If I asked you to draw a curve—a simple line from Point A to Point B—you’d probably draw a smooth arc or a wavy line. You’d leave plenty of empty space on the page.
Meet the . The Problem With "Simple" For most of mathematical history, "curve" meant something tidy: a circle, a sine wave, a parabola. But in 1890, Italian mathematician Giuseppe Peano dropped a bomb. He constructed a curve that passes through every point of a unit square. monster curves
Take a 1x1 square. It contains an infinite number of points. Peano built a single, continuous line that touches every single one of them . If I asked you to draw a curve—a
A line can, in fact, behave like a square. The distinction between one and two dimensions depends on how you define "distance" and "covering." The Problem With "Simple" For most of mathematical
Let that sink in.
But what if I told you that mathematicians have discovered curves that are so wild, so twisted, and so impossibly long that they can literally fill up a entire square? Not a thick marker blob. A true, one-dimensional line that visits every single point inside a two-dimensional area.
As mathematician Hans Hahn once put it: "The concept of a curve is far richer and more terrifying than anyone had imagined." You don't need infinite iterations to see the beauty. Open a simple Python environment (or even a spreadsheet) and generate the first 4 iterations of the Hilbert curve. Plot the points. You'll see a beautiful, orderly maze that slowly begins to eat the empty space.
