Whoah

Vulcanize-Charles Goodyear and the Roman god of Fire

The early nineteenth century saw tremendous advances in chemistry, with scientists leading teams all across the world to improve both science in general and industrial processes in particular.  Leading the charge to improve rubber compounds was Charles Goodyear (born on this day, December 29, 1800, died July 1, 1860) who devoted his life and health to improving rubber compounds.  Self taugh Goodyear ran a hardware store in Philadelphia and realized early that improved rubber goods would transform manufacturing.

He toyed with the chemistry of rubber manufacturing for two decades before hitting upon heating the rubber as the most important part of the process by accident.  He was awarded a patent for vulcanizing rubber in 1844 for his efforts, though he still did not fully understand the process or what exactly was happening.  Enduring backruptcy, jail, and personal tragedy, Goodyear died at the age of 59, collapsing at the news of his daughter’s death and never recovering.  

The verb vulcanize was coined between 1820-1844 (several disputed dates are offered) to describe the process of changing something by adding heat or fire, from Vulcan, the Roman god of Fire.  By 1846, the word was in wide circulation thanks to Goodyear’s patent.  The company that bears his name today was actually founded almost 40 years after his death in honor of his contributions to the science of rubber compounds but also to capitalize on his fame and reputation.  Etymologically, the name Vulcan (Volcānus or Vulcānus) has unclear origins.  Some liguists connect the name with the Cretan god Velchanos, while others dispute this with no clear etymology.  Vulcan’s earliest temple in Rome dates to 8th century BCE.

y’alllllllllllllllllllllllllllllll there’s a children’s book

USADance (and I’m assuming the national organizations for other countries) still do this! The local chapters have to hold dances, and at least one of those a year has to be a formal: http://usadance.org/chapters/find-a-local-chapter/

You know what I wish we still had? Balls.

Like formal balls from fairytails. Instead of going to a club or a bar, you would go to a ballroom. There’d be music and dancing, and everyone could wear fancy clothes. There could be masquerades, where you could meet new people and reveal your real identity at the end of the night. There could be gay/lesbian balls and gothic balls and space fantasy balls. Just, formal balls. 

Huh, it’s almost as if diversity in backgrounds/abilities results in greater diversity of thought

De-automation is a thing | Robohub

We tend to assume that automation is a process that continues – that once some human activity has been automated there’s no going back. That automation sticks. But, as Paul Mason pointed out in a recent column that assumption is wrong.

Mason gives a startling example of the decline of car-wash robots, to be replaced by, as he puts it “five guys with rags”. Here’s the paragraph that really made me think:

“There are now 20,000 hand car washes in Britain, only a thousand of them regulated. By contrast, in the space of 10 years, the number of rollover car-wash machines has halved –from 9,000 to 4,200.”

The reasons, of course, are political and economic and you may or may not agree with Mason’s diagnosis and prescription (as it happens I do). But de-automation – and the ethical, societal and legal implications – is something that we, as roboticists, need to think about just as much as automation.

Several questions come to mind:

are there other examples of de-automation? is the car-wash robot example atypical, or part of a trend? is de-automation necessarily a sign of something going wrong? (would Mason be so concerned about the guys with rags if the hand car wash industry were a well-regulated industry paying decent wages to its workers, and generating tax revenues back to the economy?)

Showed this to some friends, it almost seems to be along religious lines?

Burial vs Cremation in the United States

Most of that is the same in the US, though we have slightly different divisions, and more dances because of the Arthur Murray-standardized American Style. I’m just a collegiate Silver Standard dancer, though someone please correct me if I’m off, and I’ll barely mention Open.

Dance Styles: International Standard (Waltz, Tango, Foxtrot, Quickstep, Viennese Waltz), International Latin (Cha cha, Rumba, Samba, Jive, Paso Doble), American Smooth (Waltz, Tango, Foxtrot, Viennese), and American Rhythm (Cha cha, Rumba, Swing, Mambo, Bolero). The biggest difference between Standard and Smooth is that the couple can break frame in Smooth.

Divisions: There’s really two sets of divisions: Syllabus and Open. Syllabus divisions have specific figures they can do at their level, and go Newcomer, Bronze, Silver, Gold (or Newcomer, Beginner, Intermediate, and Advanced). Open has less restrictions on figures, essentially follows Syllabus once Gold starts to get boring, and goes Novice, Pre-Champ, Champ. USADance has also created Same-Sex divisions separated by gender of pairing and Open vs. Syllabus (these divisions would have Newcomer couples compete against Gold-level couples), but in collegiate competitions these couples are not separated out from the rest. For the most part the next division is achieved by points, but Newcomer at all competitions and Bronze at some collegiate competitions are also determined by time. 

The number of dances you compete per style increases as you ascend levels as dances become paired, though some like Viennese Waltz and Paso Doble are typically separated out on their own. Same-Sex dances are currently not paired.

Costumes are pretty much the same, though there isn’t a standard for non-traditional dance roles. I’ve seen lady leaders do black tops and leotards with either pants or skirts, and male follows typically follow leader costume rules.

Ballroom

@carmodance for your anon and for other dance fans who knows nothing about ballroom

I saw a lot of people asking about ballroom, so I’ll try to explain few things (it’s gonna be long).

I’m from Russia and I didn’t compete last 4 years, so rules maybe slightly different. Also I probably forgot a lot of things. And my english isn’t the best.

Read it all under the cut
