Nasreddin Tusi

             Nasraddin Tusi’s ethic and social-political views are reflected in his “Akhlagi-Nasiri” work, which had been written on behalf of Nasiraddin Mohtasham in 1235. In this work general philosophical issues are also emphasized. The different aspects of characters, their useful and defective sides, the qualities improving a human and advantages leading to favor and happiness are analyzed in this work In his management theology Nasraddin Tusi explains the problems of self, family and state management and thinks that “the control on the people according to the justice and wisdom laws” is very important. Nasreddin Tusi took the humanist position in his works about the religion and considered the care of people’s welfare very important. He is also an author of the treaties about poetry theology and music and philosophic poems. Nasraddin Tusi’s outlook, philosophy, advanced ethic, socio-political as well as theological ideas gets interest not only from the historical point of view but also plays an important role.

       Nasraddin Tusi did many things in the subjects of mathematics, astrology and physics. In his “Zij Elkhani” the main elements of the geocentric orbit of the planets were given and their daily average motion was determined more precisely than the observations of that time and even XVII century astrology. With Nasraddin Tusi’s leadership the rate of the annual precession of the terrestrial axis (51”4) was found (the present rate is 51”2). In “Zij Elkhani” there are a lot of mathematic, astrologic and geographical tables. The most important ones are the three-numbered trigonometric tables of sinus and tangents in the 60 numbered system and the geographic coordinates of 256 cities that were famous in the XII century. C. Columbus’s teacher P. Toscanelli used this table. The table was published in London (1652) and in Oxford (1711) in Arabic and Latin languages. Azerbaijani scientist Kerimaddin Salmasi came to Maragha observatory in 1266 and made a geographic globe 2 centuries ago German scientist Martin Bohaym (1459-1507). Nasraddin Tusi’s “Tahriri-oglidis” (“Evklid’s comments”) gave a push to the develpmnet of geometry. This work was published in Roma in Arabic (1594) and Latin languages (XVII century) and positively affected the work of French mathematician A.Lejandrine, English mathematician J.Wallise and Italian scientist J.Sakkeri. In this work and in “The principles of geometry” Nasraddin Tusi explained his theory on Evklid’s 5th postulate and found the relations between the sums of internal angles of the triangular. Nasraddin Tusi developed the theory of correlation in Archimedes’s works “Ball and cylinder” and “Squarization of the circle”. A number conception of Nasraddin Tusi coincides with the modern notion and he passed ahead European mathematicians 400 years ago.

Nasraddin Tusi also paid attention to the theological issues in his philosophical treaties “Solutions of the problems” (“Hall al-mushkilat”), which had been devoted to the comments of “Signs and remarks” book by Ibn Sina, “World isolation” (“Tajrid al-kelam”) and “The essence of quotation” (“Esas al-iqtibas”). At the Manuscripts Institute of the National Scientific Academy of Azerbaijan there are the copies of the manuscripts of “Solutions of the problems” belonging to the XIII and XVII centuries. Nasraddin Tusi is a famous follower of Ibn Sina’s and Bahmanyar’s schools and developed the East peripatetic. Nasraddin Tusi first divided the creature into cause and result, showed that there was no time difference between them and considered that a possible creature as well as material world was eternal and everlasting.
