Pull Over

Americans measure distance in football fields and stones’ throws.

Finns measure it in poronkusema (literally, “passing of water of reindeer”). One poronkusema is the distance a reindeer can pull a sleigh between stops to urinate. It’s 8-10 kilometers, or about five miles.

Need a velocity measure? Poronkusemaa kuukaudessa (poronkusemas per month) is about 0.0289252 meters per second, or 40 feet per hour. Evidently things don’t move fast in Finland.

“The Fuels of the Future”

“With the prospect of coal becoming as rare as the dodo itself, the world, we are told by scientists, may still regard with complacency the failure of our ordinary carbon supply. The natural gases and oils of the world will provide the human race with combustible material for untold ages — such at least is the opinion of those who are best informed on the subject.”

Glasgow Herald, quoted in Scientific American Supplement No. 717, Sept. 28, 1889

Platypus

When he received the first duck-billed platypus from Captain John Hunter in Australia, naturalist George Shaw thought it was a hoax. “Impossible not to entertain some doubts as to the genuine nature of the animal, and to surmise that there might have been practised some arts of deception in its structure,” he wrote in the journal Naturalist’s Miscellany.

Surgeon John Knox agreed: “Aware of the monstrous impostures which the artful Chinese had so frequently practised on European adventurers … the scientific felt inclined to class this rare production of nature with eastern mermaids and other works of art.”

“Quake Hairs”

From a Scientific American account of a Thai earthquake on May 13, 1848:

During the shock, there spontaneously came out of the ground a species of human hairs in almost every place — in the bazaars, in the roads, in the fields, and the most solid places. These hairs, which are pretty long, stand upright and adhere strongly to the ground. When they are burned, they twist like human hairs and have a burned smell which makes it to be believed that they are really hairs; they all appeared in the twinkling of an eye during the earthquake. The river of Chantibun was all rippling, and bubbles rose to the surface, so that the water was quite white. It is thought that these hairs may have been produced by electricity.

Similar “hairs” have been reported after other Asian earthquakes. Some have been identified as fibers from the hemp palm Chamaerops fortunei, a native tree. Others remain unexplained.

The Flynn Effect

Are we getting smarter? IQ scores around the world have been going up by about three IQ points per decade.

Suggested reasons include improved nutrition, smaller families, better education, and the stimulating modern environment, but no one really knows what’s causing it.

It’s called the Flynn effect, after New Zealand political scientist who discovered it.

“The Planet of War”

The land regions of Mars can be distinguished from the seas by their ruddy color, the seas being greenish. But here, perhaps, you will be disposed to ask how astronomers can be sure that the greenish regions are seas, the ruddy regions land, the white spots either snow or cloud. Might not materials altogether unlike any we are acquainted with exist upon that remote planet?

The spectroscope answers this question in the clearest way. You may remember what I told you in October, 1876, about Venus, how astronomers have learned that the vapor of water exists in her atmosphere. The same method has been applied, even more satisfactorily, to the planet of war, and it has been found that he also has his atmosphere at times laden with moisture. This being so, it is clear we have not to do with a planet made of materials utterly unlike those forming our earth. To suppose so, when we find that the air of Mars, formed like our own (for if it contained other gases the spectroscope would tell us), contains often large quantities of the vapor of water, would be as absurd as to believe in the green cheese theory of the moon, or in another equally preposterous, advanced lately by an English artist — Mr. J.T. Brett — to the effect that the atmosphere of Venus is formed of glass.

Science Marches On

Thinking they had found a Viking settlement, a team of experts spent months in 2003 excavating a platform of slabs in Marion Garry’s garden in Fife, Scotland.

They finally realized it was a patio from the 1940s.

Archaeologist Douglas Speirs admitted to ignoring an old television remote found during the dig.

“Looking back now,” he said, “that probably wasn’t the best approach.”
