The Subterfuge of Epsilon and Delta
The epsilon-delta proof, the nemesis of many a calculus student, is an initiation rite into the mysteries of proof writing.
Mathematics: learning it, doing it, celebrating it.

Move over, four-color theorem! It's time for the one-cut theorem: You can cut out any shape you want with one cut if you're willing to do some clever folding
What does it mean to understand a mathematical object? I didn't truly believe in the house with two rooms until I built it for myself.
In his new book Creating Symmetry , Frank Farris uses ideas from advanced mathematics, such as complex analysis and abstract algebra, to transform snapshots of landscapes, flowers, or even his dinner into beautiful repeating designs. ...
The provably undrawable line with two origins illustrates a simple but important topological property
The concept of the open set is fundamental in topology. What is it, and why does it matter?
David Madore's online mazes let you explore complicated hyperbolic surfaces from the comfort of your favorite web browser.
Make a yourself or your favorite mathematician into a work of art as a tiling of the hyperbolic plane.
Topology is all about squishing and stretching; distance shouldn't matter. But the infinite earring illustrates the delicate interplay between topology and geometry.
