Carl Sagan: An Appreciation

I remember and do not remember Carl Sagan's Cosmos series when I was young. I watched it. I know I liked it. Snippets of it hang in my head. But what I really remember from it, what still is most important about it then and today for me, was how it penetrated into my imagination. The memory of it is less important--the memory fades, but by burrowing into my imagination it became a part of me.
