Welcome to Game Theory
This course provides a brief introduction to game theory. Our main goal is to understand the basic ideas behind the key concepts in game theory, such as equilibrium, rationality, and cooperation. The course uses very little mathematics, and it is ideal for those who are looking for a conceptual introduction to game theory. Business competition, political campaigns, the struggle for existence by animals and plants, and so on, can all be regarded as a kind of “game,” in which individuals try to do their best against others. Game theory provides a general framework to describe and analyze how individuals behave in such “strategic” situations. This course focuses on the key concepts in game theory, and attempts to outline the informal basic ideas that are often hidden behind mathematical definitions. Game theory has been applied to a number of disciplines, including economics, political science, psychology, sociology, biology, and computer science. Therefore, a warm welcome is extended to audiences from all fields who are interested in what game theory is all about.
Visualizing Postwar Tokyo, Part 1
Tokyo emerged out of the ruins of war to become a large city of 10 million people in only a quarter of a century. During this process of change, the capital of a military empire that once invaded East Asia experienced occupation by the U.S. armed forces, hosted the Olympic Games, and transformed into a consumer hub where young people could enjoy economic “wealth.” It is important to know that this process was recorded in countless photographs, documentary films, TV programs, and so on. We will retrieve many of these archived pictures and videos and analyze what happened in postwar Tokyo from different perspectives. In Part 1, you will look at the changes that occurred in postwar Tokyo over a quarter of a century from four different perspectives: 1) occupation and Americanism; 2) imperial gaze and royal wedding; 3) The Olympic city; and 4) economic-cultural clash in Shinjuku. This examination of urban history will provide you with the insights necessary when considering changes in other large cities in Asia, such as Seoul, Beijing, and Bangkok, at the end of the twentieth century.
Visualizing Postwar Tokyo, Part 2
The history of postwar Tokyo reveals an essential feature of the modern city, i.e. the city as a place of visualities. In postwar Tokyo, countless gazes fell upon others; gazes from and upon Americans and the Emperor, gazes going up skyscrapers or rushing aggressively through the cityscape, and gazes twining and wriggling among classes, genders, and ethnic groups in downtown Tokyo. In Part 2, we will focus on the geopolitics of these gazes in modern Tokyo. What kinds of gazes fell upon the war orphans, the poor, and the marginalized groups in Tokyo? How did students themselves, who represented the vast accumulation of knowledge in Tokyo, perform in front of these gazes? Moreover, how did cinema or television shows, as media for these gazes, implicate the whole city? In answering these questions, we will identify the geopolitics historically involved in the practice of “visualizing postwar Tokyo.”
From the Big Bang to Dark Energy
We have learned a lot recently about how the Universe evolved in 13.8 billion years since the Big Bang. More than 80% of matter in the Universe is mysterious Dark Matter, which made stars and galaxies to form. The newly discovered Higgs-boson became frozen into the Universe a trillionth of a second after the Big Bang and brought order to the Universe. Yet we still do not know how ordinary matter (atoms) survived against total annihilation by Anti-Matter. The expansion of the Universe started acceleration about 7 billion years ago and the Universe is being ripped apart. The culprit is Dark Energy, a mysterious energy multiplying in vacuum. I will present evidence behind these startling discoveries and discuss what we may learn in the near future.
Interactive Computer Graphics
Computer graphics can be a powerful tool for supporting visual problem solving, and interactivity plays a central role in harnessing the users' creativity. This course will introduce various interactive tools developed in computer graphics research field with their design rationales and algorithms. Examples include enhancements to graphical user interfaces, authoring tools for 2D drawings and 3D animations, and interactive computer-aided design systems. Rich live demonstrations and course assignments will give you insights and skills to design and implement such tools for your own problems.
Quantum Mechanics of Molecular Structures
Knowing the geometrical structure of the molecules around us is one of the most important and fundamental issues in the field of chemistry. This course introduces the two primary methods used to determine the geometrical structure of molecules: molecular spectroscopy and gas electron diffraction. In molecular spectroscopy, molecules are irradiated with light or electric waves to reveal rich information, including: Motions of electrons within a molecule (Week 1), Vibrational motions of the nuclei within a molecule (Week 2), and Rotational motions of a molecule (Week 3). In the gas electron diffraction method, molecules are irradiated with an accelerated electron beam. As the beam is scattered by the nuclei within the molecule, the scattered waves interfere with each other to generate a diffraction pattern. In week 4, we study the fundamental mechanism of electron scattering and how the resulting diffraction images reveal the geometrical structure of molecules. By the end of the course, you will be able to understand molecular vibration plays an important role in determining the geometrical structure of molecules and gain a fuller understanding of molecular structure from the information obtained by the two methodologies.
