In the Woods
It’s also a total pleasure to be captivated by the gorgeously poetic language of Tana French, whom I don’t otherwise know as an author. The heightened intensity of her words couldn’t possibly continue for 21 hours, and of course it doesn’t, but quite a number of passages read more like poetry than prose. All of this occurs in the context of a novel that looks like a police procedural but isn’t really. It’s actually a psychological novel about introspection, the effect of early experiences, and interactions among well-developed characters. Some reviews have missed the point and have criticized French for not following all the conventions of the mystery genre. But it’s unfair to criticize her for not writing a different book! In the Woods doesn’t follow the mystery genre because it’s not a genre novel. Like a number of other examples of serious literature, it adopts the framework of a police procedural but has an entirely different program. I don’t want to reveal any of the details other than to say that the narrative takes place within a homicide squad of a modern Irish police department. Definitely read it — but don’t expect everything to be nicely tied up at the end as you would anticipate in a conventional mystery!

Salt of the earth
For our first course, Barbara had giant white prawns, which came with spinach, creamy polenta, bacon, and greens. She reports that it was all delicious, as long as she could ignore the fact that the prawns came with their heads on. I had flatbread pizza with caramelized onions, spinach, lamb bacon (!), Comté cheese, fried capers, and créme fraiche. It sounds overly elaborate, but all the flavors melted seamlessly together to create an excellent dish.
Barbara then had steak frites with asparagus, cooked perfectly and very French. My main dish was described as follows on the menu:
Braised lamb shank with spring bean cassoulet, merguez, caramelized rhubarb and sweet onion compote.I’m not sure how much merguez there was, but everything else was there in perfect balance — a great combination.
The service was wonderful. Perfect, you might say. The waitress was friendly without being intrusive, knowledgeable but never pretentious, and attentive without hovering.
Not surprisingly, we had no room for dessert and both of us even had leftovers to take home. I suppose it was worth the $200 for a once-a-year (or perhaps twice-a-year) experience.

Technology in school
Cell Phones, I-Pods, MP3 players, any other electronic devices are not permitted for student use at any point during the school day. If these items are seen or heard during school hours, they will be confiscated and a parent will have to pick up the device from your child’s house office.This seems pretty reasonable, especially since the careful wording doesn’t prohibit possession of such devices, merely their use or visibility during the school day. And, of course, it is a middle school.
Heather’s post includes the following observations:
Is there ever a circumstance in which the presence and use of an iPod (or cell phone or MP3 player or digital camera or gameboy or fill-in-your-electronic-device-of-choice-here) is justifiable in a school setting? I guess I’m taking the perspective of the teacher on this one. There is nothing more annoying than someone’s cell phone going off during a lecture. And there is nothing more rampant in university settings than “creative” new ways to cheat during examinations. I can’t believe that the use of electronics for cheating begins at the college level.These are eminently reasonable comments, but I need to take a different point of view, even though Heather is trying to take the perspective of the teacher. Of course she’s absolutely right that it is annoying and disruptive for a cell phone to ring during class, and she is also absolutely right that they need to be prohibited during tests, as they can be used for cheating (as Weston students know all too well). But there are also too many valuable uses of these electronic devices for them to be banned entirely in school — at least in high school, and I suspect in middle school as well. At Weston High School we ban cell phone use (or even visibility) in the classroom, but not in the cafeteria or outdoor areas; iPod use is left to the discretion of the teacher. Cell phones are a valuable way for students and parents to get in touch with each other, so students should be allowed to use them outside of the classrooom. And MP3 players may help many kids concentrate in noisy situations or just when taking a test; while I certainly don’t allow kids to shut out the world during a class discussion or lecture, I think it can be valuable to do so when trying to concentrate on individual work. I admit that there’s a small chance that a student may use an iPod for cheating, but that’s a lot harder than texting on a cell phone, which is currently the preferred method among high-school students and Boston firefighters. Of course a variant of the method used by the firefighters would be very difficult to prevent in school settings:
My understanding on the ban of cell phones in public schools was that it was originally put in place to prevent drug deals going down on the school premises. But now cell phones could be used for anything from covertly cheating by sending text messages to voyeuristic photography in the ladies room to remotely setting off bombs. I won’t waste my space here, but we need only use of imagination to think of the ills of other electronics in the school settings. Nintendo DS’s create their own network within a local range.
...a group of Boston firefighters took turns going into a men’s room at the Quincy middle school and sent answers via text message on their cellphones to colleagues in the testing room.We can easily prevent this precise method of cheating in school by allowing only one student at a time to go to the bathroom and by banning cell phone use in the classroom during the test, but how do we prevent texting between a student who goes to the bathroom during the test and a classmate who has already taken the test and is currently in the cafeteria during a free period? Temporarily confiscating cell phones at the beginning of the test is the method preferred by some teachers. That works well...except for kids who have a second cell phone hidden away.
And while I’m looking at Heather’s blog, let me recommend several of her recent posts, especially the ones entitled “Wow” and “What would Jesus do, indeed”.

Where can Dorchester kids get into college?
Some of my Weston students believe that they are entitled to go to Harvard and BC and Bryn Mawr, but kids who go to public schools in Dorchester and Roxbury certainly aren't in their league. If your parents are rich and well-connected and have provided you with every educational opportunity that money can buy, you deserve to get into Harvard, don't you? But if your parents are low-income immigrants who have sent you to the school formerly known as Dorchester High School, you don't have a chance.
Or do you? Well, admittedly the deck is stacked against you; the odds are in favor of the Weston student. But let's look at some of the 29 high-school seniors who have been attending the Crimson Summer Academy for the last two summers, starting with some of the most competitive colleges:
- Harvard admitted 3. That’s 10% of the class — can’t beat that at Weston.
- Smith admitted an astounding 5 of the 15 girls!
- BC admitted 3.
- MIT admitted 1!
- Brandeis admitted 1, Bryn Mawr 2, Johns Hopkins 1, Penn 1, Pitt 1, Syracuse 6, Union 2, Wellesley 1, Wesleyan 1; Barnard put 2 on their wait-list.
- Some of the remaining six may also be highly competitive schools (I just don’t know about all of them): Denison admitted 1, Lehigh 3, Mass Art 1, Northeastern 8, Regis 3, and Wheaton 3.

Money talks in Weston
“That can’t be true!” objected one student. “Bill Gates is the smartest living American!”
“What makes you think that?” I asked, being genuinely puzzled.
“Because he’s a billionaire,” replied one student. “He’s the richest man in the country,” said another. Several others chimed in with similar sentiments.
I told them that they had been living in Weston too long.

Death Comes for the Fat Man
Anyway, you should probably have read some of the earlier books in the series before tackling this police procedural, but that’s OK: if you’ve never read any Dalziel-Pascoe, go to the library and read some of the earlier ones! Then you’ll be ready for Death Comes for the Fat Man. But be sure to have a dictionary at your side as you read them, so you won’t be caught short by words like sempiternal. Every Reginald Hill novel is good for learning a few new vocabulary words. Of course they’re also good for plot and characterization, which are the real reasons to read them.

All-Dorchester seder
Like many other worthwhile all-volunteer activities, the All-Dorchester Seder needs more publicity. I give the volunteers full credit for their hard work and accomplishments, but there really should have been more than 38 of us at this event. Religiously it was a good mix — about half of the people sitting near me being Jewish — but racially it was hardly representative of today’s Dorchester, since almost everyone there was white.

Pirates in Weston
This morning I had to consult two of the most treasured volumes in my home library: Isaac Asimov’s Annotated Gilbert and Sullivan and Martyn Green’s Treasury of Gilbert and Sullivan (an appropriate name for a treasured volume). Both works are highly recommended. Concerning the “orphan/often” puns, Asimov comments that “even the most devoted pun lover might feel a little uneasy at this sequence, and parts of it are sometimes cut in actual performances.” But fortunately nothing was cut from this sequence in the Weston performance.
Alex Engler brought down the house in his flawless, very rapid rendition of the famous Major General’s patter song. A second patter song was added, presumably because this format is such a favorite with audiences: the song from Ruddigore, “My eyes are fully open to my awful situation,” was inserted, slightly changed with substitutions such as Frederic for Roderic. Asimov comments on this song:
This is the fastest of the patter songs... Gilbert was an absolute fiend on having his words heard through and above the music (which must have bothered Sullivan who felt his music was being sacrificed to Gilbert’s words), so it must have cost the librettist a deal to indicate that in this song, at least, hearing the words was all but impossible.Asimov is referring to the couplet, “This particularly rapid, unintelligible patter/ Isn’t generally heard, and if it is it doesn’t matter!”
And speaking of the Major General’s song, we math teachers always enjoy the various allusions to mathematics in it:
I’m very well acquainted, too, with matters mathematicalA few other random observations:
I understand equations, both the simple and quadratical
About binomial theorem I am teeming with a lot o’ news [pause to think]
With many cheerful facts about the square of the hypotenuse.
I’m very good at integral and differential calculus
...
In conics I can floor peculiarities parabolous...
- I am not sure why Ruth wasn’t made up to look older and less attractive, as Gilbert makes a point of contrasting her with the General’s daughters.
- Speaking of daughters, I’m not sure why they got changed into General Stanley’s wards.
- Asimov observes that Frederic’s 21st “birthday” wouldn’t actually come until 1944 rather than 1940 as Gilbert claims, since 1900 hadn’t been (wouldn’t be) a leap year! (This is true, despite the fact that the New York Times apparently printed an editorial on February 29, 1940, entitled “Frederic’s out of his indentures.”)
- As is traditional in G&S, a number of small changes were made to enhance the performance, such as looking up into the sky and “estimating” the time as 11:38 (11:30 in the original) — again something especially amusing to math teachers.

An evening in Jamaica Plain

The works of Kevin van Aelst were also vividly related to what we’ve been studying, as his Dragon Curve, Sierpinski Arrowhead (made of Triscuits!), and Cantor Set made out of a fractal egg all show:

I was also intrigued by the works of Keith Peters, which could readily be modeled in NetLogo or StarLogo, even though he apparently used neither, and also by the works of J. Michael James, whose fractal condor was especially beautiful as it swooped around on a large screen.
All in all, definitely a worthwhile experience. I just wish the exhibit had been more extensive, so that I could have justified recommending it to my Weston students. Barbara and I spent 45 minutes there, but I think most of my students would feel done with it after 20 — hardly worth the trip from Weston. But it would be worth the trip from Dorchester, even if we hadn’t already been in JP (where Barbara works).
Anyway, after visiting the gallery, we walked to Cafe D, where we had a pleasant and delicious dinner. Crispy calamari followed by a fish taco and salad for Barbara; arancini followed by duck confit with a cassoulet of braised white beans, portabella mushrooms, and pancetta for me. With wine, tax, and tip, it all came to just under a hundred dollars, which seems to be par for the course these days. It might or might not be worth the trip from Dorchester (on the edge, in my judgment), but, as I said, we were there anyway.

N is a Number
So now I’ve watched it, with help from Netflix, which coincidentally delivered the DVD on Erdős’s birthday! This really was a genuine coincidence, since I had put it in my queue a couple of months ago with no idea when it would rise to #1. Anyway, Kelly knows that I certainly intend no disrespect toward her when I point out that of course she was exaggerating; N is a Number isn’t quite the “best movie ever.” It isn’t even even the best documentary ever. But it’s definitely a well-made, captivating documentary that should be watched by every math teacher, math student, and mathematician. It becomes totally clear that Erdős meets Paul Graham’s criteria that I discussed two days ago: absolute honesty and caring obsessively about his work.
Erdős, who died 12 years ago at age 83, was one of the greatest mathematicians of the 20th Century and certainly the most prolific; he is best known for his peripatetic life style, having had no fixed abode and collaborating extensively with hundreds of other mathematicians wherever he traveled. The movie is successful at vividly letting the viewer know the kind of person Erdős was, portraying him in person and through the eyes of his collaborators. Fortunately the filmmakers were willing to use subtitles extensively, since the accents of various Hungarian mathematicians (and others) could get in the way of ready understanding, even though almost everyone in the documentary was speaking English. As a math teacher, I thought there was a bit too much of an emphasis on anecdotes, but that’s a small cavil; I use anecdotes myself in similar ways, and I recognize that it’s the best way for the film to appeal to a general audience, who wouldn’t want to watch or listen to lots of mathematics.
I want to quote a couple of snippets out of N is a Number. One comes from Ron Graham — another Graham! but no relation to the aforementioned Paul Graham, as far as I know — who has a major role in the movie:
When mathematics appears in print, it’s theorem, proof, theorem, proof, but when we’re doing math it’s a completely different thing. It’s three or four people sitting around with cups of coffee, a pad of paper, throwing ideas back and forth, making a lot of conjectures, most of which turn out to be completely false.That’s what should happen from time to time in our math classes, but it almost never does, even at Weston, except in last year’s Friday-afternoon optional after-school math get-togethers.
The other snippet comes from Erdős himself:
We’re trying to read the pages of The Book. We don’t create mathematics, we’re just trying to read the pages of The Book.How Platonist can you get? This is clearly the right attitude toward the mathematical endeavor!

Heroes
I’m not claiming this is a list of the n most admirable people. Who could make such a list, even if they wanted to?I had never thought of that criterion before, but perhaps it would unstick me. Then I thought of the statement from one of my former students that Paul Erdős is her hero. [Brief aside: it’s tough to get the correct diacritic over that o. The natural tendency is to try for an unlaut — Erdös — especially since umlauts are relatively easy in HTML. But in Hungarian the diacritic looks like a double acute accent rather than an umlaut, producing a character with Unicode ID 0151. Thus you want “” followed by “x0151;” in HTML. End of aside.] So I wondered whether Erdős would fit the description in Graham’s next paragraph:
...
When I thought about what it meant to call someone a hero, it meant I’d decide what to do by asking what they’d do in the same situation. That’s a stricter standard than admiration.
After I made the list, I looked to see if there was a pattern, and there was, a very clear one. Everyone on the list had two qualities: they cared almost excessively about their work, and they were absolutely honest. By honest I don’t mean trustworthy so much as that they never pander: they never say or do something because that’s what the audience wants. They are all fundamentally subversive for this reason, though they conceal it to varying degrees.More on Erdős after I watch the movie about him. But note that Graham’s characterization is not a definition of “hero”; it’s simply a comment on two of their properties. Graham’s twelve heroes are Jack Lambert, Kenneth Clark, Larry Mihalko, Leonardo da Vinci, Robert Morris, P.G. Wodehouse, Alexander Calder, Jane Austen, John McCarthy, the Spitfire, Steve Jobs, and Isaac Newton. Could I make a similar list (though surely not duplicating any of Graham’s)?
I don’t think so.
But it did make me think about the issue. Which people have influenced me to such an extent that I would consider them to be my heroes? Would I really “decide what to do by asking what they’d do in the same situation”? Would my list consist of people who “cared almost excessively about their work” and “were absolutely honest”?
I suppose Isaac Asimov, Socrates, Charles Darwin, and Bertrand Russell would come to mind first. And maybe Johann Sebastian Bach. And probably Martin Gardner and Noam Chomsky. And it’s a cliché to put one’s mother and father on such a list, but it’s a cliché for a reason, so I will do that as well. And shouldn’t Shakespeare and Ibsen be on the list? And perhaps James Joyce? Well, that’s twelve, but I’m not convinced. This bears more thought...

21
Now they’ve gone and made a movie of it, 21. The plot outline on IMDb asserts that the movie is a “fact-based story,” But Drake Bennett’s article about it in the Boston Globe has this comment on the original book:
Bringing Down the House is not a work of “nonfiction” in any meaningful sense of the word. Instead of describing events as they happened, Mezrich appears to have worked more as a collage artist, drawing some facts from interviews, inventing certain others, and then recombining these into novel scenes that didn’t happen and characters who never lived. The result is a crowd-pleasing story, eagerly marketed by his publishers as true — but which several of the students who participated say is embellished beyond recognition.I haven’t seen the movie yet, but the Globe article certainly makes me skeptical. Read the article, not the book.

Math is hard, let’s go shopping, says Barbie (and others)
So, yesterday I stopped at the Trader Joe’s in Cambridge on the way home, and I happened to get a chatty cashier. She asked me what I do for a living, and I told her I’m a high-school math teacher. Needless to say, I expected to hear the familiar reply: “I never was any good at math.” Sure enough, that’s pretty much what she said. (Actually, it was a bit more complicated. She told me that she did well in geometry but never understood algebra. Except for geometry she did poorly in both high-school and college math because she could never deal with formulas. But now she’s an artist... well, you don’t want to know the whole story, but the key line is that she finally realized that math and art are actually a lot more alike than she had ever guessed, since “math and art are both about patterns and relationships.” Yes!)
And then this afternoon I got a phone call from my dental hygienist who told me that we needed to change my appointment because she has to take four weeks off to study for retaking her dental school admission exams, since she failed the math portion. “I never was any good at math.” Sigh. As Jerry P. King put it, “There will come a time when mathematical ignorance, like public smoking, will become socially unacceptable.” But for now for some reason it’s acceptable to admit inability to do math but not inability to read.
P.S.: Speaking of Trader Joe’s, there are 16 Trader Joe’s in Masssachusetts, so why isn’t there one in Dorchester? The demographics are right. Pass the word to the Trader Joe’s management!

The Big Nap
Anyway, the most interesting aspect of The Big Nap is the interactions between the mainstream-Jewish protagonist and members of the Orthodox Jewish community in Los Angeles, especially the Hasidic subculture. As happens when reading many good works of fiction, I learned a lot from this novel (though I believe that the Verbover branch of Hasidism is an invention of Waldman and/or her husband, Michael Chabon, since I can find no references to it outside of their respective novels). While The Big Nap is still a light novel, it definitely has more heft than its predecessor and I found it worth reading. Maybe it would have meant still more to me if I had ever had the experience of being a mother, but (un)fortunately I haven’t. Nevertheless, I still recommend it to fellow non-mothers if you want an easy-to-read detective novel with a multicultural Jewish theme.
By the way, the significance of the title’s apparent allusion to Raymond Chandler’s The Big Sleep (or perhaps it’s to the movies made from the Chandler novel) escapes me. Maybe it would help if I read the book or saw the film...

Career Day
We started with a plenary session in which Alec Sulkin delivered the keynote address and Odds Bodkin provided entertainment. Actually, and fittingly, the keynote address was definitely entertaining as well as being educational, and the entertainment also had an educational component. Sulkin is a writer and supervising producer for Family Guy, so it came as no surprise that his talk was both engaging and amusing. Bodkin is a musical story-teller who is great at what he does, but unfortunately what he does isn’t a great match for a teenage audience. Sulkin’s talk, not surprisingly, is just right for a teenage audience — at least in their eyes. Adults may disagree.
Anyway, after the plenary, we split up into a couple of hundred breakout sessions. (As I say, the organization of this event was a staggering achievement.) Each student was assigned to four out of five sessions (to allow time for lunch); they made selections ahead of time, and they got their choices except if a session was full and the student had neglected to select alternates. If you read the descriptions of the speakers, you will see the huge variety offered. Here are excerpts, with one description randomly chosen from each of the five umbrella areas:
- The Arts
- When she was 25, Hilary Price was the youngest woman ever to have a syndicated daily comic strip. Her strip, Rhymes With Orange, appears in 150 newspapers internationally, and locally in The Boston Globe. Rhymes With Orange won Best Cartoon Panel last year from The National Cartoonists’ Society.
- Business
- This speaker is currently in marketing/sales of high tech multiplexers, routers, WAN, LAN and IP Telephony. But, it’s the way he got there that matters. He has been a substitute high school teacher, worked for a private detective, in a textile mill in Maine, in a furniture store and a phone company and owned a bar. This speaker will give you perspective that there are many opportunities for you, not just one path to success.
- Crafts
- What is it like to work on innovative product development for iTunes, iPods or the present Macintosh product line? What does it take to be part of a company that encourages employees to spin off other companies and lead with innovation? This speaker, an account manager in the higher education channel, will discuss the variety of jobs at Apple Computer including sales, marketing, product development and technical support in the field. Discussion on Campus Rep jobs that are also available when you attend college so you can get an early look at life working at Apple will also be presented.
- Science
- Jill Downing is a cardiologist who practices at Boston Medical Center in Boston's South End. She is interested in preventive cardiology which involves working with patients to identify and modify heart disease risk factors. Currently she spends her time with clinical research at BMC. Her career in health care began as a registered nurse working in such diverse settings as Honduras, the Dominican Republic, and Boston. Her experience highlights some of the challenges faced by the aspiring medical professional in terms of balancing career and family demands.
- Social Services
- Alan Solomont has been a community organizer and an entrepreneur. He is a veteran of six presidential campaigns and teaches a college course on the American presidency. He is a philanthropist and trained to be a registered nurse. He is proof that a career need not follow a straight line, and that there are many ways to make a difference.

Which is more important, sports or academics? And what about the arts?
But take a look at the pages where schools are mentioned in the newspaper. It’s almost all because of sports. (OK, there’s also crime, but let’s not go there.) Even in Massachusetts it’s really a joke to expect the same kind of coverage for the math team as the paper gives to the football team (or, in the case of Weston, as it gives to the swimming and golf teams). Yes, yes, I know that participating in an athletic team can build all sorts of virtues, from persistence and cooperation to sportsmanship and planning, but it’s still not what the mission of a school is all about.
And then we get to the arts. Weston has first-rate theater and music programs, an excellent Art Department, a very successful dance team, but what kind of coverage do they get? I was reminded of this issue in a post by Adam Gaffin in this morning’s Universal Hub:
Writing on the Herald site, Tai Irwin contrasts the Globe’s coverage of the Massachusetts High School Drama Guild Finals — which it sponsored — with its Sunday coverage of high-school athletes. The final tally:The excerpt from Tai Irwin is telling:
Athletes: 16 pages of coverage.
Drama kids: Zero.
... The message is very clear: although Westford, Nauset, and Weston received awards, and many students were singled out for theatrical excellence, once again it’s sports that matter most, even to the exclusion of intellectual and artistic activities. What a great thing to tell our kids, over and over again. Never mind the brain pursuits — the science fairs and business/educational coops, and never mind the arts, dance, music, drama. The thing that is going to solve all our problems and nurture all our values best is sports. ...I couldn’t say it any better myself. So I won’t try.

Crazy Chinese words?
“What good does it do to put a Chinese story in an English book?” he said. “You learn all these Chinese words, OK. That’s not going to help you master... English. So you really don’t want Chinese books with a bunch of crazy Chinese words in them. Why should you take a child’s time trying to learn a word that they’ll never ever use again?”Oh, well, it’s Texas. Weston is much too enlightened for such attitudes. We take our global perspectives seriously, as you can see from the list of current projects, which include Giant Chinese Dragons & Lions, Uganda Professional Development Project, Columbian Exchange, Rhythm Kids: An African Drumming Experience, and Bringing the Art Experience of Ecuador into the Classroom.
He added that some words — such as chow mein — might be useful.

What's the matter with math today?
If I had to design a mechanism for the express purpose of destroying a child’s natural curiosity and love of pattern-making, I couldn’t possibly do as good a job as is currently being done — I simply wouldn’t have the imagination to come up with crushing ideas that constitute contemporary mathematics education.This sentence comes from “A Mathematician’s Lament,” an essay by Paul Lockhart, a professional mathematician. The link to this essay was found in Keith Devlin’s regular column in MAA Online, a publication of the Mathematical Association of America. (Devlin is best known for his radio columns, Saturday mornings on NPR’s Weekend Edition, and is less well-known as the author of The Numbers behind Numb3rs, which will be the topic of another post in this blog. But I don’t want to discuss Devlin here; I want to discuss Lockhart.)
Every math student, every parent of a math student, every curriculum developer, and especially every math teacher should read Lockhart’s essay. It’s not that it’s perfect, for of course it has many flaws, but its point of view is so provocatively on target that it will provide essential fodder for critical discussions. It zeroes right in what’s important in mathematics and on the misplaced emphasis of the way it’s taught in school (or skool, as my friend Brian would write):
I’m not complaining about the presence of facts and formulas in our mathematics classes, I’m complaining about the lack of mathematics in our mathematics classes.I could keep quoting thought-provoking excerpts, but I’m not going to do so; just read Lockhart’s essay yourself!
If your art teacher were to tell you that painting is all about filling in numbered regions, you would know that something was wrong. The culture informs you — there are museums and galleries, as well as the art in your own home. Painting is well understood by society as a medium of human expression... But if your math teacher gives you the impression, either expressly or by default, that mathematics is about formulas and definitions and memorizing algorithms, who will set you straight?
But wait! I can’t resist quoting his “completely honest” course description for the typical Algebra II course as taught in American high schools:
The subject of this course is the unmotivated and inappropriate use of coordinate geometry. Conic sections are introduced in a coordinate framework so as to avoid the aesthetic simplicity of cones and their sections. Students will learn to rewrite quadratic forms in a variety of standard formats for no reason whatsoever. Exponential and logarithmic functions are also introduced in Algebra II, despite not being algebraic objects, simply because they have to be stuck in somewhere, apparently. The name of the course is chosen to reinforce the ladder mythology.Fortunately things aren’t quite this bad at Weston. But it’s still painfully close to the truth. Solutions, anyone?

“You’ll enjoy the same success and happiness...”
The thrust of the essay was an attempt to reduce college admissions anxiety by pointing out that your future is not determined by where you go to college. You are just as likely to be successful and happy if you go to your local state college as you will be if you go to Yale. That bit may be true, although it’s very hard to tease out the statistics, since of course we’re not talking about equivalent populations. Let’s look at some excerpts:
...My mission today is to celebrate the safety over the reach, to say to high school seniors, “You who are waiting anxiously for that fat envelope, please know that you’ll enjoy the same success and happiness whether you end up at Bates, Bowdoin, or Ball State.”So how would this essay go over in a town like Weston? I suppose I should simply ask some of my high-achieving juniors to read it, and we’ll see what they say. As a graduate of Lowell High School and Simmons College, the undeniably successful Lipman must know what she’s talking about, but my prediction is that her essay won’t be persuasive. She makes some fine points, but...I’m not convinced. I wish I could agree with it.
When I was 20 an older friend predicted, “Ten years from now, no one will care where you went to school. In fact, no one will ask.” Ridiculous, I thought. She turned out to be right. Where you live between the ages of 18 and 22 won't define who you are. One day soon, the proud new college decal on your family car’s rear window will start looking a little uncool.
...
In 1987, a friend’s son wrote to admissions officers explaining that he had fallen in love and was therefore distracted, so could they please excuse the C in physics? They did. He went to Yale. If he hadn’t? I daresay he would be the same hero he is today, getting the wrongly convicted out of prisons through the Innocence Project.
...
If I ruled this new admissions universe, I would study the applications and sniff out the resume padders whose parents could afford the semester in the rain forests. I’d want good smart kids, including the ones who didn’t shine as brightly as the alleged stars at this moment in their high school lives... Maybe I would go with the lottery, or maybe just take the first 1,000 who applied. Studies would have shown that you are all excellent, and in the end, I couldn’t go wrong.

MCASitis
Speaking of which, take a look at pediatrician Dr. Gwenn’s article on MCASitis (thanks to Adam Gaffin’s Universal Hub for the link). Here is an excerpt:
Yesterday I saw a young girl in my office who had very bad tummy aches... Chatting with this young, pleasant child and her mom I learned she’s in third grade in a town near mine and facing the dreaded MCAS testing today — our State’s standardized testing that starts in third grade and goes all the way through tenth. Out of the blue she said, “I’m scared of the MCAS — my teachers told me that the graders are tough and we have to watch how we answer the written answer.”But of course it’s supposed to ensure that no child is left behind.
Now I had my answer. This young girl had what I have come to call “MCASitis”...a form of performance anxiety brought on every Spring here in Massachusetts. You likely have a similar form in your State.
Test taking anxiety is truly real, even for young kids. And, with anxiety can come physical symptoms such as stomach aches.

Wellness Day
“Professional development”: what thoughts does that phrase conjure up? FWIW, let’s see what Wikipedia has to say:
Professional development often refers to verbal and tactile skills required for maintaining a specific career path or to general skills offered through continuing education, including the more general skills area of personal development. It can be seen as training to keep current with changing technology and practices in a profession or in the concept of lifelong learning.Actually, that’s not bad, except for the bizarre reference to “verbal and tactile skills” in the first clause. The Commonwealth of Massachusetts appropriately requires all teachers to participate in professional development every year, and the town of Weston offers us a wide variety of opportunities, ranging from required curriculum-based seminars to optional workshops in the summer. Once a year we have Wellness Day.
So, what is it that makes me uncomfortable about this? I do recognize that all employers have a legitimate interest in keeping their employees healthy and productive. And I do recognize that a Wellness Day can be useful, fun, and intellectually stimulating. And I do recognize that it could also be an opportunity for community-building. Yet somehow it doesn’t add up for me. At least it doesn’t add up to professional development. Not to my eyes, at any rate.
And what, you ask, did I do today? We had some required activities, plus one session where there was a one-out-of-four choice, and two sesions where there was a one-out-of-many choice. During the day I participated in a “dumb game,” I listened to a very worthwhile presentation on bullying from a representative of the Middlesex County District Attorney’s office [!], I had lunch with my colleagues (a lovely make-your-own-fajitas meal organized and paid for by the PTO and prepared by the Administrative Council), I attended a session that showed a couple of movies about first aid, and I went on a long walk. I could have gone on the walk on my own, not on school time, but at least this way I got to have an extended one-on-one conversation with the drama teacher/theater director. I enjoyed that a lot, since I rarely get more than five minutes with him.
In fact, I enjoyed the whole day. But I’m still not convinced that it’s professional development.

Which comes first, the movie or the book?
In standard mathematical fashion, let’s see whether we can abstract from the concrete example of one movie/book pairing to the more general case. What happens with other such pairs? Sometimes the order doesn’t matter. And often I read a book as soon as it comes out and then have to wait for the movie, so the order is imposed artificially. What are the consequences of reading the book first? On the plus side, you have the freedom to visualize characters and scenes as you wish, and you can learn the necessary background that might be omitted from the movie. On the minus side, the movie is usually a disappointment, precisely because it can’t possibly capture everything in the book. Furthermore, my own view is that surprises and plot twists in a movie are more effective when one hasn’t read the book first. There are surely exceptions, but on the whole I come down on the side of always reading a book after seeing the movie wherever possible.

Mozart and the Whale: The book
The only real problem with the book is that the first-person point of view changes without warning from section to section. Presumably Dodd interviewed the Newports extensively and fashioned the narrative out of their information with an attempt to capture their separate voices. But apparently he isn’t skilled enough to succeed at this endeavor, since it’s often impossible to tell who’s speaking except from external clues (like mentioning the spouse). Of course this makes me wonder whether he is actually capturing the voice of either Newport; probably what’s coming across is Dodd’s voice.

Goodbye, Arthur C. Clarke.
I particularly remember Clarke’s observation that “any sufficiently advanced technology is indistinguishable from magic,” as well as his agreement with the late, lamented Isaac Asimov that each would refer to himself as “the world’s second best science fiction writer.” As Asimov wrote in his autobiography:
Arthur Charles Clarke was born toward the end of 1917 in Great Britain. He is another science fiction writer who has been thoroughly educated in science and he did extremely well in physics and mathematics.Both Clarke and Asimov were science-based writers of science fiction; neither was a prose stylist, but both of them stuck to a transparent style that let the content of their writing shine through with great clarity.
He and I are now widely known as the Big Two of science fiction. Until early 1988, as I’ve said, people spoke of the Big Three, but then Arthur fashioned a little human figurine of wax and with a long pin.
At least, he has told me this. Perhaps he’s trying to warn me. I have made it quite plain to him, however, that if he were to find himself the Big One, he would be very lonely. At the thought of that, he was affected to the point of tears, so I think I’m safe.
I’m very fond of Arthur, and have been for forty years. We came to an agreement many years ago in a taxi which, at the time, was moving south on Park Avenue, so it is called the Treaty of Park Avenue. By it, I have agreed to maintain, on questioning, that Arthur is the best science fiction writer in the world, though I am also allowed to say, if questioned assiduously, that I am breathing down his neck as we run. In return, Arthur has agreed to insist, forever, that I am the best science writer in the world. He must say it, whether he believes it or not.
I don’t know if he gets credited for my stuff, but I am frequently blamed for his. People have a tendency to confuse us because we both write cerebral stories in which scientific ideas are more important than action.

Don’t procrastinate!
Goodbye, George, I hardly knew you.
P.S.: I have just been told about the Globe’s article on George Sanborn. Read that too.
