arXiv paper

Automatic Meaning Discovery Using Google


We have found a method to automatically extract the meaning of words and phrases from the world-wide-web using Google page counts. The approach is novel in its unrestricted problem domain, simplicity of implementation, and manifestly ontological underpinnings. The world-wide-web is the largest database on earth, and the latent semantic context information entered by millions of independent users averages out to provide automatic meaning of useful quality. We demonstrate positive correlations, evidencing an underlying semantic structure, in both numerical symbol notations and number-name words in a variety of natural languages and contexts. Next, we demonstrate the ability to distinguish between colors and numbers, and to distinguish between 17th century Dutch painters; the ability to understand electrical terms, religious terms, emergency incidents, and we conduct a massive experiment in understanding WordNet categories; the ability to do a simple automatic English-Spanish translation.

Also: Wikipedia article on the "EURion constellation," or special images on US and Euro notes meant to be detectable by software inside scanners:

Users of recent versions of image editors, such as Adobe Photoshop or Paint Shop Pro, discovered that these also refuse to process banknotes. According to an article in Wired magazine, the banknote detection code in these applications, called the Counterfeit Deterrence System (CDS), was designed by the Central Bank Counterfeit Deterrence Group and supplied to companies such as Adobe as a binary module. However, experiments by Steven J. Murdoch and others showed that this banknote detection code does not rely on the EURion pattern. It detects other features of banknote designs that have yet to be described in public.

Uday Hussein and the Wood Chipper

In the latest issue of Counterpunch, Alexander Cockburn writes:

Discussing an Iraqi fakir touted by the Bush administration, I recently wrote that "In atrocity stories there are some things that don't ring true, even when dealing with such well-credentialed butchers as Saddam and his sons. Take the story, subsequently identified as one concocted by a Western intelligence agency, that Uday had put some of his victims through a wood chipper. Anyone using these chippers knows the damn things jam if inconvenienced by anything with a diameter larger than a stick of asparagus...
....Uday's chipper, whose origin can probably be traced to a scene in the movie Fargo, just didn't passed muster..."
I was being slightly frivolous about the woodchipper, but the letters poured in.
Then one of the letters:
Dear Mr Cockburn, Your fine web piece of Jan 8-9 contains a factual error that you might wish to be aware of. Although the residential, light-commercial, tree-service-type wood chipper might jam if fed a human body (they are designed to chew up brush and limbs), the type used in land clearing (the source of woodchips we use for playground surfacing) and pulp-chip operations would not stutter if fed a regiment—one at a time, of course.

And then a pointer to a company called Morbark, which offers this customer testimonial:

One long-time Morbark customer put it this way: "If you're serious about chipping wood or grinding wood, Morbark is the only way to go."

quoting shakespeare

If you cannot understand my argument, and declare "It's Greek to me", you are quoting Shakespeare; if you claim to be more sinned against than sinning, you are quoting Shakespeare; if you recall your salad days, you are quoting Shakespeare; if you act more in sorrow than in anger, if your wish is father to the thought, if your lost property has vanished into thin air, you are quoting Shakespeare; if you have ever refused to budge an inch or suffered from green-eyed jealousy, if you have played fast and loose, if you have been tongue-tied, a tower of strength, hoodwinked or in a pickle, if you have knitted your brows, made a virtue of necessity, insisted on fair play, slept not one wink, stood on ceremony, danced attendance (on your lord and master), laughed yourself into stitches, had short shrift, cold comfort or too much of a good thing, if you have seen better days or lived in a fool's paradise - why, be that as it may, the more fool you, for it is a foregone conclusion that you are (as good luck would have it) quoting Shakespeare; if you think it is early days and clear out bag and baggage, if you think it is high time and that that is the long and short of it, if you believe that the game is up and that truth will out even if it involves your own flesh and blood, if you lie low till the crack of doom because you suspect foul play, if you have your teeth set on edge (at one fell swoop) without rhyme or reason, then - to give the devil his due - if the truth were known (for surely you have a tongue in your head) you are quoting Shakespeare; even if you bid me good riddance and send me packing, if you wish I were dead as a door-nail, if you think I am an eyesore, a laughing stock, the devil incarnate, a stony-hearted villain, bloody-minded or a blinking idiot, then - by Jove! O Lord! Tut, tut! for goodness' sake! what the dickens! but me no buts - it is all one to me, for you are quoting Shakespeare.

A question posed about online course management systems

Course Management Systems: Trapped Content Silos or Sharing Platforms? (PDF)

An excerpt

However, while more and more faculty and programs have come to rely upon course management systems over the past few years, rapid technology and business changes (mergers, elimination of products, etc.) have brought about a sense of discomfort in the community.
Questions arise: 1) How invested is my institution in one platform? 2) If I put my material in a CMS, can I get it out? 3) What happens if my institution switches systems? 4) How do I share materials between systems? 5) If I have just arrived from an institution that uses a different CMS, how do I use what I have already created? 6) How can my content development work be "future proofed" against CMS changes?

The answer to these questions is as follows

1) overinvested.
2) probably not.
3) you lose everything.
4) you don't, easily.
5) you can't.
6) don't use a "course management system" for pedagogic material:


We've arrived at the answer to the question posed by this paper: Trapped Content Silos.

Strawberry Tsunami vs Strawberry Nirvana

Gloria noticed that they're not selling the "Strawberry Tsunami" flavor any more at the Jamba Juice in the Tresidder student union on the Stanford campus. It might have been replaced by something called "Strawberry Nirvana." You can still buy a Strawberry Tsunami in Hawaii. But on another web page for a Concord, CA shopping mall, it looks like "Strawberry Tsunami" and "Strawberry Nirvana" are different drinks.

The Thinking Carpet

It may be thoughtful, but still, it's a bit wordy:

On the one hand, the uniqueness of the 'Thinking Carpet' is going to lie in the invisible, simple and space-saving placement of sensors for the widest variety of functions, functions for which optically visible devices are still being utilised today. In addition, microchips that have been integrated into the flooring, networked with each other and are computer-controlled can register several, even different sensory signals at the same time, and then analyse them correspondingly.

Let the record show that carpets learned to think before they learned to fly.

String Theory better left to mathematicians?

Kenneth Lane, a theoretical high-energy physicist at BU, said [string theory] research is better left to mathematicians.
"String theory is not physics," Lane said. "It's lovely mathematics, but it makes no physics predictions. We're interested in the outcomes of experiments. If all we did was string theory, our experimentalists wouldn't know what to do. That's why it's not popular at BU."
Not surprisingly, some debate has risen among string theorists for what they view as BU's snubbing of a vital discipline.
Cumrun Vafa, a string theorist at Harvard University, said that for a particular faculty member to feel that string theory should be relegated to the mathematics department is wrong.
"To try to categorically deny the existence of a subject is just childish," Vafa said.

Chess Players give 'Check' a new meaning

Excerpt: (NYT) JAY BONIN, an international chess master who lives in New York, is one of the busiest players in the country. He takes part in face-to-face tournament matches every week and also regularly participates in games of speed chess at chessclub.com, the Internet Chess Club. He estimated that he has played more than 20,000 games online in the last three or four years.

Mr. Bonin is much more active than most elite players, but he is doing what most serious players have long thought is necessary: playing frequently to stay in peak form. Now, however, because of the widespread availability of databases of games and the growing strength of chess software, such activity may actually be making it easier to beat him.

Mr. Bonin said that he recently lost a tournament game to a weaker player who had not competed in years, but who had sprung a surprise move on him in one of Mr. Bonin's favorite openings.

''The line he played reeked of preparation,'' he said.

Chris Ashley: Look, See

An admirable effort to find art in simple blobs of HTML: link

Added later: Here's Ashley's thinking about this technique. This stuff is very nice, I like it a lot. Some excerpts:

The making of any visual arts, or any art for that matter, is always about solving problems. Whether it's how to depict an object, how to use color, how to convey meaning through an image, or even what to make art about, an artist is is alway confronting problems, asking questions about what to do, and posing possible solutions, which leads to more questions and, hopefully, more solutions....
I already knew how to make hand-coded HTML tables, but given the potential complexity of code required to make an image I knew that I could make these drawings fairly quickly in an HTML editor. For all their supposed simplicity, it's not as easy as it looks; the hardest part is, of course, the question of what what to make.
I have found that a weblog can be a very effective work space that, for my purposes, became a studio, gallery, and archive...

Steve Martin on Johnny Carson

Your Nebraskan pragmatism—and knowledge of the magician's tricks—tilted you toward the sciences, especially astronomy. (Maybe this is why the occultists, future predictors, spoon-benders or mind readers on your show never left without having been challenged.) You knew how to treat everyone, from the pompous actor to the nervous actress, and which to give the appropriate kindness. You enjoyed the unflappable grannies who knitted log-cabin quilts, as well as the Vegas pros who machine-gunned the audience into hysterical fits. You were host to writers, children, intellectuals and nitwits and served them all well, and served the audience by your curiosity and tolerance. You gave each guest the benefit of the doubt, and in this way you exemplified an American ideal: you're nuts but you're welcome here.

For many this is just the beginning. The game is ever changing and open to new rules and interpretations so the Guiding Light was developed.

Some players practice Cosmic Cube Control. Energizing your cubes contributes to the fun; some say it's a necessary ritual to ensure unfailing tesseract compliance.

Enter the SYNUS concept vehicle, a mobile techno sanctuary sculpted in urban armor and inspired by the popular B-cars of congested international hotspots. Short and slim for easy city maneuvering, it looks bank-vault tough on the outside - with intimidating and outrageous styling that even features a vault-style spinner handle in back with deadbolt door latching. When parked and placed in secure mode, SYNUS deploys protective shutters over the windshield and side glass...

Just because comment spammers post URLs doesn't mean *I* shouldn't be able to unless I'm a "friend" or have provided some other authentication information.

The solution to Comment Spam is for Six Apart or whoever else wants to provide blog comment tools to embed a graphical challenge code to be typed in by the person who is submitting the comment.

All I had was a big, green bag full of clothes that my kids wanted to donate. We'd all felt so terrible when we saw what the tsunami had done, especially after we had had such a great Christmas with lots of presents and food.

Virtual Mr Toad's Wild Ride


An article at Boing Boing says that

When Walt Disney World's Mr Toad ride shut down to make way for a Pooh ride, diehard fans were heartbroken. One fan set out to recreate the entire ride as a 3D computer-generated environment...

But I can report that Mr Toad's ride was still at Disneyland (OK, they're talking about Disneyworld, I see), as of spring 2004. But is the ride at Disneyland gone now, too?

It's the only ride at Disneyland I like. Here's an excerpt from the VR project:

And what an experience! What made the ride so unbelievably special? It's hard to describe. Each side took you completely out of reality, sending you instantly into another world. Part of the appeal was that, unlike other Disney attractions, the movie this ride was based on wasn't well known, so part of the fun was to try and figure out what the ride was all about. For many kids growing up in the 1970's and early 1980's, Mr. Toad was the first "thrill ride" they experienced. And it was the only ride at Disney with a naked lady, the only ride that sent you hurtling head-on into an oncoming train, and the only ride where you ended up in hell at the end!

Titan vs Santa Barbara

[This image was] taken from an altitude of about 8 kilometers (about 5 miles) and a resolution of about 20 meters (about 65 feet) per pixel. The images were taken by the Descent Imager/Spectral Radiometer, one of two NASA instruments on the probe.

So I spent awhile looking for a photo that captured the view of Santa Barbara I had in mind, but found only satellite images (such as the one I put below the Titan photo). In any case, it's 5 miles up = 26,000 feet, cruising altitude.

Forty Pig & Whistles

From an article in the Economist on Britain's newly liberal drink licensing laws:

Britain's cities are already among the booziest in the world, and worry is that they will become more alcohol-sodden once the old restrictions are done away with. The new act addresses some fears by giving local authorities more powers to move against troublesome pubs. But as Andrew McNeill, director of the Institute for Alcohol Studies, and independent think-tank, puts it, "It's not that the Pig & Whistle is badly managed. The problem is that there are 40 Pig & Whistles in a tiny area."

Looks like there's one on Geary in SF.

Quality of Life

A movie that's about San Francisco graffiti painters in the Mission.

Days after the screening, he is doing a "Quality of Life" walking tour in the Mission with Smith, pointing out the various film spots. He notes a second-story wall above Valencia that was used as a set for the film's most powerful scene, in which Laine pours out his anguish in the all-night-long execution of a huge and extraordinary work of art.
"That was my design," he says modestly. "It was designed loosely on Picasso's 'Burial of Casagemas' painting, but I put a crown on the body, since in graffiti parlance, a 'king' is an artist. That mural really was done all night long. And you can still see the outline on the wall; all that's left are the lines where we buffed it out."

It certainly has all the attributes I was looking for, including a good description of the probabilities of winning, pot odds, and other statistics during play. Also it has some nice robots to place against.

The Buffalo Commons


In 1987, as part of their famous, controversial proposal for a "Buffalo Commons," Drs. Frank and Deborah Popper of Rutgers University showed that hundreds of counties in the American West still have less than a sparse 6 persons per square mile -- the density standard Frederick Jackson Turner used to declare the American Frontier closed in 1893. Many have less than 2 persons per square mile!The [United States] frontier never came close to disappearing, and in fact has expanded in recent years. The 1980 Census showed 388 frontier counties west of the Mississippi. The 1990 Census shows 397 counties in frontier status, and the 2000 Census shows even more. Most of this frontier expansion is in the Great Plains. Kansas actually has more land in frontier counties than it did in 1890.

So—the idea is to put hundreds of thousands of Buffalo in there, and let them stampede. It's a great idea, and would eventually become the greatest thing to see in the entire natural world. In particular, it would make the high plains of the United States and Canada into one of the world's great tourist destinations.

The Big Empty


With an interesting B/W photo of Norman Mailer. Excerpt:

To win this war [against corporations] will take, at least, 50 years and a profound revolution in America. We'll have to get away from manipulation. What we've got now is a species of economic, political, and spiritual brainwashing, vastly superior to the old Soviets, who were endlessly crude in their attempts. Our governmental and corporate leaders are much more subtle. I remember years ago when my son was around 15, he wore a shirt that said Stussy on it. And I said, "Not only do you spend money to buy the shirt, but you also advertise the company that sold it to you." And he said, "Dad, you just don't get it." All right, he was right, I didn't get it.

But I liked this the best:

The small businessman is always taking his chances. He leads an existential life. He's gambling that his wit, his energy, and his ideas of what will work in the marketplace will be successful. He can be a sonofabitch, but at least he's out there in the middle of life. He could be creating something that's awful, but at least, he's taking chances...

Harmonious in mind and mouth

Excerpt from a police training program:

We know that 98 percent of the altercations between police and civilians begin with mind and mouth disharmony. The way we are inclined to talk naturally, therefore, must be wrong. Words that flow easily from the lips will usually be wrong because we work the underbelly of society, people at their worst. We are not hired to express our feelings; we are hired to solve problems. Verbal Judo is the opposite of natural language, it is tactical language, or language shaped to achieve a professional goal.

More at Verbal Judo

Added later:

Somehow this paragraph, and the idea of police officers deploying Verbal Judo, reminded me of Wittgenstein. So I flipped open Philosophical Investigations, I and found this:

68. If I tell someone—"Stand roughly here"—may not this explanation work perfectly? And cannot every other one fail too?
But isn't it an inexact explanation? Yes—why shouldn't we call it "inexact"? Only let us understand what "inexact" means. For it does not mean "unusable." And let us consider what we call an "exact" explanation in contrast with this one. Perhaps something like drawing a chalk line around an area? Here it strikes us at once that the line has breadth. So a colour-edge would be more exact. But has this exactness still got a function here: isn't the engine idling?

There you've got it—the sobriety test, chalk outline, and the idling engine. It's a philosophical police traffic stop.

The Chicken Little Logic Headache

From the NYT, 7 January 2005, "Heavy Rains in West Begin Chasing Its Drought," by By Dean E. Murphy:

Persistent wet weather across much of the West has done something remarkable to the scientists and water officials who fret about the region's five-year-old drought: They feel a lot less like Chicken Little.
"This is the kind of sky we like to see fall," Herbert R. Guenther, director of the Arizona Department of Water Resources, said in a telephone interview from Phoenix. "In rain - not us running around wringing our hands and screaming because of lack of water."

So—less like Chicken Little in that they were warning about important things that needed to happen, but that now that it has rained, they don't need to warn anymore? But that's not less like Chicken Little, that's not Chicken Little to any degree, since the essence of Chicken Littlehood is warning about things that aren't going to happen, and no one should care whether they happen.



[Note to self: don't think about this anymore. It's been three days already.]

The Salvador Option

Here's some more scary thinking about Iraq and what to do about the big mess there. The natural thing to do after a big failure is to "declare success," then pack up the old kit bags and smile, smile, smile. And that's obviously what has to happen in the long term—the US will have no military presence to speak of in Iraq. But I doubt too many people in Chimpdom have come around to that way of thinking. Yet. In the meantime, there's the "Salvador Option":

The U.S. government funded or supported "nationalist" forces that allegedly included so-called death squads directed to hunt down and kill rebel leaders and sympathizers. Eventually the insurgency was quelled, and many U.S. conservatives consider the policy to have been a success—despite the deaths of innocent civilians...

Flushing Garfield

From an article describing the decision of the Los Angeles Times to drop the comic "Garfield":

Gene Weingarten, a humor columnist for The Washington Post and Washington Post Writers Group, praised the Times decision during his weekly washingtonpost.com chat yesterday. He said the paper displayed "the kind of cojones missing in too many places" and described "Garfield" as "a strip produced by a committee, devoid of originality, devoid of guts, a strip cynically DESIGNED to be inoffensive and bad, on the theory that public tastes are insipid.

I've had the same feeling for years—"Garfield" is not only bad, it's almost always incredibly bad.

Now: what can be done about Ziggy?

Eric H Lenneberg

When I buy used books via Alibris or Amazon, they sometimes arrive with the previous owner's "Ex Libris" stickers attached, or some other interesting information, sometimes even papers stuck in the middle of the book.

I bought a copy of a 1968 book edited by Michael A. Arbib called "Algebraic Theory of Machines, Languages, and Semigroups" a couple of weeks ago. Inside its cover, I found a sticker for someone named Eric H Lenneberg, and also a stamp, "Department of Psychology, Uris Hall, Cornell University."

Here's what one web page has to say:

Eric H[einz] Lenneberg (1921 - 1975) was a linguist who pioneered ideas on language acquisition and cognitive psychology [and] more generally about innateness. He was born in Duesseldorf, Germany. As a jew, he left Germany because of Nazi terrorism. As a professor in psychology, he worket at the Harvard Medical School and at the University of Michigan in Ann Harbor.
His 1964 paper "The Capacity of Language Acquisition" sets forth the seminal arguments picked up later by Noam Chomsky and popularized by Steven Pinker in his book, "The Language Instinct".

Here's a link with a great photo of him, in black and white (all great photos are black and white).

People lie, numbers don't

The new CBS TV show numb3rs has the catchphrase "People lie, numbers don't."

I've known quite a few numbers who told me fibs, or at least grossly misrepresented themselves in the context of the "strong law for small numbers." The strong law is encapsulated in Richard Guy's observation that "There are not enough small numbers to satisfy all the demands placed on them."

As a result, the hard-pressed small numbers, particularly when they gather together, end up telling a lot of lies to unsuspecting mathematicians. Three is a big liar, but probably not as bad two, though, and certainly not so bad as 1, the biggest liar of them all.

Charles Dickens [1868]

From American Notes (pg 268 or so in that web version):

"You carry," says the stranger, "this jealousy and distrust into every transaction of public life. By repelling worthy men from your legislative assemblies, it has bred up a class of candidates for the suffrage, who, in their every act, disgrace your Institutions and your people's choice. It has rendered you so fickle, and so given to change, that your inconstancy has passed into a proverb; for you no sooner set up an idol firmly than you are sure to pull it down and dash it into fragments: and this because, directly you reward a benefactor, or a public servant, you distrust him, merely because he is rewarded; and immediately apply yourselves to find out, either that you have been too bountiful in your acknowledgments, or he remiss in his deserts. Any man who attains a high place among you, from the President downwards, may date his downfall from that moment; for any printed lie that any notorious villain pens, although it militate directly against the character and conduct of a life, appeals at once to your distrust, and is believed. You will strain at a gnat in the way of trustfulness and confidence, however fairly won and well deserved; but you will swallow a whole caravan of camels, if they be laden with unworthy doubts and mean suspicions. Is this well, think you, or likely to elevate the character of the governors or the governed among you?"
The answer is invariably the same: "There's freedom of opinion here, you know. Every man thinks for himself, and we are not to be easily overreached. That's how our people come to be suspicious."
Another prominent feature is the love of "smart" dealing: which gilds over many a swindle and gross breach of trust; many a defalcation, public and private; and enables many a knave to hold his head up with the best, who well deserves a halter: though it has not been without its retributive operation, for this smartness has done more in a few years to impair the public credit, and to cripple the public resources, than dull honesty, however rash, could have effected in a century. The merits of a broken speculation, or a bankruptcy, or of a successful scoundrel, are not gauged by its or his observance of the golden rule, "Do as you would be done by," but are considered with reference to their smartness. I recollect, on both occasions of our passing that ill-fated Cairo on the Mississippi, remarking on the bad effects such gross deceits must have, when they exploded, in generating a want of confidence abroad, and discouraging foreign investment: but I was given to understand that this was a very smart scheme, by which a deal of money had been made: and that its smartest feature was, that they forgot these things abroad in a very short time, and speculated again as freely as ever. The following dialogue I have held a hundred times: "Is it not a very disgraceful circumstance that such a man as So-and-so should be acquiring a large property by the most infamous and odious means, and, notwithstanding all the crimes of which he has been guilty, should be tolerated and abetted by your citizens? He is a public nuisance, is he not?" "Yes, sir." "A convicted liar?" "Yes, sir." "He has been kicked, and cuffed, and caned?" "Yes, sir." "And he is utterly dishonourable, debased, and profligate?" "Yes, sir." "In the name of wonder, then, what is his merit?" "Well, sir, he is a smart man."

Stanford Women's Basketball tickets

Owen's "Kindergarten Luck" is holding into the first grade—he won two court-level seats for the yesterday's Stanford women's basketball game. We sat right in front of the press photographers, who knelt in front us with their enviable lenses.


I tried to take photos but knew from previous experience that I wouldn't be able to take any in focus with no flash. You need a big lens for that. A super-macho lens, in fact. Got to get me one of those, clearly. Anyway—I switched to the Lensbabies gadget and got some nice impressionistic shots with that thing, which you hand-focus by pushing on the elastic thingy that the lens is mounted on.

"Blur? I embrace the blur."

Cultural Topology: an Introduction to Postmodern Mathematics


Goofy, but still interesting. At least I read it through. That's saying something.

Added later: OK—maybe I didn't read every word. I liked this:

In Physics and Beyond: Encounters and Conversations (1971), Heisenberg tells the story of his battle with tremendous hay fever that forced him to leave his studies with Max Born in May 1925. He traveled to Heligoland, hoping the sea air would ease his swollen face. Sitting on his balcony, he mused, "I had ample opportunity to reflect on Bohr's remark that part of infinity seems to lie within the grasp of those who look across the sea"(60)

Razr burn

In an inexplicable moment of weakness, I bought one of these.

I've taken a bunch of photos, but how to "send" them? Neither my "service provider" nor other possibly relevant "vendors" are much help here, including the Motorola web site itself. I'm wondering, hmmm, is the phone supposed to dial my ISP, login in, and mail the photos? Some deeply sarcophagized configuration screens—uncovered only because I, like the great Italian antiquities plunderer of the 19th century, Giovanni Belzoni, am blessed with the skill of uncovering essential items no matter how much muck and sand is piled on top of them—seem to suggest that that is indeed how it should work. Or does it send the bits over some weird phone protocol, then email it to me? Or is it supposed to work over Bluetooth? The graphics-overloaded, information-poor document that came with the phone sheds absolutely no light on these questions. It is called the "manual."

"Ah, yes, I'm simply lacking software, perhaps for my computer," I thought. But no, Motorola hasn't shipped it yet. It's "coming soon."

It's a phone that takes a good thirty seconds to regain consciousness after having been turned off. It also has a really stupid set of icons, and weird navigation, as I've already hinted. Yet everyone seems to like the phone online. "They can't ship them fast enough." I can think of a place to ship it.

Uovo di Colombo

At unovo:

In Italian, a "Unovo di Colombo" is a simple, obvious idea that doesn't occur to the person who could use it most.

I think it should be "Uovo di Colombo," instead?

Anyway, I looked for "Egg of Columbus" and found this tangram-like puzzle from the 19th century (maybe it is a Sam Loyd creation?). I also found this Tesla electrical gadget, which seems to be a levitation trick, or at least some way to demonstrate the properties of alternating current?

Someone else, writing about the origin of the term:

It recalls the story of the egg of Columbus, according to which Columbus, attending a banquet in Spain, showed how an egg could be made to stand on its end without support by cracking the shell.
