       | I fondly remember learning about OCW for the first time, about
       | 10ish years ago. As a fresh engineer in India, on the cusp of
       | _just_ moving to cheap broadband, at blazing speeds of 5 mbps, I
       | was giddy with excitement of learning from the same lectures an
       | MIT student gets to learn.
       | 
       | While I did not learn much, in terms of actual syllabus, I did
       | get exposed to a refreshing teaching style of exploratory
       | learning.
       | 
       | It helped me learn how to learn, how to approach a subject or
       | problem, how to be confident as a learner.
       | 
       | I have never looked back. Today, I am confident that I can learn
       | any subject, with the right books and practice. That confidence
       | helped me grow as an engineer in my job.
       | 
       | Even today, I view these courses and new ones all the time.
       | 
       | An added side effect was the opening up of learning resources
       | from Stanford, Yale, etc.

         | Raised in the USA, I was extremely fortunate (so many students
         | here and abroad miss out on the sheer good luck of getting
         | several really great teachers in back-to-back succession in
         | school) to have been exposed to some really _amazing_ teachers
         | early in life who taught this _exact_ lesson. Their view of
         | teaching was that if they taught students how to rely on rote
         | book-learning without teaching an accompanying  "thirst for
         | knowledge" and the tools to gain that knowledge, then they'd
         | failed at their job as teachers.
         | 
         | When these universities first started releasing so much of
         | their courseware openly like this, I viewed it as one of the
         | great triumphs of the modern Internet, and a huge boon for
         | humanity. I am glad that humanity now has such an abundance of
         | great learning materials available so readily, and saddened by
         | how few humans choose to avail themselves of such opportunity.

       | These are generally less dense and more tractable than a whole

       | find a bit easier to follow than multiple hours of video.

         | Thermal-Fluids Engineering (2.005 and 2.006) ... or Course 2,

         | 
         | It helps to learn a specific school's curriculum (Stanford and

       | The real value of a professor is that because they know the

       | 
       | This is hard to do when learning by yourself because if you had

       | 
       | I wish there were better communities around learning. Discussion
       | bards, forums, etc. have been terrible substitutes in my opinion
