Most real problems are too complex to solve exactly. The physicist’s move: assume the problem is a small change from a solvable one. Write the solution as ( S = S_0 + \epsilon S_1 + \epsilon^2 S_2 + \dots ) and solve order by order. This thinking process requires recognizing what is small (e.g., coupling constant, inverse distance) and trusting that higher-order terms won’t dominate.

Before solving a differential equation, a physicist often asks: What are the units of the answer? By combining relevant physical constants (e.g., ( G, c, \hbar )) into a quantity with units of length, time, or mass, one can often guess the form of a result without solving a single equation. This thinking process — dimensional reasoning — is a filter for nonsense and a generator of hypotheses. Spivak | Deep, rigorous thinking about physical axioms
