Here I give yet more theory to complete the thought of Section 7.2. Here I define isomorphism and prove that isomorphism of vector spaces is an equivalence relation. (we study examples of isomorphism a bit later, and my claim I will prove the coordinate map is an isomorphism in the next lecture is an empty threat)
