Hi
I have just started looking at direct products and came across the following which i don't understand :
the direct product of two spin -up vectors = | 1 > which is in a bigger vector space
I don't understand how the direct product is | 1 > ? and in this case is it always a bigger vector space or the same size as the original vector spaces ?
