Take Distorted and Psychedelic iPhone Photos:

The iPhone has no physical shutter and instead uses photon gating on its CMOS sensor. Some parts of the image are recorded before others, much like with a scanner. The iPhone’s CMOS scanner seems to be a lot slower than, say, the CMOS sensor on your Canon point and shoot camera. Therefore, as the camera is recording the image, any changes over that small but significant amount of time are recorded. Examples of this effect from photography days of yore (caused by old focal-plane shutters that were very slow) are the famous Lartigue photo of the leaning race car. It’s also known in a related form as slit-scan photography.

What this means in iPhone terms is that if the subject or camera is moving — and if the ambient light is bright enough to allow for a fast shutter speed — the subject doesn’t blur, but rather distorts. Usually the result is pretty unpredictable, but with some practice one can see how certain effects can be created.

A New View On TV

Thursday, September 11th, 2008

Economic researchers present A New View On TV:

The variation Mr. Gentzkow and Mr. Shapiro exploited was the timing of the introduction of TV into different cities. Television began taking off in the U.S. in 1946, after a wartime ban on TV production was lifted. But the Federal Communications Commission stopped granting new commercial television licenses from September 1948 to April 1952 while it made changes in allocating broadcast spectrum. There was a long lag between when some cities got television and when others did.

The economists then looked at results of a survey of 800 U.S. schools that administered tests to 346,662 sixth-grade, ninth-grade and 12th-grade students in 1965. Their finding: Adjusting for differences in household income, parents’ educational background and other factors, children who lived in cities that gave them more exposure to television in early childhood performed better on the tests than those with less exposure.

Naturally, TV helps children from non-English-speaking families the most.

Roald Dahl’s wartime sex raids

Monday, September 8th, 2008

Drawing on previously unpublished letters, Jennet Conant has written a comprehensive account of children’s author Roald Dahl’s raucous wartime exploits:

His conquests included Millicent Rogers, the glamorous heiress to a Standard Oil fortune; and Clare Boothe Luce, a right-wing congresswoman and the sexually frisky wife of the publisher of Time magazine.

Dahl would later complain to friends that Boothe Luce, 13 years his senior, had left him “all f***** out” after three nights of bedroom capers.

“Dahl’s superiors watched his rake’s progress with grudging admiration,” Conant writes in The Irregulars, to be published in Britain on September 9. “A certain amount of hanky-panky was condoned, especially when it was for a good cause.”

Injured during training as an RAF pilot, Dahl fought in the Middle East before he was declared unfit to fly and was shipped to the Washington embassy in 1942. He immediately cut a swathe as a 6ft 6in battle-scarred pilot who was nonetheless horrified to find himself “in the middle of a cocktail mob in America”.

Making Canned Halloween Monstrosities

Sunday, September 7th, 2008

Making Canned Halloween Monstrosities looks like good, clean fun. The label reads:

Unknown Specimen
Recovered from chest cavity of decayed animated corpse. Animation of corpse ceased upon removal. Specimen began to dissolve within moments of removal from host. Dissolution ceased with formaldehyde and acetone.
Haiti, 1894

The specimen is in fact an expands-in-water snake in a bottle from the dollar store:

  • The snake was cut up a little before being put into the jar to make it look somewhat decayed when it expanded.
  • A few grains of instant coffee were added to the water to give it a murky brown look.
  • A small spoonful of used coffee grounds was added to the water to enhance the “decayed” sort of look.

60 Minutes on Dungeons & Dragons

Thursday, August 28th, 2008

Oddly enough, I never saw the original 60 Minutes piece on Dungeons & Dragons — and the game’s tenuous link to teen suicide — back when it aired back in 1985:

That second video goes into a piece on Thomas Radecki:

Founder of NCTV (National Coalition for Television Violence) and board member on Tipper Gore‘s PMRC group who once used quoted material from Rona Jaffe’s novel Mazes & Monsters as if it was real and factual. Radecki, a psychologist, lost his license to practice for five years for engaging in immoral conduct with a patient. He has since returned to his practice.

Is H.L. Mencken Alive and Well at the NYT?

Thursday, August 28th, 2008

David Friedman cites the New York Times on corporate taxes:

Two out of every three United States corporations paid no federal income taxes from 1998 through 2005, according to a report released Tuesday by the Government Accountability Office, the investigative arm of Congress.

Perhaps you’ve heard that stat bandied about recently. Friedman also cites the Reuters story on the same report:

The Government Accountability Office said 72 percent of all foreign corporations and about 57 percent of U.S. companies doing business in the United States paid no federal income taxes for at least one year between 1998 and 2005.

Hmm…

The GAO study itself says this:

As figure 2 shows, about 72 percent of FCDCs and 55 percent of USCCs reported no tax liability for at least 1 year during the 8 years. About 57 percent of FCDCs and 42 percent of USCCs reported no tax liability in multiple years — 2 or more years — and about 34 percent of FCDCs and 24 percent of USCCs reported no tax liability for at least half the study period — 4 or more years.

This leads Friedman to ask, Is H.L. Mencken Alive and Well at the NYT?

Mencken’s famous bathtub hoax was an invented history of the bathtub, designed to appeal to what readers wanted to believe about the ignorance and irrationality of people in the past. He published it as a demonstration of human credulity, reported with glee on how many people repeated it as gospel despite its obvious inconsistency with easily established historical facts, published multiple retractions pointing out how obviously false it was — and, by his account, never managed to kill the story.

My previous post pointed to a modern equivalent. The NYT (and, I think, the AP, but not Reuters, which got it right) misread a GAO report in a way that drastically altered its meaning, converting it from a plausible but boring result (a substantial majority of corporations reported no taxable income in at least one year out of an eight year period) to a wildly implausible result that nicely fitted what a lot of people wanted to believe (two-thirds of corporations reported no taxable income over that eight year period). They simultaneously made another mistake almost as bad, calculating what the corporations “should” have owed on the basis of their revenue, not their profit. The Times discovered the latter mistake and corrected it; so far as I can tell, they have not yet noticed the former mistake.

Googling around, I found an enormous numbers of online references to the story. So far, I have not found a single one, other than my piece on this blog, that spotted the mistake. I’ve posted the actual facts on a fair number of them, but it’s like a teacup in a tempest. I have no doubt that, years from now, millions of people will still remember the scandalous, and wholly imaginary, fact from the Times article.

For your enjoyment, I append “A Neglected Anniversary” by H. L. Mencken, first published in the New York Evening Mail, December 28, 1917.

On December 20 there flitted past us, absolutely without public notice, one of the most important profane anniversaries in American history, to wit, the seventy-fifth anniversary of the introduction of the bathtub into These States. Not a plumber fired a salute or hung out a flag. Not a governor proclaimed a day of prayer. Not a newspaper called attention to the day.

True enough, it was not entirely forgotten. Eight or nine months ago one of the younger surgeons connected with the Public Health Service in Washington happened upon the facts while looking into the early history of public hygiene, and at his suggestion a committee was formed to celebrate the anniversary with a banquet. But before the plan was perfected Washington went dry,* and so the banquet had to be abandoned. As it was, the day passed wholly unmarked, even in the capital of the nation. (*This was war-time Prohibition, preliminary to the main catastrophe. — HLM)

Bathtubs are so common today that it is almost impossible to imagine a world without them. They are familiar to nearly everyone in all incorporated towns; in most of the large cities it is unlawful to build a dwelling house without putting them in; even on the farm they have begun to come into use. And yet the first American bathtub was installed and dedicated so recently as December 20, 1842, and, for all I know to the contrary, it may still be in existence and in use.

Curiously enough, the scene of its setting up was Cincinnati, then a squalid frontier town, and even today surely no leader in culture. But Cincinnati, in those days as in these, contained many enterprising merchants, and one of them was a man named Adam Thompson, a dealer in cotton and grain. Thompson shipped his grain by steamboat down the Ohio and Mississippi to New Orleans, and from there sent it to England in sailing vessels. This trade frequently took him to England, and in that country, during the ’30s, he acquired the habit of bathing.

The bathtub was then still a novelty in England. It had been introduced in 1828 by Lord John Russell and its use was yet confined to a small class of enthusiasts. Moreover, the English bathtub, then as now, was a puny and inconvenient contrivance — little more, in fact, than a glorified dishpan — and filling and emptying it required the attendance of a servant. Taking a bath, indeed, was a rather heavy ceremony, and Lord John in 1835 was said to be the only man in England who had yet come to doing it every day.

Thompson, who was of inventive fancy — he later devised the machine that is still used for bagging hams and bacon — conceived the notion that the English bathtub would be much improved if it were made large enough to admit the whole body of an adult man, and if its supply of water, instead of being hauled to the scene by a maid, were admitted by pipes from a central reservoir and run off by the same means. Accordingly, early in 1842 he set about building the first modern bathroom in his Cincinnati home — a large house with Doric pillars, standing near what is now the corner of Monastery and Orleans streets.

There was then, of course, no city water supply, at least in that part of the city, but Thompson had a large well in his garden, and he installed a pump to lift its water to the house. This pump, which was operated by six Negroes, much like an old-time fire engine, was connected by a pipe with a cypress tank in the garret of the house, and here the water was stored until needed. From the tank two other pipes ran to the bathroom. One, carrying cold water, was a direct line. The other, designed to provide warm water, ran down the great chimney of the kitchen, and was coiled inside it like a giant spring.

The tub itself was of new design, and became the grandfather of all the bathtubs of today. Thompson had it made by James Cullness, the leading Cincinnati cabinetmaker of those days, and its material was Nicaragua mahogany. It was nearly seven feet long and fully four feet wide. To make it water-tight, the interior was lined with sheet lead, carefully soldered at the joints. The whole contraption weighed about 1,750 pounds, and the floor of the room in which it was placed had to be reinforced to support it. The exterior was elaborately polished.

In this luxurious tub Thompson took two baths on December 20, 1842 — a cold one at 8 a.m. and a warm one some time during the afternoon. The warm water, heated by the kitchen fire, reached a temperature of 105 degrees. On Christmas day, having a party of gentlemen to dinner, he exhibited the new marvel to them and gave an exhibition of its use, and four of them, including a French visitor, Col. Duchanel, risked plunges into it. The next day all Cincinnati — then a town of about 100,000 people — had heard of it, and the local newspapers described it at length and opened their columns to violent discussions of it.

The thing, in fact, became a public matter, and before long there was bitter and double- headed opposition to the new invention, which had been promptly imitated by several other wealthy Cincinnatians. On the one hand it was denounced as an epicurean and obnoxious toy from England, designed to corrupt the democratic simplicity of the Republic, and on the other hand it was attacked by the medical faculty as dangerous to health and a certain inviter of “phthisic, rheumatic fevers, inflammation of the lungs and the whole category of zymotic diseases.” (I quote from the Western Medical Repository of April 23, 1843.)

The noise of the controversy soon reached other cities, and in more than one place medical opposition reached such strength that it was reflected in legislation. Late in 1843, for example, the Philadelphia Common Council considered an ordinance prohibiting bathing between November 1 and March 15, and it failed of passage by but two votes. During the same year the legislature of Virginia laid a tax of $30 a year on all bathtubs that might be set up, and in Hartford, Providence, Charleston and Wilmington (Del.) special and very heavy water rates were levied upon those who had them. Boston, very early in 1845, made bathing unlawful except upon medical advice, but the ordinance was never enforced and in 1862 it was repealed.

This legislation, I suspect, had some class feeling in it, for the Thompson bathtub was plainly too expensive to be owned by any save the wealthy; indeed, the common price for installing one in New York in 1845 was $500. Thus the low caste politicians of the time made capital by fulminating against it, and there is even some suspicion of political bias in many of the early medical denunciations. But the invention of the common pine bathtub, lined with zinc, in 1847, cut off this line of attack, and thereafter the bathtub made steady progress.

The zinc tub was devised by John F. Simpson, a Brooklyn plumber, and his efforts to protect it by a patent occupied the courts until 1855. But the decisions were steadily against him, and after 1848 all the plumbers of New York were equipped for putting in bathtubs. According to a writer in the Christian Register for July 17, 1857, the first one in New York was opened for traffic on September 12, 1847, and by the beginning of 1850 there were already nearly 1,000 in use in the big town.

After this medical opposition began to collapse, and among other eminent physicians Dr. Oliver Wendell Holmes declared for the bathtub, and vigorously opposed the lingering movement against it in Boston. The American Medical Association held its annual meeting in Boston in 1849, and a poll of the members in attendance showed that nearly 55 per cent of them now regarded bathing as harmless, and that more than 20 per cent advocated it as beneficial. At its meeting in 1850 a resolution was formally passed giving the imprimatur of the faculty to the bathtub. The homeopaths followed with a like resolution in 1853.

But it was the example of President Millard Fillmore that, even more than the grudging medical approval, gave the bathtub recognition and respectability in the United States. While he was still Vice-President, in March, 1850, he visited Cincinnati on a stumping tour, and inspected the original Thompson tub. Thompson himself was now dead, but his bathroom was preserved by the gentlemen who had bought his house from the estate. Fillmore was entertained in this house and, according to Chamberlain, his biographer, took a bath in the tub. Experiencing no ill effects, he became an ardent advocate of the new invention, and on succeeding to the Presidency at Taylor’s death, July 9, 1850, he instructed his secretary of war, Gen. Charles M. Conrad, to invite tenders for the construction of a bathtub in the White House.

This action, for a moment, revived the old controversy, and its opponents made much of the fact that there was no bathtub at Mount Vernon, or at Monticello, and that all the Presidents and other magnificoes of the past had got along without any such monarchical luxuries. The elder Bennett, in the New York Herald, charged that Fillmore really aspired to buy and install in the White House a porphyry and alabaster bath that had been used by Louis Philippe at Versailles. But Conrad, disregarding all this clamor, duly called for bids, and the contract was presently awarded to Harper & Gillespie, a firm of Philadelphia engineers, who proposed to furnish a tub of thin cast iron, capable of floating the largest man.

This was installed early in 1851, and remained in service in the White House until the first Cleveland administration, when the present enameled tub was substituted. The example of the President soon broke down all that remained of the old opposition, and by 1860, according to the newspaper advertisements of the time, every hotel in New York had a bathtub, and some had two and even three. In 1862 bathing was introduced into the Army by Gen. McClellan, and in 1870 the first prison bathtub was set up at Moyamensing Prison, in Philadelphia.

So much for the history of the bathtub in America. One is astonished, on looking into it, to find that so little of it has been recorded. The literature, in fact, is almost nil. But perhaps this brief sketch will encourage other inquirers and so lay the foundation for an adequate celebration of the centennial in 1942.

Mencken’s introduction (from A Mencken Chrestomathy, published by Alfred A. Knopf, 1949):

The success of this idle hoax, done in time of war, when more serious writing was impossible, vastly astonished me. It was taken gravely by a great many other newspapers, and presently made its way into medical literature and into standard reference books. It had, of course, no truth in it whatsoever, and I more than once confessed publicly that it was only a jocosity… Scarcely a month goes by that I do not find the substance of it reprinted, not as foolishness but as fact, and not only in newspapers but in official documents and other works of the highest pretensions.

Analog Meets Its Match in Red Digital Cinema’s Ultrahigh-Res Camera

Tuesday, August 26th, 2008

Michael Behar of Wired says that Analog Meets Its Match in Red Digital Cinema’s Ultrahigh-Res Camera — but I find the company’s founder just as fascinating:

Jim Jannard, 59, is the billionaire founder of Red. In 1975 he spent $300 to make a batch of custom motocross handlebar grips, which he sold from the back of a van. He named his company Oakley, after his English setter, and eventually expanded into sci-fi-style sunglasses, bags, and shoes. In November of last year he sold the business to Luxottica, the owner of Ray-Ban, for a reported $2.1 billion.

OK, you’re wondering, so what’s so cool about this camera?

His team of engineers and scientists have created the first digital movie camera that matches the detail and richness of analog film. The Red One records motion in a whopping 4,096 lines of horizontal resolution — “4K” in filmmaker lingo — and 2,304 of vertical. For comparison, hi-def digital movies like Sin City and the Star Wars prequels top out at 1,920 by 1,080, just like your HDTV. (There’s also a slightly higher-resolution option called 2K that reaches 2,048 lines by 1,080.) Film doesn’t have pixels, but the industry-standard 35-millimeter stock has a visual resolution roughly equivalent to 4K. And that’s what makes the Red so exciting: It delivers all the dazzle of analog, but it’s easier to use and cheaper — by orders of magnitude — than a film camera. In other words, Jannard’s creation threatens to make 35-mm movie film obsolete.
[...]
Soderbergh took two prototypes into the Spanish wilderness. “It felt like someone crawled inside my head when they designed the Red,” he says. What impressed him most was the cameras’ sturdiness. Movie sets are often a flurry of crashes and explosions, which can vibrate sensitive electronics, introducing visual noise known as microphonics into images. “A lot of cameras with electronics in them, if you fired a 50-caliber automatic weapon a few inches away — which we did — you’d get microphonics all over the place,” Soderbergh says. “We beat the shit out of the Reds on the Che films, and they never skipped a beat.”

Then there’s the economics: The Red One sells for $17,500 — almost 90 percent less than its nearest HD competitor. The savings are even greater relative to a conventional film camera. Not that anyone buys those; filmmakers rent them, usually from Panavision, an industry stalwart in Woodland Hills, California. Panavision doesn’t publicize its rates, but a Panavision New Zealand rental catalog quotes $25,296 for a four-week shoot — more than the cost of purchasing a Red. “It’s clearly the future of cinematography,” Peter Hyams says. “You can buy this camera. You can own it. That’s why people are excited.”
