	Poncelet, Jean Victor (1788-1867)
		With Brianchon, he proved Feuerbach's theorem on the nine-point circle in 1820-21, and also suggested the theorem proved by Steiner and now called the Poncelot-Steiner theorem that Euclidean constructions can be done with a straightedge alone.
		As a soldier in Napoleon's army, he was captured and imprisoned in Russia.

		In geometry, the Poncelet-Steiner theorem on ruler-and-compass constructions states that whatever can be constructed by straightedge with compass, can be constructed by straightedge alone, if you are given a single circle and the location of its centre.

	Nine Point Circle Investigation
		It was first proven by French mathematicians Jean-Victor Poncelet and Charles Brianchon in 1821 and further explored by Karl Willhelm Feuerbach who discovered many of its properties.
		In order to understand this exploration, you need to be familiar with the four concurrency points in a triangle and the Euler Line.
		Every triangle has a nine point circle which is connected to both it's inscribed circle, circumscribed circle, and Euler Line.

	History of water turbine technology (from turbine) -- Encyclopædia Britannica
		In 1826 Jean-Victor Poncelet of France proposed the idea of an inward-flowing radial turbine, the direct precursor of the modern water turbine.
		The term also is conventionally used to describe a complete internal-combustion engine consisting of at least a compressor, a combustion chamber, and a turbine.

		1, points D, E, F, G, H, and I.) (At a slightly earlier date, Charles Brianchon and Jean-Victor Poncelet had stated and proven the same theorem.) But soon after Feuerbach, mathematician Olry Terquem himself proved the existence of the circle.
		In 1822 Karl Feuerbach discovered that any triangle's nine point circle is externally tangent to that triangle's three excircles and internally tangent to its incircle.
		Although he is accredited for its discovery, Karl Wilhelm Feuerbach did not even discover, in its entirety, the nine point circle.

	Nine point circle
		At a slightly earlier date, Charles Brianchon and Jean-Victor Poncelet had stated and proven the same theorem.
		It is named so because it passes through nine significant points, with six of them lying on the triangle itself: the midpoints of the three sides, the feet of the altitudess, and the midpoints of the portion of altitude between the vertices and the orthocenter.
		Soon after Feuerbach, mathematician Olry Terquem also proved what Feuerbach did and added the three points that are the midpoints of the altitude between the vertices and the orthocenter.

	The Real Projective Plane
		The real projective plane is a central object in a classical subject known as "projective geometry", which was an outgrowth of the work of the Renaissance artists and some later geometrically-minded philosophers, especially Jean Victor Poncelet, who undertook to axiomatize its geometry.
		The 3 line segments where the squares intersect are not to be regarded as edges of the tetrahemihexahedron.
		It is probably the simplest example of a closed non-orientable surface; removing a disc from the real projective plane may yield another familiar non-orientable surface, the Möbius band.

	Articles - Water wheel
		In the 19th century, Jean-Victor Poncelet worked on improving the efficiency of the undershot design using modern hydraulic physics for the first time.
		Smeaton performed experiments in 1754 that conclusively demonstrated the superiority of the overshot system: Brindley was Smeaton's pupil, and one of his water wheels can be seen at the Brindley Mill in Leek, Staffordshire, England.
		Water wheel technology was developed extensively in England in the 18th century, with notable figures including John Smeaton and James Brindley, following theoretical calculations and practical experiments in France and elsewhere.
