... I've been thoroughly unimpressed with offerings in all delivery channels ...
Yes, so true - I just had to laugh. These days, it is not the delivery method (that is, distance vs. in-person) that makes or breaks the course. The available technology is good enough to level the field.
@ Bostonian - thank you for pointing to the MIT courses. The video lectures for 'Classical Mechanics' by Prof. Walter Lewin (the first course taken by Young) look great (so much that I am beginning to hope that I have finally found a suitable science course):
