Pain is just an oil away

From wired,it now happens that nerves may transmit information using a mechanism akin to sound waves,not electric signals! Since olive oil is similar to the lipid molecules that make up nerve cells,Jackson and Heimburg started questioning the generally accepted belief that anesthetics block electrical pulses by fitting themselves into pain receptors on [...]

lolcats,communities and emergence

Anil says that lolcats has grammar,and in doing so points to the most important characteristic of those anthropomorphized felines:There’s a consistent visual vocabulary to the construct,as well. If it ain’t Impact or Arial Black or some other nondescript sans serif font,it ain’t lolcat. White letters with a black outline are a [...]

Chaos markets

Do some trading using your computer:All such methodologies fall under the catch-all title of technical analysis,the subject of countless books,newsletters and “how-I-got-rich”infomercial testimonials. The central idea —reducing securities markets to mathematically crunchable datasets that can be objectively analyzed —is as old as trading itself.

Finally,a way to put [...]

Virtual disease

You can get infected now in those virtual worlds:Wonderland informs of a disease attacking people in WoW,and spreading through contact to other towns and players,even killing the weaker ones. In a complex environment it was bound to happen that,at some point,the rules would allow this to happen. And then the [...]

Epidemiology and scale-free networks

On a epidemiologic simulation using a virtual Portland,the results point to the conclusion that the best solution to deal with the transmission of the disease is speed of implementation of measures:The actual response strategy chosen made little difference compared with the time element.

Which of course makes me think that in any scale-free [...]

Les Rues de Bogota

From a study published in Nature,a model of Bogotá’s jam-free streets explains that aggressiveness is good for you. Sort of:

Traffic experts had previously been puzzled as to how Bogotá,with 7 million inhabitants and more than a million private cars,is so jam-free. The answer now seems that Bogotáns are simply more aggressive than their counterparts in London,New York and other huge metropolises.

And here is the link to the preprint.

Of course,now it makes sense! If you read Salon article about second generation traffic calming,mentioned by Jason Kottke,the emphasis is not on speed,nut on the limitation of the drivers’behavior,as everyone learns to accept the presence of the others.
In Bogotá,the study,that aggressiveness yields one of the highest fatality rates in the world,being in fact one of every six violent deaths caused by traffic accidents. Mind you,we are talking Colombia here.
They could use some traffic calming there.
I leave you with the famous Les Rues de Bogotá,par Rocca:
Bogota Me amenaza,donde todo te pasa
Ville ou ruisselle le sang,la flaca pasa por mi casa
Ou à chaque faux mouvements
Tout tombe si subitement
Les balles sifflent comme le vent
“Si da papaya”,reste sur le firmament étendu
Personne n’a rien vu,encore moins entendu
Ici la rue,c’est presque une cause perdue
Les avenues silencieuses,“paila”trop douteuses
Fixent comme une mitrailleuse les passants
La misère creuse,on règle ses comptes en plein jour
Rien à foutre,il n’y a plus d’amour
Il n’y a qu’un seul dieu,qu’un seul parcours
Si la mort vient vers toi,cours
On vit l’instant présent,on le vit à 100%
Dehors on blague,on rit de tout,on défie même le temps
Quand vient le soir,les rues s’éteignent,les vampires sortent
On danse avec la mort,jusqu’à ce que l’aube l’emporte
Les chargeurs vident se remplissent à nouveau
Encore un jour qui commence un peu tôt

Paid journals

Looking for Chaos I got to the website of the AIP Chaos journal,and from what I cold gather they have interesting articles. That is,from outside,because oh surprise,they charge a steep subscription for that! What is the idea? Oh,I get it:Barriers to knowledge,we just don’t want anybody getting ideas [...]

Julia

Pacific Views made me go and check the google logo for today,the birthday of scientist Gaston Julia. When Mandelbrot enthralled everybody with his sets and the like,a few of us,experimenting with Fractint found that every point in the set corresponded to a Julia graph. I used to study this,so you would [...]
