Superstring theory advances are related to Yukawa's space-time ideas
Noncommutative space-time is crucial in modern theoretical physics
Historical perspective enriches understanding of current theories
Abstract
Yukawa's space-time approach is briefly summarized, which starts just before his meson theory and finally comes to the theory of elementary domain. Recent rapid development in superstring theory is reviewed, focussing our attention on several important topics, which seem deeply related to Yukawa's concern. The importance of the idea of noncommutative space-time is emphasized.
