In his book, In Pursuit of the Unknown: 17 Equations That Changed the World, Ian Stewart discusses each equation engagingly and practically…

Pythagorean Theorem

$$a^2 + b^2 = c^2$$


$$log{xy} = log{x} + log{y}$$


$$\frac{\partial f}{\partial t} = \lim_{x\to\infty} = \frac{f{(t+h)}- f{(t)}}{h}$$

Complex Numbers


Euler’s Formula for Polyhedra

Normal Distribution

Wave Equation

Fourier Transform

Maxwell’s Equations

$$\begin{aligned} &\nabla\cdot\mathcal{E} = 0 &\nabla\cdot\mathcal{H} = 0 \end{aligned}$$

$$\begin{aligned} &\nabla\times\mathcal{E} = - \frac{1}{c}\frac{\partial\mathcal{H}}{\partial t} &\nabla\times\mathcal{H} = - \frac{1}{c}\frac{\partial\mathcal{E}}{\partial t} \end{aligned}$$
