The Life of the Sea, the Life of the Stars, and the Life of Human Beings

Rhythm runs through it."

Water, stars, and animation are things we see without thinking about them. What kind of research is currently being conducted at the Faculty of Science in these familiar fields?

In this lecture, we will introduce the latest research in earth science, astronomy, and information science, as well as the mysteries that have yet to be solved and the challenges that lie ahead.

The slide presentation (PDF) is no longer available.

Deep Ocean Currents Guided by the Moon: Challenges to the Mystery of Deep Ocean Circulation Around the Earth

Noriyuki Hibiya (Professor, Department of Earth and Planetary Physics, Department of Earth and Planetary Environmental Science)

- Career Background - Professor, Department of Geophysics and Planetary Physics, University of Tokyo

D. from the Graduate School of Science, the University of Tokyo, Research Associate at the Earthquake Research Institute, the University of British Columbia, Postdoctoral Fellow at the University of Washington, Associate Professor at the Graduate School of Science, Hokkaido University, Assistant Professor at the Ocean Research Institute, The University of Tokyo, and Assistant Professor at the Graduate School of Science, the University of Tokyo before assuming his current position in 2000. D. (Science).

Deep water, which is strongly cooled and deposited in the polar regions, travels around the globe for about 1,500 years, upwells in the Indian and North Pacific Oceans, and returns to the polar regions, forming a deep ocean circulation like a conveyor belt. The heat transport from low latitudes to high latitudes associated with the circulation plays an important role in the formation of the Earth's temperate climate. Although buoyancy injection from the surface to the deep layer by turbulent mixing is considered essential for upwelling of deep water necessary to maintain this circulation, turbulent mixing has not yet been found to upwelling all deep water, which is estimated to sink 20 million tons per second, to the surface (Missing Mixing). In this presentation, I will introduce the important role of the moon (tides) in the formation of this turbulent mixing as well as the challenge to solve the mystery of the Missing Mixing.

Betelgeuse -Life and Fate of the Red Supergiant Star in Orion

Hideyuki Umeda, Associate Professor, Department of Astronomy

- Biography - Ph.

D. in Department of Physics, University of Michigan, U.S.A., Graduate School of Science (Astronomy), The University of Tokyo, Postdoctoral Fellow at the Early Universe Research Center, The University of Tokyo, 2007-present.

Betelgeuse is a famous first-magnitude star that forms part of the Winter Triangle. Since then, the brightness has returned to normal, and some researchers believe that the star will not explode for the next 100,000 years or so, so the fuss seems to have died down. In this talk, I will give a general explanation of stellar evolution and then compare the latest theoretical calculations with observations to see what can be said about the life and fate of Betelgeuse.

Digital Technology for Creating Attractive Animation Works

Tsukasa Fukusato (Assistant Professor, Department of Information Science)

- Career Background -

D. in Department of Physics and Applied Physics, Graduate School of Advanced Science and Engineering, Waseda University. D. in Physics and Applied Physics from the Graduate School of Advanced Science and Engineering at Waseda University, where he was a Deputy Research Scientist (Assistant Professor) before assuming his current position in September 2017. D. in Engineering.

The method in which the designer draws each picture is widely used to produce animated works that include physical inconsistencies. However, this method has issues related to workflow, which requires a great deal of work time and effort, in addition to the designer's own skills to draw the pictures. In addition, the designer's skills are all empirical, and there is a possibility that the skills themselves will be lost in the future. Therefore, in this presentation, I will introduce research cases aiming at formulation and systemization of technologies in the animation industry from the aspects of computer graphics (CG) and human-computer interaction (HCI) fields.
