Hair Tomorrow

http://www.google.com/patents/US4932098

In 1990, as the length of manned space missions began to increase dramatically, NASA’s Richard Haines began to wonder: On an extended mission, how could crew members groom themselves without leaving bits of hair and beard floating about the cabin?

His solution was a clear plastic bubble fitted with slits for a groomer’s hands, as well as a vacuum hose. The same apparatus can be used for almost any grooming task, including haircuts, shaving, and manicures.

“The device may also be used to collect the aerosol droplets of hair spray or small powder residue and the residue of other cosmetics which otherwise would float freely throughout the cabin.”

Many a man floated in water before Archimedes; apples fell from trees as long ago as the Garden of Eden, and the onrush of steam against resistance could have been noted at any time since the discovery of fire and its use under a covered pot of water. In all these cases it was eons before the significance of these events was perceived. Obviously a chance discovery involves both the phenomenon to be observed and the appropriate, intelligent observer.

Brothers in Binary

A number is said to be perfect if it equals the sum of its divisors: 6 is divisible by 1, 2, and 3, and 1 + 2 + 3 = 6.

St. Augustine wrote, “Six is a number perfect in itself, and not because God created all things in six days; rather the converse is true; God created all things in six days because this number is perfect, and it would have been perfect even if the work of the six days did not exist.”

Perfect numbers are rare. No one knows whether an infinite quantity exist, and no one knows whether any of them are odd. The early Greeks knew the first four, and in the ensuing two millennia we’ve uncovered only 44 more. But they have one thing in common — they reveal a curious harmony when expressed in base 2:

“Winter Eve”

Drear fiend: How shall this spay be dent?
I jell you no toque — I do not know.
What can I do but snatch the woe
that falls beyond my pane, and blench
my crows and ted my briny shears?
Now galls another class. I’ll sit
and eye the corm that’s fought in it.
Maces will I fake, and heart my pare.
Is this that sold elf that once I was
with lapped chips and tolling lung?
I hollow sward and tight my bung
for very shame, and yet no cause —
save that the beery witchery
of Life stows grail. Shall I abroad?
Track up my punks? Oh gray to pod
for him who sanders on the wee!
I’ll buff a stag with shiny torts
and soulful hocks, a truthbush too,
perhaps a rook to bead — but no!
my wishes must be dashed. Reports
of danger shake the reaming scare.
Whack against blight! Again that tune,
“A gritty pearl is just like a titty prune”
blows from the fox. I canot bear
this sweetness. Silence is best. I mat
my mistress and my sleazy lumber.
I’ll shake off my toes, for they encumber.
What if I tub my stow? The newt
goes better fakèd to the cot.
I’ll hash my wands or shake a tower,
(a rug of slum? a whiskey sour?)
water my pants in all their plots,
slob a male hairy before I seep —
and dropping each Id on heavy lie,
with none to sing me lullaby,
slop off to dreep, slop off to dreep.

— Robert Morse, quoted in W.H. Auden’s commonplace book A Certain World

“We have not the reverent feeling for the rainbow that a savage has, because we know how it is made. We have lost as much as we gained by prying into that matter.” — Mark Twain

“At last I fell fast asleep on the grass & awoke with a chorus of birds singing around me, & squirrels running up the trees & some Woodpeckers laughing, & it was as pleasant a rural scene as ever I saw, & I did not care one penny how any of the beasts or birds had been formed.” — Charles Darwin, letter to his wife, April 28, 1858

Greetings

http://www.scribd.com/doc/48771623/Lageos-Press-Kit

Launched in 1976, NASA’s Laser Geodynamic Satellite needed a stable orbit to permit precise measurements of continental drift, so its designers gave it a high trajectory and a heart of solid brass. As a result, it’s not expected to return to Earth for 8 million years. That raised an interesting challenge: What message could we attach to the satellite that might be intelligible to our descendants or successors, who might recover it thousands of millennia in the future?

Tasked with that problem, Carl Sagan came up with the “greeting card” at left, which is affixed to LAGEOS on a small metal plaque. Using it, whoever comes upon the plaque can calculate roughly the time between his own epoch and ours. In Sagan’s words, the card says, “A few hundred million years ago the continents were all together, as in the top drawing. At the time LAGEOS was launched the map of the Earth looks as in the middle drawing. Eight million years from now, when LAGEOS should return to Earth, we figure the continents will appear as in the bottom drawing. Yours truly.”

Morality turns on whether the pleasure precedes the pain or follows it (provided it is sufficient). Thus, it is immoral to get drunk because the headache comes after the drinking, but if the headache came first, and the drunkenness afterwards, it would be moral to get drunk.

Balance

rectangle theorem

For any rectangle, the sum of the squares of the distances from any point P to two opposite corners is equal to the sum of the squares of the distances from that point to the two other corners (so, above, a2 + c2 = b2 + d2). This remains true whether the point is inside or outside the rectangle, on a side or a corner, or even outside the plane.

Pushkin wrote, “Inspiration is needed in geometry, just as much as in poetry.”

Plane Dealing

A pilot is about to depart in his plane when he meets a young woman on the airport concourse. She has missed her flight.

“I can give you a lift if you like,” he says.

“But you don’t know where I’m going,” she says.

“It doesn’t matter. I can drop you off wherever you like and continue to my destination without going out of my way.”

This seems preposterous until he explains where he’s going. Where is it?

Surface Mail

On Christmas night 1945, Army serviceman Frank Hayostek tossed a bottle over the rail of the troopship that was carrying him home from France. It contained this message:

Dear Finder,

I am an American soldier … 21 years old … just a plain American of no wealth, but just enough to get along with. This is my third Christmas from home. … God bless you.

In September 1946, he received a letter from Ireland:

I have found your bottle and note. I will tell you the whole story.

I live on a farm at the southwest coast of Ireland. On Friday, Aug. 23, 1946, I drove the cows to the fields beside the sea and then went for walk on the strand called The Beal. It is an inlet of Dingle Bay.

Well, my dog was running before me and I saw him stop and sniff something light on the sand, and then he went off in pursuit of sea gulls. I found the object was a brown bottle. … The cork … crumbled in my fingers. How the note kept dry, nobody can understand. … I sat there on the beach and read it.

I thought at first I was dreaming. This is just a little common Irish village where nothing strange ever occurs, and this is something for the farmers to talk about while they cut the oats and bring the hay into the barn. Well, imagine, the bottle has been on the sea for eight months. … Who knows where it has been? It may have traveled around the world. How did it escape being broken on the rocks? If you had only seen where I got it! It’s all a mess of rocks. The hand of Providence must surely have guided it.

Well, I hope to hear from you soon. … You mention offering no reward to the finder of the bottle. Well, I ask no reward, as it was a very pleasant surprise. Wishing you very good luck, your loving friend,

Breda O’Sullivan

Hayostek and O’Sullivan exchanged 70 letters over the next seven years. She was a farm girl in the village of Lispole in County Kerry, and he found work as a welder in Johnstown, Pa., saving $80 a month in order to visit her.

In August 1952 Hayostek flew to Ireland, where both were besieged by reporters.

“It’s in the hands of God,” he said. “She’s very nice.”

“After all,” she said, “we only met a few hours ago. Up to then, he was only a man in a bottle.”

But after two weeks O’Sullivan announced, “There is no romance and there will be no wedding. We will remain good pen pals.” She continued to correspond with Hayostek until 1959, when she married a local man. “If I had known that I would get all that publicity by answering the letter,” she told a reporter later, “I would have left the bottle lying there.”

Hayostek may have felt differently. His gravestone reads: “Frank L Hayostek, June 11, 1924-November 15, 2009: Frank Hayostek met in Tralee, Ireland, with Breda O’Sullivan who found a message-laden bottle he had tossed from a Liberty ship seven years before.”
