I want to learn very fast through my computer

Comment2 Gentry Marks, August 29, 2009 at 12:30 a.m.:

It would have been nice if at around 30:00 and beyond, the cameraman had gotten some better angles/sharper pictures on the overhead screen pictures.
Besides that, brilliant lecture.

I like this your
site, because it is very educative.

Comment4 Cortney Smith, May 10, 2010 at 5:04 a.m.:

The video is a bit long and it would help if I could see the powerpoint she was teaching off of.

Comment5 elizabeth, August 1, 2010 at 2:52 a.m.:

I love this series because it TEACHES the concepts in the book instead of just repeating them in a lecture format. I can read just fine, I don't need someone to read the book to me. What I (and students in general) need is an explanation of the concepts so that the more advanced application of the concepts in the textbook make sense. It's frustrating that a university charges so much for the honor of having someone pick a textbook (usually not a good one from the student perspective) to be read to you and it's amazing that MIT has posted these lectures for free.

Comment6 FATKHULLA, March 27, 2011 at 4:44 a.m.:

cameraman sucks big time... what's the point of publishing this online if you don't show the most important part of the lecture (those shown in a projector)?


Comment7 abhishek, February 5, 2013 at 10 a.m.:

grt lectures my ceyer mam...... got the concept of mot thks

Comment8 Aftab, March 1, 2013 at 5:40 p.m.:

I totally agree with FATKHULLA, the cameraman has spoiled whole lecture.His primary focus is Ms Sylvia, he is utterly indifferent to what is going on, when madam starts her lecture on projector...

Comment9 Liz, March 3, 2013 at 9:30 p.m.:


Perhaps this will help:


it's the lecture notes for this lecture from the MIT opencoursware site.

The video lectures are very helpful & understandable. I appreciate. God bless you.
