||1622: Henry Savile dies ... scholar and mathematician, Warden of Merton College, Oxford, and Provost of Eton. He endowed the Savilian chairs of Astronomy and of Geometry at Oxford University, and was one of the scholars who translated the New Testament from Greek into English. It is interesting to read Savile's comments in these lectures on why he felt that mathematics at that time was not flourishing. Students did not understand the importance of the subject, Savile wrote, there were no teachers to explain the difficult points, the texts written by the leading mathematicians of the day were not studied, and no overall approach to the teaching of mathematics had been formulated. Of course, as we shall see below, fifty years later Savile tried to rectify these shortcomings by setting up two chairs at the University of Oxford. *SAU https://pballew.blogspot.com/2019/02/on-this-day-in-math-february-19.html Pic. | |||
