Im a physics sophomore who went on to take his first course on linear algebra.

Before class:
>A vector is an array of elements which can be visualized as an arrow in n dimensional space

During class:
>What the fuck is this
>Why don't the define vectors as arrows to help develop intuiton
>Why do we just define multiplication like we're retarded without any intuition?
>Oh, that's why
>Kill me

After class:
>A vector is something that behaves like a vector

I somehow feel more of a retard now.
