Khan Academy

The Khan Academy site has links to dozens of short lessons in each of dozens of topics. The author has drawn plaudits from many corners. I’ve added a link on the Resources page, under a new heading of On-Line Lessons.

About Sigurd

Moved to rural Vermont in 1998, recently semi-retired. Intellect-oriented person (I spend a lot of time in my mind, have worked to broaden, regularly, the boundaries of what I pay attention to). One of my current interests is Goethe's approach to understanding the structures of the world (Science) and how it is different from Newton's approach. Goethe tried to stay open to what more the world might tell him of its nature, whereas Newton conceived frameworks that them became a window through which nature is viewed and understood.
