Engineering is applied equations. These formulas appear across mechanical, electrical, civil, aerospace, and software engineering — worth knowing deeply, not just memorizing.
Mechanics & structures
Newton's second law (F = ma), Hooke's law, stress-strain relationships, and Bernoulli's equation for fluids. These govern everything from bridges to propellers.
Fields & signals
Maxwell's equations, Fourier transform, and the heat equation. Essential for electronics, communications, and thermal design.
Optimization & data
Gradient descent powers machine learning. Shannon entropy sets information limits. Bayes' theorem guides decision-making under uncertainty.
