Why “nucleus” is a great word
The central and most important part of an object, movement, or group, forming the basis for its activity and growth. From Latin nucleus ("kernel, seed"), a diminutive of nux, nucis ("nut"), first attested in English c. 1704 for 'kernel of a nut' and c. 1708 for 'head of a comet.' Unlike "core," which suggests an abstract, indispensable heart, or "hub," which implies a busy junction of connections, nucleus denotes a generative, structural seed. It is the dense, spinning center of an atom, the coiled library of genetic code within a cell, and the committed few from whom a revolution germinates—the minimal, potent kernel from which all complexity unfolds.

Etymology
Learned borrowing from Latin nucleus (“kernel, core”). The earliest uses refer to the head of a comet and the kernel of a seed, both recorded in Lexicon Technicum in 1704. The sense in atomic physics was coined by British scientist Michael Faraday in 1844 in a theoretical meaning.
