The human being is born with a stock of about 100 billion neurons. At birth, only 10% of these connections, the synapses, are already completed. The remaining 90% will build gradually as environments (family, school, the internet, etc.) enable the decoding of the information collected (chapter 6, no 19).

Information above all is a measure of the human being,
since it is always relative to the observer.

Information is related to the ability of the intelligence of the individual to understand it. To understand is to perceive a significant relationship between various phenomena. Knowledge is thus made fit for purpose. The role of information is to make sense of the chaos that arises from the cacophony that exists in our society.

Knowledge is Power.

Francis Bacon (1561-1626)

Information is a resource like water or food:

• 1st Industrial Revolution
Primary resources: natural resources.

• 2nd Industrial Revolution:
Secondary resources: those in the manufacturing industry.

• 3rd Industrial Revolution
Tertiary resources : services

• 4th Industrial Revolution (forthcoming)
Quaternary resources : knowledge and expertise.

In the knowledge-based society, information is intangible capital that is extremely mobile and transformable, especially because it is scanned to the point where modern man becomes an informivore. See, in this regard, the number of information appliances and their global penetration rate in 2013 (figures from the ITU and Morgan Stanley):

TV 5.5 billions 78% global penetration
Such. mobile 5.2 73%
Smartphones 1.6 22%
Laptop 789 millions 11%
Desktop 743 10%
Tablet 439 6%”

Its various forms

Information appears in different forms: text, data, diagrams, images, tweets, etc. For example, it is still surprising when we see all the visual symbols and logos still in everyday use. Our cognitive heritage probably has more than 50,000 symbols :

The great challenge of the twenty-first century will be to transform billions of pieces structured data into knowledge, because, at present, 80% of the data are not structured. The knowledge-based society will become a society of industrialized information when it becomes both :

  • an economic phenomenon (it is a commodity) ;
  • a technical phenomenon (its shape depends on its support) ;
  • a political phenomenon (it involves power relations) ;
  • a cultural phenomenon (it refers to a symbol determined by a given time space).
An iconic grammar

In the area of ​​communications, we have a visual legacy consisting of thousands of signs, symbols and logos. Their use has multiplied because of the recent arrival of various types of smart devices without keyboards and cameras. One problem is now emerging in the field of new media writings: the use of an iconic grammar (chapter 5, no 3).

This grammar is combined either by the addition or combination of graphic elements giving it new meanings. An example is the sign-record :
