Francesco Siacci

Francesco Siacci ( born April 20, 1839 in Rome, † May 31, 1907 in Naples) was an Italian mathematician, ballistics and officer.

Siacci studied in Rome and went to the final in 1860 to Turin, where he became an officer and professor of mechanics at the military academy. Even in campaigns against Austria and Prussia in 1866, he participated briefly, but was sent back quickly to the Academy. He was born in 1872 professor of ballistics (which he remained until 1892, most recently as a major general ), while from 1875 Professor of Mechanics at the University of Turin. After two terms as an MP, he was appointed Senator in Rome in 1892 and had to put yourself to the University of Naples. In Turin he held an honorary professorship, his successor in the doctrine was there Vito Volterra.

Siacci was in the 19th century known for his textbook on ballistics, which was from 1870 to 1884 and appeared in a second edition in 1888 and 1891 translated into French. He is known for various methods in the external ballistics even today. In addition, he worked on theoretical mechanics ( rigid body motion, canonical transformations, contact transformations, inverse problems ) and mathematical investigations, including the theory of conic sections, the Riccati differential equation, determinants, binary quadratic forms.

Since 1872 he was a corresponding member of the Accademia dei Lincei, 1890, he moved up to a full member. He was also a member of the Accademia delle Scienze in Turin and the Accademia dei Quaranta, the national science academy, and the academy in Naples and Bologna, and the Lombard Academy of Science and Literature.
