a self-contained brick that lets you build cathedrals without understanding the whole blueprint.

means A self-contained unit designed to be combined with others to build a larger system, whether in software, hardware, furniture, or coursework.

from From Latin 'modulus,' a diminutive of 'modus' (measure, manner) — literally 'a little measure.' It entered architecture first, naming a standard unit of proportion used to keep a building's parts in harmony, before the 20th century lent it to engineering, computing, and spacecraft, where it came to mean any standardized, swappable component.
