Hydrodynamic Phase-Space Factorizer

This is a conceptual model of a theoretically scalable hydrodynamic computer. It uses a parallel algorithm analogous to Shor's Algorithm, evolving a "superposition" of states through wave interference to form a stable geometric pattern that reveals the factors.

Enter a composite number (4–200) and click "Factorize".

The Comprehensive Concept

This visualization is the culmination of a design process aimed at creating a physical computer capable of solving problems that are intractable for classical computers, such as factoring large numbers. It represents a fundamental shift away from our previous, flawed models, building upon the theoretical framework of the "Hydrodynamic Oracle."

1. The Failure of Previous Models: The Linear Scan

Our earlier designs (the "Resizing Box" and "Resonant Factorizer") were clever but ultimately bound by the rules of classical computing. They relied on a linear scan—checking one potential factor at a time by deforming a box or moving a baffle. This approach fails catastrophically at scale for two reasons:

The core lesson was that a parallel computer is wasted if it's forced to run a sequential algorithm.

2. The New Paradigm: A Physical Analogue of Shor's Algorithm

To achieve scalability, we must adopt a truly parallel algorithm. This model is a physical analogue of Shor's Algorithm, the famous quantum algorithm for factorization. It does not search for factors directly. Instead, it transforms the problem into one of finding the period r of a modular exponential function (a^x mod N).

This computer leverages the inherent parallelism of fluid dynamics and wave mechanics to solve this period-finding problem in a single, global process, avoiding direct trial division.

4. The Computational Process (The "Software")

  1. Superposition Generation: The initial, modulated ripple expands outwards, encoding the problem parameters (N and a) into the wave's phase and frequency components. This creates a physical superposition, where countless computational paths are initiated simultaneously.
  2. Parallel Computation via Wave Dynamics: The wave reflects and propagates within the tuned cavity, undergoing self-interference. This is where the core computation occurs. The carefully engineered system ensures that the wave's phase evolution, including reflections, is analogous to the `a^x mod N` function. Every possible computational path (every `x` value) evolves in parallel through the natural physics of wave propagation.
  3. Measurement via Constructive Interference: Through the principles of wave mechanics, paths that are "out of phase" destructively interfere and cancel out. Crucially, paths that are "in phase" (because they share the same mathematical period r derived from `a^x mod N`) constructively interfere, amplifying each other. This physical phenomenon acts as a global Fourier Transform, highlighting the dominant periodic component.
  4. The Solution Pattern: The system naturally settles from a chaotic interference phase into a stable, geometric pattern (akin to a Chladni figure). The symmetry of this pattern—specifically, the number of distinct "arms" or lobes—directly reveals the period r of the modular exponential function. Rigorous measurement techniques (e.g., 2D Fast Fourier Transform analysis of the final pattern) can objectively extract this value.
  5. The Classical Hand-off: Once the period r is precisely measured from the stable pattern, a classical computer can use this value, along with N and a, to find the prime factors of N almost instantly using well-known classical algorithms (e.g., Euclidean algorithm).

5. Why This Model is Theoretically Scalable

This design overcomes the limitations of the previous models, aligning with the principles of the "Hydrodynamic Oracle" research:

A Note on This Visualization

This HTML page is a conceptual visualization, designed to illustrate the core principles of superposition, interference, and pattern formation. It abstracts away the highly complex physics of encoding N and a into the initial wave and the precise dynamics of the `mod N` operation within the fluid. The JavaScript here is a simplified demonstration that sets the final pattern based on pre-calculated factors and period, rather than simulating the full period-finding process. A true physical implementation would be a subject of advanced research in fluid dynamics, wave computing, and computational physics, building directly on the theoretical work of the "Hydrodynamic Oracle" and its virtual proofs of concept.
