Aiming at a more rigorous understanding in electrical insulating materials research

In order to fully understand a certain property of a material or to clarify the mechanism of a phenomenon, research must be done with scientific rigor and a scholarly approach. The first three pioneers who introduced the rigorous scholarly approach into the field of electrical insulation research in Japan are Profs. Inuishi, Ieda, and Yahagi. Researchers and students have been inspired by their work and have been encouraged by this rich heritage by following in their footsteps. On this occasion of being awarded the Whitehead Memorial Lecture Award, the author is honored to introduce several examples of research done in his laboratory at Waseda University.
