Science Cafe Online 2023

Are you a high school or undergraduate student who has a passion for science? Then join us for the third School of Science Café and learn about exciting and topical research being conducted at the School of Science. At this event, you will also get the rare opportunity to interact with UTokyo professors and ask them your questions about research and student life at the School of Science, all from the comfort of your own home.

This online event will be held entirely in English and is open to students worldwide. We hope to see you there!

Samples returned from carbonaceous asteroid Ryugu

Shogo Tachibana, Professor,
Department of Earth and Planetary Science

— About the Speaker —
Shogo Tachibana is a professor at the School of Science, the University of Tokyo. He is interested in what was responsible for making diverse Solar System planets, including Earth. He has especially aimed at understanding the chemical evolution of the early Solar System by combining laboratory experiments, analysis of extraterrestrial materials, astronomical observation, modeling, and Solar System exploration.

C-type asteroids have been hypothesized as parent bodies of carbonaceous chondrites that contain volatiles such as water and organics and record the early chemical evolution of the Solar System. The JAXA’s spacecraft Hayabusa2 returned ~5 gram of sample from C-type asteroid Ryugu. The analysis of Ryugu samples has shown that Ryugu is the chemically most pristine sample, of which elemental abundance corresponds to the solar elemental abundance and that Ryugu sample experienced high degree of aqueous alteration resulting in coevolution of minerals and organic matter. Because the sample has not suffered terrestrial weathering that affected meteorites on the Earth, Ryugu sample is the best window to investigate the origin and chemical evolution of the Solar System.

Shinpei Kato, Associate Professor,
Department of Information Science

— About the Speaker —

Shinpei Kato is an associate professor at the School of Science, the University of Tokyo. His expertise includes computer architectures and operating systems for embedded and real-time systems as well as parallel and distributed systems. He also works as the founder and CTO of Tier IV, Inc., the co-founder and chairman of the Autoware Foundation.

This talk will discuss how scientists are developing the latest computing platforms. What operating systems and software can help run high-level applications such as self-driving cars? Learn about the information technology that powers self-driving cars and more. .
