Now, I have started understanding concepts that my Physics teacher tried teaching me in 11th & 12th standards... She tried very hard though I must admit.. only she failed to spark that interest in me which would have benifited me...
that was 13 years ago...
And now, with Prof. Walter's videos which I just found a couple of days back, I'm out of words to express my elation...

Very good lectures
Only shortcoming is he avoids derivation
He also keeps away from mathematics
