1935年在日本诞生了核力介子理论。1945年也是在日本释放了核力。1935年汤川秀树宣布了一种新的基本粒子的预言,其质量在电子质量和质子质量之间,后来命名为“介子”,意思是说介乎于中间的粒子,用来解释在原子核里结合核子的力(质子和中子)。介子已成为三种基本粒子之一,另外还有baryon(重子、包括核子)Lepton(轻子如电子和中微子)。然而介子和重子不再被看作是最基本的粒子,因为今天它们被认为是由夸克构成。虽然汤川秀树从来没有离开过日本去国外,可他在预言介子存在时,他和同事的研究有助于展开了20世纪初西方科学的国际扩展。1949年,汤川秀树获得诺贝尔物理奖时,他已经在日本建立了兴盛的基本粒
In 1935 in Japan, the nuclear force meson theory was born. In 1945, Japan also released nuclear power. In 1935, Hideki Yukawa announced a new prophecy of elementary particles whose mass lies between the mass of electrons and the mass of protons and was later named “meson”, meaning particles in between, which are used to explain the binding in the nucleus Nuclear forces (protons and neutrons). Mesons have become one of three basic particles, in addition to baryon (baryons, including nuclei) Lepton (leptons such as electrons and neutrinos). However, meson and baryon are no longer seen as the most basic particles, because today they are considered to be composed of quarks. Although Hideki Yukawa had never left Japan to go abroad, but he predicted the existence of a meson, the study of his and his colleagues helped launch an international expansion of Western science in the early 20th century. In 1949, Yukawa Tomokazu won the Nobel Prize in Physics when he established a flourishing elementary grain in Japan
