1) THE LONELINESS OF THE MATHEMATICIAN
This loneliness is manifest in several respects:
- in education,
most children begin to hate math when they are 11, 12, or 13. At
this ages. children have to face the big changes related to the first
use of the word 'theorem' and the move from natural language to symbolic
language (letters such as a, b, c, x, y, z and some artificial signs).
- historically,
math appeared under the influence of Old Greeks traditions, as a
daughter of myths and as a sister of literature; both inherit from
myths the symbolic function and the replacement of the real world by a
fictional universe. So, with Plato, Kepler, Kant and Goethe math
belongs to humanities, while the declared history places math together
with the so-called natural sciences and exact sciences. This falsification
makes difficult for the common people to understand the psychology
of mathematical creativity.
- Mathematics is generally considered as
a useful tool and sometimes as an adequate language, but its cultural
weight and its spiritual dimension remain hidden for most people.
This is one more source of the loneliness of the mathematician.
- Most
problems addressed to mathematicians need a transformation in order
to become mathematically meaningful. This fact gives to people working
in engineering fields, in economics, medical sciences, linguistics
etc, a feeling of frustration and skepticism in respect to mathematician's
job; this is one more source of isolation of the mathematician.
- Most
intellectuals recall nothing meaningful from their school mathematics;
the cultural weight of mathematics becomes in this way problematic.
- Mathematics
cannot be defined in a few words, it is alone by its cognitive status.
2) TO PROVE OR NOT TO PROVE, THAT IS THE QUESTION!
The Hamletian dilemma concerning the history of the great invention made
by Old Greeks and called 'mathematical proof' is followed step by step,
until its contemporary stage, where the feeling of certainty traditionally
associated with math had to leave the scene and to accept to be replaced
with the more human feeling of doubt.
3) SCIENCE TODAY VERTSUS SCIENCE YESTERDAY
Contemporary education does not point out sufficiently the fundamental
differences between the science of the XX-th century and the Galileo-Newtonian
science. This fact generates much confusion also in the understanding of
relations between science and art. We propose a list of basic differences
between the two sciences. We also point out some basic similarities and
basic differences between science and art, in a contemporary perspective.
The relations between science and engineering follow as a corollary.
4) WE ARE SURROUNDED BY HIDDEN CONFLICTS
Besides the open conflicts, directly visible, there are also conflicts
having the face of agreement and compatibility; only a careful analysis
reveals them. Examples are given from math, logic, physics, computer science,
biology, psychology, sociology, economics, philosophy, literature and art.
5) INFORMATION: WHAT DOES IT MEAN?
"Information" emerged in the second half of the XIX-th century,
from two basic sources: thermodynamics and Darwinian biology. While the
first source lead to the quantitative aspects of information, the second
one remained consistent with the purely qualitative aspect suggested by
the Latin etymology of the word 'information'; in this order of ideas,
information is related to 'form'. We follow the evolution of these two
lines of the history of information in the XX-th century and make the point
of today several tens of meanings of the word 'information'. But the desire
to bridge the respective lines of development is still a failure.
6) MATHEMATICAL MISTAKES AS A SOURCE OF CREATIVITY
Mistakes are generally considered as sins, as negative things. School
education and school examinations are based on this idea and children learn
from the beginning that mistakes are one of the worst possible things that
may happen to them. Against this philosophy, we argue that there are mistakes
that should be interpreted as symptoms of creativity. The way to creativity
is almost always through mistakes and failures. Most great discoveries
and inventions were associated with some mistakes and most great mathematicians
are famous not only by their successes but also by their mistakes and failures
(one exception: Gauss). Mistakes and failures are the prize we have to
pay in order to give a chance to personal thinking and to creativity. A
lot of examples, from the elementary to the higher levels, are given to
illustrate this claims.
7) THE BIOLOGICAL CELL IN SPECTACLE
A lot of directions of research, ignoring each other, each of them having
its specific jargon, its journals, its meetings, have however a common
denominator: each of them begins by claiming that its aim is to understand
the functioning of the biological cell. Ten such directions are pointed
out.
8) TWO NEIGHBORS IGNORING EACH OTHER: INFINITE WORDS AND FORMAL LANGUAGES
To each infinite word over a finite alphabet we can associate various
formal languages and conversely, to each formal language we can associate
some infinite words. Despite this situation, these two fields developed
to a large extent by ignoring each other. We try to bridge this gap and
we sketch some questions and answers in this respect.
