Why Quantum Mechanics Exists: An ISL Derivation

For over a century, Quantum Mechanics (QM) has been treated as a set of axioms. We are told that position and momentum do not commute, but rarely why.

The Copenhagen Interpretation says “don’t ask.” The Many-Worlds Interpretation says “everything happens.”
ISL says: “It’s a memory management issue.”

Deriving Heisenberg Uncertainty

In the ISL framework, we treat the universe as a computational system with a finite “bit-budget” per unit volume.

Let C be the cost of describing a state (x, p).

C \propto \log_2\left( \frac{1}{\Delta x \cdot \Delta p} \right)

As precision increases (\Delta x \to 0), the Cost C \to \infty.
According to the Inverse Scaling Law (Gain / (1 + Risk)), the kernel must refuse to instantiate a state where Risk exceeds Gain.

Therefore, there is a hard floor on resolution:

\Delta x \cdot \Delta p \ge \frac{\hbar}{2}

This is not a property of the particle. It is the System Buffer Size. The universe refuses to resolve a coordinate finer than its own grid.

The Quantum Commutator

Why do we need complex numbers? Why i?

[\hat{x}, \hat{p}] = i\hbar

This equation is usually derived from abstract algebra. In ISL, we derive it from Architecture Latency.

1. Modularity: To prevent Authority Collisions (Law 2), Storage (Position) and Execution (Momentum) are handled by separate, isolated modules.
2. Bus Transfer: Moving data from Storage to Execution takes one clock cycle.
3. Phase Shift: The imaginary number i represents a 90-degree temporal rotation—the “tick” of the transfer.

The non-commutativity (xp \neq px) is simply the statement that Time Exists. You cannot access the value of a variable and its rate of change in the same atomic operation without a synchronization cost.

Conclusion

Quantum Mechanics is weird only if you assume space is continuous. Once you accept it is a Resource-Bounded Information System, QM becomes the only logical way to build a universe.
