Physics as Computation

Upcoming Saturday Febr 3 at 10 am EST I will give a live presentation at John Chappell Natural Philosophy Society CNPS channel with title:

         PHYSICS as ANALOG COMPUTATION as DIGITAL COMPUTATION 

stating MAIN IDEA:

• REAL WORLD - CONTINUUM MECHANICS MODEL - COMPUTABLE
• REAL QUANTUM MECHANICS - CONTINUUM MODEL - COMPUTABLE
• STANDARD QM: HIGH-DIMENSIONAL SCHRÖDINGER EQ - UNCOMPUTABLE.
• REAL WORLD - COMPUTABLE
• MICROSCOPICS = MACROSCOPICS

  with the following references:

• REAL QUANTUM MECHANICS  REALQM
• TURBULENCE
• THERMODYNAMICS: 2ND LAW     DIRECTION of TIME
• RADIATIVE HEAT TRANSFER: PLANCK'S LAW

with remarks on: 

• SPECIAL RELATIVITY = LORENTZ TRANSFORMATION = UNPHYSICAL 
• GRAVITATION: NO ACTION AT DISTANCE: $\rho =\Delta\Phi$

Key aspect: 

• REAL PHYSICS - ONTOLOGY - WHAT IS - WHAT CAN BE COMPUTED

in opposition to 

• EPISTEMOLOGY - WHAT WE CAN SAY - COPENHAGEN QM

with key ingredients:

• COMPUTABILITY 
• STABILITY - WELLPOSEDNESS 
• FINITE PRECISION 

connecting to: 

• STANDARD QUANTUM MECHANICS = UNCOMPUTABLE
• REALQM = COMPUTABLE 
• TURBULENCE = COMPUTABLE = EULER'S EQUATIONS

modeled by:

• CLASSICAL CONTINUUM MECHANICS MATHEMATICAL MODELS 

including:

• NEWTON'S LAWS MOTION + GRAVITATION
• EULER EQ
• MAXWELL EQ
• REAL SCHRÖDINGER EQ

The mantra of John Chappell Natural Philosophy is 

• WHERE CRITICAL THINKING CHALLENGES THEORY

which connects to the mantra of this blog: 

• TOWARDS UNDERSTANDING BY CRITICAL CONSTRUCTIVE INQUIRY

I look forward to a constructive discussion with free-thinking physicists, in a situation where leading physicists insist on "Shut-up and Calculate". 

PS1 Einstein's No-Aether Special Relativity with its unphysics/paradoxes has attracted much debate recently on CNPS to which I can contribute Many-Minds Relativity as an alternative with physical meaning connecting back to Ebenezer Cunningham's Many-Aethers concept. 

Here different observers moving with different constant velocities are locked to different moving aethers as different Euclidean coordinate systems for expression of Maxwell's equations. The key question is to what extent different observers can agree. 

PS2 Some high-lights:

• Instant local action - explicit time stepping: local force-acceleration-velocity-position: add-mult

• Radiative heat transfer: Not 2-way stream of photons. Instead: resonance mediated by Maxwell. 

• New theory of flight - turbulent Euler: drag lift computable/predictable with slip boundary condition. 

• Quantum mechanics: Deterministic continuum mechanics = physical. Statistics = unphysical.

• Solution concept: Pointwise/strong vs meanvalue/weak.
