In mathematical analysis, some functions are continuous everywhere, and some functions are discontinuous at some points or everywhere. We construct an example of a function continuous at one point only. The proof is based on the fact that rational numbers and irrational numbers are dense in the set of real numbers.

I dedicate this video to the strong and brave Ukrainian people who are fighting for their country and their freedom against Russian aggressors.

The animations for this video are made in Manim Community Edition, which is a fork of the original Manim package that Grant Sanderson uses to make his videos for the 3blue1brown YouTube channel.
