Father Occupation: Unknown I find only that Carlo Francesco Ceva was rich and famous. I accept the information: wealthy. 3. Nationality Birth: Italian Career: Italian Death: Italian 4. Education Schooling: Pisa He received his first education in a Jesuit college in Milano. He studied then in Pisa where he was a student of D. Rossetti and A. Marchetti, both students of Borelli. There is no mention of a degree. 5. Religion Affiliation: Catholic 6. Scientific Disciplines Primary: Mathematics, Hydraulics Ceva's most important mathematical work was De lineis rectis (Milan, 1678). In this work he used the properties of the center of gravity of a system of points to obtain the relations of the segments. He also published Opuscula mathematica (Milan, 1682), Geometria motus (Bologna, 1692), De re numeraria (Mantua, 1711), and other works. Much of his mathematical work had a practical bente.g., hydraulics. This became more pronounced as the years passed. His final work, and his most important one, was Opus hydrostaticum, 1728.

He taught at Pisa before being appointed Professor of mathematics at the University of Mantua in 1686, a post he held for the rest of his life. When appointed in 1686 Giovanni Ceva served the Gonzagas rulers. However in 1708 Austria annexed the duchy and began to construct heavy fortifications. Giovanni Ceva quickly moved to support the new Austrian regime. For most of his life Giovanni Ceva worked on geometry. He discovered one of the most important results on the synthetic geometry of the triangle between Greek times and the 19th Century. The theorem states that lines from the vertices of a triangle to the opposite sides are concurrent precisely when the product of the ratio the sides are divided is 1. He published this in De lineis rectis Ceva also rediscovered and published Menelaus 's theorem. He also studied applications of mechanics and statics to geometric systems. Although he wrongly concluded that the periods of oscillation of two pendulums was in the same ratio as their lengths, he later corrected the error.

It's a regrettable fact because not only it unifies several other more fortunate statements but its proof is actually as simple as that of the less general theorems. Additionally, the general approach affords, as is often the case, rich grounds for further meaningful explorations. Ceva's Theorem In a triangle ABC, three lines AD, BE and CF intersect at a single point K if and only if (The lines that meet at a point are said to be concurrent Proof 1 Extend the lines BE and CF beyond the triangle until they meet GH, the line through A parallel to BC. There are several pairs of similar triangles: AHF and BCF, AEG and BCE, AGK and BDK, CDK and AHK. From these and in that order we derive the following proportions: AF/FB=AH/BC (*) CE/EA=BC/AG (*) AG/BD=AK/DK AH/DC=AK/DK from the last two we conclude that AG/BD = AH/DC and, hence, BD/DC = AG/AH (*).

13. Saccheri, Giovanni Girolamo Under ceva's influence he published his first book, Quaesita geometrica (1693). Throughceva he became a correspondent and friend of giovanni ceva and Viviani. http://es.rice.edu/ES/humsoc/Galileo/Catalog/Files/saccheri.html

Dates Born: San Remo, Genoa, 5 Sept. 1667 Died: Milano, 25 Oct. 1733 Dateinfo: Dates Certain Lifespan: 2. Father Occupation: Lawyer Giovanni Felice Saccheri was a notary. No information on financial status. 3. Nationality Birth: Italian Career: Italian Death: Italian 4. Education Schooling: Religous Order, D.D. He entered the Jesuit novitiate in Genoa in 1685. Sent to Milan in 1690, he studied philosophy and theology at the Jesuit College of Brera. Here he was influenced to study mathematics by Tommaso Ceva. As an ordained Jesuit professed of the fourth vow, he would have had a doctorate in theology. 5. Religion Affiliation: Catholic He entered the Jesuit novitiate in 1685, and was ordained a priest in 1694 at Como. 6. Scientific Disciplines Primary: Mathematics Subordinate: Mechanics His two most important books, the Logica demonstrativa (1697), an explanation of logic more geometrico, and the Euclides ab omni naevo vindicatus (1733), were virtually forgotten until they were rescued from oblivionthe Euclides by E. Beltrami in 1889 and the Logica by G. Vailati in 1903. Much of his logical and mathematical reasoning has become part of mathematical logic and non-Euclidean geometry. In 1708 he also published Neo-statica, a work in the tradition of peripatetic statics.

An interactive column using Java applets by Alex Bogomolny A Matter of Appreciation October 1999 I have a recollection. Years ago, a childhood friend of mine, Boris, shared with me with excitement an unusual experience he had on a visit to the Tretj'yakov Art Gallery in Moscow. He was accompanied by a professional painter, a good acquaintance of his older sister. While Boris was making a round in one of the halls, he observed that the painter remained all that time on the same spot studying a certain picture. Curious, my friend asked the painter what was it about the picture that kept him interested in it for so long. According to Boris, the painter did not reply directly, but, instead, stepped over to the picture and covered a spot on the picture with a palm of his hand. "Have a look at the picture and think of what you see," he requested. After a while, he uncovered the spot, stepped back and asked Boris to have another look. Well, almost 4 decades later, with the names of the painter and the picture long forgotten, I still vividly remember Boris' excitement when he told me of how entirely different, deeper and more beautiful, the picture appeared to him then.
