No matter what new problem it sets for parents

The nursery school, therefore, appears as a counter influence against the almost hidden processes by which society through the parents undertakes the premature exploitation of children’s interests in behalf of its own conventionalized and not very natural program of life.  It thus happens that one of the first considerations in a nursery school program is that after satisfying the expectations of the family with regard to the physical care of children it should keep its further thinking in firm alignment with biological rather than social understandings with regard to the present and future welfare of the child, and this no matter what new problem it sets for parents, and no matter what amount of diversity of opinion may arise between them and the school.

(Frederick W. Ellis, introduction to Harriet M. Johnson’s Children in the Nursery School, 1928.)

i, you sneaky bastard

Childhood memory:  I learned that i is formally defined to be the square root of -1.  Well, I thought, that worked well, what about the square root of i?  Surely that must be yet a new kind of number.  I just had to check that (a+bi)^2 can never be i.  But whoa, you can solve that!  (sqrt(2)/2) + (sqrt(2)/2)i does the trick.  I was kind of bowled over by this.  i, you sneaky bastard — you anticipated my next move and got ahead of me!  I had no idea what “algebraically closed” meant, or anything like that.  But it was one of my first experience of the incredible power of the right definition.  Once the definition is right, you can just do everything.

Strawberries and Cream

I discovered yesterday, three nested directories down in my math department account, that I still had a bunch of files from my last desktop Mac, which retired in about 2003. And among those files were backups from my college Mac Plus, and among those files were backups from 3 1/4″ discs I used on the family IBM PC in the late 1980s. Which is to say I have readable text files of almost every piece of writing I produced from age 15 through about 25.

Very weird to encounter my prior self so directly. And surprising that so much of it is familiar to me, line by line. I can see, now, who I liked to rip off: Raymond Carver, a lot. Donald Barthelme. There’s one poem where I’m pretty sure I was going for “mid-80s Laurie Anderson lyrics.” Like everyone else back then I was really into worrying about nuclear war. I produced two issues of a very mild-mannered underground newspaper called “Ground Zero” with a big mushroom cloud on the front, for the purpose of which my pseudonym was “Bogus Librarian.” (I really liked Bill and Ted’s. Still do, actually.) Anyway, there’s a nuclear war story in this batch, which ends like this: “And the white fire came, and he wept no more.” Who is “he”? The President, natch.

But actually what I came here to include is the first thing I really remember writing, which is a play, called “Strawberries and Cream.”  I wrote it for Harold White’s 9th grade English class.  The first time I met Mr. White he said “Who’s your favorite author?” and I said “I don’t know, I don’t think I had one,” and he said, “Well, that’s terrible, everyone should have a favorite author,” and I probably should have felt bullied but instead felt rather adult and taken seriously.

A central element of his English class was writing imitations of writers, one in each genre.  So I wrote an imitation John Cheever story, and I think an imitation Edna St. Vincent Millay poem (I can’t find this one, tragically.) But the thing Mr. White asked me to read that really sang to me was The Bald Soprano.  Was it that obvious, from the outside, that it was mid-century Continental absurdism I was lacking?  Or was it just a lucky guess?

Anyway:  below the fold, please enjoy “Strawberries and Cream,” the imitation Eugene Ionesco play I wrote when I was 15.

  • The company that makes OldReader, the RSS reader I fled to after the sad demise of Google Reader, is from Madison!  OK, Middleton.  Still part of Silicon Isthmus.
  • I never new that Mark Alan Stamaty, one of my favorite cartoonists, did the cover of the first They Might Be Giants album.
  • Hey I keep saying this and now Allison Schrager has written an article about it for Bloomberg.  Tenure is a form of compensation.  If you think tenure is a bad way to pay teachers, and that compensation is best in the form of dollars, that’s fine; but if California pretends that the elimination of tenure isn’t a massive pay cut for teachers, they’re making a basic economic mistake.
  • New “hot hand” paper by Brett Green and Jeffrey Zweibel, about the hot hand for batters in baseball.  They say it’s there!  And they echo a point I make in the book (which I learned from Bob Wardrop) — some of the “no such thing as the hot hand” studies are way too low-power to detect a hot hand of any realistic size.
  • Matt Baker goes outside the circle of number theory and blogs about real numbers, axioms, and games.  Daring!  Matt also has a very cool new paper with Yao Wang about spanning trees as torsors for the sandpile group; but I want that to have its own blog entry once I’ve actually read it!
  • Lyndon Hardy wrote a fantasy series I adored as a kid, Master of the Five Magics.  I didn’t know that, as an undergrad, he was the mastermind of the Great Caltech Rose Bowl Hoax.  Now that is a life well spent.
  • Do you know how many players with at least 20 hits in a season have had more than half their hits be home runs?  Just two:  Mark McGwire in 2001 and Frank Thomas in 2005.

Conservative commentators on education are mad about the new AP US History standards.

The group’s president, Peter Wood, called the framework politically biased. One of his many complaints is about immigration: “Where APUSH sees ‘new migrants’ supplying ‘the economy with an important labor force,’ others with equal justification see the rapid growth of a population that displaces native-born workers from low-wage jobs and who are also heavily dependent on public services and transfer payments.”

Here’s the full text of the relevant bullet point in the standards.

The new migrants affected U.S. culture in many ways and supplied the economy with an important labor force, but they also became the focus of intense political, economic, and cultural debates.

You can decide for yourself whether the standard sweeps under the rug the fact that many people wish there were fewer immigrants.  But shouldn’t Newsweek print the whole sentence, instead of letting its readers rely on selective quotes?  Why do I have to look this stuff up myself?

Why aren’t math professors sociopaths?

Great open from Chris Hayes:

Imagine you’re a scientist in some sci-fi alternate universe, and you’ve been charged with creating a boot camp that will reliably turn normal but ambitious people into broken sociopaths more or less willing to do anything.

There are two main traits you’d want to cultivate in your recruits. The first would be terror: You’d want to ensure that the experimental subjects were kept off-­balance and insecure, always fearful that bad things would happen, that they would be humiliated or lose their position and be cast out. But at the same time, it would be crucial that you assiduously inculcate a towering sense of superiority, the belief that the project they happen to be engaged in is more important than anything and that, because of their remarkable skills and efforts, they are among the select few chosen to be a part of it. You’d want to simultaneously make them neurotically insecure and self-doubting and also filled with the conviction that they and their colleagues are smarter and better and more deserving than anyone else.

He’s writing about young investment bankers, whose lives, such as they are, are described in Kevin Roose’s new book “Young Money.”  But doesn’t this boot camp actually describe the Ph.D. experience pretty well?  And if so, why aren’t math professors sociopaths?

I can think of one reason:  in finance, the thing you are trying to do is screw over somebody else.  If you win, someone has lost.  Mathematics is different.  We’re all pushing together.  Not that there’s no competition; but it’s embedded in a fundamental consensus that we’re all on the same team.  Apparently this is enough to hold back the sociopathy, at least for most of us.

We are all Brian Conrad now

The quality of streaming conference talks has improved a ton, to the point where it’s now really worthwhile to watch them, albeit not the same as being there.  Our graduate students and I have been getting together and watching some of the talks from the soiree of the season, the MSRI perfectoid spaces conference.  This has been great and I highly recommend it.

One good thing about watching at home is that you can stop the stream whenever anybody has a question, or whenever you want to expand on a point made by the speaker!  We usually spend 90-100 minutes to watch an hour talk.  One amusing phenomenon:  when we have a question or don’t understand something, we stop and talk it out.  Then, when we start the stream again, we usually see that the speaker has also stopped, because someone in the audience has asked the same question.  This is very reassuring to the graduate students!  What’s confusing to us is invariably also confusing to someone else, even to Brian Conrad, because we decided to always presume that the unseen, unheard questioner was Brian, which is pretty safe, right?  (One time we could sort of hear the question and I’m pretty sure it was Akshay, though.)

Proof school: it’s not just for math kids anymore

A while back I complained, I hope good-naturedly, about Proof School’s self-description as “a school just for math kids.”  A little Ravi told me that the website has since been revamped, and the new version, with tagline “For kids who love math,” is much more to my liking.  The phrase “math kids” is still around, but I think it presents them (us?) as less of a separate species, and more of an tribe bound by common culture:

By “math kids” we mean children who are truly talented and passionate about math. We say we’re looking for students who are internally pulled by math, not externally pushed into it. Of course, math kids have many interests beyond math or computer science–it’s more just a term of convenience and endearment, really–not an absolute. Almost a nickname. If you know any math kids, you know what we mean. Maybe you were one, once, too.

I’m OK with this!

I will say, though, that 6 occurrences of the words “passion” or “passionate” in the FAQ is too many.

Is online education good or bad for equality?

It seems like it would obviously be good — now kids who don’t have money and don’t live near universities have, in principle, access to much of the world’s knowledge as long as they have a cheap computer and an internet connection.

But in math, I’ve heard anecdotally that this isn’t really happening.  I thought we were going to see an influx of mathematical talent, smart kids from Mississippi who couldn’t get any math past calculus from their peers, their local high school, or the public library, but who trained themselves hardcore on Art of Problem Solving or Mathematics Stack Exchange.  But I don’t think this is happening so much.  (Correct me if I’m wrong about this!)

I thought about this when I read this article about MOOCs, which says that they’re primarily used by wealthy people who already have college degrees.  What a depressing outcome that would be, if a platform meant to make elite education available free to everybody and help undo the student-loan disaster instead mostly made life easier for people whose lives are already easy, and saved money for people who already have money.

Sebastian Thrun, MOOC skeptic

The founder of Udacity no longer thinks MOOCs are the answer, says this Fast Company article.  As for me, I’ve become more optimistic about MOOCs as I’ve talked to the people at Wisconsin who are doing them, and seen what they’ve put together.

Although Thrun initially positioned his company as “free to the world and accessible everywhere,” and aimed at “people in Africa, India, and China,” the reality is that the vast majority of people who sign up for this type of class already have bachelor’s degrees, according to Andrew Kelly, the director of the Center on Higher Education Reform at the American Enterprise Institute. “The sort of simplistic suggestion that MOOCs are going to disrupt the entire education system is very premature,” he says.

I too was surprised to learn that most people who take Wisconsin’s MOOCs are 30 and up.  But that made me really happy! Right now we put a massive amount of effort into teaching things to people who are between 18 and 21, and after they leave the building, we’re done with them (except when we mail them a brochure asking for money.)  30-year-olds know a lot more about what they want to do and what they need to know than 18-year-olds do.  55-year-olds even more so, I’ll bet.  I hope we can make higher education a life-long deal.

Oh, also:

When Thrun says this, I nearly fall out of my chair. He is arguably the most famous scientist in the world

I feel like you have to be very deeply embedded in Silicon Valley culture to type this sentence.
