One faculty member — she's always tough on me, but she flat-out called me an asshole. She jumped me. She was muttering it the whole time: What an asshole. What an asshole."Also, Franco reads Twilight and gets a straight razor shave, apparently as part of the interview.

More: Nate Silver comments on the kerfluffle
I suspect that for most liberals, any real sense of progress has now been lost. Yes, the left got a good-but-not-great health care bill, a good-but-not-great stimulus package, a good-but-not-great financial reform plan: these are a formidable bounty, and Obama and the Democratic Congress worked hard for them. But they now read as a basically par-for-the-course result from a time when all the stars were aligned for the Democrats -- rather than anything predictive of a new direction, or of a more progressive future. In contrast, as should become emphatically clear on November 2nd, the reversion to the mean has been incredibly swift.Even more: Obama and the Agent problem
What liberals haven't had, in other words, is very many opportunities to feel good about themselves, or to feel good about the future. While the White House has achieved several wins, they have never been elegant or emphatic, instead coming amidst the small-ball banality of cloture vote after cloture vote, of compromise after compromise.
Meanwhile, the White House has had two incredibly cynical moments in the past several weeks -- Gibbs' rant today and the premature firing of Shirly Sherrod three weeks ago. Both reflected politics at its worst, the clumsiest possible efforts at "triangulation".
Even yet still more: Yelling at liberals is one of the White House's few joys.

They said the "marijuana situation" down here was a bummer, that pot up in Canada was "basically free" and that it was "even cheaper than that in Quebec". I apologized and told them "like so many other things, Canada is ahead of us in this area" and that I'd "see what we could do" about the problem. :-) Watched Green Day from the second row of people. They really understand how to entertain a crowd, and played a great show. Brought up a bunch of people who looked like they were having the time of their lives.

Prop 9 Ruled Unconstitutional
Plaintiffs have demonstrated by overwhelming evidence that Proposition 8 violates their due process and equal protection rights and that they will continue to suffer these constitutional violations until state officials cease enforcement of Proposition 8. California is able to issue marriage licenses to same-sex couples, as it has already issued 18,000 marriage licenses to same sex couples and has not suffered any demonstrated harm as a result, see FF 64-66; moreover, California officials have chosen not to defend Proposition 8 in these proceedings. Because Proposition 8 is unconstitutional under both the Due Process and Equal Protection Clauses, the court orders entry of judgment permanently enjoining its enforcement; prohibiting the official defendants from applying or enforcing Proposition 8 and directing the official defendants that all persons under their control or supervision shall not apply or enforce Proposition 8.

Green Lantern
"In brightest day...
In blackest night...
No evil shall escape my sight.
Let those who worship evil's might
Beware my power... Green Lantern's light."
With those simple lines, Ryan Reynolds charmed 6500 people in Hall H and made a lifelong fan of one little boy. Contrary to many reports, the boy didn't actually ask Reynolds to recite the famous Green Lantern Oath when he got his turn at the mic during the audience Q&A at the Warner Bros. panel. He actually asked the question, "What does it feel like when you do the Green Lantern Oath?" Which is infinitely more interesting and charming than "Will you do the Green Lantern Oath?"
And what made Reynolds so likable in the moment was the genuine way he responded to the question. If you see the footage, you see him react first, an emotional beat, and then a decision. And just watching him make a decision, watching him slip into the Hal Jordan he's playing right now, and then say the Oath... not for us as an audience, because that's not the moment. He said it to that little boy. And just to him. And the look on that kid's face when the Comic-Con cameras cut to him after Reynolds finished...
Life. Changed.

"Jesus, this is your line"
"The former pastor asked me to pay him a visit when I became director for the first time," says Stückl. "I had cast a friend as Judas."
The friend was a Protestant.
The priest played various records, with music by Mendelssohn, Bach and Mozart. Which music did Christian like the most, he asked?
Bach, Stückl replied without hesitation. And that's exactly where the problem begins, the pastor replied. Bach, a Protestant, refused salvation. The music of Mendelssohn, a Jew, could offer no salvation. A true Catholic, the pastor said, could only love Mozart. Now that, he said, was the music of salvation.

Gormenghast Redux
Not many venture into the vast, shadowy front rooms, which are kept as a shrine to previous generations — a practice that irritates some members of the younger generation — and the French wallpaper is pocked with moisture stains and peeling off in sheets. In the shuttered, paneled Gothic library, Teddy Roosevelt’s photograph sits on a shelf thick with dust (Roosevelt was a pal of great-uncle Wintie Chanler); in a parlor, a bust of Julia Ward Howe, the abolitionist, author of “The Battle Hymn of the Republic” and a great-aunt, is propped on a chipped radiator. A marble plaque in the front hall is “in memoriam” to Stanford White, a family friend, who orchestrated a series of additions to the house in 1894.
Real life occurs in the rabbit warren of kitchens, pantries and servants’ bedrooms, and the small village of outbuildings — barns, cottages and carriage houses — through which family members, friends and tenants career like characters in a French farce.
What a fascinating way to live, in a crumbling house on a vast estate with a rotating cast of relatives from a really, really extened family. It makes me want to write a novel about it, but didn't John Irving already do that?

What was Darwin Thinking?
At some point it must be recognized that evolution by natural selection was not the result of years of observation in which Darwin had no working hypothesis, but instead years of observations geared towards designing proofs for a hypothesis based on little more than a hunch; a frantic search on ‘the species question’ that ensued as little more than a rat race with Alfred Russell Wallace."
I'm never convinced by these arguments that a particular person only used one mode of thought to get where they needed to go, but the conclusion ultimately reached here is precisely in agreement with that concept--that the search is one guided by both theory and observation.

Liberal Discontent
The problem for Obama, he wasn’t as lucky as Roosevelt, because when Obama took over we were still in the middle of a free fall. So his Treasury people came in and his other economic people came in and said "Hey, we need a package of $1.4 trillion." We started sending suggestions down to OMB waiting for a call back. After two and a half weeks, we started getting feedback. We put together a package that by then the target had been trimmed to $1.2 trillion. And then [White House Chief of Staff] Rahm Emanuel said to me, "Geez, do you really think we can afford to come in with a package that big, isn’t it going to scare people?" I said, "Rahm, you will need that shock value so that people understand just how serious this problem is." They wanted to hold it to less than $1 trillion. Then [Pennsylvania Senator Arlen] Specter and the two crown princesses from Maine [Sens. Olympia Snowe and Susan Collins] took it down to less than $800 billion. Spread over two and a half years, that’s a hell of a lot of money, but spread over two and a half years in an economy this large, it doesn’t have a lot of fiscal power.
Gosh, what a mess we're in.

On optimism:
"The final thing I'd say about optimism is this. If we took the loopiest, most moonbeam-addled Californian utopian internet bullshit, and held it up against the most cynical, realpolitik-inflected scepticism, the Californian bullshit would still be a better predictor of the future. Which is to say that, if in 1994 you'd wanted to understand what our lives would be like right now, you'd still be better off reading a single copy of Wired magazine published in that year than all of the sceptical literature published ever since."
On publishing:
"I think someone will make the imprint that bypasses the traditional distribution networks. Right now the big bottleneck is the head buyer at Barnes & Noble. That’s the seawall holding back the flood in publishing. Someone’s going to say, “I can do a business book or a vampire book or a romance novel, whatever, that might sell 60% of the units it would sell if I had full distribution and a multimillion dollar marketing campaign—but I can do it for 1% percent of the cost.” It has already happened a couple of times with specialty books. The moment of tip happens when enough things get joined up to create their own feedback loop, and the feedback loop in publishing changes when someone at Barnes & Noble says: “We can’t afford not to stock this particular book or series from an independent publisher.” It could be on Lulu, or iUniverse, whatever. And, I feel pretty confident saying it’s going to happen in the next five years."

Fragrance Review: Comme des Garcons Wonderwood
Luckyscent identifies the following notes: Madagascan pepper, bergamot, Somalian incense, nutmeg, Cristalon, Cashmeran, guaiac wood, cedarwood, caraway seeds, Javanol, sandalwood, vetiver, oud
It's one of the few perfumes I've tried that actually gets louder over time. It begins very light, with a very subtle cedar and then moves into the heart notes dominated by the sandalwood and Cashmeran, coupled with a note like a wooden version of a lemon that is neither citrusy, nor herbal (as lemongrass), nor synthetic (as found in polishes). Late progression turns a little bit nasty (in a cool way) as the oud and patchouli come to the fore.
I tend to like perfumes that have a little more flourish, but this one is undeniably well made. Really strong structure and a smooth progression throughout the entire experience. High marks all around.

"Ultra Batteries" comprised of XeF2, that
In its ultra-dense state, the mechanical energy transmitted to the metallized XeF2 is now stored in the substance itself as a kind of chemical energy. All it takes to release it is a perturbation of a single atom in the crystal, which will cause the entire metallized substance to spontaneously "unzip," says Yoo.
The reaction would be, quite literally, explosive. In an instant the XeF2 would turn its stored energy into thermal energy with almost 100% efficiency. The XeF2 stores about 1 kilajoule of energy per gram, or "about 10% of the energy stored in a rocket fuel of liquid H2 and O2 mixtures, or about 20% of [the energy stored in] one of the most powerful explosives, HMX," says Yoo. When viewed as a potential energy storage medium, this discovery qualifies as "a new class of energetic molecules or solid fuels," he adds.

- Shove through a jobs bill for teachers, police, firemen and other state workers.
- Keep dumping R&D money into renewable energy
These are the three highest return programs in ARRA, and the economic arguments for doing so are very basic and very clear. In concert with the further fiscal programs, the Fed needs to further expand its monetary policy by any means possible. The pain and austerity crowd must not carry the argument and the day, or we are all in for a world of trouble.

Exhausting Art
I quote this because he points to the very same mechanism — demand for novelty plus restrictions of a style leading to certain kinds of elaboration and content — decades before Martindale (Hodgson died, with this part of his book complete, in 1968), and with no pretense that he was making an original argument, as opposed to rehearsing a familiar one.
But there are obvious problems with turning this mechanism into the Universal Scientific Law of Artistic Change, as Martindale wants to do. Or rather problems which should be obvious, many of which were well put by Joseph (Abu Thomas) Levenson in Confucian China and Its Modern Fate:Historians of the arts have sometimes led their subjects out of the world of men into a world of their own, where the principles of change seem interior to the art rather than governed by decisions of the artist. Thus, we have been assured that seventeenth-century Dutch landscape bears no resemblance to Breughel because by the seventeenth century Breughel's tradition of mannerist landscape had been exhausted. Or we are treated to tautologies, according to wich art is "doomed to become moribund" when it "reaches the limit of its idiom", and in "yielding its final flowers" shows that "nothing more can be done with it" — hece the passing of the grand manner of the eighteenth entury in Europe and the romantic movement of the nineteenth.
How do aesthetic valuies really come to be superseded? This sort of thing, purporting to be a revelation of cause, an answer to a question, leaves the question still to be asked. For Chinese painting, well before the middle of the Ch'ing period, with its enshrinement of eclectic virtuosi and connoisseurs, had, by any "internal" criteria, reached the limit of its idiom and yielded its final flowers. And yet the values of the past persisted for generations, and the fear of imitation, the feeling that creativity demanded freshness in the artist's purposes, remained unfamiliar to Chinese minds. Wang Hui was happy to write on a landscape he painted in 1692 that it was a copy of a copy of a Sung original; while his colleague, Yün Shou-p'ing, the flower-painter, was described approvingly by a Chi'ing compiler as having gone back to the "boneless" painting of Hsü Ch'ung-ssu, of the eleventh century, and made his work one with it. (Yün had often, in fact, inscribed "Hsü Ch'ung-ssu boneless flower picture" on his own productions.) And Tsou I-kuei, another flower-painter, committed to finding a traditional sanction for his art, began a treatise with the following apologia:
When the ancients discussed painting they treated landscape in detail but slighted flowering plants. This does not imply a comparison of their merits. Flower painting flourished in the northern Sung, but Hsü [Hsi] and Huang [Ch'üan] could not express themselves theoretically, and therefore their methods were not transmitted.
The lesson taught by this Chinese experience is that an art-form is "exhausted"when its practitioners think it is. And a circular explanation will not hold — they think so not when some hypothetically objective exhaustion occurs in the art itself, but when outer circumstances, beyond the realm of purely aesthetic content, has changed their subjective criteria; otherwise, how account for the varying lengths of time it takes for different publics to leave behind their worked-out forms? [pp. 40–41]
Martindale seems to be completely innocent of such considerations. What he brings to this long-running discussion is, supposedly, quantitative evidence, and skill in its analysis. But this is precisely what he lacks. I have only gone over one of his analyses here, but I claim that the level of incompetence displayed here is actually entirely typical of the rest of the book.

Why Austerity Will Strangle Growth
Given this worrisome short-run outlook for GDP growth, and hence for employment, why do some people think cutting stimulus, which is what cuts to the deficit do, is the way to enhance the recovery?
Output can be written as Y = C + I + G + NX (output = consumption + investment + government spending + net exports). If we cut the deficit through reductions in spending and increases in taxes, we know G will go down (as spending falls) and that C and I will also fall (from tax increases on consumers and businesses). But somehow, the story goes, as GDP and employment are falling, confidence will go up so much that C, I, and perhaps NX will go up more than enough to compensate for the fall, and then some. However, if the confidence effect doesn't appear and generate very strong effects, and it's unlikely that it will despite the wishful thinking from some, deficit reduction makes things worse in the short-run, not better.

The Two Children Problem Reconsidered
In the mean time, here's another troublesome problem, the Two Children Problem, posed by Gary Foshee
Gary Foshee, a collector and designer of puzzles from Issaquah near Seattle walked to the lectern to present his talk. It consisted of the following three sentences: "I have two children. One is a boy born on a Tuesday. What is the probability I have two boys?"Now, the answer we arrive at might be any of the following: 1/2, 1/3, or 13/27, depending on the method used to arrive at the answer. But what actually determines the correct answer is why you told us about the boy being born on Tuesday.
So why does intuition seem to lead us so astray? Both the intuitive and the mathematically informed guesses are wrong. Are human brains just badly wired for computing probabilities?
Not so fast, says probabilist Yuval Peres of Microsoft Research. That naïve answer of 1/2? In real life, he says, that will usually be the most reasonable one.
Everything depends, he points out, on why I decided to tell you about the Tuesday-birthday-boy. If I specifically selected him because he was a boy born on Tuesday (and if I would have kept quiet had neither of my children qualified), then the 13/27 probability is correct. But if I randomly chose one of my two children to describe and then reported the child’s sex and birthday, and he just happened to be a boy born on Tuesday, then intuition prevails: The probability that the other child will be a boy will indeed be 1/2. The child’s sex and birthday are just information offered after the selection is made, which doesn’t affect the probability in the slightest.
...Peres says that we shouldn’t despair about our probabilistic intuition, as long as we apply it to familiar situations. The difficulty of these problems is rooted in their artificiality: In real life, we almost always know why the information was selected, whereas these problems have been devised to eliminate that knowledge. “The intuition develops,” he points out, “to handle situations that actually occur.”
Thomas Edison's To-Do List
Below, you can see one of Mr. Edison's to-do lists for January 3rd, 1888. List items include "Deaf Apparatus", "Electrical Piano" and "Ink for Blind". The list goes on for a number of pages—I was
initially concerned that this was the list for the day, but another subsequent list appears in the same book for April of that year, so I assume he got through the several hundred inventions in about three months, a comparatively leisurely pace. This particular page is also notable for the legible handwriting, which declines as we move through the notebook; it's a relief that old Thomas Alva may have been a workaholic genius, but also had poor penmanship.

What is the point. That is what must be borne in mind. Sometimes the point is really who wants what. Sometimes the point is what is right or kind. Sometimes the point is a momentum, a fact, a quality, a voice, an intimation, a thing said or unsaid. Sometimes it’s who’s at fault, or what will happen if you do not move at once. The point changes and goes out. You cannot be forever watching for the point, or you lose the simplest thing: being a major character in your own life.

Anosognostic, Part 2
Niederhoffer's e-mails suggested a man already obsessed with wrongness. In them, he referenced the statistical concept of path dependence; shared a series of proverbs about the game of checkers (of 5,000 such proverbs, he hazarded, about 250 concerned error); meditated on the difference between Type One mistakes (excessive credulity) and Type Two mistakes (excessive skepticism) (he himself is much more prone to Type One, he says: "I'm tremendously gullible"); observed that "one should be careful of multitasking or multiromancing"; sent me the citations for hoodoo in the Oxford English Dictionary (a hoodoo is something or someone that brings bad luck); and noted that the harpooner in Moby Dick would have made a great interview subject for this series. Finally, he pointed out that the word error has no antonym. "In retrospect," he wrote, "I know much too much about errors and much too little about the opposite, whatever it is."The best bits of the interview include the insight that he played squash too perfectly (and safely), while playing the market without enough safety, advice on avoiding "hoodoos" (people who will bring you bad luck sooner or later), and "taking out the canes":
When the public is most frightened, only the strong are left, and that's when the market is in the best possible hands. I call it taking out the canes. Whenever disaster strikes, the very sagacious wealthy people take their canes, and they hobble down from their stately mansions on Fifth Avenue, and they buy stocks to the extent of their bank balances, and then a week or two later, the market rises, they deposit the overplus in their accounts, invest it in blue-chip real estate, and retire back to their stately mansions. That's probably the best way of making money, to be a specialist in panics. Whenever there's panic hanging in the air, that's a great time to invest.

Wheeler had walked into two Pittsburgh banks and attempted to rob them in broad daylight. What made the case peculiar is that he made no visible attempt at disguise. The surveillance tapes were key to his arrest. There he is with a gun, standing in front of a teller demanding money. Yet, when arrested, Wheeler was completely disbelieving. “But I wore the juice,” he said. Apparently, he was under the deeply misguided impression that rubbing one’s face with lemon juice rendered it invisible to video cameras.It's a phenomenon that affects both the fool and the genius. We don't notice when we're screwing up. The best answer I've heard for why this is the case is that if we were realistic about our knowledge and capabilities, we'd never do anything.
The Endless Game
John Isner of Tampa, Fla., and Nicolas Mahut of France were tied at 59-59 in the fifth set at Wimbledon after exactly 10 hours of action when play was suspended because of darkness Wednesday night. It is by far the longest match in terms of games or time in the century-plus history of tennis...The 23rd-seeded Isner and the 148th-ranked Mahut, who needed to qualify to get into the tournament, shared a court for 7 hours, 6 minutes in Wednesday’s fifth set alone, enough to break the full-match record of 6:33, set at the 2004 French Open. Never before in the history of Wimbledon, which first was contested in 1877, had any match — singles or doubles, men or women — lasted more than 112 games, a mark set in 1969. Isner and Mahut played more games than that in just the fifth set, and still did not determine a victor, although the American came close: He had four match points — four chances to end things by winning the next point — but Mahut saved each one.

Update: Isner wins 70-68 in the 5th, two days after the match began.

The Quotable DeLong on Appropriate Macro Policy
Similarly, the only thing you needed to know to understand the macroeconomic policy line of the Obama administration--or, rather, what the macroeconomic policy line should be--is "short-run deficit spending to speed short-term recovery, long-run budget balance to enable long-term growth."
That is the right economic policy for the country.
