Colbert returns to the amazing interviews he did with Rep. Lynn Westmoreland and Rep. Robert Wexler. Only this time, it is to skewer the allegedly serious television shows that mock his.

Colbert: “But the Today Show and Good Morning America could be right. I could be asking the wrong questions. For instance, I asked U.S. Congressman Lynn Westmoreland, who proposed requiring the display of the Ten Commandments in the House and Senate chambers if he could name the Ten Commandments. What I should have asked him was this …”

Clips from other shows:
“Is it possible that tanning is addictive?”
“How long does it take you to grow that thing [a long beard]?”
“Do you really need to wait a half-hour after you eat before you go swimming?”

It’s much funnier to watch the whole thing.

bq. We received yesterday at the Rome conference permission from the world,’’ Justice Minister Haim Ramon told Israeli radio, “to continue this operation, this war, until Hezbollah won’t be located in Lebanon and until it is disarmed.’’ Mr. Ramon also raised the possibility of an expanded air assault, saying “all those now in south Lebanon are terrorists who are related in some way to Hezbollah.’’

[as with my other posts on Israel, where our past experience has been one of vicious fights between pro- and anti-Israel commenters, I’m keeping the comments section closed. I’m not happy about this either.]

Brisbane readers of CT should already be aware of the BrisScience lecture series. The speakers so far have all been from the natural sciences, but I’m talking on Monday July 31 at the Ithaca Auditorium, City Hall, on the topic “Economics: The Hopeful Science”. The general theme is that economic progress and environmental sustainability are naturally* complements rather than substitutes.

I’m sure lots of you will want to fly in for this event, but may be concerned about the associated greenhouse gas emissions. Fortunately, although Australia is not a Kyoto signatory, Australian states are getting into the carbon credit business and (for now at least) it’s surprisingly cheap to offset a long-distance flight. More details here.

*a loaded term which I’ll try to justify in the talk

As I posted over on one of my other blogs, one’s first reaction to this paper is horrified amusement that it got printed in a reasonably respectable journal. The authors are mainly from the faculty of “Maharishi University” and it’s a study of the efficacy in reducing the frequency of terrorist incidents in Israel and Lebanon of installing a group of people practising Transcendental Meditation. It is, to be honest, pretty whacky stuff, although my personal opinion is that the meditators get the best of the methodological debate which followed (really, the yogis were not pulling any statistical funny business and they did find a significant effect; it’s discussed in this rather good article on statistical methodology generally)

But really, who is in the wrong here?

I wish Daniel would post more on CT and less on the Guardian’s Comment is Free site, partly because I worry that regular CT readers may sometimes miss his pieces. Today he has “a really interesting article”:http://commentisfree.guardian.co.uk/daniel_davies/2006/07/dumping_dumping.html arguing that agricultural subsidies aren’t always bad for the global poor and, indeed, by lowering prices for Africa’s consumers, may often be good for them. That definitely goes against the conventional wisdom (both left and right) in blogdom. Definitely worth a read.

(one of these things is not like the others … )

I’m reading Paul Krugman’s _Peddling Prosperity_ which I’m enjoying a lot, both the bits that I agree with and the bits that I disagree with. But one thing struck me as a little odd.

I just finished reading Julian Betts’s essay “The Economic Theory of School Choice” in his (excellent and remarkably inexpensive) edited collection Getting Choice Right. For the most part I don’t expect to find really new ideas about school choice in what I read, so it was a thrill to find something I hadn’t encountered before. The contributors all assume (correctly in my view) that school choice is an inevitable feature of the education system, so the issue is how to get it right — in other words, how to make it as efficient and equitable as possible (self-styled opponents of school choice tend to support the de facto status quo, a school choice system riddled with inefficiencies and inequities).

The most obvious barrier to a school choice being efficient and to it being equitable is the fact that in a choice system schools get to choose students, leading, one presumes, to a concentration of advantaged students into popular schools. Defenders of choice usually offer three solutions to this problem; lotteries (preventing schools from choosing); quotas (allowing them to choose but limiting their ability to select for advantage) and weighted student funding (allowing them to choose, but giving them incentives to choose disadvantaged children, and compensating schools which get landed with high concentrations of disadvantage). (I suggest a combination of these in my proposal at the end of School Choice and Social Justice).

So what’s new in Betts’s paper?

We welcome comments from readers on posts, but you do so as guests in our private space. If your comments are blatantly racist, sexist or homophobic we may well delete them. The same goes for comments which are personally defamatory or insulting or which seek to derail a thread through provocation of one kind or another. If your comments strike us as stupid or irrelevant we may also delete them in the interests of keeping the conversation at a reasonable level. Likewise, commenters who routinely seek to make marginally relevant debating points may be barred to make room for those with a substantive contribution to the discussion. It is up to us.

We are happy to accept pseudonymous comments but we will not knowingly accept comments from individuals using more than one id and thereby giving the impression that their comments originate from more that one person. The only exception to this that is acceptable is where a person who normally comments under their own name needs to comment pseudonymously for clear professional or personal reasons. Commenters should normally provide a valid, working email address. Such addresses are only visible to members of the CT collective (and not to casual readers). Commenters who provide addresses like noone@nowhere.net may find their comments deleted without warning.

We respect the preference of many genuine commenters for pseudonymity and will protect their privacy. However, this respect does not extend to those who abuse pseudonymity to launch personal attacks on posters or other commenters, post racist or sexist comments or employ sockpuppets. We will, if appropriate, publish the identity of such abusers and share their identifying information with other sites.

In the comments to my post on Onsager, Maynard Handley explains why he finds himself somewhat unsympathetic, as Onsager apparently did not expend the effort necessary to make himself understood by others.

You, the author of the paper, have a responsibility to make your ideas comprehensible. If the first method you choose to explain them fails, then you listen to what people say about where they lost all track of understanding and write a new paper—- with NEW explanations, not the same explanations that failed last time only renumbered. … [This is] not something that is drilled into young scientists; that it is YOUR responsibility to make your ideas clear to others, not their responsibility to try to figure out what you are talking about. As science grows ever larger and ever more complex, I think it is time for all scientists to be much more explicit and much more ruthless on this point.

Whether this is really a fair criticism of Onsager, I couldn’t say, but the general point is true, important, and a perfect hook for the next thing I wanted to post about.

Cosma’s review of “Stephen Wolfram”:http://www.cscs.umich.edu/~crshalizi/reviews/wolfram/, linked to below, says that:

bq. Wolfram refers incessantly to his “discovery” that simple rules can produce complex results. Now, the word “discovery” here is legitimate, but only in a special sense. When I took pre-calculus in high school, I came up with a method for solving systems of linear equations, independent of my textbook and my teacher: I discovered it. My teacher, more patient than I would be with adolescent arrogance, gently informed me that it was a standard technique, in any book on linear algebra, called “reduction to Jordan normal form”, after the man who discovered it in the 1800s. Wolfram discovered simple rules producing complexity in just the same way that I discovered Jordan normal form.

I’m in no sense of the word a mathematician, but I too made a “discovery” in my teenage years, and found out years later that I wasn’t alone – Samuel Beckett, since we’re already talking about him, describes the technique in _Watt_. In Beckett’s words:

bq. In another place, he said, from another place, he might have told this story to its end, told the true identity of Mr Nackybal (his real name was Tisler and he lived in a room on the canal), told his method of cube-rooting in his head (he merely knew by heart the cubes of one to nine, and even this was not indispensable, and that one gives one, and two eight, and three seven, and four four, and five five, and six six, and seven three, and eight two, and nine nine, and of course nought nought).

In other words, each single digit number has an unique cube, and if you know this cube, and do a bit of memorization (e.g. that the numbers 0 to 9 have cubes between 0 and 729, that 10-20 have cubes between 1000 and 8,000, and so on), you can derive the cube roots of quite large sounding numbers very easily (as long as they’re whole numbers). For example, to figure out the cube root of 103,823, the final digit is a 3, which means that the final digit of the cube root is 7, and since 103,823 is between 64,000 (the cube of 40) and 125,000 (the cube of 50), the cube root has to be 47.

I’m presuming that if this trick occurred to me and Beckett independently, it must be common knowledge, but haven’t seen it written up anywhere else. I’d be curious to know if someone else (Martin Gardner???) has described it.

A staple of bad movies and trashy novels about scientists (i.e., the kind I read) is the neglected genius whose ideas are rejected with incomprehension by the scientific establishment during his life, because they are simply Too Far Ahead Of His Time to be grasped by lesser mortals, only for the scientific community to rediscover these insights decades later. This sort of thing can make for entertaining fiction (if dreary self-mythologization), but it simply doesn’t happen all that often in real life, especially not when the hero is a part of the establishment, and indeed a much-honored one. It certainly doesn’t show up, with documentary evidence, in the staid, reliable pages of Reviews of Modern Physics. Nonetheless:

Two of my more public-spirited fellow citizens have recently identified looming threats to our own Commonwealth of Pennsylvania.

1. Our beloved junior senator, Rick Santorum (via Pharyngula):
   

   Most scientists unfortunately, those that certainly are advocating for this [embryonic stem cell research], and many others feel very little moral compulsion. It’s a utilitarian, materialistic view of doing whatever they can do to pursue their desired goals.

   I, for one, will be happier voting on Mr. Santorum’s re-election in November, knowing that my ballot will play a part in the age-old struggle between utilitarian materialism and deontological idealism, as well as the sagas of human-canine relations and Old Corruption.

2. Our beloved linguistics professor, Mark Liberman:
   

   More than a third of all Pennsylvanians are native speakers of a language other than English — and many of them have not even tried to learn English since immigrating, or at least prefer to carry out their daily lives in another language, living together in neighborhoods where their native language dominates. Some people worry that the majority status of English is critically endangered. 25 years ago, a major political figure warned that these “aliens … will never adopt our language or customs, any more than they can acquire our complexion”, and so far, his prediction seems to be right on the money.

   And let’s not forget what they’ve done to our cooking!

Le Blog Bérubé “last Friday”:http://www.michaelberube.com/index.php/weblog/abf_friday_bonus_edition/

bq. I will therefore postpone the next installment of Irish Blogging (Beckett’s _Murphy_ is on tap for Monday) and devote the day to promiscuous linkdumping and an installment of our ever-popular Arbitrary but Fun stuff.

Le Blog Bérubé “yesterday”:http://www.michaelberube.com/index.php/weblog/thanks_for_the_memories/

bq. Today was supposed to be Beckett Day on this blog, but we interrupt our brief foray into Irish Literature Blogging to bring you this important Lieberman Bulletin.

I think we’re beginning to get the joke …

Update: and “today”:http://www.michaelberube.com/index.php/weblog/blogging/

bq. One more thing while I’m working away on my Beckett post (which I will begin writing real soon, I promise).

Under the rubric “Can Blogging Derail Your Career?”, the Chronicle of Higher Education has seven bloggers discussing Yale’s decision to not hire Juan Cole as a professor of history, and the role, if any, played by his blog in that decision: Siva Vaidhyanathan, Dan Drezner, Brad DeLong, Michael Bérubé (all: yay!), Glenn Reynolds and Ann Althouse (both: hiss), and Erin O’Connor (null result), with a “response” by Cole, which doesn’t actually address the others’ posts specifically, and reads like a separate essay on the same subject as the others. (Via DeLong.)

(Some of the things which were written about Cole as part of the controversy (e.g.,) give the impression of a professor who attains incomprehensibility not through obscurity but through foaming at the mouth. As it happens, though, I sat in on his seminar on millenarian movements when I was a post-doc at Michigan, and nothing could be further from the truth. I suppose I could have missed all the sessions which degenerated into hours-long rants about Zionist Entities… Of course, I don’t know why Yale didn’t give him the job, but if it was because they thought he was too spittle-flecked to be presentable to parents and alumni, they were misinformed.)

The fact that this post is not filed under “Middle East Politics” isn’t going to stop anyone in the comments, is it?
