This iron pillar, part of a complex of monuments in Delhi, India, has stood for 1,600 years without rusting, despite harsh weather.
Metallurgists think it’s protected by a thin layer of “misawite”, a compound of iron, oxygen and hydrogen, that formed shortly after it was made.
Letter from Jeannette Linn to Santa Claus, Dec. 21, 1899:
Dear Santa, I thought I would drop you a few lines and tell you a few things what I want. Well, I want a pair of skates, because I think by the time Christmas comes it will be frozen up. And for another thing, I want a pair of leggings so that it will keep my feet warm and I want them so that they will come up above my shoe-tops, and I want a little slate like those that have pictures of cats and rabbits and dogs on and like those that are almost like a slate, and if it don’t cost too much I would like a large doll, so large that it would look about four years old. I will tell you where to find it. If you look in the basement of the Arcade on the place where the dolls are, you will see a large doll with real long curly hair and it is jointed and it is as pretty as I am. And I don’t think I want much, but dear Santa, I know that I want more than you can afford to give, for there are more little boys and girls and they want something too. But I would like to have so much a nice tricycle that would cost three dollars and that is too much, I think, to pay for anything, but that is really the price of it because I saw the price on it and it said $3.00 as plain as this letter is written and I think it is written pretty plain.
She finished: “Well Santa, I must close because it is getting late and I think if I don’t close you will not bring me anything. I have got as much as I can think of.”

After he’d been stung by almost everything, entomologist Justin O. Schmidt created the Schmidt Sting Pain Index, a four-point scale comparing the overall pain of insect stings:
In bloom of life
She’s snatched from hence
She had not room
To make defence;
For Tiger fierce
Took life away,
And here she lies
In a bed of clay
Until the Resurrection Day.

Robert Wallace had a noble impulse when he discovered a new species of monkey in Bolivia’s Madidi National Park. Rather than name the species after himself, he would auction off the naming rights to raise money for the park.
The marketers of the world are not so noble: $650,000 changed hands and the new species was named after an Internet casino. It’s officially called the “GoldenPalace.com Monkey.”
The largest known flying animal of all time was Quetzalcoatlus northropi, a pterosaur that flapped around Texas 80 million years ago.
Its wingspan was estimated at 39.37 feet — the length of a school bus.
Palindrome fans who lamented the closing of California’s Yreka Bakery can take heart — it’s been reopened, on the same site, as the Yrella Gallery.
One day we all set out on a tour to the Farm. Jack and Frank had gone on first, while my wife and I were as yet close to the Cave. All at once the boys came back, and Fritz said, “Look at that strange thing on its way up the path. What can it be?”
I cast my eye on the spot and cried out, “Fly all of you to the Cave! fly for your lives!” for I saw it was a huge snake, or boa, that would make a meal of one of us, if we did not get out of its way.
We all ran in doors, and put bars up to the door of the Cave. A large dove cote had been made on the roof, and to this we got up through a hole in the rock.
Ernest took aim with his gun, and shot at the snake, so did Fritz and Jack, but it gave no sign that they had hit it. I then tried my skill, but it did not seem to feel my shot any more than theirs, though I was sure I must have struck its head. Just as we took aim at it once more, we saw it turn round and glide through the reeds in the marsh.

In 1900, sponge divers were retrieving relics from an ancient Greek shipwreck when archaeologist Spyridon Stais noticed a rock with a gear wheel in it. He had discovered the Antikythera mechanism, a remarkable clockwork computer that modeled the movements of heavenly objects as early as 87 B.C.
Using x-ray analysis, historians of science and technology have studied the mechanism closely and devised several working reconstructions. British orrery maker John Gleave believes the front dial tracked the sun and moon through the zodiac year against the Egyptian calendar. Others believe it modeled the motions of the sun, the moon, Mercury, Venus, Mars, Jupiter, and Saturn — every celestial body known to the ancient Greeks.
That last interpretation is significant: In the first century B.C. Cicero had written of an instrument “recently constructed by our friend Poseidonius, which at each revolution reproduces the same motions of the sun, the moon and the five planets.” It may have been used to calculate celestial positions at the times of certain events or births.
Whatever the details, the device was remarkably sophisticated for its day: Among other things, it uses a differential gear, which historians had previously thought was invented in the 16th century. Complex Greek creations like this may have passed through the Arab world and eventually informed European clockmaking. What other ancient technology has been lost?
