Review of "Science"

Science is a multi faced notion

This review of a Knol article has evaporated together with Knol itself
but is adapted here below as a self-standing article.

We can see that the world is complex, fast moving, with many soft and
uncertain aspects.

Thus, what research, facts, knowledge and interpretations can we
call "scientific"
Without being too restrictive and therefore missing many aspects ?

What is science?

Science is about knowledge knowledge, of course,
But what kind of knowledge?

Just bodies of knowledge that became widely accepted?
Is it enough to consider current paradigms as definitive certainties ?

Science is also about formal interpretations (theories, laws)
of facts
that gives hints (if not full certainty) about what can happen
in similar cases.And to find those facts and bring interpretations
requires research.

=> OK then,
* what kind of formalized knowledge,
* what serious research of facts
* and what consistent interpretations
can be called scientific?
Here come the person human factor.
To what extent personal experiences (and creations), clearly
formalized (assumptions),
bring enough evidences to be called research,
if not science?

It might be less feasible in some areas in which there are :
* more complexity and change than in others,
* more "soft" (= human) aspects.

Or on the contrary more feasible?

Can a perfect knowledge of the elements of a system, and even
of how they interact, be enough to explain a dynamic "emergent"
system ?
Or are not only the components but also the properties of the
system itself
what explains the evolutions it underwent, such as
self-organization and emergence?

More generally, fog uncertainty is one of the famous (and
...certain ?) "laws" of the universe.
Here therefore hot debates surge, in which we have to choose between
an open and
a reductive position

I will give my two cents by saying that we need an open mind and should
cover the whole range of scientific areas, and more practically that two
types of formalized knowledge have to be accepted as science.

The two types of sciences

Hard to make categories within something as multifaced as science
But as a rough approach we might say that what we define as formalized
, coming from consistent research and interpretation, covers
two main "families:

* HARD sciences, applied to the chemical physical universe.

This is an area of stable and predictive models (at least in the form
probabilities), in which the theorized phenomena repeat identically
under precise conditions. Many of those models use mathematical or at
least logical laws.

In this area Aristotle's logic is supposed to apply.
With (binary and debatable) postulates such as:

"one cause, one effect",
"things can only be true or false"...

But even here, hard logic can be restrictive (see fuzzy logic), as things are
fully objective, clear-cut, stable and predictive. For example:
  • Many theories and even common paradigms
 are still theories, meaning not fully proven.
  • About the facts themselves, they are still grey zones
between white and black, between their existence and their
  • The "laws" work only under some strict conditions, 
and even so, various interferences can thwart them.
  • Bifurcations and chaos are all over the place (hello, butterfly!).
  • Singularities stay unexplained.
  • Uncertainty stays present (hello Schrödinger's cat!).
  • And we are still far from finding the famous "string theory"
that would cover all universal phenomena.

* SOFT sciences, related to human beings and human 
group societies

Here it is harder to find permanent laws / stable equilibrium
models / objective probabilities.

* Although there is more uncertainty, and although Aristotle' binary logic
   is in check (with many more grey / ambiguous zones of half-truths /
falsehoods, if only because human / social nature is even more
   complex and evoluting than the physical nature ,

* Observation stays feasible and useful, subjective approaches
   are helpful and they cannot be demonized as "unscientific
   All the more if their applications show their unefulness

   What would be unscientific would be to condemn research and the quest
(flexible) explanation theories on those subjects under the pretense
   that they
are ambiguous and/or evolving.

The full extent of science
...and its vulnerability

I propose that the broadest definition of science, as given above, get used
in educational articles.
But we must recognize that all knowledge and sciences, even the hardest
have weaknesses, as new paradigms can put to test some old ones.
in general has to be learned but often also delearned.

As for the relation between science and innovation, a specific article
them, as applied science is a powerful source of innovative initiatives,
but not
the only one.
