It was also Cramer who informed Le Sage about Fatio's theory in 1749.
However, the conceptual framework of this effect is very different from the theory of Fatio and Le Sage.
He often referred to Le Sage's theory in his lectures on physics at the University of Göttingen.
He went on to say that the emission of light is the exact converse of the absorption of Le Sage's particles.
Plasma The Le Sage mechanism also has been identified as a significant factor in the behavior of dusty plasma.
He went on by saying: Kelvin himself,however, was not optimistic that Le Sage's theory could ultimately give a satisfactory account of phenomena.
The re-examination of Le Sage's theory in the 19th century identified several closely interconnected problems with the theory.
Alain-René Lesage(French pronunciation:; 6 May 1668- 17 November 1747; older spelling Le Sage) was a French novelist and playwright.
Here Darwin replaced Le Sage's cage-like units of ordinary matter with microscopic hard spheres of uniform size.
Lorentz After these attempts, other authors in the early 20th century substituted electromagnetic radiation for Le Sage's particles.
Le Sage discussed the theory in great detail and he proposed quantitative estimates for some of the theory's parameters.
Roger Joseph Boscovich pointed out, that Le Sage's theory is the first one, which actually can explain gravity by mechanical means.
Of course, neither the CMBR nor neutrinos propagate at superluminal speeds, which is another necessary attribute of Le Sage's particles.
According to Le Sage, after creating and sending his essay he was informed on the theories of Fatio, Cramer and Redeker.
Some fragments of these manuscripts andcopies of the poem were later acquired by Le Sage who failed to find a publisher for Fatio's papers.
So Kelvin re-iterated an idea that Fatio had originally proposed in the 1690s for attempting to deal with the thermodynamic problem inherent in Le Sage's theory.
His basic assumptions were very similar to those of Le Sage and Preston, but he gave a more detailed application of the kinetic theory.
But this issue later was discussed in a more detailed way by Poincaré, who showed that the thermodynamic problem within Le Sage models remained unresolved.
Subsequently, Peter Guthrie Tait called the Le Sage theory the only plausible explanation of gravitation which has been propounded at that time.
However, Bernoulli himself was the opinion that his own kinetic theory of gases was only a speculation, andlikewise he regarded Le Sage's theory as highly speculative.
In 1888 Paul du Bois-Reymond argued against Le Sage's model, partly because the predicted force of gravity in Le Sage's theory is not strictly proportional to mass.
The recognition of these problems,in conjunction with a general shift away from mechanical based theories, resulted in a progressive loss of interest in Le Sage's theory.
Lichtenberg, Kant, andSchelling Georg Christoph Lichtenberg's knowledge of Le Sage's theory was based on"Lucrece Newtonien" and a summary by Prévost.
Kelvin and Tait Le Sage's own theory became a subject of re-newed interest in the latter part of the 19th century following a paper published by Kelvin in 1873.
He concluded that only in the instance ofperfectly inelastic collisions(zero reflection) would Newton's law stand up, thus reinforcing the thermodynamic problem of Le Sage's theory.
This makes Le Sage theory fundamentally incompatible with the modern science of mechanics based on special relativity, according to which no particle(or wave) can exceed the speed of light.
Lichtenberg originally believed(like Descartes)that every explanation of natural phenomena must be based on rectilinear motion and impulsion, and Le Sage's theory fulfilled these conditions.
Unless the Le Sage particles are moving at speeds much greater than the speed of light, as Le Sage and Kelvin supposed, there is a time delay in the interactions between bodies the transit time.
The theory proposed a mechanical explanation for Newton's gravitational force in terms of streams of tiny unseen particles(which Le Sage called ultra-mundane corpuscles) impacting all material objects from all directions.
Laplace Partly in consideration of Le Sage's theory, Pierre-Simon Laplace undertook to determine the necessary speed of gravity in order to be consistent with astronomical observations.
