Euclidean Hurwitz algebra

Imagine you have blocks of different sizes and colors, and you want to combine them in different ways. But you also have some rules that you must follow so that everything makes sense.

A Euclidean Hurwitz algebra is like a set of rules for these blocks. Each block has a certain size and color, and there are different operations you can perform on them, like adding, subtracting, multiplying or dividing them.

Now, here comes the trick: these rules are special because they can be used to describe some important mathematical concepts and ideas, like geometric objects or numbers with weird properties.

For example, a Euclidean Hurwitz algebra can help you understand what a complex number is or how you can represent rotations in space using quaternions. It's like a secret code that makes sense only to people who are really good at math, but it can be a powerful tool to solve complicated problems and unlock new insights.
