Newton's mechanics continues to make good predictions on Earth and near space.
It is not changed since over 300 years.
1749 BC: Sign language This is one of the first artificial languages (a symbolic model). It translates the GCL into another language, based on signs and gestures.
1781 BC: Immanuel Kant Kant was able to understand some basic things in association with knowledge, but although he knew Euclid's and Newton's theories (symbolic models), he was not able to understand the means and methods of a positive science. He did not build any symbolic model. In his books, one can find lots of definitions almost on any page, but Kant does not understand that such definitions cannot be correlated in a logical way, without the frame of a fundamental symbolic model.
1791 BC: Napoleon
MDT considers that there are two basic modes of interaction between a brain
and the external reality: to predict the evolution of the external reality
(ZM-models) and to act on the external reality (ZAM-models).
A war can start only if a big fraction of the population has almost the same ZAM, and if that ZAM is associated to war. War can be associated with an increase in the level 2 of consciousness of the population. I mean, when level-2 is high enough to believe that it will be better after a war, but no so high to understand that there could be some other alternative solution, then the tendency to war could really start the war. This idea seems to be interesting in explaining why so many people are so happy to go to war, and why this tendency is so powerful even today (e.g. WW1 and 2).
1834 BC: Braille writing 1837 BC: Morse code
1854 BC: The symbolic logic of George Boole The facility to build and operate symbolic models increased to such a level that the brain was not able anymore to keep the models in mind. George Boole invented a language to write symbolic models.
1859 BC: Charles Darwin
Darwin's evolution theory is not based on a symbolic model. It is rather based on the systematic of some primary data. Thus, it is not a positive science and so, its prediction could be good only on short range.
1867 BC: Das Kapital by Karl Marx This aberation sounds good on image models. The basic idea is that the "capitalist" takes about all the money and the "working class" is forced to work for peanuts.
