What is the meaning of FLOGISTINE or FLOJISTINE ?

Answer 1

Right spelling is phlogistine.

This concept was used to explain the results of a domestic observation that the majority of people made during their life during the Middle Ages: a lit candle, placed in a hermetic container, died out in a few minutes, with any blow.

The explanation at the time was that the combustible matter of the air was then exhausted. And it is this element which one called the phlogistine (of the Greek, phlogistikos, flammable). Fire being, as everyone knows, one of the four fundamental components of our universe with water, the ground and the air. We were at the same time close (there was indeed a combustible matter in the air: oxygen) and very far from a solution applicable to other uses.

While traversing excel it courses " the light on the restricted relativity " of Gaspard Petit and Yannick Solari, one comes from there about to the same impression as in the case from the phlogistine. But today, it is the Ether and the speed limit of the light...

In a case, one does not find trace of this "Ether"; in the other, one notes that the speed of the light can be exceeded (in transparent mediums with high density) or be stopped (in gas cooled close to the absolute zero, according to an experiment carried out in the United States in 2001 and opening the way with the storage of photonic data!)

In short, a theory undoubtedly good to explain a part of our universe, like was to it that of Newton, but which one will still have need to exceed...
