Science Talk
 
These are special lectures on science. There will be 6 Talks for you to choose from.
 
 
T-1 With more light or less – how to decipher the mystery of the universe
Dr. Saeko S. Hayashi.Thirty Meter Telescope Project Office,
National Astronomical Observatory of Japan
Also Department of Astronomical Science,
SOKENDAI (The Graduate University for Advanced Studies)
How do you study the universe – visible and invisible? With simple demonstration tool, the participants of this course will “peek” into or get a grasp of means of modern astronomy. The challenge is how to map the dark matter – by definition it does not emit any electro-magnetic waves, as well as the more elusive dark energy. The visible universe, or the ordinary matter that interact with light, makes only 4 % of this universe. The rest is left to you, the future generation of scientists and engineers. Since the targets of the astronomy are all out in space and difficult to observe, cooperation amongst the professionals from countries around the world is very important. I am looking forward to seeing you from different part of this planet.
 
T-2 “Blue lights” on your Brain: Good blue lights and bad blue lights
Dr. Amane KoizumiNational Institutes of Natural Sciences
For your brain, blue lights are important especially for recognizing color, because blue is one component of three color theory. However, besides color recognition, blue lights have two more aspects, so-called good blue lights and bad blue lights, based on distinct mechanisms. By showing some optical illusions, I will discuss how blue lights are important for your brain function and how we could protect your eyes from bad blue lights.
 
T-3 Challenging human fuzzy sense with chemistry and physics: Mechanism of Olfaction
Dr. Takashi KurahashiOsaka University / Mie University
Dr. Hiroko TakeuchiOsaka University
It is generally thought that the sense of smell is a kind of fuzzy sensation, although olfaction itself plays indispensable roles in human life. The biggest reason why we do not pay attention to olfaction is that this system skips the recognition step in the brain, and projects to the deep part of the brain. Because of such neuronal projection, olfactory senses play roles without inducing your recognition. We are able to catch hundreds of thousands of odorants. Pleasant flavors and fragrances bring you a comfortable status, while bad smells induce bad feelings and emotions. In the lecture, we will prepare some samples of odorants so that you can experience several smells emitted from chemical compounds. At the same time, you will receive a lecture regarding the molecular mechanisms of olfactory signal transduction. You will understand the fundamental mechanism of olfaction and how you can discriminate huge numbers of different substances.
 
T-4 Fusion and Superconducting Magnet Technology for Saving the Earth
Dr. Nagato YanagiNational Institute for Fusion Science,
National Institutes of Natural Sciences
/ SOKENDAI (Graduate University for Advanced Studies)
Fusion is the energy that has powered the sun and stars for billions of years. The fusion on earth, the artificial sun, should one day provide an ultimate solution to the world’s energy crisis, since the fuel is taken from the seawater, which is limitless. It would not only mitigate global warming in this century, but also become a viable measure to prepare for the possibility of global cooling in the coming centuries. Fusion research is progressing towards the construction of DEMO reactors in the 2040’s by overcoming some technological difficulties. For fusion, the large-scale superconducting magnet is indispensable. This technology is already used in MRI magnets in hospitals and is going to be also used in many other applications, such as medical accelerators for cancer treatment, magnetically levitated vehicles like the Japan Railway Linear Shinkansen and electrical power grids. A global-scale superconducting magnet system will one day be protecting the earth in the far future.
 
T-5 Science is Fun!
Mr. Dale OliveWaiakea High School
Science concepts can sometimes be difficult to understand. A technique called discrepant events will be used to teach concepts such as air pressure, Newton’s Laws, sound, Bernoulli’s principle and more. Discrepant events are things that happen that are counter intuitive to the observer, like a magic trick. This creates an urge in the observer to understand how the event actually happened, in other words, you’ll be begging to learn how it works. In these science demonstrations that, you can easily replicate in your school to encourage others to become interested in science, laughing is required as you will see how much fun science can be.
 
T-6 Let’s Draw Electronics Circuits Using Circuits Marker
CSR Promotion Committee ROHM Co., Ltd.
What do you think when you hear of “electronic circuits”? Most of you may think that they are difficult, far from reality, complicated and like a maze. Actually, electronic circuits are being used in almost all products that support our daily lives, Such as smart phones, TVs, cars, air conditioners, refrigerators, etc. Electronic circuits make many things possible that make our lives more convenient by Calculating, sending data, turning lights on and off, etc. depending on the combination of Components and circuit paths. This time we will use special pen ink that could become electric paths and draw Electronic circuit on the top of a paper using battery and LED.
