Checking if an equation makes sense at extremes (e.g., zero or infinity). , written by Matt A
Rather than teaching new complex math, it teaches how to apply basic tools (calculus and introductory physics) to gain deeper insight. Core Premise Using visual and geometric properties to
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.
Using "Fermi questions" and simple physics to get ballpark figures.
