Ulam Spiral

As a mathematical mainframe to design the volumetric base of Instants of Metamorphosis v.01, we have the Ulam Spiral. The installation will be presented at the ABCIBER 2011 conference and exhibition next November in Florianopolis, Brazil:

Observations on the Regularity of Prime Number Distribution
by Peter Marteinson
http://french.chass.utoronto.ca/as-sa/ASSA-No14/article7en.html

Abstract:
Stanislaw Ulam’s (1964: 516) most general observation on his famous spiral, that a “property of the visual brain” allows patterns relating to the characteristics of primes to be discovered, may indeed stimulate the mathematical imagination, and inspire further creative attempts at visual pattern recognition in this area, but his spiral (fig.1), like its derivatives, has yet to be successfully interpreted in terms of possible arithmetic principles that can explain the genesis of the known distribution of prime numbers. Of his spiral he says only that it “appears to exhibit a strongly nonrandom appearance” (Stein et al. 1964). A corollary of this somewhat disappointing observation is that Euler’s pessimistic prognosis has yet to be disproved: “Mathematicians have tried in vain to this day to discover some order in the sequence of prime numbers, and we have reason to believe that it is a mystery into which the mind will never penetrate” (cited by Ivars Peterson in Science News, 5/4/2002). The Encyclopædia Britannica (2004) continues to suggest this consensus is alive and well, referring in an article entitled “Elementary Number Theory” to “the irregularity in the distribution of primes” which “suggests that there is no simple formula for producing all the primes.”

Research Project - Learning about Wonderland

This month we have two invited temporary members who started working with The Double Collective to develop part of their undergrad research project I'm supervising - Erica Monteiro and Flavio Santos. They will be involved in the production of Instants of Metamorphosis v.03 including the managing of the 3D online shared environment, aim in to produce a theoretical reflection about the creative process itself from a metapoint of view (Edgar Morin, 1977).

First of all, they have to learn about the Open Wonderland Platform. Here we have a few tips:

Rashomon Effect

Last Monday I was talking with a new friend (Milena Zafir) about the structural similarities between the church and the academy. She suggested me to read "Michel Foucault – from “The Order of Discourse” (Michel Foucault, from “The Order of Discourse” R. Young, ed. Untying the Text (1971). We were in a garden, talking and drinking beer after a frustrating talk of Don Buchla, at the School of Communications and Arts, University of Sao Paulo. I was reading the small book today while traveling form Sao Paulo to Limeira.

Foucault was talking about discourse, truth.

Googling "Rashomon effect", I selected a few references, including the trailer of the film "Rashomon" (Akira Kurosawa, 1950)and an interesting paper of two Harvard University researchers:




The Rashomon Effect: Combining Positivist and Interpretivist Approaches in the Analysis of Contested Events. by WENDY D. ROTH and JAL D. MEHTA
Harvard University
Abstract:
Positivist and interpretivist analytical approaches are frequently believed to be incompatible as research strategies and ways of understanding the world. This article argues that not only may versions of positivism and interpretivism be combined in the analysis of contested events, but this combination can further the goals of both approaches by contributing information that may have been missed by adopting only one perspective. The authors illustrate this using two case studies of lethal school shootings near Paducah, Kentucky, and Jonesboro, Arkansas, and introduce methodological strategies to manage potential biases that may lead to contradictory testimony. However, these same contradictions act as distinct data points from the interpretivist perspective, offering insight into the cultural understandings of a community. The authors develop new forms of triangulation that are tailored to these research goals and illustrate how, just as positivist analysis may be used to aid interpretivism, an interpretive understanding of a community may be necessary to develop causal theories of contested events such as school shootings.

The following form will be used at the Voodoohop to run the dynamic of collecting antenarratives:

Instantes de Metamorfose I
Voodoohop, 21 Janeiro de 2011, São Paulo

Dinâmicas de desenho e escrita emergente são a base do processo de colecionar/construir os espaços estoricizados. A coleção de espaços estoricizados objetiva tornar visível a dinâmica sistêmica. É a partir dessa coleção de espaços estoricizados que é possível construir novas narrativas observando as relações entre as partes, entre partes e todo, entre todo e ambiente. Os espaços estoricizados serão agrupados em 7 (sete) instâncias de organização e significado em uma estrutura que é um sistema dentro do sistema-processo criativo. As instâncias são – impressão, atenção, memória, comparação, julgamento, reflexão, e imaginação e a dinâmica contempla as seguintes etapas:
1) Impressão (desenhos emergente produzido imediatamente após a experiência)
2) Atenção (escrita emergente produzida 10 minutos após a experiência e/ou gravação de vídeo com depoimento na forma de brainstorming)
3) Memória (escrita emergente e/ou desenho produzidos 1 (um) dia após a experiência)
4) Comparação (escrita emergente produzida 2 (dois) dias após a experiência combinada com a produção de um painel semântico)
5) Julgamento (escrita emergente produzida 3 (três) semana após a experiência)
6) Reflexão (escrita emergente produzida 5 (cinco) dias após a experiência)
7) Imaginação (escrita emergente e desenho produzidos 7 (sete) dias após a experiência)
