A Spectrum of Thoughts



Some origins

--------oOo--------

Sports bras are not as modern as one might think. Ancient female Greek athletes used a tight band of cloth known as an apodesmos over the breasts to restrict movement, making athletics a little easier. Another piece of cloth known as a strophion could be worn over the clothes, providing the same type of support as an apodesmos. Both garments were normally made of wool or linen, and they were usually tied or pinned in the back. Various statues have been found depicting the goddess Aphrodite wearing an apodesmos, leading some to believe that thinner versions may have had an erotic connotation.

Popcorn is another item that goes way back.

Corn was first domesticated 9,000 years ago in what is now Mexico, with evidence showing that the popping of corn goes back thousands of years. In Mexico, for example, remnants of popcorn have been found that date to around 3600 BC.

During the Great Depression, popcorn was fairly inexpensive at 5–10 cents a bag and became popular. Thus, while other businesses failed, the popcorn business thrived and became a source of income for many struggling farmers.

The first modern flight recorder, called "Mata Hari", was created in 1942 by Finnish aviation engineer Veijo Hietala. This black high-tech mechanical box was able to record all important aviation details during test flights of World War II fighter aircraft that the Finnish army repaired or built in their main aviation factory in Tampere, Finland. The "Mata Hari" black box is displayed in the Vapriikki Museum in Tampere, Finland.

In 1953, Australian engineer David Warren conceived a device that would record not only the instruments reading, but also the cockpit voices, when working with the Australian Research Laboratories. He built the first prototype in 1958. Local interest was nonexistent but the Poms liked it and funded developing the prototype to the airborne stage, which included a fire and shockproof case, a reliable system for encoding and recording aircraft instrument readings and voice on one wire, and a ground-based decoding device. In 1965 the units were redesigned and moved to the rear of airplanes to improve the probability of successful data retrieval after a crash.

Dr. Warren never patented his idea and received little financial reward for his invention, preferring to leave his device for airline safety throughout the world.

The term "black box" is almost never used within the flight safety industry or aviation, which prefers the term "flight recorder". The recorders are not permitted to be black in color, and must be bright orange, as they are intended to be spotted and recovered after incidents. The term "black box" has been popularised by the media in general.

Some possible explanations for the term “Black Box”:
  • That it comes from the early film-based design of flight data recorders, which required the inside of the recorder to be perfectly dark to prevent light leaks from corrupting the record, as in a photographer's darkroom.
  • That a journalist told Warren: "This is a wonderful black box." 
  • That it comes from World War II RAF jargon. Prior to the end of the war in 1945, new electronic innovations were added to planes. The prototypes were roughly covered in hand-made metal boxes, painted black to prevent reflections. After a time any piece of "new" electronics was referred to as the "box-of-tricks" (as illusionist box) or the "black box".

Thought for the Day


- George Orwell, Animal Farm

No
Original commandment
Changes
Revised commandment
1
Whatever goes upon two legs is an enemy
As the pigs become more human, they start walking on 2 legs.
Four legs good, two legs better.
2
Whatever goes upon four legs, or has wings, is a friend.
The pigs end up thinking any animal who walks on four legs or has wings is inferior. Two legs better.

3
No animal shall wear clothes.
The animals notice the pigs wearing human clothes. Napoleon is wearing a cloak.

4
No animal shall sleep in a bed.
The pigs break one of the 7 Commandments by sleeping in the bed in the farm house. They say they need to do this because their brains need more rest due to them being smarter.  Muriel checked the sign, to find it altered.
No animal shall sleep in a bed with sheets.
5
No animal shall drink alcohol.
The Pigs starts drinking alcohol
No animal shall drink alcohol to excess.
6
No animal shall kill any other animal.
When some of the animals admit to helping or being in touch with Snowball, who was exiled from Animal Farm, they were promptly slaughtered by the dogs who guarded Napoleon. The animals again thought the pigs disobeyed the Commandments but when Muriel checked them, it now read . . .
No animal shall kill any other animal without cause.
7
All animals are equal.
Ultimately, the 7 Commandments are abridged to one single phrase . . .
All animals are equal but some are more equal than others.
  



Walingford Signs




 
There is a convenience store in Seattle’s Walingford neighbourhood that has become known for its weekly signs.

This is from its website, Seattle Propane at Walingford Chevron, at:

Once per week. 4 lines. 17 characters per line.

In October of 2005 we converted our auto repair shop into an ExtraMile convenience store and suddenly we had a problem. It had always been easy to think of useful messages to put on the sign for things like service promotions and store specials and the like. But with the ExtraMile, there were no more cars to fix and the place was plastered with store specials.

So we decided to do something different.

That something different is to post signs that are witty, cheeky, flippant, philosophical and, above all, entertaining.

Following is a selection.
