What is Complexity?

T-99 0CA water molecule in a container at 990C

T-99 0C

The molecule moves in a disordered way bumping on the walls from time to time.

What Happens if one heats the walls of the container by 2 degrees?

A water molecule in a container at 990C

The molecule moves in a disordered way bumping on the walls from time to time.

T-99 0C T-101 0C

Almost nothing: the molecule will bump on the walls in average a little bit faster.

What Happens if one heats the walls of the container by 2 degrees?

T-99 0C T-101 0C

What happens if one adds 3 more water molecules (at T= 990C) ?

A water molecule in a container at 990C

T-99 0C T-101 0C

Almost nothing! They will also occasionally bump among themselves; Their average speed will be equal to the one of the single molecule before.

T-99 0C

What happens if one adds 3 more water molecules (at T= 990C) ?

T-99 0C T-101 0C

What happens if one increases now the temperature by 20C?

T-99 0C

T-99 0C T-101 0C

Almost nothing, they will just increase a bit their average speed.

What happens if one increases now the temperature by 20C?

T-99 0C T-101 0C

What happens now, if one introduces in the container 1Kg of such molecules and repeats the experiment of heating the walls by 20C?

T-99 0C T-101 0C

T-99 0C T-101 0C

T-99 0C T-101 0CVery Dramatic Effect:

T-99 0C T-101 0C

T-99 0C T-101 0C

Very Dramatic Effect: the spatial and speed distributions become inhomogeneous, and a lot of coordinated motion (bubbles) takes place: The water boils.

T-99 0C T-101 0C

Does a new fundamental law of Nature become active in between the 4 molecules and the 1 Kg of water?

T-99 0C T-101 0C

Yes and No: the actual interaction laws between molecules are not changed.

Does a new fundamental law of Nature become active in between the 4 molecules and the 1 Kg of water?

T-99 0C T-101 0C

Yes and No: the actual interaction laws between molecules are not changed.But the existence of a large number of molecules leads to some new, collective, emergent, complex effects of those laws. This is a law of nature of a new type: More is Different(Anderson 1972)

T-99 0C T-101 0C

Could it be that similar effects govern the emergence of life from chemistry, of meaning from simple signals, of societies from individuals, of health from simple cells?

(Anderson 1972)

Could it be that similar effects govern the emergence

of life from chemistry,

of meaning from simple signals,

of societies from individuals,

of health from simple cells

etc?

Could it be that many complex phenomena unexplained until nowcould be the result of simple interactions among their simple components?

To answer this one needs to transcend the traditional research within a single discipline and use trans-disciplinary methods.

This requires growing a new generation of bi- or multi-lingual scientists.

This requires more than a juxtaposition of expertizes.

Main research frameworks:

-The micro-macro representation

-The triangle team

The interdisciplinary research requires typically (at least) 2 senior researchers from the relevant fields (the one knowing about “water molecules” and the one knowing about “boiling”) and one student. It is typically in the mind of the student that the connection between the laws of the water molecules and the laws of boiling will become one.

The research structure of the project will then be

Prof. in Field 1 PhD Student Prof in Field 2

The conceptual structure will be:

Microscopic Elements Microscopic Interactions Emergent Macroscopic Complex Phenomena

My coworkers and I implemented this scheme in a wide range of domains as seen on the following page.
