physics guy and yukari and /gnmg/ anon have all moved on, what's even the point of it all? Why are we still here? Just to suffer?

So that's the story of the "if you are 24..." poster. Not gonna lie, I cried.

What have I done... L is the smallest subspace of V containing S, and that is, by definition, what it means for a subspace to be spanned by S. That follows from the fact that it is (contained by) the intersection of all such subspaces: suppose a smaller subspace would exist and conclude that L would not be contained in that.
>Also, my professor said this proof method was also used in other areas of mathematics, is this true?
Whenever you are dealing with a proof something that is minimal (maximal) with some property, you try to show that it is smaller (bigger) than any object with the said property.

I hope I understood your questions.

I can't wait to get back to my study city. I feel so fat after spending the christmas time with my parents, and I'll be staying with them for a week and a half more. At least I can escape to libraries and study. They mean well, but I don't want to see any more superhero films etc. Please just let me concentrate!
