Relates to physical parts of a building or structure often unseen but crucial for stability.

Construction Focus

Substructure is typically hidden, as it supports from the foundation level or below.

Invisibility

Can be a metaphor for fundamental systems or frameworks in various contexts.

Metaphorical Use

In computing, signifies how data or operations are organized within a larger system.

System Organization

Reflects hierarchical organization, indicating different levels within a structure.

Hierarchy

In network architecture, substructure can refer to a layout of interconnected components.

Network Design

In chemistry, it's specific to parts of molecules with distinct properties or functions.

Chemistry Specific

Focuses on the detailed features of a molecule that defines its characteristics.

Detail Understanding

 In fact, if you look really closely at stuff, if you look at the basic substructure of matter, there isn't anything there. Electrons disappear in a kind of fuzz, and there is only energy. And you can't see energy. So everything that matters, that's important, is invisible. One slightly silly thing that's invisible

 at least not without difficulty, and the closer we look at anything, the more it disappears. In fact, if you look really closely at stuff, if you look at the basic substructure of matter, there isn't anything there. Electrons disappear in a kind of fuzz, and there is only energy.
