#2 Optics and mechanics
Technological development and academic advancement are inseparable. Whenever new technology is created, new phenomena are observed, promoting our understanding of nature. I will explain how development of optics has been affecting technology and other academic fields. How lasers, a typical optical technology, helped realize the world of absolute zero will also be introduced.

#4 Physics and applications of fiber optics
Fiber optics are very thin glass fibers that are as fine as hair. Such a fiber has a refractive index at the core that’s about 0.5 percent higher than that in the areas around the core. Light travels only through this high refractive index area. Fiber optics are so flexible that they can lead light through any shapes or routes. Fiber optics are stronger than piano wires in terms of tensile…

#7 Challenge to realize instant moment－Ultra-short pulse laser
A high-speed shutter system was developed in the late 19th century to answer the question about whether all four legs of a galloping horse do not touch the ground at a certain moment. Scientists now use flashing lasers as shutters and flashes to capture snapshots of changing material at certain points. Researchers are trying to realize at laboratories the same situation as what is believed to be …

#10 What light really is and strange behavior in quantum theory
Once we became able to manipulate very weak light accurately, the real nature of light as both waves and particles at the same time emerged. The situation in which light behaves as waves and particles simultaneously is a world ruled by the quantum theory. In such a world, where our common sense cannot be applied, measurement results of physical phenomena change every time like thrown dice, and tw…
