accidents, because laws don’t always change behavior. But some of the reports I read did suggest that there was less phone use, yet no lower crash rate, in places that instituted bans.
Ironically, the crash data out today could make things worse. If drivers think phone use while driving is not as unsafe as previously thought, they might be less careful when using a phone while driving, and phone-related crashes might increase. Common sense suggests that multitasking requires greater concentration. If you do use a phone while driving, drive with even more care than usual. In other words, this might be one situation where being wary might have benefits, even when its not warranted by the facts – especially because being somewhat over-cautious while driving has no serious down side, it seems to me. (It’s not like it infringes upon hundreds of millions of people’s civil rights, like acting on other unwarranted fears can and does…)

A headline in today’s Washington Post is “Fewer Americans think Obama has advanced race relations, poll shows.” My statistics students know what I have to say about that: “fewer than what?” Yes, headlines are generally false, and the Post reports the statistics somewhat more carefully in the article. “On the eve of President Obama’s inauguration a year ago, nearly six in 10 Americans said his presidency would advance cross-racial ties. Now, about four in 10 say it has done so.”
According to the actual poll results, a year ago, 60 percent of Americans answered “help” to the question “Do you think Obama’s presidency will do more to (help) or more to (hurt) race relations in this country, or not make much of a difference?” Last week, 40 percent of Americans answered “help” TO A DIFFERENT QUESTION: “Do you think Obama’s presidency has done more to (help) or more to (hurt) race relations in this country, or has it not made much of a difference?”
Big deal. Not a story. Fewer Americans today also think they have died than thought last year that they would die.

Original title: Over 90% of Research Studies Make Me Want to Scream (P < 3E-12).
Shania Twain is in the news today. No, her new album still isn’t out, but her face is in the spotlight. It turns out someone “applied” the latest “research” to “determine” that she has the perfect face, “scientifically” speaking. The distance between her eyes and mouth are precisely 36% of the length of her face, and her interocular distance is exactly 46% of its width. These proportions, according to an article in press at Vision Research, are universally optimal (among low-resolution, mostly Photoshopped images of a few white women).
Garbage. Poppycock. Nonsense. Balderdash. Crap, crap, crap of a research paper, right from sentence 1: “Humans prefer attractive faces over unattractive ones.”
But you came here for the pictures. (more…)
