Israel Siegel’s “gravity-powered shoe air conditioner,” patented in 1994, fits bellows into the heel of each of a pair of shoes, so that the natural act of walking pumps a refrigerant through two networks of heat exchange coils, one operating as a heat-absorbing evaporator and the other as a heat-delivering condenser.
Depending on how these networks are arranged, the shoe can serve as a foot cooler or a foot warmer.
A remarkable spelling trick by American magician Howard Adams:
From a deck of cards choose five cards and their mates. A card’s mate is the card of the same value and color; for example, the mate of the five of clubs is the five of spades.
Arrange the cards in the order ABCDEabcde, where ABCDE are the chosen cards and abcde are the mates. Cut this packet as many times as you like, then deal five cards onto the table, reversing their order. Place the remaining five cards beside them in a second pile.
Now spell the phrase LAST TWO CARDS MATCH. As you say “L,” choose either pile at random and transfer a card from the top to the bottom. Do the same for A, S, and T. Now remove the top card from each pile and set them aside as a pair.
Perform the same procedure as you spell TWO, CARDS, and MATCH. When you’re finished, two cards will remain on the table. Not only do these cards match, but so do each of the other pairs!
In May 1919, Canadian flying ace Mansell Richard James won an air race from Atlantic City to Boston in a $1,000 competition sponsored by the Boston Globe.
At 11 a.m. on May 29 he departed Boston to return to Atlantic City.
At 12:30 p.m. a group of picknicking schoolchildren saw his Sopwith Camel flying smoothly southward over Hancock, Ct., at an altitude of about 5,000 feet.
He was never seen again. Despite numerous rewards and extensive searching, no trace of James has ever been found.
In 2004, Livermore, Calif., paid Miami artist Maria Alquilar $40,000 to create a ceramic mural outside its new library. Its pride was short-lived: The mural misspelled the names of 10 of the 175 historical figures it honored:
Nefertite
Thesues
Michaelangelo
Shakespere
Clara Schuman
Paul Gaugan
Vincent Van Gough
Albert Eistein
German chemist Otto Beckmann’s name was spelled Beckman, and Italian sculptor Luca Della Robbia’s name was spelled Luca Della Robia.
“The most egregious is Einstein,” library director Susan Gallinger told the San Francisco Chronicle. “That’s the worst one.” Livermore is home to the Lawrence Livermore National Laboratory.
Unfortunately, California state law bars the city from removing or changing public art without the creator’s consent, so the city council had to pay Alquilar an additional $6,000 to correct the errors.
The artist was unapologetic. “The people that are into humanities, and are into Blake’s concept of enlightenment, they are not looking at the words,” she told the Associated Press. “In their mind, the words register correctly.”
Anarchist Josiah Warren believed that the only just measure of a product’s value was the amount of labor that went into producing it. Charging more than this was “cannibalism” — interest, rent, and profit were state-sanctioned usury. Accordingly, he proposed a system where goods would be traded explicitly on this basis — “he who employs five or ten hours of his time, in the service of another, receives five or ten hours labour of the other in return.”
As an experiment, Warren opened a “time store” at the corner of Fifth and Elm Streets in Cincinnati in 1827. He priced all the goods at the amount he had paid for them, plus a small surcharge to cover overhead (his books were available for inspection at the back of the store), and customers could buy goods using “labor notes” — promises to perform labor, like the one above. As he accumulated notes, Warren would redeem those that he could use and endorse the rest, using them to buy more goods, following a list of their average cost in labor. In this way he set up a small economy among like-minded citizens in Cincinnati — each received fair compensation for his labors, but none could gouge another merely because “the market would bear it.”
In like spirit, Warren charged for his own time in running the store, using a clock — if it took him half an hour to help a customer buy groceries, 25 cents would be added to the customer’s bill. “This arrangement sweeps away at once all the higgling and chaffering about prices, so disgusting in the present system, but which is inseparably connected with it,” he explained in his 1852 book Equitable Commerce.
The store operated successfully for three years, with such low prices that the competitor on the next corner asked Warren’s help in coverting his own store to Warren’s system. Warren closed the time store voluntarily in May 1830 — because, according to one account, he felt he had no claim to the increase in value of the land on which it stood.
“People think I can teach them style. What stuff it all is! Have something to say, and say it as clearly as you can. That is the only secret of style.” — Matthew Arnold
From a 1773 letter from Ben Franklin to Barbeu Dubourg:
When I was a boy, I amused myself one day with flying a paper kite; and approaching the bank of a pond, which was near a mile broad, I tied the string to a stake and the kite ascended to a very considerable height above the pond while I was swimming. In a little time, being desirous of amusing myself with my kite, and enjoying at the same time the pleasure of swimming, I returned, and loosing from the stake the string with the little stick which was fastened to it, went again into the water, where I found that, lying on my back and holding the stick in my hands, I was drawn along the surface of the water in a very agreeable manner. Having then engaged another boy to carry my clothes round the pond, to a place which I had pointed out to him on the other side, I began to cross the pond with my kite, which carried me quite over without the least fatigue and with the greatest pleasure imaginable. I was only obliged occasionally to halt a little in my course and resist its progress when it appeared that, by following too quick, I lowered the kite too much; by doing which occasionally I made it rise again.
“I have never since that time practiced this singular mode of swimming, though I think it not impossible to cross in this manner from Dover to Calais. The packet boat, however, is still preferable.”

Born in Texarkana in 1912, Conlon Nancarrow had no access to technology that could realize the music in his head. He studied music briefly and played trumpet in venues ranging from beer halls to cruise ships, but he found himself frustrated working with human musicians. In 1940 he withdrew to Mexico City, where, working in almost complete isolation, he began composing pieces for player piano.
This expedient was “a tremendous amount of work, punching all those holes by hand, one by one, hundreds and thousands of them,” but it enabled him finally to hear his music. “I’d never heard it played. Some composers are pianists and can at least play their music on piano, but I couldn’t do even that, because I am not a pianist.”
Freed from the constraints imposed by human performers, Nancarrow’s style developed a dizzying speed, staggering complexity, and a bewildering density of ideas. “Nancarrow’s complete works could be heard in seven hours,” wrote composer Kyle Gann, “but within half that time the listener would be as exhausted as though he had consumed Mahler’s ten symphonies in a gulp.”
Gyorgy Ligeti discovered some piano pieces in a Paris record store in 1980 and became an early champion, calling the composer “the greatest discovery since Webern and Ives.” Subsequent admirers included John Cage (“Conlon’s music has such an outrageous, original character that it is literally shocking”) and Frank Zappa (“The stuff is fantastic … You’ve got to hear it. It’ll kill you”).
Nancarrow became a MacArthur fellow in 1982 and returned to writing for live ensembles, finding that the standard of musicianship had improved enormously during his 40-year exile. “Of course it’s pleasing,” he told the New York Times in 1987. “I mean, all those years I had been working now have some point. There are so many artists and writers who are doing something they think is worthwhile, and it turns out to be junk. I thought that maybe mine was the same thing, but now I see it wasn’t.”

In the southwestern corner of the desert of southern Arabia, north of the western end of Hadramaut, and approached from the little village of Sawa, is a very remarkable spot described by Wrede from his visit in 1843, whose description is reproduced in a recent number of the Revue coloniale internationale. There are here, in the waste of yellow sand, several spots covered by a grayish white dust, which swallow up every object thrown into them. One of these spots, described by Wrede, is about two miles long and a little less in breadth. It sinks gradually toward the middle and is apparently due to the work of the wind. Wrede approached it with the greatest care and sounded it with his staff. The edge is stony and falls away suddenly. When the staff was thrust into the fine material beyond the edge, almost no resistance was felt and it was as if the staff had been thrust into water. When it was passed through the fine dust lengthwise the resistance was almost imperceptible. A stone of two pounds weight or more was fastened to a cord sixty fathoms long and thrown in as far as possible. It sank at once and with increasing velocity so that at the end of five minutes the end of the cord had disappeared. The presence of Bedouins prevented any more observations. The natives believe that great treasures are buried here and are watched over by genii who pull down into the depths the unwary treasure-seeker.
