Extractions: Died: 19 Feb 1622 in Eton, Berkshire, England Henry Savile entered Brasenose College Oxford in 1561 and he was elected a Fellow of Merton College Oxford in 1565. He graduated with an B.A. in 1566 and an M.A. in 1570. On 10 October 1570 he began to lecture at Oxford on Ptolemy 's Almagest and we are fortunate in that his lecture notes for this course have survived. We shall now describe the content of these lectures more fully. The lectures are far more than Ptolemy 's text with added explanation. Savile introduced his students to the new ideas of Regiomontanus and Copernicus . He mentions both classical authors of mathematics, giving their biographies, and the leading mathematicians of the day whose works he had clearly studied. In the introduction to the lectures Savile gives his views on why students should study mathematics. The study of mathematics, argues Savile, turns a student into an educated, civilised human being. As an example he quotes the classical story of Aristippus who, on being shipwrecked on Rhodes, realised that the inhabitants were civilised when he saw a mathematical figure drawn in the sand. It is worth noting, however, that twenty years later, when Savile was trying to make sure his subject received proper funding, he argued for mathematics because of its practical uses. 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.

Introduction Do the angles of a triangle add up to 180 degrees or radians? The answer is `sometimes yes, sometimes no'. Is this an important question? Yes, because it throws light on the nature of geometry showing that there are different geometries based on different axioms or `rules of the game'. Is it a meaningful question? Well we need to agree the meaning of the words `angle' and `triangle', and to know the rules of the game, before the question becomes meaningful. In this article we briefly discuss the underlying axioms of spherical geometry and give a simple proof that the sum of the angles of a triangle on the surface of a unit sphere is not equal to

Extractions: In 1991, the MAA Board of Governors established Section Awards for Distinguished College or University Teaching of Mathematics to recognize excellence in mathematics teaching at the post-secondary level. The Rocky Mountain Section Award is named in honor of Burton W. Jones, a lifelong advocate of excellence in teaching and a strong supporter of the members and programs of the MAA. In addition to being honored with a certificate and check, award recipients are invited to deliver the opening address at the following year's spring meeting. Criteria for the DTA award require more than merely effective teaching. Awardees are expected to be outstanding teachers who are widely recognized both within and beyond their own institution for their extraordinary success in teaching. Professor Barbara Bath of the Colorado School of Mines is clearly such a teacher. Barbara's students consider her demanding, yet supportive. She is sincere with praise and constructive with criticism, and students quickly recognize her genuine compassion for them. In the last eight years, she has received teaching awards on seven separate occasions, four of which were awarded by graduating seniors at CSM. She was also instrumental in the award of the 1998 Minority Engineering Program Commitment Award to the CSM Department of Mathematics and Computer Sciences. In recent years, Barbara has played an exceedingly important role in the development of new curriculum at CSM. She has provided leadership in the design of several new courses, including a complete revamping of the calculus sequence. She also serves as a mentor in the Guy T. McBride Jr. Honors Program, a program designed to provide students an opportunity to cross the boundaries of technical expertise and gain sensitivity to the moral and social implications of their profession.

Smith, "Just how much influence the passing of the first Christian millennium had upon the common people it is difficult to say. Historians pay much less attention to the 'terreur de l'an Mil' [terror of the Year 1000] than was formerly the case. It is not probable that many educated persons took literally the biblical remark relating to the period of a thousand years, but it is certain that it was so taken by some. At any rate, the passing of this milestone saw the Christian world aroused to new interests." "Then, too, there were the

Extractions: A27. There are many reasons for this. The main reasons are: The behavior of the people, who call themselves Muslims but do not practice the faith, is largely responsible for a confused and distorted picture of Islam. These people profess this faith but do not live by it, they often do every thing which it does not permit and do nothing which is requires. Many people have such an unquestioning conviction of the innate superiority and rightness of their own way of life that they do not consider it necessary or important to be accurately informed about others' view points and way of life. They simply keep following what their parents and society had taught them. Many people think of any religious system in terms of their own concepts and values, or in terms of the concepts of Western civilization. These do not necessarily fit with or apply to Islam.

Extractions: In the absence of thorough and exhaustive accounts for developments in the various scientific disciplines as well as accounts for the epistemological foundations of these sciences, it only stands to reason that attempts to provide general characterizations of science in Muslim societies and its relation to religion can only be provisional and subject to scrutiny. Even such seemingly straight forward characterizations of the scientific activity in Muslim societies as Islamic or Arabic cannot be taken for granted, and the same applies to the assertion that Islam has either a positive or a negative attitude towards science. I do not mean here to deny the validity of using terms such as "Islamic science", but simply to stress the importance of addressing the question of methodology before venturing such general characterizations. Almost invariably, discussions of the Islamic attitude toward science invoke the works of al-Ghazali (d. 505/111). I will not attempt to summarize Ghazali¹s views on the various sciences; these views have received more scholarly attention than those of any other Muslim scholar who had written on the subject. It is important to note, however, that the debate regarding Ghazali¹s true attitudes and views continues among contemporary scholars, and there seems to be no consensus even over the interpretation of his most obvious work
