物理分两种,一种是宏观物理,不涉及亚原子的变化,一种是微观物理。微观物理研究亚原子粒子的各种属性和变化。物理学的终极目标就是搞清楚构成这个世界的最基本的粒子及其是如何构成整个宇宙的,质能转化就是物理学的一个现象(难道爱因斯坦研究的不是物理学?)。下面是国际原子能机构关于放射性裂变的说法--it is a physical phenomenon

Radioactivity is the term used to describe disintegration of atoms. The atom can be characterized by the number of protons in the nucleus. Some natural elements are unstable. Therefore, their nuclei disintegrate or decay, thus releasing energy in the form of radiation. This physical phenomenon is called radioactivity and the radioactive atoms are called nuclei.
