If you're willing to spend the money, I find the lectures at the Teaching Company to be amazing.
The courses on Mozart
, and Understanding the World's Greatest Structures
are some of the greatest lectures I've ever heard in my life.
Currently, my wife, son, and I are all watching the video lecture series of The Everyday Gourmet
right now, and are loving it.
I can't recommend the above 4 courses enough, and they have hundreds more (including math, business, and accounting, which seem to be the interests of the OP).
