Definition of fusion

The word "fusion" originated from a scientific concept describing the process by which two atomic nuclei combine to form a single, more stable nucleus. The term "nuclear fusion" was introduced in the 1930s by the British physicist James Chadwick to describe this phenomenon. However, the use of the term "fusion" to describe other processes that involve the combination of elements or ideas did not become popular until the mid-20th century. In the 1950s, the term was adopted by scientists in the field of chemistry to describe the synthesis of complex molecules, such as proteins, from simpler components. In the 1960s, the term began to be used more broadly in various fields, such as architecture, art, and music, to describe the merging of different styles or techniques. Since then, "fusion" has become a widely used word to describe the integration of separate elements into a cohesive whole. In summary, the origin of the word "fusion" can be traced back to the scientific concept of nuclear fusion, but its usage has evolved over time to describe a variety of processes in different fields.
