光の科学−未来を照らす究極の技術とアイデア（学術俯瞰講義） 五神 真 他 教養学部・総合文化研究科 2012 冬学期 Science for Light－Supreme technology and ideas for an illuminating future (Global Focus on Knowledge) Makoto Gonokami and others Arts and Sciences, 2012 Winter
Light is the source of life. The culture and civilization of human beings have been developing in a close linkage with light. People have been watching nature through light since the dawn of their history, and have been observing objects in various levels of scale, from stars to microscopic things. They have also clarified a great deal of nature’s mechanism through such observation. The very basic question about what light is led us to the discoveries of modern physical foundations – quantum theory and the theory of relativity. Since the invention of the laser in the late 20th century, optical technology has not just been leading advanced sciences but also supporting social infrastructures as one of the fundamental technologies. As the “eyes” of scientific observations, optical technology has advanced so greatly that it can now capture a phenomenon lasting only for one-quadrillionth of a second or help us monitor human brain activity without doing anything intrusive. Light is widely used as the ultimate “hands” to manipulate materials. It is also applied to the creation of an extremely high-temperature and high-pressure state equivalent to the inside of a star through focusing of its energy on a very tiny space. Light makes it possible to control the behavior of substances with astonishing accuracy by cooling them to ultra-low temperatures. Modern information networks rely on light as the footman for carrying data. Very strange characteristics of faint light have shown signs of the possibility to develop ultimately secure information technology. These latest optical technological developments can easily be found in our daily lives as well. New optical technology such as lighting provides us with novel visual experiences and creates special spaces to enrich our mental activities. In that sense, it is art. Light is used in many fields as the so-called “all-rounder.” This course is aimed at introducing the latest situation of light science from various viewpoints.
