Reception and Outcome

  Professor Sheldon Lee Glashow stayed in Japan for 12 days this time, during which period he gave two different lectures in English at each of two different locations, thus delivering four lectures in total. He also visited three research institutions, had a talk with Professor Masatoshi Koshiba, one of the recent Nobel Prize laureates in physics, paid a courtesy visit to and had discussions with the president of the Japan Society for The Promotion of Science, and also had informal discussions both with Sadakazu Tanigaki, Minister of State for Industrial Revitalization Corporation of Japan, and with Hiroyuki Hosoda, Minister of State for Science and Technology Policy, thus accomplishing a wide variety of activities, including talks with numerous researchers.

  The original title of the lectures he delivered at Tohoku University and Kyoto University was "The Role of Serendipity in Science", the contents of which were oriented toward undergraduate and graduate students majoring in science. Posters were prepared for these lectures with the title translated into Japanese: the one for a lecture at the Tohoku University was the exact translation of the original title, and the other for a lecture at the Kyoto University was "Discovery in Science, and Inspiration." Approximately 400 people gathered at the former place, while approximately 300 people gathered at the latter. Both lectures were very well attended. In his lectures, Professor Glashow explained that the development of science does not necessarily take place as planned or envisioned, but chance frequently plays a critical role; he exemplified numerous cases, including the achievement of Professor Masatoshi Koshiba, the Nobel Prize laureate in physics, thereby emphasizing that the government and industries have to recognize squarely this particular aspect. This lecture left a profound impression on the audience.

  The original title of another lecture he gave is "Neutrinos: What Are They and Why Do They Fascinate Us?" which sounded rather challenging, and was delivered to an audience formed by the general public at the Capitol Tokyu Hotel in Tokyo, while its junior version, more softly entitled "Neutrinos: Their Identity and Mystery", was delivered to high school students at the Hida-kamioka Senior High School in Kamioka, Gifu Prefecture. In these lectures, he dealt with the history of the discovery of neutrinos and the characteristics of neutrino particles, explaining them in plain words. He continued with an appreciation of the contribution of Japan to the area of neutrino physics achieved by Kamiokande, Superkamiokande, and KamLAND experiments. Before ending his speech, he specifically pointed out the importance of conducting long baseline neutrino oscillation experiments at the Japan Proton Accelerator Research Complex (J-PARC). Thus, his lectures were very interesting, and the post-lecture discussions developed enthusiastically.

  He had been looking forward to visiting the Kamioka underground observatory. Although he had visited Kamiokande in 1986, the current visit of Superkamiokande was a first for him. He toured, showing great interest, walking around the experimental site which had brought about the significant discovery in the area of neutrino physics. In addition, he visited kamLAND facility of the Tohoku University, which was constructed utilizing the space previously used for the Kamiokande facility; there he met several researchers, who were from the United States and whom he therefore personally knew. Thus, he received in-depth explanations from them, and had useful exchanges with them. After completing his tour of this observatory, which has been achieving spectacular results in the most advanced areas of neutrino physics, he mentioned to the researchers working at the site that Japan should implement the research plans which follow (i.e., long baseline neutrino oscillation experiments), which may provide a boost to the already high momentum gained in this particular area, as early as possible. This was very encouraging.

  During the talks he had with government officials, Professor Glashow emphasized the existence of latent power in Japan in the basic sciences, exemplified by the four Japanese scientists who were granted the Nobel Prize for three consecutive years, and he particularly referred to the research and development of an electron-positron linear collider, which Japan has been greatly contributing to, and which is expected to be the most advanced next-generation facility specialized in particle physics. Moreover, he mentioned the importance of conducting long baseline neutrino oscillation experiments at J-PARC, and the superiority of Japan in this particular area. His points appeared to be greatly useful in deepening the relevant government officials' understanding of basic sciences in general and of high-energy physics in particular, and in winning the sympathy of these government officials.

Contributions made by the invited researcher to the institution involved in the reception

(Stimulation to young researchers, globalization of the entire body of the receiving institution, etc.)

  The High Energy Accelerator Research Organization responsible for receiving the invited researcher is the institution that represents the area of high-energy physics in Japan. It cooperates with various research institutions in Europe and the United States, and at the same time competes with them vigorously. Among other things, this organization has a lead in the neutrino research with the world's first long baseline neutrino oscillation experiment, K2K, as well as with a next-generation experiment plan using the High Intensity Proton Accelerator at J-PARC. Also, it positions itself at the frontline, together with overseas institutions, of the research and development of an electron-positron linear collider, in pursuit of new frontiers in high-energy physics. The community of high-energy physicists in Japan strongly hopes that this accelerator will be constructed as a next-generation base facility in Japan. Having talks with the government, the industries, and the mass media, and explaining in plain words the importance of this technology in his speech to the general public and students, Professor Glashow, who is familiar with both of these two important plans, strongly supported their promotion, and thus urged proper understanding and full support of this project. Clearly, the words given by a globally distinguished scientist such as Professor Glashow have generated great momentum toward the promotion of these plans.

  The lectures given by Professor Glashow to the undergraduates of the Department of Science and graduates of the Graduate School of Science at the Tohoku University and Kyoto University, and the post-lecture discussions he developed, created a strong intellectually stimulating effect on the youths who are poised to shoulder the next generation. They were deeply impressed. During the tour of the Kamioka underground observatory, he put aside some time for talking to young researchers both from the University of Tokyo (researchers related to the Superkamiokande project) and from the Tohoku University (researchers related to the kamLAND project). Friendly talks with one of the founders of the modern particle physics, about whom these young researchers had only read about, were priceless experiences scarcely hoped for, giving them strong motivation for their research.
