What is a MOOC ?
Massive Open Online Courses (MOOCs) are free online courses that anybody can take, and those who complete the course can earn an official certificate for a fee. Top universities around the world offer MOOCs, and the total number of registered learners on the Coursera and edX platforms has reached more than 130 million. Along with self improvement, learners are using MOOCs to improve their professional skills, and the individually validated certificates are helping learners advance in the workplace and make career changes.

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.
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.
Basic Analytical Chemistry
Analytical chemistry takes a prominent position among all fields of experimental sciences, ranging from fundamental studies of Nature to industrial or clinical applications.Analytical chemistry covers the fundamentals of experimental and analytical methods and the role of chemistry around us. This course introduces the principles of analytical chemistry and provides how these principles are applied in chemistry and related disciplines - especially in life sciences, environmental sciences and geochemistry. This course, regardless of your background, will teach you fundamental analytical concepts and their practical applications. By the end of the course, you will deeply understand analytical methodologies in a systematic manner. Finally, this course will help you develop critical, independent reasoning that you can apply to new problems in chemistry and its related fields. This course is for anyone interested in analytical sciences.
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.
