Des friction lights de John Walker aux lucifers de Samuel Jones
Le pharmacien John Walker est celui qui a inventé, en 1827, la première allumette qui s’allume par friction, comme on la connaît aujourd’hui. S’inspirant des travaux d’un physicien et chimiste irlandais, Robert Boyle, il imagine un mélange qui, par friction sur une surface rugueuse, peut s’enflammer. En bon scientifique qu’il était, et ne voulant pas faire connaître le procédé de sa découverte, il refuse de la breveter, se contentant de commercialiser lui-même son produit, et de vaquer à ses occupations de pharmacien, botaniste et minéralogiste. Ce procédé de fabrication des allumettes finit par être breveté sous le nom de lucifers par un certain Samuel Jones. Les lucifers présentaient néanmoins de nombreux problèmes : flamme instable et violente, odeur désagréable. On dit que malgré tous ces désagréments, le nombre de fumeurs augmenta en raison de cette invention. Ils pouvaient enfin déambuler dans la nature, avec leurs cigarettes, cigares et pipes, en toute indépendance.
From John Walker's Friction Lights to Samuel Jones' Lucifers
In 1827, the pharmacist John Walker invented the first friction-lighting match, as we know it today. Inspired by the work of an Irish physicist and chemist, Robert Boyle, he imagined a mixture that could ignite by friction on a rough surface. As a good scientist, and not wanting to make the process of his discovery known, he refused to patent it, contenting himself with marketing his product himself, and going about his business as a pharmacist, botanist and mineralogist. This process for manufacturing matches ended up being patented under the name of Lucifers by a certain Samuel Jones. However, Lucifers presented many problems: unstable and violent flame, unpleasant odor. It is said that despite all these inconveniences, the number of smokers increased because of this invention. They could finally wander around in nature, with their cigarettes, cigars and pipes, in complete independence.

A match is a tool for starting a fire. Typically, modern matches are made of small wooden sticks or stiff paper. One end is coated with a material that can be ignited by frictional heat generated by striking the match against a suitable surface. Wooden matches are packaged in matchboxes, and paper matches are partially cut into rows and stapled into matchbooks. The coated end of a match, known as the match "head", consists of a bead of active ingredients and binder; often colored for easier inspection. There are two main types of matches: safety matches, which can be struck only against a specially prepared surface, and strike-anywhere matches, for which any suitably frictional surface can be used.
Historically, the term match referred to lengths of cord (later cambric) impregnated with chemicals, and allowed to burn continuously. These were used to light fires and fire guns (see matchlock) and cannons (see linstock). Such matches were characterised by their burning speed i.e. quick match and slow match. Depending on its formulation, a slow match burns at a rate of around 30 cm (1 ft) per hour and a quick match at 4 to 60 centimetres (2 to 24 in) per minute.
The modern equivalent of this sort of match is the simple fuse, still used in pyrotechnics to obtain a controlled time delay before ignition.The original meaning of the word still persists in some pyrotechnics terms, such as black match (a black-powder-impregnated fuse) and Bengal match (a firework akin to sparklers producing a relatively long-burning, coloured flame). But, when friction matches became commonplace, they became the main object meant by the term.
The word "match" derives from Old French "mèche" referring to the wick of a candle.
Early matches
A note in the text Cho Keng Lu, written in 1366, describes a sulfur match, small sticks of pinewood impregnated with sulfur, used in China by "impoverished court ladies" in AD 577 during the conquest of Northern Qi.[5] During the Five Dynasties and Ten Kingdoms (AD 907–960), a book called the Records of the Unworldly and the Strange written by Chinese author Tao Gu in about 950 stated:
If there occurs an emergency at night it may take some time to make a light to light a lamp. But an ingenious man devised the system of impregnating little sticks of pinewood with sulfur and storing them ready for use. At the slightest touch of fire, they burst into flame. One gets a little flame like an ear of corn. This marvelous thing was formerly called a "light-bringing slave", but afterward when it became an article of commerce its name was changed to 'fire inch-stick'.
Another text, Wu Lin Chiu Shih, dated from 1270 AD, lists sulfur matches as something that was sold in the markets of Hangzhou, around the time of Marco Polo's visit. The matches were known as fa chu or tshui erh.

Day 3 of 20 of albums that influenced my musical tastes.
I would like to dedicate this photo to one of my first and true friends here in Flickr. I've met Ian Sane
www.flickr.com/photos/31246066@N04/ like 15 years ago, when I discover a similar taste for cats, then for music, and music. Levi was one of those cats, a beautiful and regal cat, and even its paw was Kurt's profile picture.

Day 3 of 20 of albums that influenced my musical tastes.
Let It Be is the twelfth and final studio album by The Beatles. It was released on 8 May 1970, nearly a month following the official announcement of the group's public break-up. Concerned about recent friction within the band, Paul McCartney had conceived the project as an attempt to reinvigorate the group by returning to simpler rock 'n' roll configurations. McCartney said he had the idea of the song "Let It Be" after he had a dream about his mother during the tense period surrounding the sessions for The White Album in 1968. Mary Patricia McCartney died of cancer in 1956, when he was fourteen. McCartney later said: "It was great to visit with her again. I felt very blessed to have that dream. So that got me writing 'Let It Be'." In a later interview, he said about the dream that his mother had told him, "It will be all right, just let it be." (from Wikipedia)
This is maybe my 2nd or 3rd favorite Beatles album, but I remember that I listened a lot at home when I was a child. I love its raw sound, without all the orchestral and experimental sounds, setting the basis for the 70s and 80s rock music.

I have been struggling to find older photos that I still want to share. I have taken some new, but have shared all of them that I'd like to (for the most part). So now I dip back into the archives to find something I've missed.
And so there's this. I've shared a color photo of this a long time ago, but here is the black & white version. That's not to say they're the same photo. Each uses a different lens and camera position.
This weekend I hope to take more. I'm trying to not be so broad in my photography. I don't really want to do macro, but perhaps something closer. Something I haven't noticed before. Or something I've noticed but haven't photographed. And there's more to come as well. You'll see.

(Image 4 of 7) The following group of images shows various stages of space shuttle external tank assembly at NASA's Michoud Assembly Facility in New Orleans. Previously, the liquid hydrogen tank barrels were fabricated using traditional fusion welding. Friction stir welding is different in that the materials are not melted. A friction stir weld tack tool is used to tack weld barrel panels together prior to the full penetration weld. A rotating tool pin uses friction and applied pressure to plasticize the metal and join the 20-foot longitudinal panels together. As a result, weld joints are more efficient, yielding 80 percent of base material strength.

Large friction plastic model/toy. Made in Hong Kong is all its marked. Nicely detailed though. 10"long 3"high. Was a bit 'worn/played with' when I got it but have tried to restore it (paintwork/decals) best I can.
I made a fink version of my buddy Tiny, of Tiny's Chop & Kustom Shop, Friction In The Static radio show/podcast, Traditional Rod & Kulture Illustrated magazine, and Diehards TV show....that boy gets around!
The original was drawn in pencil on 100lb bristol vellum paper, inked with ceramic tipped pigment pens, then I photographed it with my 5D Mark II (too big for my scanner) and brought it into Photoshop for colors, textures, and a few little touch ups.
....and so my Fink obsession continues....
