Tool for the visualization of historical data (Chronologies)


  1. In page 563 in paragraph 1 the sentence “In recent years, research in the humanities have started to …” should be: “In recent years, researchers in the humanities have started to …
  2. In page 563 in paragraph 2 the sentence ” … because there is no way to intervene from outside the way how the program process and render the data.” should be: “… because there is no way to intervene from outside the way how the program processes and renders the data.

What is a Machine?

B17 Bomber Belly

B17 Bomber Belly. ca.1939

A machine is that which behaves in a machine-like way, namely, that its internal state, and the state of its surrounding, defines uniquely the next state it will go [1, p.261].

Thus, the material or materials from which a machine is made becomes irrelevant. As the machine becomes a function of internal and external states.

Vocoder (Voice Coder)

This is a short media history of technical sound coding and distortion, from the military scrambling of speech through the robotic sounds of Kraftwerk to today’s linear predictive coding burned into mobile phones.

In the sciences the combination of different types of analysis, textual and visual, contributes to the legibility of the results of the research. Techniques such as data visualization and information graphics have a long history in the natural and social sciences. Recently, researchers in the humanities have got interested in producing visualizations to synthesize facts and trends. The purpose is to create novel observations and analysis of historical and cultural data. This paper presents the use of programming and markup languages to design a custom and open tool for the creation of one particular type of historical data visualization: chronologies.

KEYWORDS: Data visualization, chronology, XML, processing.

Harun Farocki 1944-2014

Tags: | Categories: art, Deutschland

This is another sad week. The German film and video artist Harun Farocki has passed away last Wednesday at the age of 70. The last work I saw of him was Serious Games at Hamburger Bahnhof in Berlin with Nelson Vergara. Farocki’s works in video were radical in form and with a strong socio-critical content. Farocki! we will remember you.

Laboratorium mechanicum (1700)

Tags: , , | Categories: machine

The five vowels of the Christopher Polhem’s mechanical alphabet (1700), the lever, the wedge, the screw, the pulley, and the winch are but one example of the mechanistic order of knowledge during the 18th century. This alphabet is too the seed for the industrial age. A seed constituted of a set of discrete blocks that assembled in various forms generate endless mechanisms and machines either to mimic nature and to create new natures. These discrete elements are drawn from the alphabet and written culture. Ideas are broken down to sentences, words, and ultimately letters. The alphabet is the first component in the mechanisation of thought.
