I spent some time watching Prof. Strang video's and stuff. Linear Algebra is one of the very few 'real' OpenCourseWare courses available with 34 video lectures online. Real is with video lectures imo. I watched the lecture on Eigenvalues and Eigenvectors . Strang likes to call numbers 'guys', very funny at times. His explanation of eigenvalues is excellent. ( In many ways it is very special that higher education like this is free, I hope it is not taken for granted. )
