About Knowledge

What kind of knowledge can be extracted from something essentially new, which is
not relevant to anything known at the moment? Simulating such cognition, we are
trying to simulate the formation of substantially new knowledge in our brain. The
only background knowledge, which we assume in our consideration, is the knowledge
that a text has a sequential structure.

Μικης Θεοδωράκης Μάνος Ελευθερίου Μαρία Φαραντούρη

Ποιος τη ζωή μου, ποιος την κυνηγά
να την ξεμοναχιάσει μες στη νύχτα;
ουρλιάζουν και σφυρίζουν φορτηγά
σαν ψάρι μ’ έχουν πιάσει μες στα δίχτυα

Για κάποιον μες στον κόσμο είν’ αργά
ποιος τη ζωή μου, ποιος την κυνηγά;

Ποιος τη ζωή μου, ποιος παραφυλά
στου κόσμου τα στενά ποιος σημαδεύει;
πού πήγε αυτός που ξέρει να μιλά
που ξέρει πιο πολύ και να πιστεύει;

Pedagogy has not yet found its Pasteur-Petter Johansson -Peter Gardenfors

Pedagogy has not yet found its Pasteur. Most instructional practices are motivated by a combination of folk psychology and a reference to tradition that leads to inconsistencies and potentially harmful recommendations. The reason folk psychology still functions as a foundation is that the sciences of learning are not as mature as could be hoped. What one finds is not one unified theory of learning but a multitude of theories on different levels of explanation—from learning in neurons to learning in groups of individuals.
The theories are often fragmented and far from complete, and they cover scattered application areas. In most cases, it is difficult to see how the theories can be made to work together for more general explanations and 
recommendations. As a matter of fact, different theories sometimes result in conflicting recommendations. There are a lot of conflicts among researchers in the fields of learning, and they seem to have widely diverging visions of what learning really is.

Scientific Models For Education

Effective implementation of the Scientific Method requires good tools as well as insight.
The precision of empirical questions and their answers depends on the available scientific
tools. Therefore, progress in science depends on the invention of powerful tools for
empirical and theoretical investigations.
· Scientific instruments extend the range and acuity of human perception
enormously, making it possible to discover or verify patterns of great subtlety.
· Mathematics (the Science of Patterns) has been created, in large part, to provide
precise conceptual tools and methods for constructing and analyzing refined
models of physical systems and processes.

Computers in Education - P.Sloot CERN School on Computing, Sopron, Hongary August 1994

Sloot,P.(1994). Lecture on Parallel Scientific Computing and Simulations. CERN school on computing, Sopron, Hongary August 1994



The use of computers in physics is becoming increasingly important. There is hardly any
modern experiment thinkable where computers do not play an essential role one way or another. If we take a liberal approach to the concept of experimenting then we can make a fundamental
distinction in the applicability of computers in physics. On the one hand computers are used in
experimental set-ups such as a measuring/controlling/data analyses device, inevitable to the
accurate measurement and data handling. On the other side we have the field where the computer is used to perform some simulation of a physical phenomenon. This is essentially the realm of
computational physics. One of the crucial components of that research field is the correct
abstraction of a physical phenomenon to a conceptual model and the translation into a
computational model that can be validated. This leads us to the notion of a computer experiment
where the model and the computer take the place of the 'classical' experimental set-up and where
simulation replaces the experiment as such.
