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.

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.

Excerpt from en.wikipedia.org/wiki/Bukchon_Hanok_Village:
Bukchon Hanok Village is a residential neighborhood in Jongno District, Seoul, South Korea. It has many restored traditional Korean houses, called hanok. This has made it a popular tourist destination, which has caused some friction with the residents who live there.
The area of Bukchon, which consists of neighborhoods: Wonseo-dong, Jae-dong, Gye-dong, Gahoe-dong and Insa-dong, was traditionally the residential quarter of high-ranking government officials and nobility during the Joseon period. It is located north of the stream Cheonggyecheon and Jongno, hence named Bukchon, which means north village.
(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.
love this scene showing the opposites, steel against nature....ofcourse steel is also nature but a bit harsher ;)
