I high-key thought it was hella cool when he added the two loops together on the picture, subsequently adding the two basis vectors for N(A)^T and creating a dependent vector. I was kind of expecting that to happen just theoretically, but to actually see it happen just blew my puny mind.####[['N(A)^T', 'Mathematical_Related_Concept', 'POS'], ['vector', 'Mathematical_Related_Concept', 'POS'], ['NULL', 'Instructor', 'POS']]
