Mathematical Science Course

Students learn systematically basic mathematical theory and engage in practical exercises such as mathematical model analysis and data analysis so that they develop skills of solving problems in natural and social systems.

Materials Physics and Astrophysics Course

This course focuses on the fields of functional materials physics and astrophysics, and provides education to promote interest in the fundamental laws of nature and their practical application in industry and society.

Applied Computational Science Course

Students learn basic mathematics, physics, and information science with the aim to understand social phenomena and to solve problems of social and economical systems.


Voice of undergraduate

The thesis of my graduate research was Projecting the earth’s ellipsoid revolution onto a flat plane

Department of Mathematical Sciences 4th grader (2017)
KON, Yoshiki

Since I had studied about bent space at a seminar in my third year, I had begun to work on a map projection method to show bent space on a flat surface. I continued this research and eventualy made it the thesis of my graduate research.
By looking at the earth as a ellipsoid revolution, rather than viewing it as spherical, a more accurate map can be prepared.
There are many difficult theorums and calculations regarding the theory of the geodesic line, which is the shortest route on a bent surface, and the theory of map projection.
I felt rewarded in my research when I was able to clearly define a theorem proof, and by changing my viewpoint I realized that there are other proofs as well.
