unpoetic

in a way, in poetry, you try and convey lots of meaning using just a few words. 

rollercoaster -

1. to go up and down like a roller coaster; rise and fall: a narrow road roller-coastering around the mountain; a lightboat roller-coastering over the waves.

2. to experience a period of prosperity, happiness, security, or the like, followed by a contrasting period of economic depression, despair, or the like; the economy was roller-coastering throughout most of the decade. 

which i thought was apt for my last post.

you find the opposite in maths definitions. whole paragraphs of words to describe so little!

Theorem: If S is a finite, non-empty set of vectors in a vector space V, then span(S) is a subspace of V. Further, span(S) is the smallest subspace containing S (in the sense that span(S) is a subspace of every subspace which contains S).
