Each person is a diode — a one-directional interpreter that passes the part of an idea aligned with their direction and blocks the rest. Stack a few (specialists re-deriving the same deep thing across fields) and the source comes out different — rotated through each direction in turn. Not better, not worse, not degraded: the same parts, re-pointed. And you can inject a new idea at any moment — the stack restarts with the new source folded in.
A diode passes current one way and blocks the other. A person does the same to an idea: they pass the component that fits their field's direction and block what doesn't. "Everyone only cares about their direction" — so an idea passing through a person comes out re-oriented toward that person's axis. Not corrupted. Re-pointed.
Stack three diodes — three specialists re-deriving the same deep structure (the "quantum Planck stuff," each in their own words). The source passes through three directions in sequence and exits different: field C's projection of field B's projection of field A's projection. Same parts the whole way; only the orientation turned. That's why re-derivations across fields look different yet are recognizably the same source — they're one vector read along several axes.
The system is open. At any stage you can inject a new idea — and it doesn't append, it restarts the process with the new combined source. The new idea folds into whatever state the stack had reached, becoming a new source that re-projects through the whole stack again. The result is never frozen: every injection re-derives the whole thing from the new parts. Not better, not worse — reconstituted from the parts now provided.
