20/7/2013: WLASze Part 2: Weekend Links on Arts, Sciences and zero economics

The second part of my regular WLASze (Weekly Links on Arts, Sciences and zero economics)... enjoy!

Part one is available here.



Let's start the second WLASze for the weekend we are in from science. The cognitive science to be more precise. Basically, in a summary, there's a myth that once we hit twenties, we are already matured, formed and, although conditions and our responses to them do change, we are basically 'emotional intelligence'-wise pre-determined. I am not so sure if my own recollection of my twenties supports this myth, but someone, somewhere, in large enough numbers believes it to be true. 

It turns out this is not the case (which makes me at my 45 at last being on the sane side of an argument about my own twenties). And here's an article arguing the point: "The brain is going through a second critical period of growth," she explained. "The brain doesn't finish developing until some time in your twentysomething years. Being more specific, the pre-frontal cortex doesn't reach maturation until some time in your twenties. This is the last part of the brain to have evolved; it's the last part of the brain to mature. For our purposes, what's important to know about the pre-frontal cortext is that this is the part of the brain that thinks about time, probability, and uncertainty."


Enough said. And a H/T @raluca3000 for digging the article up...


PS: I have no idea who the Girls are, but they look like something of a horror flick, where a bunch of giggly cheerleaders are about to be terrorised by a crazed alien that emerges from their mom's smile...


With alien worlds, then, here's a tale of a speedy demon: basically, someone digging through old data from that relic of the technology past that keeps on ticking - the Hubble Telescope - has spotted a little dot - a new Moon of Neptune. Quote d'resistance: “This is a moon that never sits still long enough to get its picture taken”. The thing flies around at a speed of ca 16,174 miles per hour. 

Staying with the theme of speed: ArsTechnica reports about the black hole that sucks gases at a speed of 10 million kmph or 6.21 million mph or 384 times faster than the Neptune's newest moon moves at. For those old enough to remember Ross Perot (no, not Hercule Poirot) can certainly see now where his famous reference about the 'giant sucking sound from the South' coined 21 years ago has some tangible traction... No, not in Texas, yet...



Shifting the gears from pure science (no, not Ross) to a grey area between science and arts: amasing visualisation of numbers properties: here is visualisation of π, φ and e: http://mkweb.bcgsc.ca/pi/art/


impressive visualisation h/t to Brian O' Hanlon and his comment to last week's WLASze. 

And while on the topic: progression and transition for the first 2,000 digits of e:



I have always argued that:

  1. Mathematics is a part of Art,
  2. Art is the most powerful tool of inquiry available to the (wo)mankind, and
  3. Physical sciences (beyond theory) can only aspire to possess the power of Art

Need more evidence? The above was a trip from math to art. Now, from art to math by Roman Opalka:





Moving on from the methodologised (or theorised) madness of subtle beauty, but staying with the boundary between art and science theme, here's an interesting post on the evolution of typography and design in scientific publishing. Here's an oldest (albeit not the best designed) academic journal:


Although the French as usual claim the whole thing to be their own invention (they beat the Brits to it by 3 months) with this


Thankfully, we don't have to fight this one, though the French design definitely beats the UK dysfunctional plain-face approach to jumbling together a page of text made up of some 10 fonts and about as many font sizes... 


More on history, this time - a new discovery from the Mayan civilisation. The discovery relates the tales of political battles that raged in the Dark Period (dark because we know little about it, although the entire Mayan civilisation was not exactly 'light' when it came to ethics, but...). This dates back to AD 550-560s, as my reading of the article suggests and gives us the names of two kings we didn't know about... Meanwhile in Europe Justinian's boys smuggle contraband silkworms from Asia and Black Death is all the rage across the continent... Also, rather not very light-filled years...


Silkworm was smuggled from China back in AD 553. In return, we brought Chinese art back into the fold of 'thinking art' (away from pure propaganda utilitarianism) ca AD 1980s (yep, it took that long and even as late as 1989, the Chinese Communist Party was not too keen on modern art, especially when the bosses shut down the first modern art exhibition held in China in February 1989). But as with silkworm taking hold in Europe, it will take time for art to take hold in China, although the country art scene has been hugely dynamic and original. The reason for it is that we are now into the early stages of the second generation of Chinese (resident) artists that have any capacity to think beyond the constraints of the limited vocabulary and philosophy of Communist art (Socialist Realism). 

To see this, go no further than this example of a superb online flip book of contemporary Chinese artists in Paris: http://flipbook.kohn.fr/private-sale_chine-a-paris/ Much of this is 'soft' - excitingly interesting for its novelty and naivety factors, but conceptually and artistically boring. Take numbers 10 and 11 - iconoclasm does not work in Western art context. 

Not since we broke the taboos of strictly dogmatic interpretation of the subject of art as drivers of form - the school of thought that dominated pre-Rinascimento and then occasionally re-floated under various political regimes throughout the ages, including in the 1930s-40s in fascist states and subsequently in the Warsaw Pact (plus Yugoslavia and Albania). Stuff like the above is now mostly kitsch, unless it has a historical (as opposed to artistic) value. Don't tell the fans of late (post-abstract minimalist) works of Jeff Koons:


Efforts at abstract art as well as reinterpreted traditionalist expressions represented in the e-book on Chinese art in Paris remind me of the period in Russian art around 1988-1998 when Russian artists raced to catch up with the Western vocabulary, philosophy, composition and theory, and semiotics. This process in Russian art is now exhausted, largely, although the market for Russian art still shows strong interest in that expressionist nostalgia for preservation of any departure from the past norm, even if that departure relies on the very same norm for juxtaposition-defined raison d'etre.

The entire book left me in a strange state: I would not want to hold a single work in my collection, but I would not be averse to holding many works, were I to end up with them in my collection… Strange? Try not to think too hard… the e-book is lovely... just lovely... just...


Stay tuned for Part 3 of WLASze coming up later tonight.

Nouveaux calendriers mayas : la fin du monde n'est pas annoncée...

"Les nouveaux calendriers découverts mayas n'annoncent pas la fin du monde"
Une équipe d'archéologues a déchiffré les plus anciens calendriers astronomiques mayas connus, remontant au 9e siècle.

Une équipe d'archéologues américains a mis au jour au Guatemala les plus anciens calendriers astronomiques mayas connus.  Ces derniers remontent au 9e siècle, a révélé une étude publiée ce jeudi dans la revue américaine "Science" du 11 mai et dans le numéro de "National Geographic" de juin.

Cette découverte a été réalisée dans une maison excavée sur le site de Xultun au Guatemala. Dans une des pièces de la maison, les murs sont couverts de glyphes (représentation graphique d'un signe typographique), dont un grand nombre sont des chiffres représentant des calculs liés aux différents cycles calendaires mayas. 
Il s'agit du calendrier cérémonial de 260 jours, du calendrier solaire de 365 jours ainsi que du cycle annuel de 584 jours de la planète Vénus et celui de 780 jours de Mars tandis que d'autres encore suivent les phases lunaires, précise l'archéologue William Saturno, de l'Université de Boston, qui a dirigé cette expédition et les fouilles.
Contrairement à certaines croyances populaires, il n'y a donc aucune indication dans ces calendriers que la fin du monde coïnciderait avec la fin de l'année 2012, souligne William Saturno.
"Les anciens Mayas prédisaient que le monde continuerait et que dans 7 000 ans les choses seraient exactement comme elles étaient alors", a également indiqué le scientifique.

UN HUMAIN SUR SEPT CROIT A L'IMMINENCE DE LA FIN DU MONDE

Un humain sur sept croit à l'imminence de la fin du monde

NEW YORK (Reuters) - Près de 15% des Terriens pensent faire de leur vivant l'expérience de la fin du monde, et ils sont près de 10% à penser, conformément à la prophétie maya, qu'elle pourrait se produire en décembre prochain, selon un sondage international réalisé pour Reuters par l'institut Ipsos.

Mais l'enquête, menée dans 21 pays auprès de 16.262 personnes, met en lumière de fortes fluctuations entre les nations: les Français sont les moins enclins à penser que l'apocalypse adviendra de leur vivant (6% seulement), suivis des Belges et des Britanniques (7%).
A l'inverse, ils sont 22% en Turquie et aux Etats-Unis et à peine moins en Afrique du Sud et en Argentine à penser qu'ils vivront la fin du monde.
"Qu'elle soit l'oeuvre de la main divine, d'une catastrophe naturelle ou d'un événement politique, quelle qu'en soit la raison, une personne sur sept pense que la fin du monde arrive", souligne Keren Gottfried, d'Ipsos Global Public Affairs.
"Peut-être est-ce à cause de l'attention médiatique accordée à l'une des interprétations de la prophétie maya", ajoute-t-elle.
Le calendrier maya, qui court sur 5.125 ans, s'achève le 21 décembre prochain. Pour certains, c'est le signe qu'à cette date s'achèvera aussi l'histoire de la Terre. Et pour une personne sur dix, cette prophétie maya est source d'angoisse et de peur.
Le sondage, réalisé en Afrique du Sud, Allemagne, Argentine, Australie, Belgique, Canada, Chine, Corée du Sud, Espagne, Etats-Unis, France, Grande-Bretagne, Hongrie, Indonésie, Italie, Japon, Mexique, Pologne, Russie, Suède et Turquie, souligne également que les catégories à faible niveau d'éducation, les foyers à bas revenus et les moins de 35 ans sont les plus enclins à penser qu'ils vivront l'apocalypse.
