It deals with the two main discoveries made by Fourier, namely his Series-Transform (of which we should celebrate the bicentennial), and his pioneer work on Linear programming.
It highlights 3 important items: - the "undiscoverable" article of March, 1808 at the Philomathique. - a Theorie analytique de la chaleur (1822) with an interesting pedigree. - a special issue (1824), "for the Happy Few", of the Analyse des travaux for the year 1823, where the bases for LP are clearly settled.
And also two nice monthly "as issued" July 1826 Philomathique and Ferussac Bulletins. With exclusive views of the Chateau de Beauregard, the place where Fourier used to retreat at summer time, and where we suggest he found the mathematical part of his theory of heat.
