Boeing was demonstrating its new Dash-80 airliner for the nation’s air transport executives in Seattle in August 1955 when test pilot Alvin “Tex” Johnston decided to impress them — instead of a simple flyover he performed a barrel roll:

In 1994, just before test pilot John Cashman undertook the maiden flight of the 777, Boeing president Phil Condit told him, “No rolls.”

Dinner Charge

A curious effect produced by lightning is described to us by Dr. Enfield, writing from Jefferson, Iowa, U.S. A house which he visited was struck by lightning so that much damage was done. After the occurrence, a pile of dinner plates, twelve in number, was found to have every other plate broken. It would seem as if the plates constituted a condenser under the intensely electrified condition of the atmosphere. The particulars are, however, so meagre that it is difficult to decide whether the phenomenon was electrical or merely mechanical.

Spring Poetry

From a letter by Henry U. Swinnerton of Cherry Valley, N.Y., to Science, March 10, 1893:

Towards sunset, late in April, 1886, on a warm, thawing day, the snow rapidly disappearing, two men, Capt. John E. Hetherington and Mr. Marcus Sternberg, as they rode down the long hill towards this village from the east, saw what appeared to be innumerable spherical bodies floating in the air like soap-bubbles. Both men saw and wondered at the appearance for some moments before either spoke. Capt. H. then said, ‘I wonder whether I am dreaming?’ The other rubbed his eyes and echoed the sentiment. ‘Well,’ said the captain, ‘I wonder if you see what I see; what do you see?’ They questioned each other, and both agreed as to their impressions. An orchard lay along the lower and northwesterly side of the road, and all in among the apple-trees were thick, gently descending multitudes of these bubbles, pretty uniform in size, say, 8 or 9 inches in diameter, apparently; none less than six; no small ones being observed.

The two observers state that they carefully fixed their attention on particular bubbles, in order to compare notes, and saw them seem to rest on the bough of a tree, or the top board of the fence, and then gently roll off and disappear or go out of sight. The sun was sinking and dropped below the opposite hills as they reached the foot of the long descent and entered the village, and the appearance came to an end. But up to this time the air seemed to be filled with these transparent floating spheres. The position of the observers with regard to the light seems to have made some difference as to seeing well this or that large aggregation or swarm that one or the other pointed out. The bubbles were highly colored, iridescent, gave the same sort of reflections as soap-bubbles, and apparently vanished individually in much the same way. All these points I have ascertained by repeated conversations.

Swinnerton vouches for the “unimpeachable character” of the witnesses. “The only theory I have been able to form to account for such a phenomenon is, that if a certain kind of dust floated off in the air, each particle composed of some sort of saponaceous envelope, enclosing a highly expansible centre or core, like ammonia, particles of this character expanded by the warm air, and at the same time moistened, might, under very nice conditions, produce such an effect.”

“How to Roast a Pound of Butter”

We find this culinary folly of the last century in the third edition of The Art of Cookery, by a Lady, 1748. ‘Lay it (the butter) in salt and water two or three hours; then spit it, and rub it all over with crumbs of bread, with a little grated nutmeg; lay it to the fire, and as it roasts, baste it with the yolks of two eggs, and then with crumbs of bread, all the time it is roasting: but have ready a pint of oysters stewed in their own liquor, and lay it in the dish under the butter; when the bread has soaked up all the butter, brown the outside, and lay it on your oysters. Your fire must be very slow.’

Mail Room

In the ‘London Times’ of 1841 a lady advertised in the columns of that newspaper for duplicates, which she put to a more curious use than most people. The advertisement said:– ‘A young lady being desirous of covering her dressing room with cancelled postage stamps, has been so far encouraged in her wish by private friends as to have succeeded in collecting 16,008. These, however, being insufficient, she will be greatly obliged if any good natured persons who may have these (otherwise useless) little articles at their disposal, would assist her whimsical project. Address, E.D., Mr Butt’s, Glover, Leadenhall Street, or Marshall’s, Jeweller, Hackney.’

Singing Sand

In the summarized proceedings of the September 1884 meeting of the American Association for the Advancement of Science, Trinity College chemist H. Carrington Bolton and Columbia College geologist Alexis A. Julien reported on the “musical sand” at Manchester-by-the-Sea, Mass.:

“The character of the sounds obtained by friction on the beach is decidedly musical and we have been able to indicate the exact notes on a musical staff. The shrillness and lowness of note depend chiefly on the quantity of sand disturbed; by plunging both hands into the sand and bringing them together quickly with a swoop a large quantity of the sand vibrates and we hear a tone of which the dominant note is:”

“By stroking the sand nearer the surface and with less force very high notes are heard somewhat confused. The following were heard at different times.”

“By rubbing firmly and briskly a double handful of the sand several notes on a rising scale are heard, the notes rising as the quantity of sand between the hands diminishes. We do not hear each note of the scale separately, but the ear receives an impression something like that formed by sliding a finger up a violin string at the same time that the bow is drawn.”

“The range is very remarkable and decided.”

Bolton and Julien found that “sonorous sand” was “of very common occurrence and widely distributed” — 65 of the 85 U.S. life-saving stations with which they corresponded reported that they knew of such sand. “The number is constantly increasing as the reports from keepers of life saving stations arrive.”

Overdue

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.

“A Dry Quicksand”

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.

Ruin Marble

http://commons.wikimedia.org/wiki/File:Ruinmarble.png

This brecciated limestone, quarried near Florence, has a curious property: When it’s polished it produces the image of an ancient city.

“One is amused,” wrote Parisian naturalist Cyprien Prosper Brard, “to observe in it kinds of ruins; there it presents a Gothic castle half destroyed; here ruined walls; in another place, old bastions; and what still adds to the delusion is, that in these natural paintings there exists a kind of ærial perspective, very sensibly perceptible. The lower part, or what forms the first plane, has a warm, and bold tone; the second follows it, and weakens as it increases in distance; the third becomes still fainter, while the upper part presents in the distance, a whitish zone, and finally, as it reaches the top, blends itself, as it were, with the clouds.”

In his 1832 Introduction to Mineralogy, John Comstock wrote, “At a certain distance, slabs of this marble so nearly represent drawings done in bistre, on a ground of yellowish brown, that it would be difficult to convince one to the contrary.”

Better Late

On Dec. 7, 1968, Richard Dodd of Winamac, Ind., returned a book to the University of Cincinnati medical library, noting that it was overdue.

It certainly was. The book, Medical Reports of Effects of Water — Cold and Warm — as a Remedy in Fever and Febrile Diseases, Whether Applied to the Surface of the Body or Used Internally, had been checked out by Dodd’s great-grandfather in 1823. It was 145 years late.

Dodd, whose grandfather and great-grandfather had both attended medical school at Cincinnati, had received the book as part of an inheritance. The library decided not to fine him, which is a good thing — librarian Cathy Hufford calculated that the fee would have come to $22,646.
