  The shoes and socks analogy for inverses of matrix products is probably the cutest thing a math genius has ever said.

  I've been coming back here every 5 or so years to refresh. Just want to say thanks to professor Strang and OCW for making such a great resource available for all.

  I remember being a student and rushing out after class, as these students did. But now at the ripe age of 35, I see these students doing the same and I think "HOW DARE THEY NOT STOP AND APPLAUD FOR SUCH A MASTERFUL PERFORMANCE"

  Funny how this course used to be considered almost a side show until it became central to machine learning.

I just finished abstract algebra and was just watching these lectures because... I don&apos;t need a reason, and I just noticed that now! Prof Strang is amazing. I am glad I can watch these lectures from anywhere and at anytime I want :)
