Very very good. Those nice pre-Dot-com bubble vibes.

A unique projective space can be defined for any vector space.

The projective space associated with a given vector space $V$ is denoted $\mathbf{P}(V)$.

The definition is to take the vector space, remove the zero element, and identify all elements that lie on the same line, i.e. $\vec{v}=\lambda \vec{w}$

The most important initial example to study is the real projective plane.

In those cases at least, it is possible to add a metric to the spaces, leading to elliptic geometry.

They come up a lot in many contexts, e.g.:

The "greatest common divisor" of two integers $x$ and $y$, denoted $\text{gdc}(x,y)$ is the largest natural number that divides both of the integers.

For example, $\text{gdc}(8,12)$ is 4, because:

This is actually pretty good! Makes a small first step into The missing link between basic and advanced.
