Alan Turing defined in 1936 the now well known "Turing Machine" to define computation. A Turing Machine is actually an abstract mathematical construction, which cannot be fully materialized, since it requires an infinite tape (memory). Nevertheless, people have been discussing their brains out on whether the human mind (whatever that may be) is computable or not. This is because people believe that if whatever our brains or minds do is computable, then (in principle) it could be modelled in a computer, thus reaching the ultimate goal of artificial intelligence: a machine with the same intellectual abilities as a human (whatever that may be). Still, computability as we understand it, i.e. Turing computability, i.e. a function that a Turing machine can perform, is only computability in theory . In practice , there are Turing-computable numbers that are not computable in practice by our computers, since there would not be enough time in the universe to calculate them, or memor...

The term "Artificial Intelligence" (AI) was coined at a conference in Dartmouth College, NH, in the summer of 1956, so this year has seen several celebrations, e.g. in Boston, Monte Verità , Paris... so Brussels couldn't be left behind! The AILab of the VUB organized a one day event at the Royal Flemish Academy for Arts and Sciences, with invited talks by people who have done advancements in AI in Flanders... so it was basically VUB people (i.e. ex-students of Luc Steels ) and a couple from Leuven. You can see the full info here (in Dutch). So, during and after the presentations, I realized how the expectations of AI have changed. In the 50's, people were predicting that we would have robots with humanlike intelligence in a few decades. In the 80's, a new wave of AI began to spread, namely with behaviour-based systems, neural networks, dynamical systems theory, and artificial life. Many of these were also aiming at humanlike intelligence (from the bottom-up), s...

Yesterday, November 20th, 96th anniversary of the Mexican Revolution, Andrés Manuel López Obrador took protest as the legitimate president of Mexico. Since the circles of power have corrupted the national institutions and the media, culminating with the presidential elections fraud last July 2nd, more than a million Mexicans, of which several were representing many others, gathered last September at a National Democratic Convention, and elected López Obrador as the legitimate president (well, he had won already, but since the electoral institutions and tribunals were corrupted, they gave the victory to the puppet Felipe Calderón, who will attempt to take possesion of a spurious presidency on December 1st). The new legitimate government will be defending the rights of the majority of Mexicans, living in poverty and "forgotten" by the people in power (they have not forgotten, they are just being unmercifully exploited). For example, the President proposes to the Congress the bu...

What to expect from Web 3.0 by ZDNet 's Phil Wainewright -- Web 2.0 is just a staging post. Web 3.0 is coming, and it's going to recreate our notion of the application as well as upsetting a few applecarts along the way.

Heylighen, F., P. Cilliers, and C. Gershenson (forthcoming 2007). Complexity and Philosophy In Bogg, J. and R. Geyer (eds.) Complexity, Science and Society . Radcliffe Publishing, Oxford. Abstract: The science of complexity is based on a new way of thinking that stands in sharp contrast to the philosophy underlying Newtonian science, which is based on reductionism, determinism, and objective knowledge. This paper reviews the historical development of this new world view, focusing on its philosophical foundations. Determinism was challenged by quantum mechanics and chaos theory. Systems theory replaced reductionism by a scientifically based holism. Cybernetics and postmodern social science showed that knowledge is intrinsically subjective. These developments are being integrated under the header of "complexity science". Its central paradigm is the multi-agent system. Agents are intrinsically subjective and uncertain about their environment and future, but out of their l...
