Kavli IPMU Project Professor Tadayuki Takahashi

Lecture: Cosmic Vision, Cellular Precision: Adapting Space Technology for People

  • Time & Date: 1:00pm - 2:00pm, October 24 (Fri)
  • Venue: Lecture Hall (1F) (note: seats will be allocated on a first come, first serve basis. Once we have reached full capacity, we may not be able to allow any more people inside the venue)

  • Speaker: Tadayuki Takahashi
  • Title: Project Professor, Kavli Institute for the Physics and Mathematics of the Universe
     
  • About this talk:
    Above Earth’s thick atmosphere lies the true face of the universe—a dynamic world beyond imagination. In this lecture, I will introduce how we observe the universe in X-rays and gamma rays using giant balloons and rockets, capturing dramatic phenomena such as black holes and supernova explosions. I will also explain how technologies developed for these cosmic observations have already been applied to detecting radiation hotspots, and how in the future they may help in discovering cancers at their earliest stages inside the human body

Kavli IPMU Professor Hiraku Nakajima

Lecture: Mathematical Legends: Fields Medal History

  • Time & Date: 1:00pm - 2:00pm, October 25 (Sat)
  • Venue: Lecture Hall (1F) (note: seats will be allocated on a first come, first serve basis. Once we have reached full capacity, we may not be able to allow any more people inside the venue)

  • Speaker: Hiraku Nakajima
  • Title: Professor, Kavli Institute for the Physics and Mathematics of the Universe and President, International Mathematical Union
     
  • About this talk:
    The Fields Medal is awarded every 4 years to a handful of mathematicians during the International Congress of Mathematicians. It is the highest honor in mathematics, and as President of the International Mathematical Union, I am currently the Chair of the Fields Medal Committee. This lecture will explore the history of the Fields Medal, its influence on mathematics, and I will recount my personal experience witnessing the 1990 Fields Medal announcement and its mathematics.
     

Project Professor Saeko Hayashi

6. Science for Kids Lecture: How to Catch a Rainbow

  • Time & Date: 11:00am - 11:40am, October 25 (Sat)
  • Venue: Lecture Hall (1F) (note: seats will be allocated on a first come, first serve basis. Once we have reached full capacity, we may not be able to allow any more people inside the venue)

  • About this talk:
    Hello everyone, when was the last time you saw a rainbow? You may have noticed that rainbows appear across from the sun after it has stopped raining. Sometimes you can see them within a drop of water sitting on a leaf, or reflected in a puddle on the way to school. Why do we see rainbows, and how are they connected to the Sun? In this talk, we will use a small gadget that will help us see a rainbow, maybe even on your palm. Then we can start exploring what a rainbow is. The science behind a rainbow, is in fact very important to big science gadgets like the Subaru Telescope. The telescope doesn't study our Sun, but it is looking at the light from stars very far away from us. What can their light tell us? Join me in exploring objects far, far away in the universe!  

Science Onsen 


While "science cafes" began in England, we have adapted the concept and present a Japanese-style "science onsen" or "science hot spring".

  • Time & Date: 3:00pm - 4:00pm, October 25 (Sat)
  • Speakers: Coming soon
  • Venue: Lecture Hall (1F) (note: seats will be allocated on a first come, first serve basis. Once we have reached full capacity, we may not be able to allow any more people inside the venue)
