Morley rank

Morley rank is like counting how many different colors of ice cream you have in your sundae. Imagine you have a scoop of vanilla, a scoop of chocolate, and a scoop of strawberry. That means you have 3 colors of ice cream in your sundae.

Well, Morley rank works a similar way but with math equations. It's used to count how many different equations are needed to describe a geometric shape in a certain way. For example, imagine you had a triangle with three angles. To describe the triangle, you might need three equations. That means the Morley rank of the triangle is 3.

Morley rank can get more complicated when you have more complex shapes, but it's still like counting the number of different flavors in your ice cream sundae. Instead of vanilla, chocolate, and strawberry, you might have equations for things like angles, lengths, or curves. By figuring out the Morley rank of a shape, mathematicians can better understand how to describe it and solve problems related to it.
