These are covariant basis vectors.
They are arranged in a row matrix.
Their indexes are in the lower position.

So remember that.

Co. Row. Low.

I'll take vectors in non projected space for 1,000, Alex.

If it were up to me, I'd say introduce Japanese quotation marks to indicate the presence of an index.

Physicists are so fucking weird.

So, they are elements of a cotangent space.
Got it.

So is over the counter physics.

Contra was a video game where a vertically standing person shot people.

Contra. Vertical. Remember..

Also in that game you jump up.

Contra vertical up.

Also the word controvert helps

Contro- contra- contravariant.
Vert-vertical - vertical indexes.

Just have to remember raised.
