Photo GALOIS, Évariste. 

First edition of collected mathematical works of Evariste Galois given by Liouville in this volume of the Journal de Mathématiques pures et appliquées .

A brilliant mathematician, misunderstood in his day and with a tragic fate (he died at the age of 20 in a gallant duel), Galois created the notion of group, and his work has inspired generations of mathematicians.
A brilliant student, he was misunderstood by his contemporaries. Poisson rejected the work he wanted to present to the Paris Academy of Sciences.
In 1832, on the eve of his fatal duel, Galois wrote his mathematical will, which he entrusted to a friend.
It was not until 1846 that Liouville published them in this volume of the Journal des mathématiques, and not until 1870 that Jordan recognized their importance.

"When, yielding to the wish of Evariste's friends, I gave myself up, as it were under the eyes of his brother, to the attentive study of all the printed or manuscript pieces he left behind, I therefore thought I had to propose as my sole aim to seek out, to unravel, to then bring out as best I could, what was new in these productions.

My zeal was soon rewarded, and I was delighted when, after filling in a few small gaps, I recognized the complete accuracy of the method by which Galois proves, in particular, this beautiful theorem: For an irreducible equation of prime degree to be solvable by radicals, it is necessary and sufficient that all the roots be rational functions of any two of them.
This method, truly worthy of the attention of geometers, would alone suffice to secure our compatriot a place among the small number of scientists who have earned the title of inventor." (Liouville p.382).

Interesting set of working documents of a Scienfitic Society from Marseille in the 18th century.
At the beginning of the eighteenth century two projects of a foundation of a Marseille Academy clashed, the first wanted to devote himself solely to Sciences, the second on the model of the French Academy, wanted to focus on Letters. It is the second project supported by the governor of Provence which won the support of Louis XV and the Academy of Belles-Lettres de Marseille was founded in 1726. It was only in a second time, in 1766, that it will open up to Sciences and the Arts.
We imagine the dismay of Marseilles scientists during the interval, and it is probably this frustration which is at the origin of the creation of the Société des Sciences de Marseille of which we present some documents here.
Lot consisting of 6 pieces:
- 3 transcripts of speeches, one of which addresses the question of the rules of the "Academy" which excluded the religious. It offers openness to abbots and monks, those with interest libraries, but seeking a solution that avoids animosities between the different orders.
- Speech by the perpetual secretary summarizing the work of the Academy during the period 1739-1740.
- Work report: Geometry of Mr Gérard, Mechanics of Mr De Pontis.
- Bundle of 10 tickets, "Tasks of the Academicians for 1741": Each academician offers on a small autograph ticket signed the scientific work they undertake to address during the year 1741. We find the names of Ganteaume, De Pontis , Pelissery, Gérard, Saint-Jacques, Roussin.
