In my research, below point of view has an important state, that is the complement to the traditional view of conflicted historiography of physico-mathematics in 17th-18th century Europe. We have also already known very typical cases of conflicts, for example Newton and Leibniz’s priority race on the discovery of calculus, Barkley and Continental mathematicians Discussion over the existence and utilization of infinitesimal small quantity, etc.

Is there any other way in order to represent a new historiography of 18th century?

Main appropriate material is an example that can express the reception and exchange of knowledge in this era, c’est-a-dire: ballistics problem. There are some possibilities to contribute to my attempt for building new historiography in this domain. And my study does not only concerned history of the exact science but also more general situation of Central Europe till the half of 18th century: military, state, mathematician, transition of new devices etc.

On the theory of ballistics in the middle of 18th Century, we have already so many prior researches including B. Robins and L. Euler. But further past research should be expanded so as to comprehend the total situation in these two centuries and the origin of ballistics revolution. Therefore, I emphasize here the French tradition which had the strongest army in this era and I especially analyze several talented researchers.

At first, François Blondel was an important practical and theoretical engineer situated in the last position of pre-Newtonian age and I treat his work. Secondly, Jacques Cassini who is the son of Giovanni Domenico Cassini, successor of Observatoire de Paris, tried to make a new instrument for measuring ballistic nozzle speed. Last person is a well-known savant, Pierre Varignon who had acquired old and new kinematics and mathematics. Can we find any indications of the ballistic revolution in this pre-phase and make a few modifications on ordinary conflicted historiography?
