The movie "Beautiful Mind" directed by Ron Howard is about a genius global mathematician, John Nash's life. In the movie, the main actor, John Nash is a schizophrenic patient who suffers from hallucination and delusion, and his illusion appears as three distinct characters. Each researcher has had a different opinion on the interpretation of these three characters, but many parts of their opinions are losing consistency. Especially the girl is assumed to be a character from the main actor's hallucination because she is ageless or there is no interpretation of the girl. Although the director Ron Howard did not adopt Aldous Huxley's theory "the more you know the more you see" for the movie, he analyzed the characters in the way of his own with thinking that he can analyze them in accordance with the knowledge level of audience. The imaginary characters come out from John Nash's head and who he wants to be. They are the basic human needs, earthly desire, sexual desire and the desire for honor. John Nash minutely reflects these three kinds of desires in an imaginary world through the three characters. This thesis is to newly suggest the symbolic meaning of the imaginary characters in the movie by clearly analyzing the meaning of the controversial three characters.

With the 500th anniversary commemoration of Gerard Mercator's birth in 2012 now passed, there is the possibility that his name will fade back into obscurity. This would be both unfair and pitiful, because Gerard Mercator's name should be highly regarded as one of the principal contributors to navigational science and the promotion of marine safety. An accomplished cartographer, in 1569 Mercator published a remarkable 18-folio world map, depicting the then-known world in a new format with straight rhumb lines. While this distorted the size of land masses, particularly in higher latitudes, this new projection made navigation much easier for now all sailors had to do was to draw a straight line between two points to plot their course. Mercator clearly had this navigational benefit in mind, though his contemporaries did not immediately recognize its value. It wasn't until after Mercator's death, when Edward Wright (1599) and Henry Bond (1645) used and explained the new projection and demonstrated the use of straight rhumb lines in navigation that the Mercator projection became the standard for sea charts. Today, 450 years later of his death, electronic charts still rely on the projection Mercator invented and developed, confirming his position as a giant in the history of navigation. This paper introduces his life and work, detailing the importance of the 1569 world map and its contribution to navigational science and safety.

Today's healthcare, intelligent robots, smart home systems, and car sharing are already innovating with cutting-edge information and communication technologies such as Artificial Intelligence (AI), the Internet of Things, the Internet of Intelligent Things, and Big data. It is deeply affecting our lives. In the factory, robots have been working for humans more than several decades (FA, OA), AI doctors are also working in hospitals (Dr. Watson), AI speakers (Giga Genie) and AI assistants (Siri, Bixby, Google Assistant) are working to improve Natural Language Process. Now, in order to understand AI, knowledge of mathematics becomes essential, not a choice. Thus, mathematicians have been given a role in explaining such mathematics that make these things possible behind AI. Therefore, the authors wrote a textbook 'Basic Mathematics for Artificial Intelligence' by arranging the mathematics concepts and tools needed to understand AI and machine learning in one or two semesters, and organized lectures for undergraduate and graduate students of various majors to explore careers in artificial intelligence. In this paper, we share our experience of conducting this class with the full contents in http://matrix.skku.ac.kr/math4ai/.

From 1876 to 1883, British mathematician James Joseph Sylvester worked as the founding head of Mathematics Department at the Johns Hopkins University which has been known as America's first school of mathematical research. Sylvester established the American Journal of Mathematics, the first sustained mathematics research journal in the United States. It is natural that we think this is the most exciting and important period in American mathematics. But we found out that the International Congress of Mathematicians held at the World's Columbian Exposition in Chicago, August 21-26, 1893 was the real turning point in American's dedication to mathematical research. The University of Chicago was founded in 1890 by the American Baptist Education Society and John D. Rockefeller. The founding head of mathematics department Eliakim Hastings Moore was the one who produced many excellent American mathematics Ph.D's in early stage. Many of Moore's students contributed to build up real American mathematics research power in early 20 century The University also has a well-deserved reputation as the "teacher of teachers". Beginning with Sylvester, we analyze what E.H. Moore had done as a teacher and a head of the new department that produced many mathematical talents such as L.E. Dickson(1896), H. Slaught(1898), O. Veblen(1903), R.L. Moore(1905), G.D. Birkhoff(1907), T.H. Hilderbrants(1910), E.W. Chittenden(1912) who made the history of American mathematics. In this article, we study how Moore's vision, new system and new way of teaching influenced American mathematical society at early stage of the top class mathematical research. and the meaning that early University of Chicago case gave.

In the development of linear perspective, Brook Taylor's theory has achieved a special position. With his method described in Linear Perspective(1715) and New Principles of Linear Perspective(1719), the subject of linear perspective became a generalized and abstract theory rather than a practical method for painters. He is known to be the first who used the term 'vanishing point'. Although a similar concept has been used form the early stage of Renaissance linear perspective, he developed a new method of British perspective technique of measure points based on the concept of 'vanishing points'. In the 15th and 16th century linear perspective, pictorial space is considered as independent space detached from the outer world. Albertian method of linear perspective is to construct a pavement on the picture in accordance with the centric point where the centric ray of the visual pyramid strikes the picture plane. Comparison to this traditional method, Taylor established the concent of a vanishing point (and a vanishing line), namely, the point (and the line) where a line (and a plane) through the eye point parallel to the considered line (and the plane) meets the picture plane. In the traditional situation like in Albertian method, the picture plane was assumed to be vertical and the center of the picture usually corresponded with the vanishing point. On the other hand, Taylor emphasized the role of vanishing points, and as a result, his method entered the domain of projective geometry rather than Euclidean geometry. For Taylor's theory was highly abstract and difficult to apply for the practitioners, there appeared many perspective treatises based on his theory in England since 1740s. Joshua Kirby's Dr. Brook Taylor's Method of Perspective Made Easy, Both in Theory and Practice(1754) was one of the most popular treatises among these posterior writings. As a well-known painter of the 18th century English society and perspective professor of the St. Martin's Lane Academy, Kirby tried to bridge the gap between the practice of the artists and the mathematical theory of Taylor. Trying to ease the common readers into Taylor's method, Kirby somehow abbreviated and even omitted several crucial parts of Taylor's ideas, especially concerning to the inverse problems of perspective projection. Taylor's theory and Kirby's handbook reveal us that the development of linear perspective in European society entered a transitional phase in the 18th century. In the European tradition, linear perspective means a representational system to indicated the three-dimensional nature of space and the image of objects on the two-dimensional surface, using the central projection method. However, Taylor and following scholars converted linear perspective as a complete mathematical and abstract theory. Such a development was also due to concern and interest of contemporary artists toward new visions of infinite space and kaleidoscopic phenomena of visual perception.

호주 정부는 1988년이 유럽인의 호주 이민 200주년이 되는 것을 기념하여 대대적인 행사를 추진하고 있으며 이 행사의 일환으로 1988년 7월 9일 부터 21일 까지 "제29회 국제수학경시대회"를 개최할 예정이다. 이 대회의 주최측에서는 우리나라에도 중ㆍ고등학생의 참가를 요청하였다. 필자들은 이 대회에 우리나라 대표를 파견할 경우를 대비하여 그 동안 IMO에 관한 여러가지의 정보를 조사한 바 대회 참가 여부에 대하여 다음과 같은 결론을 얻었다. 1. 참가의 필요성 (1) 중ㆍ고등 학생들에게 수학에 관한 관심을 높히고, 나아가서는 모든 국민에게 과학적인 사고의 향상을 기대한다. (2) 궁극적으로 수학을 위시한 기초 과학, 응용 과학에 대한 전반적인 관심도가 높아져서 수학자 및 과학자의 저변 확대를 기대할 수 있고, 특히 수리적인 사고력이 뛰어난 사람을 조기에 찾아내어 2000년대의 과학 선진국 건설에 중추적인 역할을 맡을 인력자원을 확보할 수 있다. (3) 현재 중ㆍ고등학교 수학 교육이 계산 위주, 암기 위주로 되어 있고, 학력 고사를 위시하여 많은 시험이 객관적으로 사고력 배양이 고려되지 않고 있다. IMO 참가자를 선발하기 위하여 거국적인 경시 대회를 개최한다면 자연히 이를 대비한 주관식 문제를 접할 기회를 가지게 되고, 따라서 수학 교육의 목적중의 하나인 사고력 배양을 기대할 수 있다. (4) 우리 국민의 조직적인 사고력과 과학적인 두뇌를 세계적으로 자랑할 수 있는 좋은 기회이다. (5) 자라나는 새싹들에게 국제 대회의 기회를 주므로써 장차 우리나라의 수학 수준을 국제적으로 높힐 수 있는 기틀을 마련한다. 2. 우리나라 학생이 IMO에 참가하여 우수한 성적을 거둘수 있는지 여부 (1) 절대적으로 있다. 참가하는 첫 해부터 상위권에 들어갈 것이다. 우리의 중ㆍ고등학교 수학 수준이 세계 평균보다 약간 높다. 그리고 몇 년의 경륜을 쌓는다면 세계 1, 2위에 도전 할 수 있다. 이것은 올림픽이나 아시아 게임에 기울이는 비용의 몇 만분의 일을 가지고, 그 보다 훨씬 높은 수준의 국력을 과시할 수 있는 기회이다. (2)매년 그 성적이 올라가리라 생각한다. 예로서 우리와 비교하여 형편없는 국력을 가진 몽고가 8년간 꼴찌를 하다 1894년 대회에서 참가국 33개국 중에서 10위를 차지하였다. 미국은 참가 첫 해부터 2위를 하였고, 11년 동안 1위 2번, 2위 4번을 하였으며, 매번 5위 이내에 머물렀다. (3) 월남은 그 나라의 사정때문인지 자주 참가하지 못하였다. 그러나 참가할 때마다 항상 상위권에 속하였다. 이것은 월남 국민들의 수학에 관한 관심도를 나타낸다고 본다. 우리 국민도 월남 국민에 못지 않으리라 생각한다. 3. 한국수학교육학회가 주관하여 뛰어난 학생을 선발 할 수 있는지 여부 (1) 있다. (2)한국수학경시대회 (KMO) 위원회를 한국수학교육학회 산하에 구성하여 KMO를 주관하게 하고, 또 국내의 여러 수학경시대회에서 우수한 성적을 나타낸 학생중에서 일정한 인원(50명 정도)을 선발하여 특별히 선정된 훈련팀으로 하여금 조직적인 훈련을 시킨다면 된다. 4. 기타 (1) 과거 어떠한 형태로든 국제 대회에 참가한 경력은 전혀 없다. (2) 1960년대에 서울대학교 공과대학 학생회에서 주최한 수학경시대회가 있었으나 보잘것이 없었고, 현재에도 각 시도별 또는 대학주관의 경시대회가 있으나 거국적인 호응을 받지 못했다. 물론 국제 대회에 참석시키는 것은 엄두도 내지 않았다.
