Joseph Valentin Boussinesq
Joseph Valentin Boussinesq was a French mathematician and physicist who made significant contributions to the theory of hydrodynamics, vibration, light, and heat.Biography
From 1872 to 1886, he was appointed professor at Faculty of Sciences of Lille, lecturing differential and integral calculus at Institut industriel du Nord. From 1896 to his retirement in 1918, he was professor of mechanics at Faculty of Sciences of Paris.
John Scott Russell experimentally observed solitary waves in 1834 and reported it during the 1844 Meeting of the British Association for the advancement of science. Subsequently, this was developed into the modern physics of solitons. In 1871, Boussinesq published the first mathematical theory to support Russell's experimental observation, and in 1877 introduced the KdV equation. In 1876, Lord Rayleigh published his mathematical theory to support Russell's experimental observation. At the end of his paper, Lord Rayleigh admitted that Boussinesq's theory came before his.
In 1897, he published Théorie de l'écoulement tourbillonnant et tumultueux des liquides, a work that greatly contributed to the study of turbulence and hydrodynamics.
The word "turbulence" was never used by Boussinesq. He used sentences such as "écoulement tourbillonnant et tumultueux". The first mention of the word "turbulence" in French or English scientific fluid mechanics literature can be found in a paper by Lord Kelvin in 1887.Books by Joseph Valentin Boussinesq
