	Gilles de Roberval - Wikipedia, the free encyclopedia
		Roberval was one of those mathematicians who, just before the invention of the infinitesimal calculus, occupied their attention with problems which are only soluble, or can be most easily solved, by some method involving limits or infinitesimals, and in the solution of which accordingly the calculus is always now employed.
		Another of Roberval’s discoveries was a very general method of drawing tangents, by considering a curve as described by a moving point whose motion is the resultant of several simpler motions.
		As results of Roberval’s labours outside the department of pure mathematics may be noted a work on the system of the universe, in which he supports the Copernican heliocentric system and attributes a mutual attraction to all particles of matter and also the invention of a special kind of balance, the Roberval balance.

	Roberval
		It is the county seat for Lac-Saint-Jean-Ouest (1892) and headquarters for the judicial district of Roberval (1912).
		Named for France's lieutenant-general in Canada in the 16th century, Roberval was founded in 1855 and grew rapidly after 1888 when the Québec-Lac-Saint-Jean railway company (amalgamated into the Canadian National Railway in 1917) decided to make the town its Lac Saint-Jean terminal.
		Since then, Roberval has been the service centre of the area, and since 1955 it has yearly hosted the prestigious swim, the Traversée International du Lac-Saint-Jean.

	History of the Differential from the 17th Century
		At nearly the same time as Roberval was devising his method, Pierre de Fermat used the notion of maxima and the infinitesimal to find the tangent to a curve.
		Roberval applied this method to find the tangents to curves for which he was able to determine the constituent motion vectors at a point.
		Roberval was never able to generalize this method, and therefore exists historically only as a precursor to the method of finding tangents using infinitesimals (Edwards 133-138).

		The Roberval balance achieves non-rotation of the pans by use of a parellogram linkage of levers.
		A Roberval linkage could be made to balance unequal masses, or to balance for a particular ratio of masses, say 1:10.
		The pans of a Roberval balance move in such a way that the radius of the arc of motion of a weight is independent of its position of the weight on the pan.

		Having put off supper until the ROBERVAL got into calmer waters, Delia Parent was attempting to sleep in her cabin when the lake came calling and slammed into the starboard side.

		Darkness, the hull of the ROBERVAL and a sea of spruce separated the lifeboat from Captain Eligh and Delia Parent.
