How Infinity Explains the Finite
Peano arithmetic proves many theories in mathematics but does have its limits. In order to prove certain things you have to step beyond these axioms. Sometimes you need infinity.

Counting To Infinity And Beyond On A Chessboard
The numbers "infinity plus 1" and "infinity squared" sound like they are made up, but mathematicians do use such numbers in set theory. They are called transfinite ordinals and they arise in combinatorial game theory. This video...

Kill the Mathematical Hydra
Feel like Hercules for a day. Individuals watch a video that describes how to defeat a mathematical Hydra that grows additional heads when one is cut off. The solution requires scholars to use ordinals and the well-ordering theorem.

How Infinity Explains the Finite
Using infinity to prove a sequence is finite sounds counter-intuitive, doesn't it? Scholar learn about hereditary base notation and the Goodstein sequence. They discover that proving the Goodstein sequence is finite requires infinite...

Infinite Chess
Imagine an infinitely-large chess board with an infinite number of pieces. Pupils learn about infinite chess and how it is a determined game, in that there is always a winning strategy. The video first applies Zermelo's Theorem to show...
