Using visual and geometric properties to simplify problems.
Using "Fermi questions" and simple physics to get ballpark figures. Thinking About Equations: A Practical Guide for...
Exercises and examples are grouped by the mathematical strategy they illustrate rather than by scientific subfield, which helps in recognizing patterns across different disciplines. Target Audience Using visual and geometric properties to simplify problems
The book aims to help students move beyond just solving for a variable and instead learn to "interrogate" an equation. It provides a "toolbox" of techniques—reminiscent of Richard Feynman's famous "different box of tools"—to analyze, simplify, and verify mathematical expressions in a physical context. Target Audience The book aims to help students
Using units to catch errors or even predict the form of a solution.
Rather than teaching new complex math, it teaches how to apply basic tools (calculus and introductory physics) to gain deeper insight.
It covers essential but often under-taught skills such as:
