The Laws of Fermi Problem Solving (v4)

A Framework for Human-AI Collaborative Estimation

---

Introduction

Fermi problems challenge us to estimate quantities with limited information, relying on logical reasoning and approximate data. These methods, pioneered by physicist Enrico Fermi, are invaluable in science, engineering, and everyday problem-solving.

This framework codifies the methodology from Lawrence Weinstein's Guesstimation books into a structured set of laws that enable effective human-AI collaboration on estimation problems. The mechanical laws (LAW0-LAW11) handle arithmetic and formatting. The estimation laws (LAW-INTERPRET, LAW-ESTIMATE, LAW-BOUNDS, LAW-PROCEED, LAW-DECOMPOSE, LAW-VALIDATE, LAW-REPORT) address the critical judgment layer: knowing when and how to guess, and when to ask for help.
