But what is the Fourier Transform? A visual introduction.
Fourier analysis is built around one practical question: given a signal that’s messy in time—like the air-pressure trace from a sound—how can it be...
Cross products in the light of linear transformations | Chapter 11, Essence of linear algebra
The 3D cross product isn’t just a memorized formula—it’s the dual vector of a specific linear transformation built from two vectors v and w. Once...
Cramer's rule, explained geometrically | Chapter 12, Essence of linear algebra
Cramer’s rule gets its power from a geometric fact about determinants: when a linear transformation acts on space, every “coordinate-carrying” area...
Convolutions | Why X+Y in probability is a beautiful mess
Adding two independent random variables isn’t just a matter of “adding their means”—it reshapes their entire probability distribution through a...
Start Learning Complex Numbers 1 | Introduction [dark version]
Complex numbers enter math because real numbers can’t solve the equation x² = −1. In the real number system, every square is always nonnegative—so x²...
